Large posterolateral tibial fragments, known as Volkmann fractures, are common in ankle fracture-dislocations and typically require open reduction and fixation with interfragmentary screws and often buttress plates using a prone posterolateral approach. In this setting, fibula plating often necessitates dissection of the lateral window between the peroneal tendons and the skin, increasing wound-related complications. In recent years, intramedullary nailing of fibula fractures has gained popularity as a minimally invasive technique that allows load-sharing stabilization. However, this procedure has traditionally been performed in the supine position, which can pose challenges if a Volkmann-type fracture is present, requiring repositioning and losing access to the fibula through the posterolateral approach. Our objective is to describe a technique for fixing ankle fracture-dislocations with large posterolateral fragments using tibial buttress plates and fibula nails through a prone posterolateral approach without dissecting the lateral window. Additionally, we will present a case series with preliminary results., 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 Elsevier Ltd.

Volar proximal interphalangeal joint fracture-dislocations are rare injuries. Treatment is challenging when they are not identified acutely, with poor outcomes reported. We report a surgical technique to treat chronic volar proximal interphalangeal joint fracture-dislocations: a reverse hemi-hamate autograft., (Copyright © 2023. Published by Elsevier Inc.)

Purpose: Several improvised dynamic external fixation devices are used for treating unstable dorsal proximal interphalangeal (PIP) joint fracture-dislocations. We compared the effectiveness of 3 constructs for simulated dorsal PIP joint fracture-dislocations in a cadaver model., Methods: We tested 30 digits from 10 fresh-frozen, thawed cadaver hands. We aimed to remove the palmar 50% of the base of each digit's middle phalanx (P2), simulating an unstable dorsal PIP joint fracture-dislocation. Each PIP joint was then stabilized via external fixation with either a pins-and-rubber-bands construct, pins-only construct, or tuberculin syringe-pins construct. We allocated 10 digits per fixation group. The finger tendons were secured to a computer-controlled stepper motor-driven linear actuator. Via this mechanism, all PIP joints were taken through 1,400 cycles of flexion-extension. With the PIP joint in neutral extension, we measured the P2 dorsal translation at baseline, after fixator stabilization, and after the motion protocol., Results: The actual mean P2 palmar defect created was 48% of the base. All PIP joints were unstable after creating the defect, with a mean initial P2 dorsal displacement of 3.7 mm. After application of the fixators, all PIP joint dislocations were reduced. The median residual P2 dorsal displacements were 0.0 mm for the pins-rubber bands group, 0.1 mm for the pins-only group, and 0.5 mm for the syringe-pins group. There were no cases of PIP joint redislocation after flexion-extension cycling, and the median dorsal P2 displacements were 0.0 mm for the pins-rubber bands group; 0.0 mm for the pins-only group; and 0.5 mm for the syringe-pins group., Conclusions: All 3 external fixators restored PIP joint stability following simulated dorsal fracture-dislocation, with all reductions maintained after motion testing. The syringe-pins construct had significantly greater median residual P2 dorsal displacement after the initial reduction and motion testing, which is of unclear clinical importance., Clinical Relevance: This study informs surgeon decision-making when considering dynamic external fixator options for dorsal PIP joint fracture-dislocations., (Copyright © 2023 American Society for Surgery of the Hand.

Purpose: Comminuted intra-articular fractures and fracture dislocations of the metacarpophalangeal (MCP) and interphalangeal joints are challenging. Dynamic external fixation, permitting early joint motion while still minimizing forces across the healing joint, can result in acceptable postoperative active range of motion (AROM). However, some fractures are not initially stable enough for early dynamic motion; further, many available dynamic external fixation systems are costly and cumbersome. We reviewed our experience using an external fixator made from a 1-mL syringe and K-wires and report outcomes using it as a static fixator, dynamic fixator, or configured as a static fixator and then converted to a dynamic fixator in the clinic., Methods: Patients with intra-articular fractures and fracture dislocations of the MCP and proximal interphalangeal (PIP) joints treated between 2014 and 2020 using syringe external fixators were retrospectively reviewed. We reviewed demographics, mechanisms, treatment types and durations, and postoperative AROM, as well as complications including infection, pin loosening, nonunion, hardware failure, and need for further surgery. Patients were analyzed by the level of joint injury (MCP versus PIP) and by treatment pattern., Results: After excluding 23 patients with 25 joint injuries who were lost to follow-up or had inadequate outcome data, 27 patients with 29 joint injuries were reviewed. The average follow-up was 171 days after surgery. The postoperative AROM at the MCP level averaged 55° for static fixation and 30° for static-to-dynamic fixation. The postoperative AROM at the PIP level averaged 64° for static fixation, 66° for static-to-dynamic fixation, and 80° for dynamic fixation. Three pin site infections and 2 loose pins were reported., Conclusions: The syringe external fixator is an inexpensive, effective, and customizable treatment for intra-articular MCP and interphalangeal fractures and fracture dislocations, and results in acceptable postoperative AROM outcomes and complication rates., Type of Study/level of Evidence: Therapeutic IV., (Copyright © 2022 American Society for Surgery of the Hand.

