Apprehension-Based Training: A Novel Treatment Concept for Anterior Shoulder Dislocation - A Case Report.

Background and Purpose: Conservative management of anterior shoulder dislocation (ASD) is associated with greater recurrence compared with surgical management. Current rehabilitation protocols may not adequately challenge shoulder stability to encourage adaptive coping strategies. Apprehension-based training (ABT) is a new treatment concept derived from the supine moving apprehension test (SMAT), a previously validated performance measure among patients with ASD. The purpose of this case report is to describe the application of ABT in a patient with recurrent ASD. Study Design: Case report. Case Description: The subject was a 23-year-old male with bilateral recurrent ASD. The subject underwent a 17-week exercise program involving gradual exposure to increased anterior instability loads based on the SMAT movement pattern. The Western Ontario Shoulder Instability Index (WOSI), Patient-Specific Functional Scale (PFPS), Tampa Scale of Kinesiophobia, SMAT, shoulder internal and external rotation muscle strength were measured via hand-held dynomometry before and after training. Outcomes: Following treatment, clinically meaningful gains in quality of life (WOSI) and shoulder function (PSFS) were noted. Kinesiophobia decreased, SMAT and shoulder internal rotator strength increased beyond their respective minimal detectable change. Four months after treatment, quality of life and shoulder function remained improved, and the subject reported a reduced rate of ASD. Discussion: Apprehension-based training involving gradual exposure to shoulder instability loads may hold potential for improving the management of patients with ASD. Further testing of this concept is warranted. Level of Evidence: 4, single case report.

Comprehensive Evaluation and Arthroscopic Management of Circumferential Labral Tears Following Traumatic First Time Shoulder Dislocation: A Case Report and Review.

Introduction: Pan-labral tears, commonly associated with recurrent shoulder dislocations, are a well-documented pathology. However, circumferential pan-labral tears following a first-time shoulder dislocation represent a rare and scarcely reported entity in the literature. Accurate diagnosis requires a comprehensive clinical history, physical examination, and further evaluation, often involving MRI. Even with advanced imaging, the acute nature of the injury can lead to the oversight of pan-labral tears, necessitating arthroscopic assessment for definitive diagnosis. Repairing such extensive glenoid labral tears presents a challenging task, requiring skilled surgeons to utilize accessory portals and percutaneous techniques for optimal visualization and anchor placement trajectory. To the best of our knowledge, this case report represents the first documentation of a pan-labral tear associated with a 1st-time shoulder dislocation. Case Report: A 27-year-old Asian male presented with pain and limited range of motion in the left shoulder following a single episode of anterior shoulder dislocation during cricket. Initial X-rays were unremarkable, but subsequent MRI revealed an anteroinferior labral tear with intact rotator cuffs. Arthroscopic evaluation disclosed a pan-labral tear, prompting meticulous repair under general and locoregional anesthesia. The patient achieved full recovery postoperatively. Conclusion: While pan-labral tears are typically linked to recurrent dislocations, this case underscores their occurrence in a 1st-time traumatic shoulder dislocation without overt clinical signs or fractures. Arthroscopic repair demands careful intraoperative planning to achieve optimal tensioning and alignment of labral and capsular tissues. This report contributes to the limited literature on pan-labral tears associated with initial shoulder dislocations, emphasizing the importance of arthroscopic evaluation for accurate diagnosis and successful repair.

[Mid-term effectiveness of LU-tarjet procedure for recurrent anterior shoulder dislocation].

