Background Arthroscopy has rapidly transformed the treatment of anterior shoulder instability over the past 30 years. Development of arthroscopic equipment has permitted the investigation and diagnosis of the unstable shoulder, and fixation methods have evolved to promote arthroscopy from an experimental procedure to one of first-line mainstream treatment. Methods Key research papers were rev...

BACKGROUND A Hill-Sachs lesion of the humeral head after a shoulder dislocation is clinically insignificant in most cases. However, a sizable defect will engage with the anterior rim of the glenoid and cause instability even after anterior glenoid reconstruction. The purpose of this study was to evaluate the outcome of arthroscopic capsulotenodesis of the posterior capsule and infraspinatus ten...

BACKGROUND The Oxford Shoulder Instability Score (OSIS) is a short, self-reported outcome measurement for patients with shoulder instability. In this study, the OSIS was validated in Dutch by testing the internal consistency, reliability, measurement error, validity and the floor and ceiling effects, and its smallest detectable change (SDC) was calculated. METHODS A total of 138 patients were...

ABSTRACT We present a case of shoulder instability following a traffic accident. Allman Type I midshaft clavicle, Ideberg Type II glenoid and DeCloux Type I scapular body fractures were diagnosed following radiologic examination. There were no signs of ligamentous injury. Mechanical instability was noted at the shoulder due to breakage of the supportive bony skeleton. The patient was treated su...

Background The clinical evaluation of the patient with shoulder instability can be challenging. The pathological spectrum ranges from the straightforward "recurrent anterior dislocation" patient to the overhead athlete with a painful shoulder but not clear instability episodes. Advances in shoulder arthroscopy and imaging have helped in understanding the anatomy and physiopathology of the sympt...

simultaneous dislocation of shoulder and humeral shaft fracture is a rare injury, and there is no clear protocol for its treatment. herein we present a case of a 15-year-old boy, who suffered from a job-related accident and sustained fracture of humeral shaft associated with ipsilateral anterior shoulder dislocation and fracture of greater tuberosity 15 years ago. he received closed reduction o...

BACKGROUND Post-traumatic anterior shoulder instability patients may present histopathologic lesions within the subscapularis muscle compatible with a scarring process associated with disuse atrophy. We hypothesized that such lesions identified on intraoperative biopsy at the time of primary anterior shoulder stabilization would predict a higher risk of postoperative instability recurrence. M...

PURPOSE athletes affected by shoulder instability cannot be judged solely according to the criteria used for non-athletes. In order to improve the assessment of shoulder instability surgery outcomes, the SPORTS score was tested in a cohort of athletes. METHODS ninety-eight athletes at an average follow-up of 4.6 years (range 1-9.2) after open or arthroscopic surgery for recurrent anterior sho...

PURPOSE The purpose of this study was to analyze results of arthroscopic stabilization with labral repair in a subset of patients with multidirectional shoulder instability and frank labral tear. METHODS A review of 13 patients (10 male and 3 female; mean age, 27.2 years) with multidirectional instability involving a labral tear of 270 degrees or greater requiring arthroscopic labral repair w...

The association between shoulder instability and the development of glenohumeral osteoarthritis has not been well studied in the literature. It is clear that some degree of chondral damage is associated with instability, and there appears to be an increased risk of developing symptomatic osteoarthritis and ultimately requiring a shoulder arthroplasty in patients with a history of instability. M...
