Update: This article was updated on September 4, 2024 because of a previous error, which was discovered after the preliminary version of the article was posted online. In the Note listing the members of the Wrist and Elbow Research Group of Canada, the text that had read "Thomas T. Goetz, MD, FRCSC" now reads "Thomas J. Goetz, MD, FRCSC"., Background: The primary goal after open reduction and internal fixation of an established scaphoid nonunion is to achieve union. Low-intensity pulsed ultrasound (LIPUS) has been reported to increase the rate of union and to decrease the time to union for multiple fractures and nonunions in clinical and animal models. The evidence for LIPUS in the treatment of scaphoid nonunion, however, is sparse. The aim of this study was to assess whether active LIPUS (relative to sham LIPUS) accelerates the time to union following surgery for scaphoid nonunion., Methods: Adults with a scaphoid nonunion indicated for surgery were recruited for a multicenter, prospective, double-blinded randomized controlled trial. After surgery, patients self-administered activated or sham LIPUS units beginning at their first postoperative visit. The primary outcome was the time to union on serial computed tomography (CT) scans starting 6 to 8 weeks postoperatively. Secondary outcomes included patient-reported outcome measures, range of motion, and grip strength., Results: A total of 142 subjects completed the study (69 in the active LIPUS group and 73 in the sham group). The average age was 27 years, and the cohort was 88% male. There was no difference in time to union (p = 0.854; hazard ratio, 0.965; 95% confidence interval, 0.663 to 1.405). Likewise, there were no differences between the active LIPUS and sham groups with respect to any of the secondary outcomes, except for wrist flexion at baseline (p = 0.008) and at final follow-up (p = 0.043)., Conclusions: Treatment with LIPUS had no effect on reducing time to union in patients who underwent surgical fixation of established scaphoid nonunions., Level of Evidence: Therapeutic Level I .

- Abstract
Background: Infected fracture nonunions often require prolonged treatment and recovery courses. It is unclear whether the bacterial microbiome influences the time to healing as well as the eradication of infection. The goals of this study are (1) to assess the bacterial microbiome affecting infected nonunions and (2) to evaluate the effects of bacterial speciation on associated outcomes., Methods: Between 2006 and 2022, data from 551 adult patients from a single academic institution who presented with a fracture nonunion were analyzed retrospectively for infection. All patients underwent revision surgery with three sets of cultures obtained intra-operatively. Patients with significant intra-operative cultures were grouped into gram-positive and gram-negative culture cohorts. These patients were managed with a standardized protocol involving surgical debridement, nonunion site fixation, and culture-directed antibiotic treatment. Primary outcome was time to fracture union. Secondary outcomes included number of re-operations and eventual amputation or reconstructive surgery., Results: 56 nonunion patients (10 %) were diagnosed with an infected nonunion (44 g-positive, 12 g-negative). Of these, 3 g-positive patients received an amputation or arthroplasty procedure prior to fracture union, and seven were lost to follow-up. There were no significant differences in age, gender, or nonunion site between cohorts. Most nonunions occurred in the lower extremity. The most common bacteria were staph species (54.3 %). 36 g-positive and 10 g-negative patients achieved fracture union. Time to union was on average 158.4 days longer in the gram-negative cohort-but did not reach statistical significance (446.8 days gram-positive, 662.3 days gram-negative, p = 0.69). There was no difference in re-operation rates (1.9 % gram-positive, 2.2 % gram-negative, p = 0.84)., Conclusions: Patients with infected nonunions had wide-ranging bacterial contamination that were treated successfully using a standardized protocol. However, patients with any gram-negative culture trended toward a delay in time to union., Competing Interests: Declaration of competing interest There are no conflicts of interest to disclose from any authors., (Copyright © 2023 The Japanese Orthopaedic Association.

- Abstract
Purpose: Long-term nonunion of the lateral humerus condyle fracture may lead to progressive cubitus valgus, elbow pain and instability, and secondary ulnar neuritis. A number of techniques of osteotomy are available for correction, but each has its disadvantages. The aim of this study was to present a technique of medial trapezoidal osteotomy for correcting nonunion of the lateral humeral condyle with an elbow valgus deformity >20°., Methods: Eight patients (mean age, 7.5 years) with cubitus valgus, after neglected nonunion of a lateral humeral condyle fracture of greater than 2 years duration, were treated with trapezoidal combined osteotomy. The mean interval from the lateral condylar fracture to surgery was 3.1 years. The osteotomy lines were marked on the bone with a template made before surgery. The lateral condyle and osteotomy site were fixed with K-wires, and the elbow joint was immobilized in a plaster brace. Pre- and postoperative carrying angles, range of motion, elbow function, and ulnar nerve neuropathy were analyzed., Results: The mean follow-up was 5.9 years. Union of the lateral condyle was achieved in all patients; 3 healed at 8 weeks, 2 healed at 9 weeks, 2 healed at 10 weeks, and 1 healed at 12 weeks. The mean carrying angle decreased from 30.1° before surgery to 5.8° after surgery. The surgery did not reduce the range of motion at the elbow. According to the Mayo Elbow Performance Score, 6 patients had excellent elbow function, and 2 had good elbow function at the last follow-up. All preoperative ulnar nerve symptoms resolved. One patient had a mild surgical site infection. No other complications occurred., Conclusions: Medial trapezoidal osteotomy appears to be an effective method for treating nonunion of lateral humeral epicondyle fracture with cubitus valgus deformity., Type of Study/level of Evidence: Therapeutic V., (Copyright © 2024 American Society for Surgery of the Hand.

- Abstract
Background: The medial femoral trochlea flap has been used to resurface scaphoids with recalcitrant proximal pole fractures or avascular necrosis, providing vascularized osteochondral tissue with similar morphological characteristics. This article aims to review the contemporary literature on its use for scaphoid reconstruction., Methods: A systematic review of Embase, PubMed, Cochrane Central Register of Controlled Trials, and MEDLINE assessed the use of medial femoral trochlea flaps in scaphoids., Results: Eight studies were included, with 76 patients at a mean age of 26 years. Forty-three patients underwent clinical review, and 10 patients underwent radiographic evaluation, at a mean 23.3 months of follow-up. Flaps were generally performed for proximal pole fractures, avascular necrosis, nonunion, or failure of prior fixation; 94.4% of the flaps united. No marked change in sagittal plane motion was noted; reductions were seen in axial and coronal plane motion. The Disabilities of the Arm, Shoulder, and Hand scores improved from a mean of 25.2 to 11.5. Radiographic markers also improved. A total of 12.3% of patients had unplanned return to theater. Three patients required early revision for vascular thrombosis, and 1 patient suffered a volar carpal dislocation. Three patients underwent salvage procedures for ongoing pain., Conclusions: Although technically demanding, promising early-term to medium-term results are noted with the use of medial femoral trochlea flaps in the scaphoid., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

- Abstract
Background: Small proximal pole scaphoid nonunions present a clinical challenge influenced by fragment size, vascular compromise, deforming forces exerted through the scapholunate interosseous ligament (SLIL), and potential articular fragmentation. Osteochondral autograft options for proximal pole reconstruction include the medial femoral trochlea, costochondral rib, or proximal hamate. This study reports the clinical outcomes of patients treated with proximal hamate osteochondral autograft reconstruction., Methods: A retrospective review identified patients treated with this surgery from 2 institutions with a minimum 6-month follow-up. Clinical outcomes included the Visual Analog Dcale pain score, 12-item Short-Form survey, abbreviated Disabilities of the Arm, Shoulder, and Hand (QuickDASH) score, wrist and forearm range of motion (ROM), radiographic assessment, and complications. We reviewed and compared these outcomes with those of the current published literature., Results: Four patients (mean age: 24 years, 75% men) with a 12.8-month average follow-up (range: 6-20 months) were included. Radiographic union was identified in all cases by 12 weeks (range, 10-12). The average wrist ROM was 67.5% flexion/extension and 100% pronation/supination compared with the contralateral side at the final follow-up. The mean QuickDASH score was 17.6 (SD, 13). No complications were identified., Conclusions: Proximal pole scaphoid nonunion reconstruction using autologous proximal hamate osteochondral graft demonstrated encouraging clinical and radiographic outcomes. Proximal hamate harvest involves minimal donor site morbidity without a distant operative site, uses an osteochondral graft with similar morphology to the proximal scaphoid, requires no microsurgical technique, and permits reconstruction of the SLIL using the volar capitohamate ligament., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: Case 4 included in this series has been previously published elsewhere (Merkow D, Rocks M, Ryan D, Shaughnessy P, Catalano L. Proximal Hamate Autograft for Proximal Scaphoid Pole Reconstruction A Case Report. Bull Hosp Jt Dis (2013). 2022 Jun;80(2):155-159. PMID: 35643475). The prior publication was a case report with a shorter follow-up. The case was included in our current case series with new collected data and a longer follow-up and represents new original work/outcomes of one of the authors (L.W.C.).