Objective: To evaluate the mid-term effectiveness of limited unique coracoid osteotomy suture button fixation Latarjet (LU-tarjet) procedure in treatment of recurrent anterior shoulder dislocation. Methods: Between March 2017 and February 2019, 56 patients with recurrent shoulder dislocation were treated with arthroscopic LU-tarjet procedure. There were 44 males and 12 females with an average age of 26.3 years (range, 18-41 years). Shoulder joint dislocation occurred 2-16 times, with an average of 7.5 times. The time from the initial dislocation to operation ranged from 6 months to 13 years, with a median of 4.6 years. Preoperative shoulder joint fear test and re-reduction test were positive in all patients. The Beighton score of joint relaxation ranged from 1 to 7, with an average of 4.1. The shoulder Instability Severity Index Score (ISIS) ranged from 5 to 10, with an average of 7.8. The size of glenoid defects on the affected side ranged from 15% to 32% (mean, 22.4%). All patients had Hill-Sachs injuries of varying degrees. Six patients had re-dislocation after Bankart surgery. The operation time, incision healing, and postoperative complications were recorded. The range of motion (shoulder flexion, extension, abduction, external rotation, 90° external rotation, and internal rotation) and muscle strength in shoulder flexion, abduction, external rotation, and internal rotation) of shoulder joint were compared between pre- and post-operation. The improvement of shoulder function was evaluated using the American Association for Shoulder and Elbow Surgery (ASES) score, Walch-Duplay score, and Rowe score. X-ray films and three-dimensional CT were used to analyze the location, healing, and remolding of bone graft, the repair of glenoid defect, and degenerative changes of the shoulder joint. Results: All operations were successfully completed. The operation time ranged from 42 to 98 minutes, with an average of 63 minutes. All incisions healed by first intention. All patients were followed up 5-7 years (mean, 6.3 years). During follow-up, 2 patients experienced shoulder subluxation within 1 year after operation and 1 patient experienced recurrent shoulder joint pain. The remaining patients had no related complications. At last follow-up, there was no significant difference between the two groups ( P>0.05) in range of motion (shoulder flexion, extension, abduction, external rotation, 90° external rotation, and internal rotation) and muscle strength in shoulder flexion, abduction, external rotation, and internal rotation). The ASES score, Rowe score, and Walch-Duplay score of shoulder significantly improved when compared with those before operation ( P<0.05). Postoperative CT showed that 53 cases (94.64%) of coracoid bone masses were centered placed vertically, 2 cases (3.57%) were superior, and 1 case (1.79%) was inferior; 49 cases (87.50%) of the coracoid bone grafts were flush with the glenoid, 2 cases (3.57%) and 5 cases (8.93%) were medially and laterally positioned. The volume of coracoid bone graft decreased first and then increased, and the shape of the bone graft was continuously remodeling and gradually matched with the track of the humerus head (the optimal circle of the glenoid), all coracoid bone grafts healed. At last follow-up, the coverage rate of optimal glenoid circle was 89.6%-100%, with an average of 97.4%. The area of glenoid defect was 2.6%±1.3%, which significantly decreased when compared with preoperative (22.4%±5.4%) ( P<0.05). At last follow-up, no obvious degenerative changes of shoulder joint was observed. Conclusion: LU-tarjet procedure for recurrent anterior shoulder dislocation has good mid-term effectiveness with short operation time and few complications.

[Early-term effectiveness of Latarjet procedure by coracoid osteotomy with preserving coracoacromial ligament for recurrent anterior shoulder dislocation].

Objective: To evaluate the early-term effectiveness of Latarjet procedure with double EndoButtons fixation for recurrent anterior shoulder dislocation by coracoid osteotomy with preserving coracoacromial ligament. Methods: Between January 2021 and June 2023, 19 patients with recurrent anterior shoulder dislocations were treated by arthroscopic Latarjet procedure with double EndoButtons fixation, all of which underwent coracoid osteotomy with preserving the coracoacromial ligament. There were 11 males and 8 females, with an average age of 23.3 years (range, 17-32 years). Shoulder dislocations ranged from 3 to 11 times, with an average of 6.4 times. The disease duration ranged from 3 to 35 months, with an average of 12.9 months. All apprehension tests were positive. Imaging examination showed that the defect width of the ipsilateral glenoid bone was 13%-26%, with an average of 19.8%. After operation, the shoulder range of motion was examined, including flexion lift, lateral external rotation, extension 90° external rotation, and internal rotation. Shoulder joint function was evaluated by Walch-Duplay score, American Association for Shoulder and Elbow Surgery (ASES) score, and Rowe score. Imaging examinations were taken to observe the position and shaping of coracoid. Results: All incisions healed by first intention and no nerve or vessel injury occurred. All patients were followed up 9-24 months (mean, 14.5 months). There was no recurrence of shoulder dislocation and the apprehension tests were negative during follow-up. There was no significant difference in the shoulder range of motion (flexion lift, lateral external rotation, extension 90° external rotation, and internal rotation) between preoperation and at last follow-up ( P>0.05). The Walch-Duplay score, ASES score, and Rowe score significantly improved when compared with those before operation ( P<0.05). Postoperative imaging showed that coracoid graft was at the same level with the glenoid in all cases; the center of coracoid graft was located between 3 to 5 o'clock. During follow-up, there was no glenohumeral joint degeneration, the acromiaohumeral distance was not reduced when compared with preoperation, and the coracoid bone gradually formed concentric circles with the humeral head. Conclusion: The Latarjet procedure with double EndoButtons fixation can effectively treat recurrent anterior shoulder dislocation by coracoid osteotomy with preserving coracoacromial ligament, and the early-term effectiveness is satisfactory.

