PURPOSE: To compare bipolar bone loss by evaluating the degree of glenoid bone loss, Hill-Sachs lesion size, and glenoid track in adolescents and adults with shoulder dislocations. METHODS: We performed a retrospective review between 2012 and 2016 of surgical and nonsurgical patients with a history of anterior shoulder dislocations (primary or recurrent) who underwent magnetic resonance imaging of the affected shoulder. The exclusion criteria included multidirectional instability, prior surgery, and posterior dislocation...

BACKGROUND: Recurrent glenohumeral anterior instability (RGAI) frequently induces combined glenoid and Hill-Sachs bone lesions and is a risk factor for soft tissue repair failure. This cohort study describes a simple preoperative quantification method for bone loss, the Clock method, the first that combines glenoid and humeral lesions. METHODS: Computed tomography scans of 34 shoulders with RGAI were twice reviewed by three independent observers, who measured bone lesions using the new Clock method and existing validated methods...

Glenoid bone loss presents a major risk for glenohumeral instability that has been well recognized as a cause of instability recurrence after attempted Bankart repair, and although most surgeons consider the Latarjet procedure as the gold standard, failures can occur with this technique as well and the search for alternative grafts to address glenoid bone loss is a major topic of ongoing research in the field. Of these techniques, the distal tibia allograft (DTA) has been shown to provide an excellent option to restore glenoid biomechanics, due to its congruency with the humeral head, dense bony quality, and the facility of harvest...

INTRODUCTION: Coracoid fractures are often missed since the fracture is not visualized in a routine anteroposterior view of the shoulder and special views are not ordered. Shoulder dislocation is common but it is rare to have a dislocation with a coracoid fracture. The purpose of this paper is to present the rare occurrence of bilateral coracoid fractures in a patient with unilateral anterior shoulder instability managed using the same fractured coracoid fragment by the latarjet procedure...

BACKGROUND: Glenoid bone loss in recurrent anterior shoulder instability is a challenging problem for shoulder surgeons, and knowledge about the anatomy of glenoid deficits is scarce. In this study, we tried to evaluate the pattern of this pathology. METHODS: Our analysis included 44 shoulders from 44 patients with recurrent anterior shoulder instability accompanied by a clinically relevant glenoid bone loss. The defect size, the localization of the inferior defect edge, and the defect angle were measured, and osseous landmarks were identified...

Complex glenoid deformities present the most difficult challenges in shoulder arthroplasty. These deformities may be caused by severe degenerative or congenital deformity, posttraumatic anatomy, tumor, or, in most cases, bone loss after glenoid failure in anatomical total shoulder arthroplasty. Methods of treating severe bone loss have included inlay and onlay bone-graft options with augmented fixation and, in severe cases, salvage hemiarthroplasty with limited goal expectations. Unfortunately, none of these methods has provided consistently satisfactory reproducible results...

BACKGROUND: Anterior shoulder instability has been successfully managed arthroscopically over the past two decades with refined "anatomic" reconstruction procedures involving the use of anchors for the repositioning and re-tensioning of the antero-inferior capsuloligamentous complex, in an effort to recreate its "bumper effect". METHODS: Research and online content related to arthroscopic treatment of shoulder instability was reviewed and their results compared...

BACKGROUND: Generally, a glenoid bone loss greater than 20% to 25% is considered critical for poor surgical outcomes after a soft tissue repair. However, recent studies have suggested that the critical value should be lower. PURPOSE: To determine the critical value of anterior glenoid bone loss that led to surgical failure in patients with anterior shoulder instability. STUDY DESIGN: Case-control study; Level of evidence, 3. METHODS: The study included 169 patients with anterior glenoid erosion...

PURPOSE: Latarjet, which is a coracoid bone block procedure, is an effective treatment for anterior shoulder instability with glenoid bone loss. During this reconstructive procedure the subscapularis may be tenotomized or be split to expose the glenoid neck. The aim of this study was to assess the effect of subscapularis management on functional outcomes and internal and external rotation durability and strength. Hypothesis is that the subscapularis split approach will result in better functional results and superior internal rotation strength and endurance...

An osseous Bankart lesion is commonly seen in patients with an anterior shoulder dislocation. It is defined as a detachment of the anteroinferior labrum associated with a glenoid rim fracture. Radiological studies are crucial not only for detecting glenoid bone defects but also for measuring the amount of bone loss. The precise quantification of the bony defect is crucial for the therapeutic desicion-making and clinical outcomes. Although we know that major glenoid bone loss requires surgical intervention, none of the studies performed so far answered the question what size of the defect should be an indication for open surgery procedures...

Bipolar bone loss in patients with anterior glenohumeral instability is challenging to treat. The goal of the treatment is to restore stability by ensuring that the humeral head remains within the glenoid vault. This can be achieved either with the combination of an arthroscopic Bankart procedure and remplissage (glenoid bone loss <25%), or with a Latarjet procedure (glenoid bone loss >25%). In cases with more severe bipolar bone loss of both the glenoid and the humeral head, the conventional approach has been to lengthen the articular arc of the glenoid and to ignore the Hill-Sachs lesion...