- Abstract
Purpose: Exploring the therapeutic effects of Ni-Ti shape memory alloy four-corner arthrodesis concentrator (NT-FCAC) in treating scaphoid nonunion advanced collapse (SNAC) and providing a decade-long follow-up report., Materials and Methods: Twenty-six patients with SNAC underwent scaphoidectomy, along with four-corner arthrodesis fusion involving the capitate, lunate, triquetrum, and hamate, using NT-MFCAC. Grip strength was measured using a Jamar dynamometer, while wrist joint mobility was assessed using a goniometer. Preoperative and postoperative assessments were conducted using the Quick Disabilities of the Arm, Shoulder, and Hand (Quick DASH) questionnaire to monitor limb functionality restoration. Pain levels at the wrist joint were evaluated using the visual analog scale (VAS). Postoperative wrist bone fusion status was assessed through anteroposterior and lateral radiographs of the wrist joint., Results: After a 3-month postoperative period, all 26 patients exhibited osseous union at the wrist joint. Over a follow-up spanning 10-15 years, no severe postoperative complications were observed in any patient. Grip strength in the affected side of all patients recovered to 81.96% compared to the healthy side, while wrist joint mobility in the affected side reached over 60% of the healthy side's functionality. VAS scores decreased significantly from 5.85 ± 0.73 preoperatively to 0.19 ± 0.40 at the final follow-up; Quick DASH scores reduced from 69.88 ± 5.12 preoperatively to 6.30 ± 1.25 at final follow-up. Statistically significant differences were noted in VAS and Quick DASH scores for all patients (p < 0.05). However, beyond 60 months postoperatively, subsequent follow-ups did not yield statistically significant differences in VAS and Quick DASH scores for all patients (p > 0.05)., Conclusions: Utilizing NT-FCAC for SNAC treated with four-corner arthrodesis fusion results in a high rate of wrist bone fusion, preserving a significant portion of wrist joint function and exhibiting favorable long-term outcomes. This approach is suitable for treating patients with SNAC requiring four-corner arthrodesis fusion.

- Abstract
Background: Scaphoid nonunion advanced collapse (SNAC) injuries are frequently associated with irreversible degenerative wrist arthritic changes that necessitate surgical intervention. Midcarpal fusion remains the mainstay of the management of SNAC II and III injuries. A successful four-corner fusion (4CF) relies on a stable lunate-capitate fusion (LCF). There have been reports of management relying solely on LCF. The outcomes of LC- and 4 C-fusions in SNAC injuries were not widely documented. The objective of this research is to provide valuable insights into the effectiveness of both fusion procedures in the management of SNAC II and III wrist injuries, with a focus on reporting associated complications, functional and radiological outcomes., Patients and Methods: This retrospective study encompassed 65 patients diagnosed with SNAC II and III wrist injuries who underwent limited wrist fusion procedures between 2015 and 2024, with a minimum of 2 years of postoperative follow-up. Exclusion criteria encompassed patients with carpal instability, prior wrist surgical interventions, and scapholunate advanced collapse. Following the fusion procedure performed, patients were stratified into two groups: the LCF group consisting of 31 patients, and the 4CF group comprising 34 patients. Preoperative and intraoperative data were retrieved from the patient's medical records. At their final follow-up appointments, patients underwent comprehensive radiographic and clinical evaluations. Clinical outcomes including hand grip strength, range of motion, the Disabilities of the Arm, Shoulder, and Hand Score, and the Mayo Modified Wrist Score, were compared between groups. Any associated complications were reported., Results: The average healing time was 74.7 ± 15.6 and 72.2 ± 13.2 days for the LCF and 4CF groups, respectively. At the final visit, all patients showed functional improvement relative to their preoperative status, with comparable wrist range of motions observed in both groups. The functional wrist scores were slightly better in the LCF patients (P > 0.05). The average grip strength was significantly greater in the LCF group (P = 0.04), with mean strength values of 86.8% and 82.1% of the contralateral side, for the LCF and 4CF groups, respectively., Conclusion: The LCF is not less efficient than the 4CF in the treatment of SNAC II and III wrist injuries. Through a less time-consuming procedure, LCF can efficiently provide comparable results to 4CF., Level of Evidence: level IV evidence., (© 2024. The Author(s).)

- Abstract
Purpose: To assess the use of bone marrow aspirate (BM) and bone marrow aspirate concentrate (BMAC) in the treatment of long-bone nonunion and to understand mechanism of action., Methods: A systematic review of PubMed and EBSCOHost was completed to identify studies that investigated the use of BM or BMAC for the diagnosis of delayed union and/or nonunion of long-bone fractures. Studies of isolated bone marrow-mesenchymal stem cells (BM-MSCs) and use in non-long-bone fractures were excluded. Statistical analysis was confounded by heterogeneous fracture fixation methods, treatment history, and scaffold use., Results: Our initial search yielded 430 publications, which was screened down to 25 studies. Successful treatment in aseptic nonunion was reported at 79-100% (BM) and 50-100% (BMAC). Septic nonunion rates were slightly better at 73-100% (BM) and 83.3-100% (BMAC). 18/24 studies report union rates > 80%. One study reports successful treatment of septic nonunion with BMAC and no antibiotics. A separate study reported a significant reduction in autograft reinfection rate when combined with BMAC (P = 0.009). Major adverse events include two deep infections at injection site and one case of heterotopic ossification. Most studies note transient mild donor site discomfort and potential injection site discomfort attributed to needle size., Conclusion: The current literature pertaining to use of BM/BMAC for nonunion is extremely heterogeneous in terms of patient population and concomitant treatment modalities. While results are promising for use of BM/BMAC with other gold standard treatment methodologies, the literature requires additional Level I data to clarify the impact of role BM/BMAC in treating nonunion when used alone and in combination with other modalities., Level of Evidence: Level III., (© 2024.

- Abstract
Background: Delayed union and nonunion of the scaphoid is a common complication often requiring surgical reconstruction and bone grafting. Our goal was to systematically assess the healing time and clinical outcomes following arthroscopic-assisted versus open non-vascularized bone grafting of the scaphoid., Methods: A comprehensive search of the MEDLINE, Embase, CINAHL (Cumulative Index to Nursing and Allied Health Literature), and Cochrane Central databases was completed from inception to September 2023. We included randomized trials and observational studies that reported outcomes following scaphoid delayed union/nonunion comparing arthroscopic-assisted vs. open non-vascularized bone grafting. Two reviewers independently extracted data and assessed the risk of bias. One investigator assessed certainty of evidence and a senior investigator confirmed the assessment. We pooled effects using random-effects models, when possible, for all outcomes reported by more than 1 study., Results: Overall, 26 studies and 822 patients were included in the study. Very low certainty evidence demonstrated that arthroscopic-assisted surgery may decrease healing time compared to open surgery (weighted mean difference [WMD] -7.8 weeks; 95%CI -12.8 to -2.8). Arthroscopic bone grafting did not result in an improvement in union rate (relative risk 1.01; 95%CI 0.9 to 1.09). The pooled data in arthroscopic graft group showed mean time to union of 11.4 weeks (95%CI: 10.4 to 12.5) with union rate of 95% (95%CI 91-98%). A single comparative study reported very low certainty evidence that arthroscopy-assisted vs. open surgery may not have an effect on pain relief (MD 0 cm, 95%CI -0.4 to 0.5 on VAS 10 cm for pain) or improving function (MD -1.2, 95% CI -4.8 to 2.3 on 100 points DASH)., Conclusion and Future Directions: Our results suggest that arthroscopic-assisted non-vascularized bone grafting may be associated with improved average weeks to heal in comparison with open surgery for scaphoid delayed union/nonunion reconstruction with overall comparable union rates. There is insufficient evidence to assess the effects of arthroscopic-assisted reconstruction on union rate, time to union, and patient-reported outcomes in patients with other important nonunion characteristics such as established humpback deformity., (© 2024.

- Abstract
Objectives: To determine (1) the rate of positive cultures in presumed aseptic nonunions, (2) the rate and microbial spectrum of positive cultures that represented occult infection, and (3) rates of nonunion healing., Design: Retrospective cohort study., Setting: Tertiary referral center., Patients Selection Criteria: Adult patients with a presumed aseptic nonunion treated with single-stage revision between 2002 and 2022., Outcome Measures and Comparisons: The rate of positive cultures compared for 2 protocols: old: 1-2 samples cultured 7 days versus new: 5 samples cultured 14 days. The rate of positive cultures meeting occult infection criteria with the new protocol (≥2 samples with phenotypically indistinguishable microorganisms, or ≥1 sample with a high virulent microorganism). Nonunion healing rates between protocols and between groups based on culture results with the new protocol., Results: One hundred seventy-nine patients were included. The rate of positive cultures was 14% (n = 15/105) with the old protocol and 51% (n = 38/74) with the new protocol (P < 0.001). With the new protocol, the rate of positive cultures meeting occult infection criteria was 19% (n = 14/74), and coagulase-negative staphylococci (48%) and Cutibacterium acnes (38%) were the most common microorganisms. Nonunion healing rates after the primary revision did not differ between protocols (old: 82% vs. new: 86%, P = 0.41) and groups based on culture result (sterile: 86% vs. occultly infected: 93%, P = 0.66). The final overall nonunion healing rate was 97%., Conclusions: Occult infections were identified in 1 in 5 presumed aseptic nonunions using a standardized protocol with 5 intraoperative samples cultured 14 days and were predominantly caused by slow growing, gram-positive microorganisms. The local spectrum and antimicrobial sensitivity of occult infections should be considered when developing empiric antimicrobial protocols. Patients with presumed aseptic nonunions can expect high healing rates, regardless of the culture result., Level of Evidence: Diagnostic Level III.