[Effectiveness analysis of double EndoButton suture fixation Latarjet procedure for treatment of anterior shoulder dislocation with glenoid bone defect caused by military training injuries].

Objective: To investigate the effectiveness of double EndoButton suture fixation Latarjet procedure in the treatment of shoulder anterior dislocation with glenoid bone defect caused by military training injuries. Methods: The clinical data of 14 patients with anterior shoulder dislocation with glenoid bone defect due to military training injuries who met the selection criteria and admitted between August 2021 and December 2022 were retrospectively analyzed. All patients were male, the age ranged from 21 to 38 years, with an average of 26.8 years. The time from initial dislocation to operation was 6-15 months, with an average of 10.2 months. Anterior shoulder dislocation occurred 5-12 times, with an average of 8.2 times. All glenoid bone defects were more than 10%, including 5 cases of 10%-15%, 8 cases of 15%-20%, and 1 case of 24%. All patients were treated by double EndoButton suture fixation Latarjet procedure. The operation time and complications were recorded. The shoulder function and pain were evaluated by the American Association for Shoulder and Elbow Surgery (ASES) score, Rowe score, Instability Severity Index Score (ISIS), and visual analogue scale (VAS) score before and after operation. The range of motion of the shoulder was recorded, including forward flexion, 0° external rotation, and abduction 90° external rotation. The position, healing, and resorption of the bone mass were evaluated by three-dimensional CT of shoulder joint after operation. Results: All patients successfully completed the operation, and the operation time was 100-150 minutes, with an average of 119.7 minutes. There was no complications such as infection, vascular and nerve injury. All patients were followed up 12-20 months, with an average of 15.6 months. During the follow-up, 4 patients had bone mass separation, absorption, and recurrent anterior dislocation, and the shoulder joint fear test was positive. Imaging of the remaining patients showed that the bone mass healed well, no anterior dislocation recurrence occurred, and the healing time was 3-7 months (mean, 4.7 months). At last follow-up, the range of motion, ASES score, Rowe score, ISIS score, and VAS score of the patients significantly improved when compared with those before operation ( P<0.05). Conclusion: The effectiveness of double EndoButton suture fixation Latarjet procedure for the treatment of anterior shoulder dislocation with glenoid bone defect caused by military training injury is satisfactory.

[Development and research progress of suture button fixation Latarjet procedure].