Purpose: To assess the use of a 2-mm miniplate as a dorsal blocking plate to stabilize the central avulsion fragment in a proximal interphalangeal joint (PIP) volar fracture dislocation., Methods: This was a case series comprising 8 patients with volar fracture dislocation of the PIP joint. The average age of the patients was 36 years. The patients were managed by this technique within an average of 11 days following the injury. The clinical outcome measurements included the assessment of pain and range of motion of the PIP and distal interphalangeal joints., Results: The average follow-up duration was 20 months. The mean visual analog scale pain score was 1.9. The average range of motion of the PIP joint was 82°, whereas the average range of motion of the distal interphalangeal joint was 43°. Reduction of the subluxation was achieved in all cases, with no articular step remaining., Conclusions: A dorsal blocking plate is a simple technique, associated with a satisfactory outcome, for volar fracture dislocation injuries of the PIP joint., Type of Study/level of Evidence: Therapeutic V., (Copyright © 2022 American Society for Surgery of the Hand.

Introduction: Injuries involving the tarsometatarsal (TMT) joint are relatively uncommon, and the surgical treatment is potentially characterized by a high complications rate. The purpose of this study is to evaluate the results of the treatment of Lisfranc fracture-dislocations treated with closed reduction and percutaneous fixation with K-wires, considering complications and re-intervantion rate., Materials and Methods: A retrospective review was performed on all patients undergone closed reduction and percutaneous fixation with K-wires of a Lisfranc fracture-dislocation. Patients have been clinically evaluated at last follow up by American Orthopaedic Foot and Ankle Society (AOFAS) midfoot score and Visual Analogue Scale (VAS), as well as by radiograph assessment., Results: Following inclusion and exclusion criteria, 15 patients have been included, with a mean age of 48.2 ± 5.6 years. Average follow-up was 3.8 ± 1.8 years (range 1-6). 7 fractures analyzed were classified as type A, 7 as type B (3 were B1, 4 were B2) and 1 as type C1. No case of loss of reduction has been observed at radiographic 1-month follow-up. At last follow-up mean AOFAS midfoot score and VAS score were respectively 82.2 ± 10.4 and 1.5 ± 1.3. Registered complications showed one deep vein thrombosis and 2 cases of complex regional pain syndrome (CRPS). One patient subsequently underwent arthrodesis of the tarsometatarsal joint for post-traumatic arthritis., Conclusions: The treatment of the fracture-dislocations of the Lisfranc joint by percutaneous reduction and fixation with K-wire can achieve good clinical outcomes with a low rate of complications and reoperations., Level of Evidence: Level IV., Competing Interests: Declaration of Competing Interest The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (Copyright © 2020.

Posttraumatic acute carpal tunnel syndrome is a not a usual complication in traumatic hand injuries but requires more urgent and aggressive management. Compression of the median nerve should be systematically sought when there is a major and painful swelling of the hand, associated with one or several hand and wrist fractures. In rare case, a single metacarpal fracture or dislocation can be the only cause of median nerve compression and requires urgent diagnosis. If missed or neglected irreversible damage could occur to the median nerve. If surgery is perform in a timely manner outcomes are excellent, with complete recovery in most of the cases. We present the case of a 24-year-old man with an acute compression of the median nerve due to an intra-articular fracture of the 2nd metacarpal base. A bony fragment shifting from the base of 2nd metacarpal was found in the carpal tunnel participating, at least in part, in the compression of the median nerve., (Copyright © 2020 Elsevier Masson SAS.

