distal tibia allograft glenoid reconstruction in recurrent Anterior Shoulder instability clinical and radiographic outcomes
Arthroscopy, 2017Co-Authors: Matthew T Provencher, Rachel M Frank, Nikhil N Verma, Brian J Cole, Petar Golijanin, Daniel P Gross, Anthony A RomeoAbstract:Purpose To assess the clinical and radiographic outcomes of patients with recurrent Anterior Shoulder instability treated with fresh distal tibia allograft (DTA) glenoid reconstruction. Methods Consecutive patients with a minimum 15% Anterior glenoid bone loss associated with recurrent Anterior instability who underwent stabilization with DTA glenoid reconstruction were retrospectively reviewed. Patients were evaluated with the American Shoulder and Elbow Society score, Western Ontario Shoulder instability index, and single numerical assessment evaluation score at a minimum 2 years after surgery. All patients also underwent postoperative imaging evaluation with computed tomography where graft incorporation and allograft angle were measured. Statistical analysis was performed with paired t -tests, with P Results A total of 27 patients (100% male) with an average age of 31 ± 5 years and an average follow-up of 45 months (range, 30-66) were included. There were significant improvements in preoperative to postoperative American Shoulder and Elbow Society score (63-91, P P P Conclusions At an average follow-up of 45 months, fresh DTA reconstruction for recurrent Anterior Shoulder instability results in a clinically stable joint with excellent clinical outcomes and minimal graft resorption. Optimal allograft placement resulted in superior bony incorporation with the native glenoid. Level of Evidence Level IV, therapeutic case series.

identification and treatment of existing copathology in Anterior Shoulder instability repair
Arthroscopy, 2015Co-Authors: Brian Forsythe, Rachel M Frank, Mohammed Ahmed, Nikhil N Verma, Brian J Cole, Anthony A Romeo, Matthew T Provencher, Shane J NhoAbstract:Recurrent Anterior instability is a common finding after traumatic glenohumeral dislocation in the young, athletic patient population. A variety of concomitant pathologies may be present in addition to the classic Bankart lesion, including glenoid bone loss; humeral head bone loss; rotator interval pathology; complex/large capsular injuries including humeral avulsions of the glenohumeral ligaments (HAGL lesions), SLAP tears, near circumferential labral tears, and Anterior labral periosteal sleeve avulsions (ALPSA lesions); and rotator cuff tears. Normal anatomic variations masquerading as pathology also may be present. Recognition and treatment of these associated pathologies are necessary to improve function and symptoms of pain and to confer Anterior Shoulder stability. This review will focus on the history, physical examination findings, imaging findings, and recommended treatment options for common sources of copathology in Anterior Shoulder instability repair.

glenoid bone deficiency in recurrent Anterior Shoulder instability diagnosis and management
Journal of The American Academy of Orthopaedic Surgeons, 2009Co-Authors: Dana P Piasecki, Nikhil N Verma, Anthony A Romeo, William N Levine, Bernard R Bach, Matthew T ProvencherAbstract:Recurrent Anterior Shoulder instability may result from a spectrum of overlapping, often coexistent factors, one of which is glenoid bone loss. Untreated, glenoid bone loss may lead to recurrent instability and poor patient satisfaction. Recent studies suggest that the glenoid rim is altered in up to 90% of Shoulders with recurrent instability, thus underscoring the need for careful diagnosis, quantification, and preoperative evaluation. Biomechanical and clinical studies offer criteria that may be used in both primary and revision settings to judge whether Shoulder stability is compromised by a bony defect. Along with patient activity level, these criteria can help guide the surgeon in selecting treatment options, which range from nonsurgical care to isolated soft-tissue repair as well as various means of bony reconstitution.

arthroscopic stabilization in Anterior Shoulder instability collision athletes versus noncollision athletes
Arthroscopy, 2006Co-Authors: Nam Su Cho, Jung Chul Hwang, Yong Girl RheeAbstract:Purpose: Collision athletes have been reported to be at high risk of redislocation after stabilization for Anterior Shoulder instability. However, few studies have compared the results of arthroscopic stabilization with collision and noncollision athletes. The purposes of this study were to analyze clinical outcomes of arthroscopic Anterior Shoulder stabilization in athletes and to compare the results between collision and noncollision athletes. Methods: A total of 29 athletes were enrolled in this study, including 14 collision athletes and 15 noncollision athletes. Mean age at the time of operation was 21.1 years, and mean follow-up period was 62.1 months (range, 25 to 117 months). All Shoulders underwent arthroscopic stabilization. Results: Visual analogue scale score, Rowe score, and Constant score improved after surgery ( P P P = .118). Conclusions: Arthroscopic stabilization for Anterior instability of the Shoulder is a reliable procedure with respect to Shoulder function, range of motion, and postoperative return to sports activities in athletes. However, a high recurrence rate (17.2%) was observed among athletes. Compared with the noncollision group (6.7%), the collision group yielded a higher failure rate (28.6%) than was expected. Level of Evidence: Level IV, prognostic case series.

effectiveness of latarjet for Anterior Shoulder instability in patients with seizure disorder
JSES international, 2021Co-Authors: Stephen G Thon, Rachel M Frank, Katherine Branche, Darby A Houck, Tracey Didinger, Armando F Vidal, Jonathan T BravmanAbstract:Background A paucity of literature exists on the outcomes after Latarjet for Anterior Shoulder instability in patients with seizure disorders (SDs). The purpose of this study was to determine the effectiveness of the Latarjet procedure for Anterior Shoulder instability in patients with SDs. Methods A retrospective review of patients undergoing Latarjet from 2013 to 2017 for Anterior Shoulder instability with minimum 2 years of clinical follow-up was performed. Patients were divided into two groups: patients diagnosed with SD, and patients without a history of seizure (control). Demographics, indications, SD details, and postoperative outcomes were collected. The incidence of complications, recurrent instability, revision surgery, and repeat seizure(s) were also examined. Results A total of 53 patients were identified, including 10 Shoulders in 9 patients with an SD (88.9% male; mean age, 29.2 years [range, 20-37]), and 44 Shoulders in 44 non-SD patients (86.4% male; mean age, 30.3 years [range, 18-52]). The mean follow-up time was 3.4 (range, 2.2-4.8) and 3.8 (range, 2.1-5.6) years in the SD and control group, respectively. During the follow-up period, 4 of 9 (44.4%) patients with an SD (50% Shoulders) had a recurrent seizure postoperatively. Of those 4 patients, three sustained a recurrent dislocation of the operative Shoulder(s) resulting from a postoperative seizure, including one who dislocated bilateral Shoulders from a single seizure event after bilateral Latarjet procedures. There was no recurrent instability in patients who did not sustain a seizure in the postoperative period. Having a seizure in the postoperative period significantly increased the risk of recurrent dislocation (OR = 39.9, P = 0.04). Conclusions Latarjet is a successful operation for recurrent Anterior Shoulder instability in patients without an SD. While it can still be successful in patients with SD, adequate control of seizures postoperatively is paramount to prevent recurrent instability episodes. Patients with an SD can be advised that if their seizures can remain controlled, they have a high likelihood of clinical success equal to that of patients without an SD.
