The objective of this study was to evaluate the clinical and radiological outcomes of reverse shoulder arthroplasty (RSA) associated with two techniques: L'Episcopo procedure (combined teres major and latissimus dorsi transfer) and modified L'Episcopo procedure (isolated latissimus dorsi transfer).A retrospective review of 36 RSAs (mean age 69.8 years; SD 8.9) associated with either L'Episcopo procedure (Group 1, 21 cases) or modified L'Episcopo procedure (Group 2, 15 cases) was performed between 2007 and 2020. Clinical outcome measures consisted of range of motion (ROM), SSV, VAS, and Constant-Murley scores. These scores were compared between the two groups. Radiographs were assessed for transfer site bony lesions.With a mean follow-up of 40.8 months (6-98; SD 28.8), no significant differences were revealed in the clinical outcomes: Constant score, SSV, VAS, ROM. The entire study group demonstrated a significant improvement in post-operative functional outcome scores and ROM parameters compared to their pre-operative state, IR measures being the only exception (p = 0.26). Radiographs demonstrated transfer site bony lesions in 60% of the patients (18/30). Three complications (8.3%) were noted in the study.At the short-term follow-up, RSA combined with either latissimus dorsi (LD) transfer in isolation or in association with teres major proved to be equally effective in restoring external rotation in the settings of an irreparable postero-superior cuff tear treated with RSA. Although the LD transfer group displayed a tendency towards superior ROM, this was not supported statistically. Post-operative radiographs confirmed the presence of bony lesions at the transfer fixation sites in both groups of patients (52% vs. 72%).

To report clinical and radiologic outcomes of arthroscopic Eden-Hybinette using 2 cortical suture buttons in a series of patients with previous failed Latarjet and persistent glenoid bone loss.Between 2015 and 2019, patients with recurrent anterior instability after failed Latarjet underwent arthroscopic Eden-Hybinette procedure using 2 cortical buttons for graft fixation. Exclusion criteria were open and primary Eden-Hybinette and less than one year follow-up. Functional assessment was performed using Rowe and Walch-Duplay scores, subjective shoulder value, visual analog scale, and degree of satisfaction. Iliac crest bone graft placement and healing were assessed postoperatively with computed tomography imaging.A total of 17 patients with a mean age of 28 years (range, 21-43 years) at time of revision were included. The mean glenoid bone loss was 23% (range, 18%-42%). Medium or deep Hill-Sachs lesion (Calandra 2 and 3) was present in 65% of cases. At a mean follow-up of 3 ± 1.6 years, all but 1 patient (94%) considered their shoulder stable, and 15 patients (88%) were satisfied or very satisfied. The subjective shoulder value increased from 51% to 87% (P.05), the Walch-Duplay increased from 23 to 86 points (P.05), and Rowe scores improved from 30 to 92 points (P.05). Apprehension was still positive in 3 patients (17.6%), with this percentage being greater in the presence of Hill-Sachs Calandra 3 (P = .02). Postoperative computed tomography scans showed optimal bone autograft position in all patients (below the glenoid equator and flush to the glenoid rim). Iliac crest bone graft healed to the anterior glenoid neck in 16 shoulders (94%). The rate of recurrent instability was 11.7% but only 1 patient required revision surgery (5.8%).Arthroscopic Eden-Hybinette using 2 cortical buttons leads to satisfactory clinical outcomes and a low recurrence rate after failed Latarjet, allowing successful reconstruction of the anterior glenoid rim and simultaneous treatment of capsular deficiency and humeral bone loss.Therapeutic, level IV, retrospective case series.

To evaluate long-term results after arthroscopic Bankart repair and Hill-Sachs remplissage (BHSR) in bipolar bone defects with less than 20% of glenoid bone loss (GBL) and to analyse risk factors for recurrent dislocation.From 2009-2012, 43 patients with recurrent anterior shoulder instability were treated with BHSR. Inclusion criteria were GBL 20% and minimum of 4-yearfollow-up. There were 35 males and 8 females with a mean age of 29 years (range 16-53). The mean ISIS score was 3.6 (range 2-6). Patients were evaluated for recurrence, range of motion and functional outcomes (Walch-Duplay and Rowe score). Post-operative MRI was performed at least 6 months after surgery to evaluate infraspinatus capsulotenodesis healing. Glenoid track was assessed retrospectively from pre-operative computed tomography. Mean follow-up was 7.3 years (range 4-11).At the last follow-up, good to excellent outcomes were reported in 86% of patients. Average post-operative Walch-Duplay was 87.9 (range 75-100) and ROWE 93.7 (range 70-100). Infraspinatus capsulotenodesis healing was achieved in 86%. The rate of recurrence and revision surgery was 9.3% and 13.9%, respectively. Recurrence was associated with higher ISIS score (p = 0.0191) and lower age at surgery (p = 0.0227). Four (9.3%) Hill-Sachs lesions were considered off-track. The presence of off-track Hill-Sachs was associated with higher risk of recurrence (p 0.00001).Arthroscopic BHSR improves shoulder instability in the setting of bipolar bone defects with less than 20% of GBL. Patient-related factors and pre-operative glenoid track should be taken into consideration to reduce the risk of recurrence.