- Abstract
Objective: Clinical concerns exist regarding the quality of bony consolidation in the context of the induced membrane technique. This study evaluates the clinical process of bone grafting in the second stage of induced membrane bone union in patients with tibial bone defects to infer the possibility of non-union and establish a reliable and effective evaluation method combined with computed tomography (CT) to assess fracture healing., Methods: Patients with tibial bone defects who underwent the induced membrane technique at our hospital between February 2017 and February 2020 were retrospectively analyzed. The Hounsfield unit (HU) values of the patients were evaluated at different times during the second stage of bone grafting. Bone healing at the boundary value of the 120 HU output threshold (-1024 HU-3071 HU) was directionally selected, and the changes in the growth volume of union (new bone volume [selected according to HU value]/bone defect volume) were compared with analyzing individual class bone union. Method 1 involved X-rays revealing that at least three of the four cortices were continuous and at least 2 mm thick, with the patient being pain free. For Method 2, new bone volume (selected according to HU value/bone defect volume) at the stage was compared with analyzing individual class healing. Receiver operating characteristic curve analysis was used for Methods 1 and 2., Results: A total of 42 patients with a segmental bone defect with a mean age of 40.5 years (40.5 ± 8.3 years) were included. The relationship between bone graft volume and time variation was analyzed by single factor repeated variable analysis (F = 6.477, p = 0.016). Further, curve regression analysis showed that the change in bone graft volume over time presented a logarithmic curve pattern (Y = 0.563 + 0.086 × ln(X), Ra
2 = 0.608, p = 0.041). ROC curve analysis showed that Method 2 is superior to Method 1 (AUC: 86.3% vs. 68.3%, p < 0.05)., Conclusion: The induced membrane technique could be used to treat traumatic long bone defects, with fewer complications and a higher healing rate. The proposed imaging grading of HU (new bone volume/bone defect volume) can be used as a reference for the quality of bony consolidation with the induced membrane technique., (© 2024 The Author(s).

- Abstract
The diagnosis and treatment of non-unions still represents an interdisciplinary challenge. Therefore, prevention, early detection and specific treatment are of great importance. Non-unions of the upper extremities, although less common than that of the lower extremities, requires special attention for successful treatment due to the central role of the shoulder girdle and arm in day to day activities. Successful treatment of non-unions requires a comprehensive evaluation of the patient's medical history, a thorough clinical examination and in particular radiological imaging. In order to effectively treat the pseudarthrosis it is crucial to distinguish between pseudarthroses that are suspected to be due to infections and those that are not. This article presents a treatment algorithm for managing both pseudarthrosis due to infection and pseudarthrosis without infection in the upper extremities., (© 2024.

- Abstract
Background: The nonunion rate for atypical femoral fractures (AFF) is known to be higher than that for typical fractures of the femur. We performed a meta-analysis to determine the incidence of nonunion necessitating reoperation following fixation for AFF and compare the rates according to the fracture site (subtrochanter or midshaft)., Methods: A total of 742 AFFs from 29 studies were included. A proportion meta-analysis utilizing a random-effects model was conducted to estimate the prevalence of nonunion. The outcomes were the incidence of reoperations that included osteosynthesis. To determine the association of nonunion with patient mean age or average duration of bisphosphonate use, meta-regression analysis was done., Results: In proportion meta-analysis, the estimated pooled prevalence of nonunion was 7% (95% confidence interval [CI], 5%-10%) from all studies. There was a significant difference in nonunion rate between the 2 groups (I
2 = 34.4%, p = 0.02); the estimated prevalence of nonunion was 15% (95% CI, 10%-20%) in subtrochanteric AFFs and 4% (95% CI, 2%-6%) in midshaft AFFs. From meta-regression analysis, significant correlations were identified between nonunion rate and patient mean age (coefficient: -0.0071, p = 0.010), but not in the average duration of bisphosphonate use (coefficient: -0.0024, p = 0.744)., Conclusions: A notable disparity existed in the nonunion rate among subtrochanteric AFFs and midshaft AFFs group. Therefore, it is critical for orthopedic surgeons to consider the complexity and challenges associated with AFF and to estimate the proper possibility of nonunion according to the fracture site., Competing Interests: CONFLICT OF INTEREST: No potential conflict of interest relevant to this article was reported., (Copyright © 2024 by The Korean Orthopaedic Association.)- Published

- Abstract
Background: Clinical repair of critical-sized bone defects (CBDs) in the tibial diaphysis presents numerous challenges, including inadequate soft tissue coverage, limited blood supply, high load-bearing demands, and potential deformities. This study aimed to investigate the clinical feasibility and efficacy of employing 3D-printed prostheses for repairing CBDs exceeding 10 cm in the tibial diaphysis., Methods: This retrospective study included 14 patients (11 males and 3 females) with an average age of 46.0 years. The etiologies of CBDs comprised chronic osteomyelitis (10 cases) and aseptic non-union (4 cases), with an average defect length of 16.9 cm. All patients underwent a two-stage surgical approach: (1) debridement, osteotomy, and cement spacer implantation; and (2) insertion of 3D-printed prostheses. The interval between the two stages ranged from 8 to 12 weeks, during which the 3D-printed prostheses and induced membranes were meticulously prepared. Subsequent to surgery, patients engaged in weight-bearing and functional exercises under specialized supervision. Follow-up assessments, including gross observation, imaging examinations, and administration of the Lower Extremity Functional Scale (LEFS), were conducted at 3, 6, and 12 months postoperatively, followed by annual evaluations thereafter., Results: The mean postoperative follow-up duration was 28.4 months, with an average waiting period between prosthesis implantation and weight-bearing of 10.4 days. At the latest follow-up, all patients demonstrated autonomous ambulation without assistance, and their LEFS scores exhibited a significant improvement compared to preoperative values (30.7 vs. 53.1, P < 0.001). Imaging assessments revealed progressive bone regeneration at the defect site, with new bone formation extending along the prosthesis. Complications included interlocking screw breakage in two patients, interlocking screw loosening in one patient, and nail breakage in another., Conclusions: Utilization of 3D-printed prostheses facilitates prompt restoration of CBDs in the tibial diaphysis, enabling early initiation of weight-bearing activities and recovery of ambulatory function. This efficacious surgical approach holds promise for practical application., (© 2024. The Author(s).)

- Abstract
Objective: Rib fracture non-union is an uncommon complication of traumatic rib fractures. Our objective was to perform a scoping review of the literature for the management of rib fracture non-union. This included analysis of the variations in surgical technique, complications experienced, and reported outcomes., Methods: We conducted a scoping review and searched databases (MEDLINE, CINAHL, and Embase). We performed abstract and full-text screening, and abstracted data related to pre-operative assessment, surgical technique, complications, and reported outcome measures., Results: We included 29 articles of which 19 were case reports and 10 were case series. The data quality was generally heterogeneous. The studies included 229 patients and the commonest symptoms of rib fracture non-union included chest pain, clicking, dyspnea and deformities. The patients underwent surgical management of rib fracture non-union (excluding first rib fractures) using various techniques. The majority used surgical stabilization of rib fracture with or without a graft. The reported outcomes were inconsistent between studies, but showed high rates of union (>94 %), reduction in reported VAS scores, and improved return to work when included. Implant failure occurred in 10 % of the 229 total patients reported in our studies, the re-operation rate was 13 %, and the overall complication rate was 27 %., Conclusion: Surgical management of rib fracture non-union often involving locking plates and screws with or without a graft has been shown in several case reports and series as an effective treatment with acceptable implant failure and complication rates. Surgical management is therefore a viable option for symptomatic patients. Further research is required to determine optimal management strategies that further reduce surgical complications for these patients., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

- Abstract
Ulnar-shortening osteotomy is a reliable solution to treat ulnar impaction syndrome, but it has a significant rate of nonunion as a known complication. Generally nonunion after the procedure is attributed to noninfectious causes. When infections happen, they follow the microbiological trends of nonunions elsewhere in the body. We present a case of ulnar-shortening osteotomy using an oblique-cut osteotomy system that resulted in septic nonunion. At the time of revision surgery, Cutibacterium acnes and Staphylococcus hominis were isolated from the osteotomy site. The patient was successfully treated using intravenous antibiotics and the two-stage Masquelet technique and eventually went on to bony union. As C acnes is rarely encountered in this context, this report highlights the need to consider all possible pathogens in the workup of a potentially septic nonunion. Surgeons should consider bacteria such as C acnes that require prolonged incubation for isolation from cultures, which may not be part of many institutions' usual protocol.

- Abstract
Background: Humeral nonunions have devastating negative effects on patients' upper extremity function and health-related quality of life. The objective of this study was to identify factors independently associated with 30-day complication, hospital readmission, and reoperation after surgical treatment of humeral nonunions., Materials and Methods: A retrospective case-control study was performed using the American College of Surgeons National Surgical Quality Improvement Program database by querying the Current Procedural Terminology codes for patients who underwent humeral nonunion repair from 2011 to 2020. The study outcomes were 30-day complication, hospital readmission, and reoperation., Results: Of the 1306 patients in our cohort, 135 patients (10%) developed a complication, 66 patients (5%) were readmitted to the hospital, and 44 patients (3%) underwent reoperation during the 30-day postoperative period. Multivariable logistic regression analysis showed that older age, longer operative time, partially dependent functional status, congestive heart failure, bleeding disorder, and contaminated wound classification were associated with 30-day complication after humeral nonunion repair. Older age and disseminated cancer were associated with 30-day reoperation after humeral nonunion repair. Disseminated cancer was associated with 30-day readmission after humeral nonunion repair., Conclusion: Using a large database over a recent 10-year period, we identified demographic and comorbid factors independently associated with episode of care adverse events after humeral nonunion repair. Patients 50 years or older had approximately three times the incidence of complications, readmissions, and reoperations in the first month after humeral nonunion repair compared with patients younger than 50 years. Our findings are relevant for preoperative risk stratification and counseling. [ Orthopedics . 2024;47(4):e181-e187.].

