BACKGROUND Reverse total shoulder arthroplasty is the accepted method of treatment for selected shoulder disorders. The purpose of this study was to compare primary reverse shoulder arthroplasty surgical techniques as well as clinical and radiographic outcomes in patients with acquired glenoid bone defects and in those with normal glenoid morphology. METHODS Preoperative three-dimensional com...

BACKGROUND Anterior shoulder dislocation is common. The treatment of recurrence with glenoid bone defect is still considered controversial. A new arthroscopic subscapularis augmentation has recently been described that functions to decrease the anterior translation of the humeral head. The purpose of the presented study was to examine the biomechanical effect on glenohumeral joint motion and st...

BACKGROUND The optimal treatment of Hill-Sachs injuries is difficult to determine and is potentiated by the finding that a Hill-Sachs injury becomes more important in the setting of glenoid bone loss, making engagement of the humeral head on the glenoid inherently easier. The "glenoid track" concept was developed to biomechanically quantify the effects of a combined glenoid and humeral head bon...

Glenoid component failure is the most common complication of total shoulder arthroplasty. Glenoid components fail as a result of their inability to replicate essential properties of the normal glenoid articular surface to achieve durable fixation to the underlying bone, to withstand repeated eccentric loads and glenohumeral translation, and to resist wear and deformation. The possibility of gle...

BACKGROUND Glenoid bone damages consisting of anterior rim erosion and bony avulsion are very important in decision making for treatment of recurrent dislocation in shoulder joint. This study was aimed to determine the prevalence of these damages in patients with anterior recurrent shoulder dislocation. METHODS The study was a cross-sectional study evaluating patients with unstable shoulder j...

The effect of different methods of preparation of glenoid bone on displacement and deformation of a glenoid component under eccentric loading was investigated in a series of scapulae of cadavera. Handburring of the osseous surface was associated with less displacement and deformation than simple removal of cartilage with a curet. Reaming resulted in the least displacement and deformation. Subst...

INTRODUCTION Glenoid bone grafting is often used in cases of reverse shoulder arthroplasty (RSA) with glenoid deficiency. Additionally, bony increased-offset RSA (BIO-RSA) uses a cylindrical bonegraft harvested from the humeral head and is positioned beneath the glenoid baseplate to increase lateralization. Postoperative computed tomography (CT) has been used to detect glenoid bonegraft resorpt...

Glenoid morphology has an important impact on outcomes and complication rates after shoulder arthroplasty for primary glenohumeral arthritis. The B2 glenoid, or a biconcave glenoid with posterior humeral head subluxation, in particular has been associated with a poorer outcome with shoulder arthroplasty compared with other glenoid types. A variety of techniques may be used to address the bone d...

Anterior glenoid bone loss is present in nearly all cases of recurrent anterior glenohumeral instability. Treating glenoid bone loss in the setting of recurrent instability is challenging, and often, soft tissue stabilization procedures in isolation are inadequate. The nonanatomic, incongruous joint resulting from most bony augmentation procedures has motivated investigators to find an alternat...

Osteochondral disease of the glenoid is a well-known cause of shoulder pain and disability in young and active patients. The etiology can be multifactorial, and disease severity can exist across a wide spectrum. Symptoms can often interfere with athletic performance, job responsibilities, and activities of daily living. Although a number of cartilage restoration techniques exist for other joint...