PURPOSE OF REVIEW: The evaluation of proximal humerus fractures (PHFs) should be aimed to answer the following four questions: (1) does the fracture need surgery in each particular patient? (2) if surgery is recommended, is it better to proceed with internal fixation or shoulder arthroplasty, (3) if internal fixation is recommended, what is the ideal fixation device strategy, and (4) how can outcomes be optimized? This review article tries to answer these questions and provides some clarity regarding what works and what does not in PHFs treated with intramedullary nailing. RECENT FINDINGS: According to published articles on the treatment of PHFs with intramedullary nails, it is difficult to draw conclusions about outcomes and complications due to great variation in age, type of fracture, and nail designs included in the studies. However, the literature seems to support the use of modern nail designs for PHFs, especially in fractures of the surgical neck as well as varus posteromedial and valgus fractures with no tuberosity involvement. SUMMARY: Although the results of IMN in PHF seem to be better in two-part fractures, in more complex fractures, the quality of the reduction achieved seems to influence functional outcomes. Tuberosity malreduction leads to poor clinical outcomes, high rate of complications, and an increased risk of avascular necrosis. Malreduction of the humeral head increases the risk of postoperative loss of reduction, especially for varus posteromedial impacted fractures. A medial nail entry point decreases the risk of postoperative varus malunion, preserves the rotator cuff tendon, and avoids iatrogenic fractures of the GT. To decrease the risk of postoperative stiffness, fracture fixation should be stable enough to allow early mobilization.

PURPOSE OF REVIEW: The key question to answer during the decision-making process for proximal humerus fractures (PHF) is whether the amount of displacement of a specific fracture pattern will be acceptable taking into account the anticipated demands on the patient. The aim of this review article was to provide some clarity regarding the features that contribute to poor clinical outcomes when PHF are treated non-operatively and to review the reported outcomes of conservative treatment. RECENT FINDINGS: Conservative treatment for non-displaced or minimally displaced fractures leads to good outcomes in 80% to 90% of patients. However, with increasing fracture complexity and displacement, functional outcomes tend to diminish. In active patients with significant functional demands, the challenge is to predict which fractures will do poorly when treated non-operatively. SUMMARY: A better understanding of fracture patterns and fragment displacement may improve treatment indications. To avoid complications related to conservative treatment, surgery should be considered (1) in fractures in which the humeral head is severely compromised (due to fracture-dislocation, severe impaction, or a split of the head itself), (2) in non-impacted fractures with gross instability between the humeral shaft and humeral head, and (3) in those cases in which displacement of the tuberosities or the final shape of the proximal humerus after healing will lead to symptomatic malunion.

PURPOSE The aim of this study was to describe the results of an arthroscopic Trillat procedure utilized to treat patients with symptomatic antero-inferior shoulder instability associated with hyperlaxity. METHODS A retrospective review was performed on 19 consecutive shoulders (17 patients, 2 bilateral) who underwent a Trillat procedure combined with anterio-inferior capsulolabral plasty from 2016 to 2019. Patients included in the study presented with shoulder instability combined with shoulder hyperlaxity and no glenoid or humeral bone loss. Clinical assessment included range of motion, apprehension, and instability tests. Outcome measures Constant-Murley score (CMS) scale, Walch-Duplay, ROWE, Subjective Shoulder Value (SSV), Visual Analogue Scale (VAS). Post-operatively, healing of the coracoid osteoclasy was evaluated by CT scan. RESULTS The mean follow-up was 24.8 months (range, 12-51). Post-operatively, none of the patients experienced a recurrent dislocation or subluxation and the anterior apprehension test was negative in all shoulders. Post-operative motion deficits of 22.1° ± 15.8 [p

