Shoulder dislocations occur when the humeral head translates over the edge of the glenoid socket of the scapula, permanently stretching the capsular ligaments. This injury of the capsular tissue results in pathological joint laxity which is a major contributor to recurrent dislocations and is a key feature of shoulder instability. The ideal surgical parameters to correct this pathology have yet to be established due to a lack of understanding of how shoulder kinematics and capsular mechanics are affected by different surgical procedures. To address this knowledge gap, we developed patient-specific computer models of the shoulder which include anatomically accurate models of the capsule. The purpose of this study was to simulate capsular plication of the glenohumeral ligaments and to evaluate the effect different degrees of plication had on glenohumeral joint laxity and rotation.

Introduction: The treatment of chronic shoulder instability, associated with poor tissue quality, remains challenging in the setting of anterior capsular deficiency. There are a few viable alternatives in the end-stage shoulder instability when multiple surgical attempts to correct the pathology have failed. The purpose of the present paper is to demonstrate the efficacy of anterior capsular reconstruction with semitendinosus autograft for the management of capsulolabral deficiency without associated bone loss. Case Report: A 39-year-old female admitted in our institution with a history of recurrent atraumatic anterior dislocation of the left shoulder after three unsuccessful surgical attempts: Arthroscopic and open capsulorrhaphy and a Latarjet coracoid transfer. CT scan images showed adequate placement (flush) of the coracoid transfer without any sign of reabsorption. Reconstruction of anterior capsulolabral structure was performed using a Semitendinosus autograft. The middle and inferior glenohumeral ligaments, the more crucial ligaments for anterior-inferior shoulder stability, were effectively recreated. The patient did not suffer any recurrent dislocation or subjective symptoms of instability at the time of the final follow-up, 2 years after surgery, and the ASES score increased from 36 preoperatively to 86. Conclusion: This technique, described for the first time as a salvage procedure after Latarjet failure, could represent a safe and viable treatment option in the context of multiple ineffective surgeries. Keywords: Autograft, capsulolabral reconstruction, latarjet, recurrent shoulder instability.

Introduction: Bankart lesion is the anterior glenohumeral instability most common associated injury. Tears at glenohumeral ligaments can be intra substance or at humeral insertion, this location may be the cause of instability. Posterior humeral avulsion of the glenohumeral ligament (PHAGL) can be an isolated or associated cause of instability and it is usually related to the posterior glenohumeral instability. The aim of this article is to report the clinical assessment and postoperative outcomes of 6 patients with PHAGL with anterior shoulder instability. Materials and Methods: We evaluated six patients with PHAGL due to anterior glenohumeral instability arthroscopically repaired. All 6 patients developed the lesion after a sports-related trauma. Sixty six per cent of patients had associated intra-articular shoulder pathologies. The diagnosis with MRI arthrogram (with gadolinium) was performed preoperatively in 50% of patients. Postoperative evaluation was made with Rowe, ASES and WOSI scores. Results: All patients returned to their previous sports level. One patient had a recurrence. Postoperative scores results are WOSI: 13.13%, Rowe 83.33 and ASES 95.83. Discussion: Humeral avulsions of glenohumeral ligaments represent 25% of capsulolabral injuries. PHAGL injury was initially described as a cause of posterior instability, but according to two other series, our study shows that this lesion may also cause anterior instability. It is critical to have a high index of suspicion and make a correct arthroscopic examination to diagnose this injury, because arthroscopic repair of PHAGL has good postoperative outcomes.