- Abstract
Purpose: Lateral humeral condyle nonunion in children is a rare condition. The treatment protocol for nonunion of lateral humeral condyle remains controversial due to the potential complication. This study reports long-term functional outcomes of the nonunion of the lateral humeral condyle fracture. In addition, we identified the prognostic factors for nonunion of the lateral humeral condyle fracture., Methods: We conducted a multicentre retrospective cohort study of nonunion of lateral humeral condyle between January 1995 and December 2022. The patient's preoperative demographic information was reviewed. Potential risk factors of poor functional outcome, such as age, duration from initial injury, and fracture displacement, were retrieved. Functional outcomes at the latest follow-up visit were evaluated using the Mayo Elbow Performance Score (MEPS). Multivariable linear regression was deployed to evaluate the association of potential risk factors with the functional outcome., Results: A total of 63 patients from eight medical centers were included, of which 60 were surgically treated. Patients' average age was 7.3 years old, with a mean follow-up duration of seven years. All nonunion cases were successfully treated, resulting in a normalized humeroulnar angle. The rate of AVN was 16.7%. All patients reported excellent range of motion and MEPS at the latest follow-up. Multivariable linear regression demonstrated that Fracture displacement (β = -0.88, 95% CI -1.55 to -0.22, p = 0.010) and duration from initial injury (β = -0.09, 95% CI -0.17 to -0.02, p = 0.010) were statistically significant factors influencing functional outcome of lateral humeral condyle nonunion., Conclusions: Initial fracture displacement and duration from the initial injury are statistically significantly associated with elbow function in lateral humeral condyle nonunion. However, the effect size for these factors is relatively small and does not reach clinical significance. Despite this, the functional outcome is excellent in all patients, with an average follow-up duration of seven years., (© 2024. The Author(s) under exclusive licence to SICOT aisbl.)

- Abstract
Purpose: Although proximal row carpectomy (PRC) has increasingly been shown to have superior features to four-corner fusion (4CF), individual surgeons may remain convinced of the superiority of one procedure based on personal experience and individual biases. Hence, we sought to perform an updated meta-analysis with some of the largest studies to date to compare outcomes and complications between these procedures in the treatment of scapholunate advanced collapse and scaphoid nonunion advanced collapse wrists., Methods: A systematic review and meta-analysis was performed per Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. PubMed/MEDLINE, Embase, Web of Science, and Cochrane were queried for articles on PRC and 4CF performed for scapholunate advanced collapse and scaphoid nonunion advanced collapse wrist. Primary outcomes included wrist range of motion; grip strength; outcome measures, including Disabilities of Arm, Shoulder, and Hand and Quick Disabilities of Arm, Shoulder, and Hand scores, Patient-Rated Wrist and Hand Evaluation, and visual analog scale pain scores; and surgical complications., Results: Sixty-one studies reported on 3,174 wrists, of which 54% were treated with PRC and 46% were treated with 4CF. The weighted mean follow-up was 61 months (range, 12-216 months). Meta-analysis comparing PRC and 4CF demonstrated that PRC had significantly greater postoperative extension; ulnar deviation; postoperative improvement in extension, flexion, ulnar deviation; and visual analog scale score. No comparisons showed significant differences in grip strength. The percentage of wrists requiring arthrodesis was 5.2% for PRC and 11% for 4CF. There was an 8.9% (57/640 wrists) 4CF nonunion rate and 2.2% (17/789) hardware removal rate after 4CF., Conclusions: In the treatment of scapholunate advanced collapse and scaphoid nonunion advanced collapse wrists, PRC results in better outcomes and a lower complication rate compared to 4CF., Type of Study/level of Evidence: Therapeutic IV., Competing Interests: Conflicts of Interest K.A.H. is a paid consultant for LinkBio Corp.

- Abstract
Purpose: To introduce anterior peri-sacroiliac joint osteotomy (APSJO) through the lateral-rectus approach (LRA) for treating pelvic fracture malunion and nonunion, and to evaluate the safety, feasibility, and potential effectiveness., Methods: Data of 15 patients with pelvic fracture malunion and nonunion who underwent treatment by APSJO were selected and analyzed. The reduction quality was assessed using the Mears and Velyvis criteria, while the pre-operative and post-operative function was revealed by the Majeed scoring system. The British Medical Research Council (BMRC) grading system was recruited for the evaluation of lumbosacral plexus function., Results: The average operative duration was 264.00 ± 86.75 min, while the intra-operative blood loss was 2000 (600, 3000) mL. Anatomical reduction was complete in three cases, satisfactory in ten cases, and unsatisfactory in two cases. Among the seven patients with lumbosacral plexus injury, the pre-operative Majeed grades were good in two cases, fair in two cases, and poor in three cases, while the post-operative Majeed grades were excellent in three cases, good in three cases, and fair in one case. Muscle strength recovered to M5 in two cases, M4 in three cases, and showed no recovery in two cases. The pre-operative Majeed grades were good in five cases, fair in two cases, and poor in one case of the series without lumbosacral plexus injury, while the post-operative Majeed grades were excellent in seven cases and good in one case., Conclusion: APSJO through LRA may be a feasible strategy for treating pelvic fracture malunion and nonunion with promising application., (© 2024.

- Abstract
Background: Grade III open tibial diaphyseal fractures are challenging to treat and controversy exists on whether to treat them with an intramedullary nail (IMN) or a circular frame (CF). This study aims to compare outcomes for intramedullary nail and circular frame in the treatment of open tibial diaphyseal fractures., Methodology: Retrospective study at a major trauma center of all patients admitted with a grade III open tibial diaphyseal fracture between January 2016 and January 2022. The primary outcome measures were major complications: non-union, malunion, refracture, DBI and amputation. Secondary outcome measures were time to union and reoperation rates., Results: Fifty-five patients were included in the study, 32 patients in CF group and 23 patients in IMN group. There were no significant differences in the baseline demographics of patients in both groups. Major complications were recorded in 13 limbs (54%) in IMN group and in 18 limbs (56%) in CF group which were not statistically significant (p = 0.797). Deep bone infection rates were noted in 4 (12.5%) in the CF group, compared to 1 (4%) in IMN group; however, the result was not statistically significant (p = 0.240). Amputation rates as a result of infected non-unions were seen in 1 limb (4%) in IMN group and 2 limbs (6%) in CF group (p = 0.99). Median time to union was significantly shorter in IMN group at 30 weeks compared to 30 weeks for CF group (p = 0.04)., Conclusion: IMN should be the treatment of choice in the treatment of grade III open tibial diaphyseal fracture, but CF should be considered for delayed treatment and in patients with bone loss., (© 2024.

- Abstract
Introduction: Recombinant human Bone morphogenetic proteins have been used for the treatment of nonunions with promising results. We have been investigating both experimentally and clinically the efficacy of the rhBMP-2 with the macro / micro-porous hydroxyapatite carrier granules on the potency on the reconstruction of long bone defect. The purpose of this study was to prospectively evaluate the efficacy and safety of this specific rhBMP-2 with HA carrier granules mixed with autologous cancellous bone in patients with nonunion and bone defect resulted from the fracture related infection., Materials and Methods: This was a retrospective review of a prospective cohort at a university hospital. Patients diagnosed with nonunion under the definition of the United States Food and Drug Administration with bone defect after long bone fractures were enrolled from January 2020 to February 2021. We included patients with atrophic and oligotrophic nonunion, and hypertrophic nonunion with malalignment that needed to be corrected. The other patient group was consisted of segmental bone defect resulted from FRI. The maximum amount of rhBMP-2 allowed in this clinical study was 6 mg and was added to autologous bone at a 1:1 ratio. Autologous bone was added to the mixture if the volume of mixed graft was insufficient to fill the bone defect. Patients were followed 3, 6, and 12 months post-operatively. Each visit, a radiograph was taken for assessment. Visual analog scale (VAS), questionnaire for quality of life (SF-12 physical component summary [PCS], mental component summary [MCS]), and weight-bearing status were collected for functional outcome assessment. Drug safety was assessed by examining BMP-2 antibodies., Results: Of the 24 enrolled patients (mean age: 57 years), 15 (62.5 %), 2 (8.33 %), and 7 (29.17 %) presented atrophic nonunion, hypertrophic nonunion with deformity, and bone defect after fracture related infection, respectively. Thirteen patients had nonunion in the femur, 9 in the tibia, and 1 in the humerus and radius. The average amount of harvested autologous bone was 9.25 g and 4.96 mg of rhBMP-2. All 24 patients achieved union after 1-year follow up. The union rate was 95.83 % and 100 % at 6 and 12 months postoperatively, respectively. Preoperative SF-12 PCS (mean: 34.71) improved at 6 and 12 months postoperatively, respectively. Preoperative SF-12 MCS (mean: 42.89) improved 12 months postoperatively (49.13, p = 0.0338). Change of VAS was statistically significant 3 months postoperatively (p = 0.0012). No adverse effects or development of BMP-2 antibodies were observed., Conclusion: BMP-2 combined with autogenous bone resulted in excellent radiographical and functional outcomes in a relatively small prospective series of patients with nonunion and bone defect, without adverse effects. Further investigations are necessary to support our finding and optimize treatment strategies in nonunion patients., Competing Interests: Declaration of competing interest None., (Copyright © 2024.