Screw tip augmentation with bone cement for fixation of osteoporotic proximal humerus fractures seems to improve stability and to decrease the rate of complications related to implant failure. However, the optimal augmentation combinations are unknown. The aim of this study was to assess the relative stability of two augmentations combinations under axial compression load in a simulated proximal humerus fractures fixed with locking plate.A surgical neck osteotomy was created in five pairs of embalmed humeri with a mean age of 74 years (range 46-93 years), secured with a stainless-steel locking-compression plate. In each pair of humeri, on the right humerus were cemented the screws A and E, and in the contralateral side were cemented screws B and D of the locking plate. The specimens were first tested cyclically in axial compression for 6000 cycles to evaluate interfragmentary motion (dynamic study). At the end of the cycling test, the specimens were loaded in compression force simulating varus bending with increasing load magnitude until failure of the construct (static study).There were no significant differences in interfragmentary motion between the two configurations of cemented screws in the dynamic study (p=0.463). When tested to failure, the configuration of cemented screws in lines B and D demonstrated higher compression load to failure (2218N vs 2105, p= 0.901) and higher stiffness (125 N/mm vs 106 N/mm, p 0.672). However, no statistically significant differences were reported in any of these variables.In simulated proximal humerus fractures, the configuration of the cemented screws does not influence the implant stability when a low-energy cyclical load is applied. Cementing the screws in rows B and D provides similar strength to the previously proposed cemented screws configuration and could avoid complications observed in clinical studies.

Most patients with primary osteoarthritis of the elbow report a history of heavy lifting with the affected upper extremity . Conservative treatment, including activity modifications, nonsteroidal anti-inflammatory drugs and the occasional intraarticular corticosteroid injection, may provide adequate pain relief in earlier stages . When surgery is required, and despite the presence of cartilage wear, many patients with primary elbow osteoarthritis experience substantial pain improvement with joint preserving procedures . The ulnar nerve needs to be carefully assessed and addressed at the time of surgery . Although open debridement procedures are effective, arthroscopic osteocapsular arthroplasty has emerged as the surgical procedure of choice . Total elbow arthroplasty is very successful in terms of pain relief and function, but it is reserved for patients with end-stage osteoarthritis who are relatively older and have failed joint preserving procedures.

Therapeutic management of recurrent anterior shoulder instability with an anterior glenoid defect and a Hill-Sachs lesion requires a bone graft to restore the width of the glenoid. The Latarjet procedure is the most popular technique but an iliac crest bone graft is preferred when the coracoid process is dysplastic or too short or after failure of Latarjet or Bristow-Latarjet. The purpose of this manuscript is to describe a full arthroscopic Eden-Hybinette-guided technique with 2 cortical suture buttons for bone graft fixation. This procedure allows reconstruction of severe glenoid bone defects and treatment of concomitant capsulolabral lesions and humeral bone loss, while preserving the subscapularis muscle. In addition, the use of 2 cortical buttons for bone graft fixation simplify graft transport and positioning, provides good control of the rotation, improving healing of the iliac crest bone graft to the anterior glenoid rim.

The term "pectoralis minor syndrome" refers to this constellation of symptoms that can occur when the pectoralis minor (Pm) is shortened and contracted. Release of the tendon of the Pm from the coracoid has been reported to provide substantial clinical improvement to patients presenting with pectoralis minor syndrome. The purpose of this study was (1) to describe the technique for endoscopic release of pectoralis minor tendon at the subdeltoid space, (2) to classify the pectoralis minor syndrome according to its severity and (3) and to report the short-term outcomes of this procedure in a consecutive series of patients diagnosed with pectoralis minor syndrome.Endoscopic release of the pectoralis minor tendon was performed in a series of 10 patients presenting with pectoralis minor syndrome. There were six females and four males with a median age at the time of surgery of 42 (range from 20 to 58) years. Four shoulders were categorized as grade I (scapular dyskinesis), and six as grade II (intermittent brachial plexopathy). Shoulders were evaluated for pain, motion, satisfaction, subjective shoulder value (SSV), quick-DASH, ASES score, and complications. The mean follow-up time was 19 (range, 6 to 49) months.Arthroscopic release of the tendon of the Pm led to substantial resolution of pectoralis minor syndrome symptoms in all but one shoulder, which was considered a failure. Preoperatively, the median VAS for pain was 8.5 (range, 7-10) and the mean SSV was 20% (range, 10% - 50%). At most recent follow-up the mean VAS for pain was 1 (range, 0-6) and the mean SSV 80% (range, 50% - 90%). Before surgery, mean ASES and quick-DASH scores were 19.1 (range, 10-41.6) and 83.1 (range, 71 and 95.5) points respectively. At most recent follow-up, mean ASES and quick-DASH scores were 80.1 (range, 40-100) and 19.3 (range, 2.3-68) points respectively. No surgical complications occurred in any of the shoulder included in this study.Endoscopic release of the tendon of the pectoralis minor from the coracoid improves pain, function and patient reported outcomes in the majority of patients presenting with the diagnosis of isolated pectoralis minor syndrome.