Objective: To review the development and research progress of suture button fixation Latarjet procedure. Methods: A comprehensive literature review was conducted to summarize the development and related modified techniques of the suture button fixation Latarjet procedure. Results: Since the Latarjet procedure was first introduced by French scholar Latarjet in 1954, it has undergone three key transformations, resulting in suture button fixation Latarjet procedure, which has shown satisfactory outcomes in treatment of recurrent shoulder dislocation. However, there are still drawbacks such as the risk of impingement of the graft on surrounding tissues, and the surgical disruption of anatomical structures like the coracoclavicular ligament and the pectoralis minor muscle. The scholars have proposed several modified techniques based on the suture button fixation Latarjet procedure to further reduce complications from impingement of the graft, to lower the glenohumeral contact pressure, and to eliminate the impact of surgery on the physiological structures of the shoulder joint. The modified techniques include the arthroscopic suture button fixation Latarjet procedure using FiberTape Cerclage, reconstruction of the coracoacromial ligament during congruent-arc Latarjet procedures, and limit unique coracoid osteotomy suture button Latarjet procedure (LU-tarjet procedure). These modified techniques have also shown good clinical outcomes. Additionally, other related modified techniques for reconstruction of the glenoid, such as Chinese unique Inlay Bristow procedure (Cuistow procedure), arthroscopic glenoid bone grafting with soft fixation, and all-arthroscopic modified Eden-Hybinette procedure, have also demonstrated favorable efficacy. However, there is still a lack of long-term follow-up results for these techniques and comparative studies between them. Conclusion: Suture button fixation Latarjet procedure is an effective method for the treatment of recurrent shoulder dislocation. There are various techniques, but there is no recognized gold standard, and further clinical and basic research is needed.

[Application of LU-tarjet congruent-arc technique in treatment of recurrent shoulder dislocation with huge glenoid defect].

Objective: To investigate the early effectiveness of the limited unique coracoid osteotomy suture button fixation Latarjet (LU-tarjet)-congruent-arc (CA) technique (LU-tarjet-CA) in treating recurrent shoulder dislocations with huge glenoid defect. Methods: The clinical data of 12 patients with recurrent shoulder dislocation and huge glenoid defect who met the selection criteria and treated with arthroscopic LU-tarjet-CA between January 2021 and December 2023 were retrospectively analyzed. The cohort included 8 males and 4 females, aged 20-40 years with an average age of 30.4 years. The range of glenoid bone loss was 30%-40%, with an average of 35.5%. The time from symptom onset to hospital admission ranged from 1 to 36 months, with an average of 18.5 months. The University of California Los Angeles (UCLA) score, American Association for Shoulder and Elbow Surgery (ASES) score, Walch-Duplay score, and Rowe score were used to evaluate shoulder function preoperatively and at 3, 6, and 12 months postoperatively. CT three-dimensional (3D) reconstruction was used to assess coracoid healing and plasticity at 3, 6, and 12 months postoperatively. Subjective satisfaction of patient was recorded at last follow-up. Results: All incisions healed by first intention, with no incision infection or nerve injury. All 12 patients were followed up 12 months. One patient developed Propionibacterium acnes infection within the joint postoperatively and recovered after initial arthroscopic debridement and anti-inflammatory treatment. At 3 months after operation, CT 3D-reconstruction showed 1 case of complete coracoid absorption; neither of these two patients experienced redislocation. The remaining patients exhibited partial coracoid absorption but displayed local reshaping, filling the preoperative defect area, and bony fusion between the coracoid and the glenoid. At last follow-up, 9 patients (75%) were very satisfied with the outcome, and 3 patients (25%) were satisfied; the satisfied patients experienced postoperative shoulder stiffness caused by suboptimal functional exercise but did not have impaired daily life activities. The UCLA score, ASES score, Walch-Duplay score, and Rowe score at 3, 6, and 12 months postoperatively were significantly better than preoperative scores, and each score improved further over time postoperatively, with significant differences between different time points ( P<0.05). Conclusion: The arthroscopic LU-tarjet-CA technique for treating recurrent shoulder dislocations with huge glenoid defect can achieve the surgical objective of bony blockade and filling bone defects to prevent shoulder dislocation, thereby improving patients' quality of life and shoulder joint function and stability.

[Mid-term effectiveness of modified arthroscopic suture button fixation Latarjet procedure for treatment of recurrent anterior shoulder dislocations].