- Abstract
BACKGROUND Nonunion of a rib fracture can cause chronic pain, and pharmacological pain management may lead to medication dependence. This report describes a 54-year-old man with a chronic cough and painful nonunion fracture of the left posterior 8th rib, managed with minimally invasive surgery and a rib splint. CASE REPORT A 54-year-old man presented with chronic cough-induced left chest wall pain. Three-dimensional chest computed tomography (CT) scan showed a nonunion of a fracture of the left posterior 8th rib. After medical management failure, we proposed a surgical approach with the aim to remove the tissue comprising the nonunion, release the nerve, and stabilize the bone stumps. To avoid the adverse effects of a large incision, we designed a minimally invasive strategy based on ultrasound fracture localization and the use of an intramedullary splint. The pain disappeared immediately after surgery. The patient was discharged in 24 hours. At 6-week follow-up, he was still asymptomatic, and a new CT scan reconfirmed the correct splint position. From the immediate postoperative evaluation until the last follow-up visit, he consistently reported full satisfaction. CONCLUSIONS This report has highlighted the challenges of management of chronic pain in nonunion of a rib fracture, and has described the use of a minimally invasive surgical approach. In this single case, our tailored surgical strategy achieved definitive success in pain management, minimizing postoperative complications/adverse effects and avoiding the addition of pain medications despite a 24-hour hospital stay. Our goal is to share an alternative solution for colleagues facing similar cases.

- Abstract
Introduction: Bone grafts for scaphoid nonunion with deformity include cortcicocancellous or pure cancellous bone grafts. This study compared the outcomes between two types of bone grafts when employing a volar locking-plate in patients with scaphoid nonunion with dorsal intercalated segmental instability (DISI)., Patients and Methods: This retrospective study included 34 patients with scaphoid nonunion and DISI due to humpback deformity treated between March 2017 and January 2022. Two types of bone grafts were obtained from iliac crest. Twenty of the corticocancellous (CC) group underwent a wedge-shaped graft, while 14 patients of the pure cancellous (C-only) group received graft chips. In both groups, a 1.5-mm anatomically pre-contoured locking plate was used for fixation. Radiographic evaluations included the union rate and carpal alignment including scapholunate angle (SLA), radiolunate angle (RLA), intrascaphoid angle (ISA) and scaphoid height to length ratio (HLR). Clinical assessments encompassed wrist range-of-motion, grip strength, and patient-reported outcomes., Results: Nineteen of the 20 patients in the CC group and 12 of the 14 patients in the C-only group respectively, achieving osseous union. The mean follow-up period in CC group was 14.7 (range, 12 ∼ 24) months and that in C-only group was 12.6 (range, 12 ∼ 15) months. Postoperatively, there were no significant intergroup differences of radiographic parameters including SLA (CC; 49.9° ± 6.7° vs. C-only; 48.9° ± 3.5°, P = 0.676), RLA (1.7° ± 6.4° vs. 2.4° ± 3.3°, P = 0.74), ISA (36° ± 7.5° vs. 36.6° ± 12.2°, P = 0.881), and HLR (0.54 ± 0.09 vs. 0.53 ± 0.05, P = 0.587). Clinical outcomes, including the flexion-extension arc (137° ± 30° vs. 158° ± 33°, P = 0.122), grip strength (93.4 % ± 15.4% vs. 99.5 % ± 16.7 %, P = 0.39), Quick Disabilities of the Arm, Shoulder, and Hand scores (11.2 ± 8.3 vs. 12.5 ± 7.7, P = 0.74) and Mayo Wrist Scores (81.2 ± 13.1 vs. 89 ± 11.4, P = 0.242) also showed no significant intergroup differences., Conclusions: Volar locking-plate fixation with pure cancellous bone grafts achieved outcomes comparable to those achieved with corticocancellous bone grafts in scaphoid nonunion with deformity, possibly due to the biomechanical advantages of the volar plate to provide structural supports., Competing Interests: Declaration of competing interest None., (Copyright © 2024 Elsevier Ltd.

- Abstract
Objectives: This study aimed to assess clinical, functional and radiological outcomes after three-corner arthrodesis in patients suffering from symptomatic scapholunate or scaphoid non-union advanced collapsed wrists. We hypothesised that three-corner arthrodesis provided satisfactory clinical and radiological results in the long term., Material and Methods: This was a retrospective study of 13 patients (14 wrists) who underwent a three-corner arthrodesis between March 2004 and January 2019 with a mean follow-up of 6,7 years. Clinical assessment consisted of wrist motion, grip strength, pain and functional scores (Quick-DASH, PRWE, MWS). All complications and surgical revisions were investigated. Radiographic assessment searched for union, evaluated carpal height and ulnar translation, lunate tilt and occurrence of radio-lunate arthritis., Results: At the last follow-up Quick-DASH and PRWE scores were 24,87(± 17.2) and 47.4 (± 26.9) respectively and were significantly improved. Wrist motion was 35°, 32°, 10° et 24° of flexion, extension, radial and ulnar deviation respectively. Union was obtained for 13 (92,9%) wrists. The mean radiolunate angle was 11° (-17°-34°). Three patients needed reintervention, which 2 consisted of total wrist arthrodesis due to persisting pain. Mild signs of radio-lunate arthritis were found in three patients., Conclusion: Three-corner arthrodesis seemed to provide satisfactory long-term functional outcomes. The union rate was high and even patients with signs of radio-lunate arthritis still had improved outcomes at the last follow-up. It could be a part of surgical options in wrists with radio- and midcarpal arthritis, among other procedures., Competing Interests: Declaration of competing interest The authors have declared no conflict of interest., (Copyright © 2024.

- Abstract
Introduction: The subtrochanteric region is known for its unique biomechanical properties that contribute to challenges in fracture reduction. To ensure optimal fracture healing, achieving robust mechanical stability is essential. There are very few studies in the literature describing the treatment of subtrochanteric fracture nonunion., Purpose: To analyze the outcomes of two techniques of revision fixation of nonunion in subtrochanteric femur fracture, namely, nail-plate fixation and plate-structural fibula graft fixation., Methods: This was a retrospective analysis of subtrochanteric femur nonunion between January 2011 and December 2019. The demographic details, details of the index surgery, details of the revision surgery and the time to final union were collected. The nonunion was divided based on the level of the fracture into high subtrochanteric and low subtrochanteric. Two revision techniques were used: plate-structural fibula graft for high subtrochanteric and nail-plate construct for low subtrochanteric femur fractures RESULTS: Out of the 54 patients that were included, there was malalignment in 53.70 %, medial comminution in 46.3 %, distraction at the fracture site in 44.4 %, lateral trochanteric wall break in 37.03 % and implant failure in 70.37 % of the patients. There were 20 high subtrochanteric and 34 low subtrochanteric fractures. Union was achieved in 53 patients (98.14 %). The mean LEFS score was 71.4 in the nail-plate group and 66.2 in the plate-structural fibula graft group (p 0.003)., Conclusion: The treatment of subtrochanteric femur fracture nonunion can be a daunting task. The goal is to correct the varus and restore the medial support which will prevent the occurrence of collapse and another failure. We were able to achieve this with both the nail-plate and the plate- structural fibula graft revision methods., Competing Interests: Declaration of competing interest All authors confirm that there is no conflict of interest, (Copyright © 2024 Elsevier Ltd.

- Abstract
Introduction: In this study the tibial shaft fracture non unions in diabetes mellitus are evaluated with percutaneous autologous platelet gel supplementation to accelerate union are compared with individually matched control group with autologous iliac crest bone marrow aspirate injection., Material and Methods: This present study was carried out on tibial non unions in diabetic patients recruited in an ongoing longitudinal study over a period of 2006 to 2017, treated by one surgeon at one institute, are included in this report. Each of 18 established tibial atrophic, aseptic non unions treated by percutaneous autologous platelets and iliac crest bone marrow aspirate were followed up on regular basis up till 9 months. The healing of non union was assessed clinically by painless full weight bearing and the radiological union was judged by bridging callus formation observed on at least 3 of 4 cortices in anteroposterior and lateral views., Results: Union was observed in 17 (94.4 %) patients of the autologous platelet group. The average time to union was 9.2 weeks (range 8 to 18 weeks) after percutaneous autologous platelet injection (P < 0.0517) .In the control group, union was observed in 14 (77.8 %) patients (P = 0.672). The average time to union following percutaneous bone marrow injection was 11.6 weeks (range 9 to 28 weeks). The proximal 1/3 shaft non union healed comparatively faster than the distal 1/3 shaft tibia (P ≤ 0.0612). No correlation was observed between the comminuted and non comminuted fracture non union (P = 0.789). A significant correlation was noted as regards the non union healing time duration in patients who were on insulin and oral hypoglycemic drugs (P ≤ 0.001) and also about the total duration of diabetes mellitus in years (P ≤ 0.003)., Conclusion: This investigation showed that percutaneous autologous platelet gel delivery is sufficient method to obtain union in diabetic tibial fracture non unions, which is less invasive procedure than bone marrow injection. The efficacy of this autologous platelets is once again well established and this study reinforced categorically the previously published report by the author., Competing Interests: Declaration of competing interest None., (Copyright © 2024 Elsevier Ltd.