Reverse total shoulder arthroplasty (RSA) associated with modified L'Episcopo (isolated LD) or L'Episcopo (combined TM and LD) procedures had been confirmed to effectively overcome the expected external rotation deficit in patient with postero-superior massive cuff tear and teres minor deficiency. The objective of this study was to evaluate the radiological bony lesions of the lateral proximal humerus following RSA combined with tendon transfer, and to determine whether these bony lesions affect the clinical outcome.A retrospective review of 24 RSAs (mean age 68.71 years, range 52-83) associated with modified L'Episcopo procedure (9) and L'Episcopo procedure (15) was performed. X-rays were assessed for lateral cortex lesions and were categorized into either intact, irregular or complete lytic appearances. In addition, signs of stem loosening were assessed. Clinical outcome measures included range of motion, SSV, VAS, and Constant-Murley scores.With a mean follow-up of 44.71 months (12-97; SD 27.42), eight (33.3%) patients demonstrated intact lateral cortex, eight (33.3%) irregular and eight (33.3%) lytic lesions. 40% of cemented stems demonstrated a deformed cortex compared to 74% of cementless stems. Radiolucent lines were detected in one cemented stem (p=0.046). GT resorption (p=0.147), condensations lines (p=0.449) and spot weld (p=0.342), appeared exclusively in non-cemented stem. Postoperatively all patients (24) demonstrated significant improvements in all clinical and functional parameters. A comparison between patient with (Group 2, 16 patients) and without bony lesions (Group 1, 8 patients) revealed no significant differences in functional scores and range of motion: Constant (p=0,61), VAS (p=0,61), SSV (p=0,66) and external rotation (p=0,34).At short-term follow-up, RSA combined with L'Episcopo or modified l'Episcopo procedure resulted in high incidence (67%) of lateral proximal humerus lesions. Radiolucent lines were noted in cemented stems whereas, signs of stress shielding and GT resorption appeared in non-cemented stems. Yet, no case of humeral loosening was detected and these lesions did not seem to affect the clinical outcome. The use of cemented straight standard-length humeral stems should be positively considered in RSA associated with LD\TM tendon transfer.IV; retrospective study.

Background Persistent infection rate after 2-stage reimplantation complicating elbow arthroplasty has been reported to be as high as 25%. The purposes of this retrospective study were to determine the infection eradication rates, complications and outcomes in a cohort of patients treated with two-stage reimplantation for deep periprosthetic joint infection (PJI) following total elbow arthroplasty (TEA) and to determine possible associated risk factors for treatment failure. Methods Between 2000 and 2017, 52 elbows underwent a two-stage reimplantation for PJI after TEA. There were 22 males and 30 females with a mean age of 61 (range, 25–82) years. The most common bacterium was Staphylococcus epidermidis (28 elbows). Mayo Elbow Performance Scores were calculated at the latest follow-up. Mean follow-up time was 6 years (range, 2–14 years). Results PJI was eradicated in 36 elbows (69%). The remaining 16 elbows were considered treatment failures secondary to recurrent infection. The risk of persistent infection was 3.3 times higher in elbows with retained cement (p 0.04), and 3.5 times higher when the infecting organism was Staphylococcus epidermidis (p 0.06). Conclusion Two-stage reimplantation for PJI after TEA was successful in eradicating deep infection in 69% of cases. The eradication of PJI after TEA still needs to be improved substantially.

Aims The purpose of this study was to report bone adaptive changes after anatomical total shoulder arthroplasty (TSA) using a standard-length hydroxyapatite (HA)-coated humeral component, and to report on a computer-based analysis of radiographs to determine changes in peri-implant bone density objectively. Methods A total of 44 TSAs, performed between 2011 and 2014 using a cementless standard-length humeral component proximally coated with HA, were included. There were 23 males and 21 females with a mean age of 65 years (17 to 65). All shoulders had good quality radiographs at six weeks and five years postoperatively. Three observers graded bone adaptive changes. All radiographs were uploaded into a commercially available photographic software program. The grey value density of humeral radiological areas was corrected to the grey value density of the humeral component and compared over time. Results Stress shielding was graded as mild in 14 shoulders and moderate in three; the greater tuberosity was the predominant site for stress shielding. The mean metaphyseal and diaphyseal fill-fit ratios were 0.56 (SD 0.1) and 0.5 (SD 0.07), respectively. For shoulders with no radiologically visible stress shielding, the mean decrease in grey value in zones 1 and 7 was 20%, compared with 38% in shoulders with radiologically visible stress shielding. Conclusion The rate of moderate stress shielding was 7%, five years after implantation of a cementless standard-length HA-coated humeral component. Clinical observation of stress shielding identified on radiographs seems to represent a decrease in grey value of 25% or more. Cite this article: Bone Joint J 2021;103-B(5):958–963.