Lisfranc injuries can be devastating to the athlete and nonathlete. In the athletic population, minor loss of midfoot stability compromises the high level of function demanded of the lower extremity. The most critical aspect of treatment is identifying the injury and severity of the ligamentous/articular damage. Not all athletes are able to return to their previous level of function. With appropriate treatment, a Lisfranc injury does not mandate the cessation of an athletic career. We focus on the diagnosis and an algorithmic approach to treatment in the athlete discussion the controversy of open reduction and internal fixation versus arthrodesis., Competing Interests: Disclosure Arthrex – Consultant, Speaker’s Bureau., (Copyright © 2020 Elsevier Inc.

This article is a brief overview of the elbow dislocations focusing on updates in treatment and rehabilitation protocols. The fight between obtaining elbow stability without leading to long-term elbow stiffness has been a continued focus in field of sports medicine.

Although finger joint dislocations are generally thought of as benign by many athletes and assumed to be a sprain, these injuries represent a spectrum that includes disabling fracture-dislocations. Failure to recognize certain dislocations or fracture-dislocations may result in permanent deformity and loss of motion. Simple dislocations are frequently amenable to early return to play with protection; however, more complex injuries may require specialized splinting or surgery. Delay in diagnosis of unstable proximal interphalangeal fracture-dislocations may require reconstruction or fusion. Early diagnosis and appropriate treatment are essential to ensure optimal functional results., Competing Interests: Disclosure The authors have no relevant interests to disclose., (Copyright © 2019 Elsevier Inc.

Carpal fractures of bones other than the scaphoid occur at a much lower rate than scaphoid fractures. The close relationship between the carpus, intrinsic and extrinsic wrist ligaments, and wrist kinematics makes a thorough history, clinical examination, and interpretation of imaging for carpal malalignment essential. Carpal malalignment should be addressed with reduction and fixation. Nondisplaced fractures are often treated nonoperatively and displaced intraarticular fractures are almost always treatment operatively. The physician should keep in mind the athlete's specific goals and needs. Treatment must be individualized. Options for early return to play should be discussed when possible., Competing Interests: Disclosure The authors have nothing to disclose., (Copyright © 2020 Elsevier Inc. All rights reserved.)

Background: Ankle fractures represents the third most frequent fracture in elderly patients. There is a current tendency to fix long bones fractures with locking plates. However, we rarely find published accounts about the use of locking plates in distal fibula fractures, except for biomechanical ones, studying human cadaveric fibula., Objectives: The main objective was to compare radiographic bone union rates at 6 and 12 weeks of follow up, then wound complications and hardware removal rates, and construct cost., Study Design & Methods: We retrospectively analyzed 105 patients who underwent surgery with locking plates or non-locking plates over a two-year period, out of which 42 patients were treated with non-locking plates (VIVES™ - Stryker Ⓡ ) and 63 with locking plates (VariAx™ - Stryker Ⓡ ,). We analyzed bone union on anterior posterior and lateral X-rays of the ankle. We collected data of wound complications and hardware removal from patient records. Multiple linear regression techniques were performed after identifying dependent variables., Results: There was no significant difference between non-locking and locking plates in the radiographic bone union rate of distal fibula, respectively at 6 and 12 post-operative weeks (85.71% vs. 81%; p = 0.525 and 97.62% vs. 96.83%; p = 1). No significant difference was found in the wound complication rate between the two groups (11.9% vs. 11.12%; p = 0.9). No significant differences were found in the hardware removal rate, either with or without operative site's infection (respectively: 30.95% vs. 39.68%; p = 0.361 and 21.42% vs. 38.09%; p = 0.071). Cost efficiency is in the favor of non-locking plates., Conclusion: Non-locking constructs are as effective as locking constructs in the treatment of displaced distal fibula fractures at a substantially lower cost. High-quality randomized controlled trials are needed in the future to verify the finding of this study., (Copyright © 2019 Elsevier Ltd. All rights reserved.)

Controversy exists for the optimum method of surgical treatment for the 'fitter' elderly patient with a displaced intracapsular fracture. 105 patients were randomised to treatment with either a cemented polished tapered stem hemiarthroplasty or a cemented total hip arthroplasty (THR) with a cemented acetabular cup. All patients were followed up for a minimum of one year using a blinded assessment of functional outcome. Those patients treated with a THR had a tendency to a longer hospital stay and increased medical (12 versus 62) and surgical complications (4 versus 2) in comparison to those treated by hemiarthroplasty. Mean operative times (842 versus 52 min) and operative blood loss (335mls versus 244mls) were increased for THR. Final outcome measures of residual pain and regain of function were similar for both methods of treatment. We recommend that caution should be exercised regarding the increased promotion of THR for intracapsular hip fractures until further studies are completed., (Copyright © 2019 Elsevier Ltd.