Objective: To summarize mid-term effectiveness of modified arthroscopic suture button fixation Latarjet procedure for treatment of recurrent anterior shoulder dislocations. Methods: Between January 2018 and October 2020, 30 patients with recurrent anterior shoulder dislocations were treated with modified arthroscopic suture button fixation Latarjet procedure. There were 19 males and 11 females with an average age of 27.3 years (range, 18-41 years). The shoulder dislocation occurred 3-7 times, with an average of 4.9 times. The time from the last dislocation to operation was 3-10 days, with an average of 4.1 days. Glenoid defects exceeded 20% in all cases. There were 27 cases of Hill-Sachs lesions. The joint pain and function were estimated by visual analogue scale (VAS) score, University of California, Los Angeles (UCLA) score, Rowe score, American Association for Shoulder and Elbow Surgery (ASES) score, Walch-Duplay score, and the range of external rotation at 0° and external rotation at 90° abduction of shoulder before operation and at 1 month, 6 months, and last follow-up. The X-ray film, CT scan and three-dimensional reconstruction were reviewed to observe the position, healing, and absorption of the coracoid graft, correction of glenoid defect, and joint degeneration. Results: The operation time ranged from 51 to 79 minutes, with an average of 68.4 minutes. All incisions healed without complications such as nerve or blood vessel injury. All patients were followed up 36-60 months with an average of 44.6 months. The VAS score, UCLA score, Rowe score, ASES score, Walch-Duplay score, and the range of external rotation at 0° and external rotation at 90° abduction after operation significantly improved when compared with preoperative values ( P<0.05). All indicators further improved with time, and the differences between different time points after operation were significant ( P<0.05). Imaging review showed that the coracoid graft was located in the anteroinferior glenoid at 1 day after operation, and no occurrence of shoulder osteoarthritis was found during follow-up. The anatomical structure of the glenoid was normal, and no delayed healing or non-union of the coracoid graft occurred. At 20 months after operation, arthroscopic re-exploration was performed in 1 case due to fracutre caused by falling injury revealed the good shaping of the coracoid graft, smooth glenoid, and no bone resorption or osteoarthritis. Conclusion: For recurrent anterior shoulder dislocations, the modified arthroscopic suture button fixation Latarjet procedure can obtain good recovery of shoulder function and low incidence of complications and has a good mid-term effectiveness.

[Surgical accidents and postoperative complications of recurrent shoulder dislocation treated by suture button fixation with bone occlusion].

Objective: To summarize the surgical accidents and postoperative complications of the treatment of recurrent shoulder dislocation by suture button fixation and bone occlusion, and to provide clinical reference. Methods: The clinical data of 16 patients with recurrent shoulder dislocation treated with modified arthroscopic Latarjet suture button fixation and bone occlusion between July 2017 and April 2023 were retrospectively analyzed. Among them, 15 were male and 1 was female. The age ranged from 16 to 45 years, with an average of 26 years. Admission examination showed the range of motion of shoulder joint was normal; the shoulder joint fear test was positive; En-face CT scan measured 10%-20% of the glenoid defects, averaging 13.4%; and MRI examination revealed bone Bankart injury. The disease duration ranged from 2 to 20 years, with an average of 7.1 years. The shoulder joint was dislocated 8- 45 times, with an average of 17.4 times, and the shoulder joint was unstable. The occurrence of surgical accidents and postoperative complications as well as corresponding measures and outcomes were recorded. Results: All the incisions healed by first intention without any complications such as incision infection or vascular injury. All 16 cases were followed up for an average of 3.6 years (range, 1-7 years), and no shoulder redislocation occurred. Four types of intraoperative surgical accidents and two types of postoperative complications occurred in the early stage of implementation of the technique. Intraoperative surgical accidents included 1 case of difficulty in passing subscapular muscle through coracotomy with large size, which was treated with exchange rod or finger through subscapular muscle split; 2 cases of coracoidal process fracture, of which 1 case was treated conservatively, and the other case was sutured to the base of tendon and fixed through tunnel; 1 case of glenoid fracture occurred in the glenoid tunnel, which was fixed with knot-free anchors; the posterior loop plate fixation was abnormal in 2 cases, of which 1 case was re-fixed and the other case was renovated. Postoperative complications included coracoid bone mass displacement in 1 case, conservative biceps rehabilitation was given to avoid premature external rotation; 1 case of radial nerve injury of healthy upper limb and musculocutaneous nerve injury of affected side was given oral medication and physiotherapy. The above conditions recovered well after corresponding treatment. Conclusion: Suture button fixation with bone occlusion is a safe method for the treatment of recurrent shoulder dislocation. Careful operation should be performed during coracoid interception and glenoid tunnel drilling, especially in the fixation process.