- Abstract
The purpose of the study was to investigate whether arthroscopic treatment of carpal scaphoid nonunions by osteosynthesis with bone grafting represents a successful surgical technique. This systematic literature review, conducted following the PRISMA guidelines, explores the past 10 years of clinical studies concerning the arthroscopic treatment of scaphoid nonunions. The most relevant keywords were used to search the databases, and the Downs and Black 27-item checklist has been used as quality assessment tool. Twelve papers that meet the premised eligibility criteria have been identified. These studies demonstrate the efficacy of this surgical solution, achieving a postoperative union rate of 96% in the average time of 13.5 weeks. Regardless of the method of synthesis and the origin of the graft used, excellent results were obtained. Patients who underwent this procedure reported a pain reduction of almost 80% compared to the preoperative level, improvement in grip strength close to 40%, and recovery in wrist function during daily activities. Arthroscopy has numerous advantages compared to the open approach. These are technically recognized by the surgeon and by the patient. Some disadvantages include a longer intraoperative time and considerable significant technical difficulty. Arthroscopic treatment of scaphoid nonunion by osteosynthesis with bone graft achieves a 96% union rate of the treated scaphoid with satisfying clinical results., (© 2024. The Author(s).)

- Abstract
Objectives: To assess trends in Patient-Reported Outcome Measurement Information Systems (PROMIS) Physical Function (PF) and Pain Interference (PI) in surgically treated tibial shaft fracture patients progressing to union versus nonunion., Design: Retrospective cohort study., Setting: Level 1 trauma center., Patient Selection Criteria: Patients with operatively treated tibial shaft fractures (AO/OTA 42-A, B, C) using an intramedullary nail., Outcome Measures and Comparisons: PROMIS PF and PI were compared between patients progressing to union and patients requiring nonunion repair., Results: A total of 234 patients (196 union, 38 nonunion) were included consisting 144 men and 90 women. The mean age of included patients was 40.8 years. A significant difference in mean PROMIS PF between union and nonunion patients was observed at 1-3 months ( P = 0.005), 3-6 months ( P < 0.001), 6-9 months ( P = 0.003), and 6-12 months ( P = 0.018). The odds of developing nonunion for every unit decrease in PROMIS PF was significant at 3-6 months (OR 1.07, P = 0.028) and 6-9 months (OR 1.17, P = 0.015). A significant difference in mean PROMIS PI between union and nonunion patients was observed at 1-3 months ( P = 0.001), 3-6 months ( P = 0.005), and 6-9 months ( P = 0.005). The odds of developing nonunion for every unit increase in PROMIS PI was significant at 1-3 months (OR 1.11, P = 0.005), 3-6 months (OR 1.10, P = 0.011), and 6-9 months (OR 1.23, P = 0.011)., Conclusions: Poorly trending PROMIS PF and PI in the clinical setting is a factor that can be used to evaluate progression to nonunion following tibial shaft repair where imaging studies may lag behind., Level of Evidence: Prognostic Level III.

- Abstract
Background: Reconstructive microsurgery techniques using vascularized bone grafts have revolutionized the treatment of complex cases associated with recalcitrant non-unions or osteomyelitis. The medial femoral corticoperiosteal flap (MFCP flap) has emerged as a valuable option in bone reconstruction. Its clinical applications have been extended over the years considering this flap from non-unions with minimal bone lost, up to large intercalary defects of the upper and lower extremities. This article aims to present the clinical applications and outcomes of the MFCP flap in various reconstructive scenarios., Methods: Seventy-nine patients with persistent non-union and bone defects of the upper and lower limb were evaluated from June 2008 to October 2020. All of them were reconstructed with a corticoperiosteal flap from the medial femoral condyle in our hospital. Previous procedures, bone gap and type of flap used were recorded. Postoperative functional status was assessed with time of bone healing, complications and clinical final outcome., Results: Radiological evidence of bone union was observed at 4.09 months (range 2-9). Healing rate was 97% with periosteal corticocancellous flaps (PCC flaps) and 93% with corticoperiosteal flaps (CP flaps). Average follow-up was 14.5 months (range 5-28). There were no significant donor site complications., Conclusions: The MFCP flap offers a versatile and reliable option for bone reconstruction. Its ability to provide vascularized bone tissue with low morbidity enhances the healing process and improves outcomes. The MFCP flap has been increasing its applications and it serves as a valuable option in the treatment of recalcitrant non-unions or bony defects irrespective of site and size up to 5 cm in the upper and lower extremities., (© 2024.

- Abstract
Background: Talar neck non-unions result in significant hindfoot deformity and morbidity and are infrequently reported in the literature. The optimal surgical management for this condition is evolving, with various authors reporting the results of open reduction and internal fixation (ORIF) with bone grafting (BG), ankle fusion and modified Blair fusion. We performed this study to report the clinical and radiological outcomes of a cohort of talar neck non-unions managed by ankle joint preserving reconstruction., Methods: This was an ambispective study which included 8 patients (7 male and 1 female) with talar neck non-unions. All patients underwent ORIF+BG through dual approaches. Additional medial malleolar osteotomy was done in 2 cases, and calcaneofibular split approach to the subtalar joint in 3. Adjunct subtalar fusion was done in 5 cases. Clinical and radiological evaluation was performed pre- and post-operatively. Functional outcomes were assessed by the Manchester Oxford Foot Questionnaire (MOxFQ)., Results: The mean age of patients 32.3 ± 13.1 years. The mean surgical delay was 4.1 ± 1.7 months. As per Zwipp and Rammelt classification of post-traumatic talar deformities, 5 cases were classified as Type 3, 2 were Type 4, and 1 was Type 1. Union was achieved in 7 cases at a mean of 3.4 ± 1.3 months. One case had progressive collapse, which was managed by pantalar arthrodesis. All 3 cases where subtalar fusion was not performed primarily demonstrated subtalar arthrosis, but none required a secondary subtalar fusion. The MOxFQ score from 61.1 ± 10.1 to 41 ± 14.1 postoperatively (P = 0.005). The mean follow-up was 14.6 ± 6.8 months., Conclusion: ORIF+BG of the talar neck, with or without subtalar fusion has the potential to achieve solid union, correct the hindfoot deformity and improve functional outcomes. However, larger studies with longer follow-up are needed to evaluate the long-term efficacy of this procedure., Competing Interests: Declaration of competing interest The authors have no declarations and no conflicts of interest., (Copyright © 2024 Elsevier Ltd.

- Abstract
We report the treatment of two patient with humeral fractures with one or more risk factors for nonunion. The first patient was elderly with a previously diagnosed central nervous sys-tem injury. The second elderly patient previously sustained a cerebral vascular accident affecting the fractured arm. The fracture was oblique in the proximal third of the humerus. We achieved bone healing non-operatively utilizing a spe-cialized plastic orthosis that included a deforming element made of dense foam. This device asymmetrically increases the soft tissue pressure around the fracture.

- Abstract
Treatment of mid-shaft fractures of both forearm bones in adults typically consists of individual plate fixation of each bone according to AO principles. The primary objective of this multicentre retrospective study was to identify predictive and prognostic factors of failed bone union after internal fixation with a standard plate in adults. 130 mid-shaft fractures of both forearms occurred in 92 men and 38 women, who had a mean age of 35.1 years were reviewed; 42 were open: 31 were Gustilo type I, 10 were type II and 1 was type III. All patients underwent ORIF using a direct approach over the supinator crest for the ulnar fracture and using an anterior approach at the level of the radial fracture by dynamic compression plate in 90 cases and a limited-contact dynamic compression plate in 40 cases, all with 3.5 mm diameter screws. The radiographs from all patients were reviewed after a minimum follow-up of 12 months: primary union of both forearm bones occurred in 121 of the 130 cases after a mean of 4.6 months (±2.6). 104 patients were reviewed clinically with a minimum follow-up of 12 months and a mean of 36 months (±21.7). According to Tscherne-Oestern classification, 79 % of patients had a very good outcome, 6 % had a good outcome, 10 % had a fair outcome and 5 % had a poor outcome Non-union occurred in 9 patients (one septic): 4 times at both fracture sites, 4 times at the ulna only and once at the radius only. The mean age was higher in the patients with non-union: 46.4 years versus 34.2 (P = 0.08). Smoking, alcoholism, associated head trauma, presence of pre-operative nerve deficit and open fracture did not appear to be risk factors for non-union. The type of plate used and the number of screws placed on either side of the fracture site had no effect on union. This patient series had a similar non-union rate to the one reported in other published studies, likely because the technical rules were followed. A lack of statistical power probably prevented us from identifying prognostic factors for bone union., Competing Interests: Declaration of competing interest The authors have declared no conflict of interest., (Copyright © 2024 Elsevier Ltd.

- Abstract
Purpose: The medial femoral trochlea flap has been described as a method of scaphoid proximal pole nonunion reconstruction when the proximal pole is deemed nonsalvageable. The lateral femoral trochlea (LFT) is an alternative donor site providing a comparable vascularized convex osteochondral flap. We describe the technique and outcomes of our first 17 cases of LFT flap reconstruction of the proximal scaphoid pole with a minimum follow-up of 14 months., Methods: Seventeen of the first 24 patients who underwent LFT scaphoid reconstruction at 3 institutions were able to be contacted for clinical follow-up and chart reviews. We recorded patient age and sex, duration of nonunion, number of previous surgical procedures, details of surgical technique, achievement of osseous union, complications, additional postoperative procedures, preoperative and postoperative pain, and range of motion. Preoperative and postoperative scapholunate and radiolunate angles were analyzed on x-rays and achievement of osseous union on computerized tomography scans., Results: The average age of patients included was 35 years (range, 16-55 years). Follow-up data were recorded at an average of 33 months (range, 14-62 months). Ten patients had previous procedures (average, 1; range, 0-2). Median duration from trauma to LFT was 3.4 years (range, 8 months-12 years) among patients who had a recognized date of injury. Osseous healing was achieved in 16 of 17 patients and confirmed by computerized tomograpy scan. Twelve patients reported complete pain relief, while 5 reported partial pain relief. Final postoperative range of motion was 59°extension (range, 30°-85°) and 50° flexion (range, 10°-80°), which was comparable to preoperative values. Preoperative (59°) and postoperative (55°) scapholunate angles were similar to normal wrists., Conclusion: Vascularized LFT flaps provide an alternative donor site for vascularized osteochondral reconstruction of proximal pole scaphoid nonunion. Rate of union, range of motion, and pain relief are similar to reported results with medial femoral trochlea flap reconstruction., Type of Study/level of Evidence: Therapeutic IV., (Copyright © 2024 American Society for Surgery of the Hand.