We report an unusual clinical presentation and surgical treatment of a Galeazzi-equivalent fracture in which initial closed treatment failed. This case was unique and challenging secondary to the formation of a neoulna volar to an unreduced periosteal sleeve injury, resulting in a bifid radiographic appearance., (Copyright © 2019 American Society for Surgery of the Hand.

Purpose: The purpose of this study was to determine the relationship between hemihamate graft size and proximal interphalangeal (PIP) joint flexion in a biomechanical fracture-dislocation model., Methods: We simulated middle finger PIP fracture-dislocations in 5 cadaver hands by resecting 50% of the palmar articular surface of the middle phalanx (P2) base. Fluoroscopy was used to confirm dorsal subluxation of the middle phalanx base after resection. A 10-mm osteochondral hamate graft was contoured to reconstruct the volar lip of the middle phalanx and was progressively downsized by 2-mm increments for each trial. A computer-controlled articulator and jig simulated active flexion and extension of the fingers. Maximum PIP flexion was measured at each graft size using fluoroscopy and digital imaging software. Clinically significant flexion block was defined as PIP flexion less than 90°., Results: The actual mean size of the volar defect created was 52% (3.5 mm) of the middle phalanx articular surface, which created instability and dorsal subluxation in all tested fingers. After hemihamate reconstruction, all specimens were stable throughout flexion and extension for all graft sizes. A flexion block of 90° occurred at a mean graft size of 191% of the defect (6.5 mm). With regard to the volar lip of the P2, grafts that projected an average 0.8 mm past the native volar lip position had 98° (range, 84°-107°) maximum PIP flexion. Grafts that projected an average of 3.1 mm past the native volar lip position had 90° (range, 69°-100°) maximum PIP flexion. Linear regression modeling incorporating all of the results predicted flexion block to occur at a graft size as small as 166% of the 50% volar P2 defect. In this model, for every 50% (1.7-mm) increase in graft size relative to the defect, PIP flexion decreased by approximately 6°., Conclusions: Nonanatomical hemihamate grafts produce a PIP flexion block at extreme sizes, predicted to occur at greater than 166% of a 50% P2 base articular defect in our model. This suggests that relatively large grafts can be used for reconstruction of PIP fracture-dislocations without substantial biomechanical block to PIP flexion. We suggest sizing no larger than 3 mm past the native P2 volar lip position to avoid an important mechanical block to PIP flexion., Clinical Relevance: The information from this study helps surgeons understand how large a hemihamate graft can be used for P2 volar base reconstruction before having a negative impact on PIP flexion., (Copyright © 2019 American Society for Surgery of the Hand.

Background: Resorbable osteosynthesis has been used in orthopaedic surgery for many years. However, indications for the use of these implants in the surgery of traumatic lesions of the foot have not yet been clearly defined. The aim of this study is to analyse reported experiences with the bioabsorbable devices and to suggest guidelines for their use in foot trauma surgery METHODS: We conducted a literature review to identify known indications for the use of absorbable devices in traumatic lesions of the foot. We also conducted a retrospective analysis of our registry, reviewing patients with traumatic lesions of the foot who were treated surgically with absorbable devices from November 2005 to January 2017. To this end, we analysed for each case the indication for the use of resorbable devices and the incidence of related complications., Results: Only 14 relevant studies were found. In the selected period, 76 patients were treated using bioabsorbable devices for a traumatic lesion of the foot. Nine patients were lost to follow-up or did not satisfy the inclusion criteria. Therefore, the final size of the registry was 67 patients. The average follow-up was 20.5 months (range 6-66). All the bioabsorbable devices used were screws and bars of poly-L-lactic acid (PLLA). The indications identified in the literature review and in our registry were osteosynthesis of small periarticular fragments in talus and calcaneus fractures, preliminary stabilisation of articular fragments in Sanders III calcaneal fractures and fracture-dislocations of the Lisfranc or Chopart joints. No foreign-body reactions occurred. However, in one case we registered a late mobilisation of a PLLA bar in a healed calcaneal fracture, probably as a consequence of surgical malpositioning of the device. All the operated lesions demonstrated a normal healing time, and the complication rate was comparable with those of other types of osteosynthesis., Conclusion: In foot trauma surgery the use of absorbable devices can give advantages. The most clearly defined indications are osteosynthesis of peri-articular or articular fragments in talus and calcaneus fractures, Sanders III calcaneal fractures and fracture-dislocations of Lisfranc's or Chopart's joints. Foreign-body reactions are rare and seem not to present a problem., (Copyright © 2019 Elsevier Ltd. All rights reserved.)