Is Revision Arthroscopic Bankart Repair a Viable Option? A Systematic Review of Recurrent Instability following Bankart Repair.

Background/Objectives: Recurrent shoulder instability following Bankart lesion repair often necessitates surgical revision. This systematic review aims to understand the failure rates of arthroscopic revision Bankart repair. Methods: Following the PRISMA guidelines and registered on PROSPERO, this systematic review examined twenty-five articles written between 2000 and 2024. Two independent reviewers assessed eligibility across three databases, focusing on recurrent instability as the primary endpoint, while also noting functional measures, adverse events, revision operations, and return-to-sport rates when available. Results: The key surgical techniques for recurrent instability post-Bankart repair were identified, with revision arthroscopic Bankart being the most common (685/1032). A comparative analysis revealed a significantly lower recurrence for open coracoid transfer compared to arthroscopic revision Bankart repair (9.67% vs. 17.14%; p < 0.001), while no significant difference was observed between remplissage plus Bankart repair and Bankart repair alone (23.75% vs. 17.14%; p = 0.24). The majority of studies did not include supracritical glenoid bone loss or engaging Hill-Sachs lesions, and neither subcritical nor non-engaging lesions significantly influenced recurrence rates (p = 0.85 and p = 0.80, respectively). Conclusions: Revision arthroscopic Bankart repair remains a viable option in the absence of bipolar bone loss; however, open coracoid transfer appears to have lower recurrence rates than arthroscopic Bankart repair, consistent with prior evidence. Further studies should define cutoffs and investigate the roles of critical glenoid bone loss and off-track Hill-Sachs lesions. Preoperative measurements of GBL on three-dimensional computed tomography and characterizing lesions based on glenoid track will help surgeons to choose ideal candidates for arthroscopic revision Bankart repair.

Extensive skin laceration on the forearm due to closed reduction of a dislocated shoulder. A case report.

We report the case of an 80-year-old man who suffered an anteroinferior shoulder dislocation with rupture of the rotator cuff following a fall. An attempt at closed reduction under analgosedation resulted in extensive skin laceration on the elbow and forearm. The wound treatment was complex and resulted in numerous complications.

Neglected Anterior Shoulder Dislocation With Greater Tuberosity Fracture Managed With Open Reduction and Latarjet Procedure: A Case Report.

Neglected shoulder dislocation is a relatively rare occurrence characterized by structural changes in bone and soft tissue. Surgical intervention is often necessary, yet no universally accepted treatment approach exists, presenting a challenging clinical scenario. A 45-year-old female presented with an eight-month-old neglected anterior shoulder dislocation, compounded by a Hill-Sachs lesion from a previous fall. Treatment comprised open reduction in conjunction with the Latarjet procedure. Regular follow-up evaluations were conducted over three years post-surgery, revealing satisfactory outcomes including good range of motion, bony union, and absence of dislocation episodes. Managing neglected shoulder dislocations, particularly those with significant bone defects, poses unique challenges involving soft tissue contracture, bone loss, and associated fractures. Despite these complexities, open reduction combined with the Latarjet procedure demonstrated a high success rate in preventing further shoulder dislocation, albeit with a persistent risk of shoulder joint osteoarthritis.

Adherence of Patients to Methods of Self-Reduction of Shoulder Dislocation Taught via Smartphones: A Medium-Term Follow-up Survey.