- Abstract
Introduction: Infected tibial non-unions with associated bone loss can be challenging to manage. At present, the two main methods utilized in the management of these fractures include the Ilizarov technique of Distraction Osteogenesis (DO) using external fixator devices, or alternatively, the Induced Membrane Technique (IMT), devised by Masquelet. As there is a paucity of data directly comparing the outcomes of these techniques, there is no universal agreement on which strategy a surgeon should choose to use., Aims: This systematic review and meta-analysis aimed to summarize the outcomes of both DO and IMT, in terms of primary outcomes (bone union and infection elimination), and secondary outcomes (complication rates and functional outcomes)., Methods: A PRISMA strategy was used. Medline, Web of Science, Cochrane Central Register of Controlled Trials (CENTRAL), and Google Scholar library databases were interrogated using pre-defined MeSH terms and Boolean operators. Quality of evidence was evaluated using OCEBM and GRADE systems., Results: Thirty-two studies with 1136 subjects met the inclusion criteria. With respect to the primary outcomes of interest, union was observed in 94.6% (DO method) and 88.0% (IMT method); this difference, however, was not significant between the two techniques (p = 0.45). In addition, infection elimination rates were also higher in the Ilizarov DO group when compared to Masquelet (Mq) IMT (93.0% vs 80.4% respectively). Again, no significant difference was observed (p = 0.06). For all secondary outcomes assessed (unplanned re-operations, re-fracture rates amputation rate), no statistically significant differences were documented between the treatment options., Conclusion: This study demonstrated that there is no clinical difference in outcomes for patients treated with Ilizarov DO versus Mq IMT techniques. The evidence base at present is relatively sparse and, therefore, we would recommend for further Level I studies to be conducted, to make more meaningful conclusions., (© 2023. The Author(s).)

- Abstract
Background: Psychiatric comorbidities have been shown to influence outcomes of various orthopedic pathologies. This study aimed to compare rates of delayed scaphoid union and surgical intervention for fractures in patients with and without comorbid psychiatric diagnoses., Methods: A matched retrospective cohort study was performed using the PearlDiver database to determine the association of depression, anxiety, bipolar disorder, and schizophrenia with delayed union rates within 3 and 6 months and rates of nonacute surgical intervention (fixation or grafting) within 6 and 12 months of scaphoid fracture. Analyses were completed using multivariate logistic regression., Results: Among 20 340 patients, a comorbid psychiatric diagnosis was associated with increased rates of delayed scaphoid union at 3 months (odds ratio [OR] = 1.29; 95% confidence interval [CI], 1.14-1.45) and 6 months (OR = 1.23; 95% CI, 1.10-1.38). At 3 months, women with any psychiatric disorder (OR = 1.58; 1.29-1.66), depression (OR = 1.68; 1.31-2.17), and schizophrenia (OR = 5.32; 95% CI, 1.06-26.79) were more likely to experience delayed union, with similar results at 6 months. Men with bipolar disorder experienced increased delayed union rates at 6 months (OR = 1.40; 1.03-1.91). A comorbid psychiatric diagnosis (OR = 1.10; 1.01-1.20) was associated with increased rates of surgical intervention, whereas schizophrenia was associated with decreased rates (OR = 0.58; 0.34-0.99)., Conclusion: Patients with comorbid psychiatric conditions experienced increased rates of delayed scaphoid union. These results underscore the importance of understanding factors that may place patients at risk of impaired recovery., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: JAA, ER, KC, EJT, and JAK do not report any disclosures.

- Abstract
BACKGROUND Scaphoid nonunion (SN) is a challenging condition in wrist pathology, often resulting in severe consequences if left untreated. Surgical intervention, particularly using vascularized bone grafts (VBGs), is a promising but uncertain approach. The 4+5 extensor compartment artery (ECA) pedicled graft, less commonly used for SN, has potential benefits due to its vascular supply and accessibility to the scaphoid. This study aimed to evaluate the effectiveness of the 4+5 ECA pedicled graft combined with headless compression screw fixation in treating avascular necrosis (AVN)-induced proximal pole SN. Radiological results, functional outcomes, and complications related to this method were assessed. MATERIAL AND METHODS This was a retrospective analysis of 19 proximal pole SN cases with AVN treated using the 4+5 ECA-VBG technique from 2016 to 2022. Patients underwent preoperative evaluation and postoperative follow-up for at least 1 year. Data on surgery, demographics, radiological assessments, and functional outcomes were recorded and analyzed statistically. RESULTS All patients achieved radiographic union within 8.5 weeks postoperatively, with revascularization of proximal pole necrosis. Significant improvements in functional outcomes were observed, including pain reduction, increased wrist range of motion, improved grip and pinch strength, and enhanced wrist scores. No major complications were reported. CONCLUSIONS The 4+5 ECA-VBG technique, with headless compression screw fixation, showed high success rates in treating AVN-induced proximal pole SN. This method offers comprehensive restoration of wrist function and minimal complications, making it a viable option for SN management, especially in AVN cases. Further research is needed to confirm these results and establish standardized protocols for SN treatment.

- Abstract
Background: Fractures with large bone defects and non-unions are a great challenge for veterinary orthopaedists. In small dog breeds, this complication is commonly encountered in fractures of the radius and ulna due to poorer vascularisation of the distal antebrachium region., Case Description: A case of radius/ulnar non-union in a 1.5-year-old Pinscher occurring after trauma and two successive unsuccessful osteosyntheses is described. During the operative revision, after the removal of existing bone implants, the bone defect was filled with cortical autologous bone graft. Autocancellous bone mixed with erythropoietin was applied proximally and distally to the cortical autograft for stimulation of bone healing. The post-operative period was without complications. As early as the 9th post-operative week, the animal was able to bear weight on the limb, without signs of lameness, pain, and swelling. Radiologically, a very good bridging of the graft was observed. Fifteen weeks after the operative revision, the fracture was completely healed with excellent clinical outcome., Conclusion: The application of autogenous cortical bone graft and cancellous autograft mixed with erythropoietin demonstrated an excellent therapeutic effect and resulted in complete regeneration of the large bone defect over a 15-week period., Competing Interests: The authors declare no conflict of interest.

- Abstract
Injury to the tarsometatarsal joint (TMT) results in instability throughout the midfoot that does not often improve with conservative management. If instability is identified, surgical intervention is frequently recommended, either open reduction and internal fixation (ORIF) or primary arthrodesis (PA). These 2 treatment options have been compared in the literature multiple times, often reporting similar outcomes. Due to this, as well as the need for subsequent hardware removal after ORIF has led many surgeons towards PA at the index surgery. Concern for nonunion is a leading concern with surgeons who advocate instead for ORIF. The purpose of this study is to review patients who underwent PA and observe nonunion rates. Nonunion at the TMT has been previously studied, but only in the chronic setting. We performed a retrospective study of 34 patients who had PA in the management of an acute Lisfranc injury. The average age in our study was 43.9 years old (range 19-72, SD 17.4) with an average follow-up of 9.4 months (range 4-33, SD 6.2). Radiographs were evaluated for signs of nonunion at regular postoperative intervals. Within the patients included in the study, a total of 71 TMT joints were fused. Overall successful fusion rate was 95.8% at an average of 7.9 weeks (range 6-12, SD 1.4) postoperatively. Individual nonunion rates at the first, second, and third TMT were 0%, 1.4% and 2.8% respectively. Our study demonstrates that primary arthrodesis provides a predictable outcome with low nonunion rates in the management of acute Lisfranc injury., (Copyright © 2024 the American College of Foot and Ankle Surgeons.

- Abstract
This pragmatic randomized controlled trial compared lunocapitate fusion (LCF) and four-corner fusion (4CF) for scapholunate advanced collapse (SLAC) and scaphoid nonunion advanced collapse (SNAC) in 64 patients. The primary outcome was change in grip strength from preoperative to 1 year postoperatively. The secondary outcomes were Disability of the Hand, Arm, and Shoulder score, Patient Rated Wrist Evaluation score, EuroQol-5D-3L, range of motion, key pinch strength and complications 12 months postoperatively. Grip strength improved only to a small extent and there was no difference between the groups. No differences were found in the secondary outcomes. In conclusion, LCF is not inferior to 4CF regarding strength, range of motion or patient-reported outcome measures.