Purpose: Open reduction and internal fixation (ORIF) of Bennett fractures is increasingly preferred over closed reduction and percutaneous fixation (CRIF) in an attempt to prevent the development of post-traumatic arthrosis. The aim of this systematic review was to determine whether the preference for ORIF is justified based on the available literature regarding functional outcome and complications after surgery., Methods: A systematic review was performed in Medline, Embase, Cochrane CENTRAL, Web of science, and Google scholar. Duplicates were removed and title and abstract were screened after which full text articles were analysed. The reference lists of selected articles were screened for additional relevant studies. Study characteristics were recorded and methodological qualities were assessed after which data was extracted from the included articles. The Eaton-Littler score for post-traumatic arthrosis (primary outcome) on follow-up X-rays was used as primary outcome. Secondary outcomes were Grip strength, Pinch strength, persistent pain, fixation failure, functional impairment, infection and surgery time., Results: Ten studies were included; three retrospective comparative studies and seven retrospective case series. Of the 215 patients in these studies, 138 had been treated using an open technique and 77 by a closed percutaneous technique. The pooled rate of post-traumatic arthrosis was 57.5% (26.6-85.5) in the ORIF group versus 26.1% (3.9-59.0) in the CRIF group. Mean surgical operation time was 71.9 min for ORIF and 30.2 min for percutaneous patients. Fixation failure was significantly more often seen in the ORIF patients, 8.2% (0.7-22.8) vs. 2.9% (0.8-9.1), Risk Ratio 1.132 (0.01-176.745); p = 0.048. Infection was only seen in 5 CRIF patients. Persistent pain was seen in 32.9% (0.6-83.1) in ORIF patients versus 22.3% (8.1-41.1) in the CRIF patients. The pooled means Grip strength was 48.3 kg (95% CI; 39.7-56.9) versus 43.4 kg (95% CI; 22.9-63.8) for ORIF and CRPF, respectively. Functional impairment was similar between the two groups, 1.4% (0.1-4.4) vs 1.8% (0.1-5.7) respectively., Conclusion: The analysed data do not confirm ORIF to prevent post-traumatic arthrosis, secondly more fixation failure and pain was seen in the ORIF group. The pooled data show percutaneous fixation to be preferable over ORIF in the surgical treatment of Bennett fractures., (Copyright © 2019 Elsevier Ltd. All rights reserved.)

Background: Dynamic external fixation is a useful treatment option for unstable fracture-dislocations of the proximal interphalangeal (PIP) joint, because it simultaneously reduces axial pressure load on the joint surface, maintains congruent joint reduction, and permits early joint motion. However, most current devices are large, hindering finger movement, and unstable. To address these problems, we developed a dynamic external finger fixator, named the Micro Ortho Fixator ® . The purpose of this study was to review the results of using the new external finger fixator to treat unstable fracture-dislocations of the PIP joint., Materials and Methods: Nine patients who sustained unstable fracture-dislocation injuries of the PIP joint were treated with the Micro Ortho Fixator ® . Seven fractures were accompanied by depressed bony fragments at the base of the middle phalanx. All patients were evaluated for pain and range of PIP motion at the final follow-up. Radiographs of the affected fingers were evaluated for PIP congruity and reduction. The mean follow-up duration was 11.1 months (range: 6-33 months)., Results: At the final follow-up, pain averaged 0.3 (range: 0-2) on the Numeric Pain Rating Scale, and the total arc of motion at the PIP joint averaged 91.2° (range: 50-110°). All fractures had healed, and the intra-articular step-off improved from 1.9 mm (SD: 1.0) before surgery to 0.2 mm (SD: 0.4) at the final follow-up. The patients who sustained sports injuries returned to competition after an average of 3.5 months (range: 2.5-4 months)., Conclusion: The external fixator is compact and facilitates range-of-motion (ROM) exercises, has high stability, and achieves good joint congruity and an ROM equivalent to the healthy joint of the patient., Study Design/level of Evidence: Therapeutic/IV., (Copyright © 2018 The Japanese Orthopaedic Association.