INTRODUCTION: Self-reduction of a shoulder dislocation may reduce the time from injury to reduction and to the relief of patient discomfort. The purpose of this study was to assess adherence to earlier acquired self-reduction techniques during real-time recurrent shoulder dislocation. METHODS: A telephone survey was conducted among 58 patients previously taught shoulder self-reduction via an instructional video sent to their smartphones during a visit to the emergency department (ED) for the treatment of anterior shoulder dislocation. Participants were queried on recurrent dislocations, use of self-reduction methods, success rate, the effect that instruction in self-reduction had on their willingness to participate in recreational sports activities, on the decision to avoid surgery, and on the overall level of satisfaction with self-reduction methods. RESULTS: Forty-five patients (77.6%; average age 31.4±11.7 y, 10 females) were available for follow-up at an average 60.8±11.0 mo after the index visit to the ED. Eighteen of 23 patients (78.2%) who experienced a recurrent dislocation during the follow-up period attempted self-reduction, and 12 of them successfully achieved self-reduction. Sixteen patients (35.6%) reported that the knowledge in self-reduction increased their willingness to participate in recreational sports activities, whereas 4 (8.9%) patients reported that knowledge in self-reduction affected their decision not to undergo surgical stabilization. CONCLUSIONS: Individuals who sustain recurrent shoulder dislocations should be educated on shoulder self-reduction with the aims of minimizing discomfort, obviating referral to the ED, and motivating participation in recreational activities.

Efficacy of supervised self-reduction vs. physician-assisted techniques for anterior shoulder dislocations: a systematic review and meta-analysis.

BACKGROUND AND OBJECTIVE: Reduction manipulation using self-reduction procedures such as Stimson, Milch, and Boss-Holtzach should be easy and effective and also require less force, pain medication, and outside assistance. This technique should not cause damage to arteries, nerves, or shoulder joint components. Self-reduction is straightforward and can be done in clinics, making it ideal for people who suffer from shoulder joint dislocation frequently. The goal of this study is to compare the effectiveness of supervised self-reduction procedures vs. physician-assisted treatments in the treatment of anterior shoulder dislocations. METHOD: We conducted a comprehensive search on PubMed, Scopus, Web of Science, and Cochrane up to March 22, 2023, using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist. Relevant articles were reviewed, with a focus on studies comparing supervised self-reduction techniques to physician-assisted techniques in cases of anterior shoulder dislocation. RESULTS: Four papers in all were included in the meta-analysis. One prospective trial, one case-control study, one randomized clinical trial, and one retrospective trial made up these studies. The studies involved 283 patients in the physician-assisted group and 180 patients in the supervised self-reduction group. They were carried out in four European countries: Italy, Germany, Portugal, and Spain. The success rate of supervised self-reduction techniques was significantly higher, with an odds ratio of 2.71 (95% CI 1.25-5.58, p-value = 0.01). Based on the Visual Analog Scale (VAS) score, the physician-assisted group reported significantly higher maximum pain, with a mean difference of 1.98 (95% CI 1.24-2.72, p-value < 0.01). The self-reduction approaches exhibit shorter reduction time in comparison to physician-assisted groups. In addition, the self-reduction groups do not document any complications. Based on the GRADE system, the level of assurance in the evidence was high. CONCLUSION: Supervised self-reduction techniques outperform in terms of success rate and reduction-related maximum pain. These techniques could be used as an effective first-line treatment for anterior shoulder dislocation, potentially reducing the need for analgesics and emergency room visits.

Arthroscopic Fixation of Acute Large Bony Bankart with Suture-assisted Reduction and Screw Fixation - Surgical Technique.

Introduction: Glenoid rim fractures with Bankart lesions are called bony Bankart lesions and are associated with persistent glenohumeral joint instability. Acute bony Bankart lesions can be treated by various arthroscopic techniques. Here, we present a technique of arthroscopic bony Bankart repair using suture-assisted reduction and screw fixation. Discussion: The conventional suture anchor repair does not provide compression of the fractured fragment, and the bony piece may tilt because of the single-point fixation. Conclusion: This procedure can achieve firm compression between the bony fragments and prevent rotation of fragment during screw fixation to the glenoid. The capsular plication distributes the loads to the surrounding soft tissues. Hence, this procedure should be offered to all patients presenting acutely with a large bony Bankart of size >25% of glenoid width, as it is minimally invasive as well as provides excellent outcomes and anatomical union.

Median Nerve Palsy after Shoulder Dislocation in a 10-year-old Girl: A Case Report.