- Abstract
Background: Femoral and tibial fractures may result in delayed union and nonunion, posing significant challenges in orthopedic practice. The Ilizarov technique has emerged as a promising solution for managing these complex cases., Objectives: Evaluate the radiographic and functional results of Ilizarov fixation in the treatment of nonunion of tibia and femur fractures., Design: Retrospective., Settings: Hospitals affiliated with a university hospital., Patients and Methods: Patient demographics, fracture characteristics, and treatment details were analyzed for the period from October 2015 to September 2022 in patients who were treated for nonunion of the tibia and femur using the Ilizarov fixator. Clinical and radiological assessments were performed using the Association for the Study and Application of Methods of Ilizarov (ASAMI) criteria. The study focused on assessing the average duration for union and frame removal, bone results, successful union rates, and functional results using the ASAMI criteria, obtaining data from the existing medical records, spanning various medical facilities treating nonunion fractures., Sample Size: 126 patients., Results: The average duration for union and frame removal was 8 months, with excellent bone results observed in 60.32% of cases. Out of 126 patients, 118 achieved successful union, while there were 2 failure cases necessitating amputation (1.52%). Functional results revealed excellent outcomes in 39.68% of cases. Complications included pin tract infections, ankle and knee stiffness, and limb shortening. External fixation duration and infection eradication were consistent with previous research, emphasizing the technique's effectiveness., Conclusions: The Ilizarov technique proved highly effective in managing nonunion tibia and femur fractures, offering favorable outcomes in terms of union, infection control, pain relief, and functional recovery. While excellent bone outcomes do not guarantee optimal function, this method remains a reliable approach for complex cases., Limitations: Potential biases inherent in retrospective analyses and the need for further randomized controlled trials to comprehensively compare treatment modalities.

- Abstract
Objective: This work aimed to evaluate the results of using a 2-stage surgical treatment strategy without doing anterior transposition of the ulnar nerve (ATUN) for cases with long-standing nonunited fracture lateral humeral condyle (LHC) in children, accompanied by a critical review., Methods: A consecutive 12 children with a long-standing ">2 years" nonunited LHC with evident radiologic gross anatomic distortion of the elbow were included in this study. A 2-stage surgical treatment strategy was applied, wherein the first stage, open functional reduction, osteosynthesis, and iliac bone graft were done. Then after 6 months, the second stage surgery was carried out in the form of supracondylar humeral corrective osteotomy if the cubitus valgus angle was ≥20 degrees. ATUN was not done for any of the cases even with those having ulnar nerve dysfunction., Results: Union took place in 11 out of the 12 cases after a mean follow-up period of 11 weeks (range: 8 to 14 wk; SD: 1.6). All the 7 cases showed preoperative ulnar nerve dysfunction and reported clinical recovery at the end of their follow-up., Conclusions: Two-stage surgical treatment strategy without ATUN is a convenient, reproducible, and successful line of treatment for children presented with longstanding nonunited LHC with anatomically distorted elbow., Level of Evidence: Level IV-case series., Competing Interests: The author declares no conflicts of interest., (Copyright © 2024 Wolters Kluwer Health, Inc.

- Abstract
Introduction: Rib fractures commonly occur in trauma patients with varying presentations. Though the literature in recent years has moved toward favoring more early intervention of acute rib fractures, little has been reported on the matter of surgical fixation for symptomatic rib fracture nonunions., Materials and Methods: We performed a review of PubMed and Cochrane databases for articles published since 2000. Inclusion criteria were studies with greater than six months of follow-up, while case studies were excluded. A thorough analysis was performed on patient outcomes, complications reported, operative techniques utilized, and fixation systems used, among other parameters reported by the articles., Results: One hundred and thirty-nine studies resulted from our review, and a total of nine studies met our inclusion criteria with a combined total of 182 patients who underwent open reduction and internal fixation for symptomatic rib fracture nonunions. All studies reported a significant reduction of pain with increased satisfaction in the majority of patients. There were a total of 71 postoperative complications, the most common of which included surgical site infections, hardware failure, and hematoma. The most serious complications were insulting injury to the lung parenchyma or pleura; however, these were extremely rare based off the current literature. The use of bone grafting was common with eight of the nine studies mentioning the benefits of grafting., Conclusion: Surgical stabilization of rib fracture nonunions appears to be an appropriate treatment alternative, and various techniques and approaches may be used with similar success. Further studies with higher level of evidence are recommended on the subject., (© 2024. The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.)

- Abstract
Objectives: Treatment of 5th metatarsal fractures via direct discharge from virtual fracture clinic (VFC) has become common practice in the NHS. We aim to assess the functional outcome and incidence of non-union in a series of 5th metatarsal base fractures, exposed to 1-year of follow-up., Methods: 194 patients who sustained a fracture between the period February 2019 to April 2020 were included, referred via the VFC pathway. Radiographs were reviewed to classify in which zone, the fracture occurred along with union on subsequent follow-up. Telephone follow-up was used to measure patient functional outcomes (EQ-5D & FAAM survey) and satisfaction with the VFC service., Results: Off 194 patients, 53 (27.3%) had zone 1, 99 (51%) had zone 2, and 42 (21.6%) had zone 3 fractures. 80 were discharged directly from VFC, with 114 patients being offered at least one face to face clinic follow-up. Six (3.1%) patients had clinical and radiological evidence of non-union; 4 in zone 2, and 2 in zone 3. No zone 1 injuries were identified as a non-union. Only 2 patients had surgery, 1 of which was for symptomatic non-union. Of the 6 non-union patients, 1 had surgery, 4 did not wish to have surgery and the final non-union patient was deemed unsuitable for surgery., Conclusion: The VFC is an effective way of managing 5th metatarsal fractures, with high patient satisfaction. Conservative management has excellent outcomes, with a low percentage of zone 2 and 3 injuries developing a symptomatic non-union. Functional outcome surveys provide further reassurance., (© 2024.

- Abstract
The aim of this retrospective study was to assess the relation between carpal malalignment correction and radiological union rates in surgery for scaphoid nonunions. A total of 59 scaphoid waist fracture nonunions treated with open reduction and palmar tricortical autograft were divided according to their pre- and postoperative scapholunate (SL) and radiolunate (RL) angles. We found that carpal malalignment failed to correct in 32 of 59 (54.2%) patients despite meticulous surgical technique and placement of an appropriately sized wedge-shaped graft. In total, 43 (72.9%) fractures united at a mean of 4.47 months (range 3-11). Of the 27 fractures with postoperative SL and RL angles within the normal range, 21 united, whereas 22 of the 32 remaining fractures that failed to achieve postoperative angles within the normal range went on to union. The postoperative SL and RL angles were not related to union. Our findings suggest that in scaphoid fracture nonunion surgery, carpal malalignment may not be corrected in a substantial proportion of patients, but such correction may not be essential for bony union. Our findings also show that there is no marked collapse of the scaphoid graft in the early postoperative period., Level of Evidence: IV., Competing Interests: Declaration of conflicting interestsThe authors declare no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

- Abstract
Introduction: The overall frequency of proximal femoral fractures means that we are repeatedly confronted with failed healing and implant failure, despite a relatively low nonunion rate especially in intertrochanteric fractures (< 5%). The aim of this paper is to present our approach to treating these nonunions of the proximal femur and discuss the treatment results., Material and Methods: Between 2009 and 2023, patients with nonunion of the proximal femur were retrospectively identified and analyzed. Age, gender, time to revision, the Weber-Cech classification of pseudarthrosis and radiographic imaging before and after revision were analyzed., Results: A total of 66 patients were analyzed. The mean age was 58 years (range 25-88 years). The overall healing rate was 88% with a mean consolidation time of 8 months (range 2-29 months). The main osteosynthesis procedures were plate osteosynthesis (n = 45, of which 44 were blade plates), and nail replacement (n = 12). Other procedures included augmentative plate osteosyntheses (n = 4), isolated cancellous bone graft (n = 2), nail dynamization (n = 2), and the use of a dynamic hip screw (n = 1)., Discussion: The analysis of our treatment data as well as the current literature, revealed a trend towards intramedullary revision procedures. Implants that can be used to correct the CCD angle, such as the blade plate, remain a predictable option to achieve correction, especially in nonunions with an increased degree of varus. Particularly in the subtrochanteric region, fractures can also be treated in a targeted manner by a combination of mechanical and biological methods with a reamed nail change to a larger caliber implant., (© 2024.

- Abstract
Purpose: Re-revision of subtrochanteric non-unions is technically challenging and lacks robust evidence. The results of managing subtrochanteric fractures after multiple failed procedures have rarely been reported in the literature. This study aims to evaluate the effect of valgus reduction on non-united subtrochanteric fractures with single or multiple failed revision surgeries., Methods: Twenty-six patients with aseptic subtrochanteric fracture non-union underwent failed single or multiple revision procedures after index fracture fixation surgery between 2011 and 2019. The exclusion criteria were as follows: septic non-union, peri-prosthetic, and pathological fractures. Lateral-based wedge valgus reduction and compression at the non-union site using a valgus-contoured DCS together with decortication, debridement, and bone grafting were used. The main outcome measurement was radiological union, pain, LLD, HHS, and restoration of pre-fracture activities., Results: The mean follow-up was 4.5 years (range 3 to 7); prior revision surgeries range from two to five and union at 6.5 months (range 3 to 10) and the delayed union in one case and an infected non-union in one case. The mean LLD was 4 cm (range 3 to 5), which improved to 1.5 cm (range 1 to 4) (P-value < 0.001). The mean VAS was 7 (range 6 to 8), and 24 patients achieved painless ambulation without a walking aid after the union. The mean HHS was 40 (range 25 to 65), which improved to 85 (range 55 to 95) (P-value < 001), achieving 15 excellent, ten good, and one poor results., Conclusion: Mechanical optimisation by lateral closing wedge and stable fixation with pre-contoured DCS with biological enhancement resulted in a successful outcome in recalcitrant subtrochanteric non-unions., (© 2024.