Background: Lower cervical fracture-dislocations frequently occur with spinal cord injuries. There is no clear consensus on best treatment option. Anterior approach surgery with direct decompression and reduction has become widely accepted. We assessed clinical outcomes of anterior approach surgery in a retrospective cohort study., Methods: From January 2001 to January 2011, 312 patients with lower cervical spine fracture-dislocation with spinal cord injuries who were treated by the anterior approach were retrospectively analyzed. Of 312 patients, 218 (70%; 121 men and 97 women) met inclusion criteria. Clinical efficacy was evaluated using Odom's criteria and statistical analysis based on Cobb angle of kyphosis and Neck Disability Index and Japanese Orthopedic Association scores. Neurofunctional recovery of patients was assessed by the American Spinal Injury Association system., Results: Average follow-up was 8.9 ± 2.9 years (range, 5-15 years). Kyphosis angle and Neck Disability Index and Japanese Orthopaedic Association scores were significantly changed from preoperative values of 10.6° ± 8.9° and 39.7 ± 4.3 and 7.6 ± 2.4 to last follow-up values of -5.2° ± 8.6° and 10.8 ± 4.6 and 15.6 ± 1.2 (P < 0.05). Of patients, 197 (90.4%) had good to excellent outcomes, 14 (6.4%) had satisfactory outcomes, and 7 (3.2%) had poor outcomes. Varying degrees of neurologic function recovery were shown by 143 of the original 218 patients (65.6%) and 140 of 191 patients with incomplete paralysis (73.3%)., Conclusions: For lower cervical fracture-dislocation with spinal cord injuries, satisfactory clinical outcomes can be obtained with an anterior approach. The anterior approach restored normal cervical spine structure and promoted functional recovery to achieve a good long-term curative effect., (Copyright © 2018 Elsevier Inc. All rights reserved.)

Background: Atlanto-occipital dislocation (AOD) is a lesion rarely observed in a trauma center, because of high mortality in the preclinical phase. The number of AOD survivors is increasing thanks to the improvement in prehospital resuscitation., Case Description: Our goal is to describe a case of incomplete atlanto-occipital dislocation presented without any neurologic, cardiorespiratory, or metabolic problems, which remained constant even after surgical treatment. Our purpose is also to discuss treatment approaches to minimize subsequent neurologic deficits., Conclusions: We recommend a rapid immobilization with spine table and cervical collar, the consensual stabilization of hemodynamic and respiratory parameters, and a successive prompt occipitocervical stabilization. C2 should be included in the stabilization because of the ligamentous conformation of craniocervical joint., (Copyright © 2017 Elsevier Inc. All rights reserved.)

Background: The optimal treatment of displaced midshaft clavicle fractures (Robinson Type 2B1 & 2B2) in adults remains controversial. Little is known about patient satisfaction with treatment for this type of injury. The purpose of this study was to compare clinical outcomes and explore predictors of patient satisfaction after nonoperative and direct-operative treatment of displaced midshaft clavicle fractures in adults., Methods: A retrospective multicentre study was conducted. Clinical data were retrieved from electronic patient charts. A questionnaire informing on current subjective function (QuickDASH), pain levels (VAS), health-related quality of life (Eq-5D-5L), impact on employment and satisfaction with treatment results was sent to all patients. Univariate and multivariate linear regression was performed to identify predictors of satisfaction., Results: A total of 278 patients were identified (nonoperative n=150, direct-operative n=128). 67% of eligible patients returned the questionnaire. Median questionnaire follow-up was 2.1 years. No differences were found between groups for QuickDASH, Eq-5D-5L or pain VAS scores. Impaired union was observed in 13.2% of nonoperative cases vs. 2.3% in the direct-operative group. Patients in the nonoperative group could resume work after a median of 30.0days, compared to 13.5days in the direct-operative group. Patient satisfaction was higher in the direct-operative group, 8/10 vs. 7/10 for overall treatment results respectively. Patients' rating for the level of shared decision-making was the main predictor of overall satisfaction., Conclusion: Direct-operative management led to higher patient satisfaction, despite similar long-term patient reported outcomes with nonoperative treatment. Patients' rating for the level of shared decision-making was the main predictor of overall satisfaction. This study highlights the need to enhance communication to facilitate shared decision-making., (Copyright © 2017 Elsevier Ltd. All rights reserved.)