Introduction: Traumatic glenohumeral dislocation is very rare in skeletally immature patients, and there are no reports in the literature describing the risk of associated nerve injuries. In the general population, the most commonly affected nerve is the axillary, but anatomical variations with a common origin between the musculocutaneous and median nerves exist that alter the respective positions and courses of these nerves and can make them more prone to injury during a glenohumeral dislocation. Case Report: A 10-year-old girl presented with incomplete median nerve palsy without any recuperation 8 months after an anterior glenohumeral dislocation. Surgical exploration was performed and revealed a common origin of the musculocutaneus and median nerve, with bifurcation just distal to the glenohumeral joint, making it susceptible to compression-elongation trauma during dislocation. A careful neurolysis was performed, and there was a complete recovery of median nerve function. Conclusion: Glenohumeral dislocation associated with nerve injury is very rare in children. When a nerve injury occurs, one should be aware of possible anatomical variations of the infraclavicular plexus.

Serial Magnetic Resonance Arthrography for a Midsubstance Capsular Tear in a Patient With Traumatic Anterior Shoulder Instability.

The natural history of midsubstance capsular tears (MCTs) is unclear. We herein describe a case of MCT observed using serial magnetic resonance (MR) arthrography. A 46-year-old woman presented with excessive external rotation of the left glenohumeral joint, resulting in an initial anterior dislocation of the left shoulder. She subsequently developed recurrent shoulder joint dislocations. MR arthrography revealed an MCT without a Bankart lesion three months after the initial dislocation. She opted for nonoperative treatment, but the shoulder instability did not improve. The second MR arthrography, nine months after the initial dislocation, showed no natural healing of the MCT. The third MR arthrography, 12 months after the initial dislocation, also showed no natural healing. Her shoulder instability remained persistent. The patient then decided to have surgery. Arthroscopy revealed a large capsular defect extending from the glenoid to the humeral head in the anterior inferior glenohumeral ligamentous complex. The MCT was repaired with the placement of nonabsorbable sutures in a side-to-side fashion. At the final follow-up, three years postoperatively, the patient had no anterior shoulder instability. The Rowe score was 100 points. MR arthrography showed good repair integrity of the MCT at one year postoperatively. Serial MR arthrography was useful for both the patient and the shoulder surgeon in considering the treatment of the MCT, facilitating an accurate and qualitative assessment of whether natural healing of the MCT had been achieved.

Long-term results of arthroscopic capsulolabral revision repair for failed anterior shoulder instability repair using suture anchors at a minimum of 10 years follow-up.

INTRODUCTION: Arthroscopic revision anterior shoulder instability repair has been proposed, and early clinical results have been promising. However, long-term results after this procedure and the probable risk factors for failure have not been sufficiently discussed in the literature. MATERIALS AND METHODS: Thirty-eight patients who were diagnosed with recurrent anteroinferior shoulder instability after failed Bankart repair, treated with ACRR between September 1998 and November 2003 and able to be contacted were included. Of these patients, 2 were excluded from the study due to the use of SureTak anchors for fixation, and 5 other patients refused to participate in the study due to lack of interest (3 patients) or lack of time (2 patients). The remaining shoulders were clinically examined at a minimum of ten years after surgery via the ASES, Constant, AAOS, Rowe, Dawson and VAS scores for pain and stability. Degenerative arthropathy was assessed with the modified Samilson-Prieto score. RESULTS: All 31 remaining shoulders were evaluated at a mean time of 11.86 years (142.4 months) after surgery. Six patients (19.35%) reported redisolcation after the revision procedure, 4 of whom were affected by a new significant shoulder trauma. The ROWE and Constant scores improved significantly. Moderate to severe dislocation arthropathy was observed in 19.4% of patients. Five patients (16.2%) were not satisfied with the procedure. CONCLUSION: Long-term follow-up after ACRR shows predictable results, with a high degree of patient satisfaction, good to excellent patient-reported outcome scores and minimal radiological degenerative changes. However, with an average recurrence rate of 19.3% after 11.86 years, the redislocation rate appears high. With careful patient selection, recurrence rates can be significantly reduced.