Background: Pedicle screw fixation of the lumbar spine in children age <2 years is particularly challenging, as successful cannulation of the small pedicle dimensions requires a high level of precision and there are no implants specifically designed for the infant spine. Image-guided navigation is commonly used in adult spinal surgery and may be particularly helpful for the placement of spinal screws in areas where the bony anatomy is small and/or anatomically complex, as in the upper cervical area., Case Description: A 19-month-old female presented with a fracture-dislocation injury of L1-2. Intraoperative imaging using the O-arm multidimensional imaging system was networked to a workstation, and neuronavigation was used to place pedicle instrumentation with 3.5-mm-diameter polyaxial screws designed for posterior cervical fixation. At a 48-month follow-up, the patient was neurologically intact, demonstrated normal physical development, and was engaging in normal physical activity for her age. Radiographs obtained approximately 4 years postsurgery showed no evidence of loss for fixation., Conclusions: Image-guided placement of pedicle screws may be a useful aid in achieving accurate and safe fixation in the small dimensions of the infant spine., (Copyright © 2017 Elsevier Inc.

Purpose: Fractures of the base of the middle phalanx are particularly challenging. Dorsal fracture-subluxations/dislocations of the proximal interphalangeal (PIP) joint are relatively common, but the volar fracture-subluxation/dislocation, the so-called "central slip fracture," is quite rare. The current study presents our experience with surgically treated patients with central slip fracture subluxation/dislocation with a minimum of 1 year follow-up. We hypothesized that the majority of patients with a central slip fracture-subluxation/dislocation have poor outcomes., Methods: Thirteen patients with central slip fracture-subluxations/dislocation were identified from departmental billing records between 2003 and 2013. Nine patients completed the study follow-up examination and 8 were included in the final analysis. Clinical data assessed included age at injury, sex, mechanism of injury, injured digit, type of treatment, additional intervention(s), complications, length of follow-up, and range of motion follow-up. Fluoroscopic images and Quick Disabilities of the Arm, Shoulder, and Hand surveys were obtained at study follow-up., Results: All patients underwent at least 1 surgery and 7 of 8 underwent open reduction. The average age at the time of injury was 41 years (range, 25-60 years). All injuries were closed. The average follow-up was 43 months (range, 17-67 months). Average passive and active range of motion of the PIP joint at follow-up were 62° and 54°, respectively. Six of 8 patients developed radiographic evidence of arthritic change and 4 experienced an outcome that required additional interventions., Conclusions: Patients should be counseled about the outcomes following surgical treatment of this uncommon, difficult injury., Type of Study/level of Evidence: Therapeutic V., (Copyright © 2017 American Society for Surgery of the Hand.

Background: There is very little information on the costs of different surgeries for displaced femoral neck fractures. This study aimed to compare the costs between internal fixation and hemiarthroplasty (HA) in the treatment of displaced femoral neck fracture., Method: A total of 142 patients aged 65 years or older who had been randomized into internal fixation group (n = 70) or HA group (n = 72) were followed for 2 years. Cost data was collected through hospitalization information, cost diary and telephone interview. Sensitivity analysis was performed for missing diaries. The total costs were collected and compared between the two groups., Results: All diaries were completed by 69.7% of patients. The mean costs of primary treatment were significantly lower for internal fixation (CNY 21,631) compared with HA (CNY 51,641) (p < 0.001). The mean post-discharge costs were similar for both procedures: CNY 37,377 for internal fixation and CNY 34,981 for HA (p = 0.640). The mean total costs for internal fixation were CNY 59,008, which was significantly lower than the mean total costs of CNY 86,622 for HA (p = 0.002)., Conclusion: Although the post-discharge costs of internal fixation were slightly higher, the total costs were still lower than for HA due to great variance in costs of primary treatment.

The aim of this study is to retrieve and bring back to light a part of the astonishing and painstaking work of the legendary Italian father of modern pathology Giovanni Battista Morgagni, concerning one of most discussed topics in spine surgery: spine fractures-dislocations. All the excerpts selected for this study are contained in De sedibus et causis morborum per anatomen indagatis, the summa maxima of the entire production of Morgagni. This treatise encloses the enormous experience of Morgagni in anatomic dissections and pathologic investigations. With the aid of a strict dissection and description methodology, Morgagni identified and described many of the most important aspects of spinal fractures-dislocations, from the importance of the mechanism of injury, to the relevance of ligamentous complex, or the risk of posttraumatic kyphosis and the clinical expression of spinal cord injury., (Copyright © 2016 Elsevier Inc.

Purpose: The optimal management of undisplaced scaphoid fractures remains controversial. A systematic review was conducted to assess the outcomes of acute, undisplaced scaphoid fractures managed with cast immobilization versus percutaneous or miniopen screw fixation in terms of time to return to work (RTW), time to union, and morbidity., Methods: PubMed MEDLINE, Ovid MEDLINE, EMBASE, SCOPUS, and Cochrane electronic databases were searched over the period 1974 to 2015. Key words included "scaphoid fracture," "navicular fracture," "hand," "immobilization," "cast," "conservative," "percutaneous," "screw fixation," "mini open," and "minimally invasive." A 2-step review process was done by 2 independent reviewers (H.A. and J.K.) using the following criteria: (1) acute undisplaced scaphoid fracture, (2) English language, (3) RTW duration objectively reported, (5) age older than 15 years, and (5) studies with more than 10 patients. Patient demographics, duration of immobilization, time to RTW, time to union, and complications were extracted. The methodological quality of each study included was assessed independently. Meta-analysis was performed for comparative trials., Results: Ten studies met the inclusion criteria: 6 comparative studies and 4 case series. Patients were divided into 2 groups: cast immobilization (group 1) and percutaneous fixation (group 2). Average time to RTW was 77 days for group 1 versus 46 days for group 2. Average time to radiographic union was 79 days for group 1 versus 44 days for group 2. There was no significant difference in complication rate between the groups (7% in group 1 vs 14% in group 2)., Conclusions: Percutaneous fixation of acute undisplaced scaphoid fractures has union rates comparable with those of nonsurgical cast immobilization but with faster RTW and time to union without a significant difference in complication rate., Type of Study/level of Evidence: Therapeutic II., (Copyright © 2016 American Society for Surgery of the Hand.

Purpose: To evaluate the outcomes of extension block pinning used to treat unstable dorsal fracture dislocations of the proximal interphalangeal (PIP) joint. The factors affecting the functional outcome were analyzed., Methods: A series of 53 patients with 55 dorsal fracture dislocations of the PIP joint treated with closed reduction and extension block pinning were retrospectively reviewed. Additional percutaneous intramedullary fracture reduction (16 cases) or open fracture reduction (4 cases) had been performed. The radiological and clinical evaluations were included., Results: At a mean follow-up of 5.2 years (range, 1.0-10.6 years), 39 patients with 41 injured fingers were evaluated. The fracture fragments involved 30% to 69% (mean, 50%) of the articular surface of the middle phalanx. The mean range of motion was 80° (range, 35° to 115°) at the PIP joint with a mean extension loss of 6° (range, 0° to 50°) excluding 2 joints that were salvaged with arthrodesis. The mean range of motion of the distal interphalangeal joint was 68° (range, 5° to 90°). The mean visual analog scale for digit pain was 1.5/10. The reduction of the joint was achieved intraoperatively in all cases. However, after the hardware removal, recurrent minimal subluxation was observed in 12 cases (29%). Recurrent subluxation was associated with increased residual pain. The length of follow-up time had a positive correlation, whereas the patient age had a negative correlation with the range of motion of the injured PIP joint., Conclusions: The extension block pinning technique is a simple and valuable technique for treating unstable dorsal PIP fracture-dislocation injuries producing satisfactory long-term results., (Copyright © 2016 American Society for Surgery of the Hand.

Purpose: The aim of this study was to assess a non-endoscopic transoral versus extraoral technique in the open reduction and internal fixation of displaced or dislocated fractures of the condylar neck., Material and Methods: A total of 104 patients, treated from 2007 to 2012 with 114 class II or class IV fractures according to Spiessl and Schroll were included in this study. Facial nerve function, scarring, pain and functional clinical parameters, such as protrusion, mediotrusion and maximum interincisal distance, were judged clinically (at 21 ± 12.1 months); repositioning and reossification were measured upon preoperative, postoperative and follow-up (at 8.8 ± 7 months) radiographs. Patient satisfaction was evaluated using the OHIP-G 14 questionnaire., Results: In all, 36 patients (35%) with 43 fractures (38%) presented for clinical follow-up. Both treatment groups showed clinically and radiologically comparable results. Scarring was obvious in all extraorally treated patients, and hypertrophic scars occurred in four class IV cases (24%). One class IV patient (6%) had a persistent facial nerve palsy; temporary pareses were more frequent (n = 4; 24%)., Conclusion: The transoral approach did not jeopardize facial nerve function, and extraoral scars were avoided. Repositioning and fixation results and the frequency of revision operations were comparable. The transoral approach can be recommended generally in class II and class IV cases., (Copyright © 2014 European Association for Cranio-Maxillo-Facial Surgery. Published by Elsevier Ltd.
