Background Reverse total shoulder arthroplasty is an increasingly utilized treatment option for glenohumeral arthritis with massive, irreparable rotator cuff disruption associated with loss of glenohumeral stability and function. Several reverse shoulder implant designs from different manufacturers have been introduced to the market in recent years. Fixation of the glenoid base plate has been s...

INTRODUCTION Glenohumeral stability, defined as humeral head translations, is a key point after shoulder arthroplasty. Indeed this parameter is one of the determining factors in the glenoid loosening since linked with the rocking horse effect [1]. In an intact shoulder, translations are controled by all active and passive elements, especially the labrum [2]. In a prosthetic shoulder, translatio...

Glenoid replacement is technically challenging. Removal of a cemented glenoid component often results in a large osseous defect which makes the immediate introduction of a revision prosthesis almost impossible. We describe a two-stage revision procedure using a reversed shoulder prosthesis. Freeze-dried allograft with platelet-derived growth factor was used to fill the glenoid defect. Radiologi...

BACKGROUND Recurrent shoulder instability is commonly associated with glenoid bone defects. Coracoid transfer procedures, such as the Bristow and Latarjet procedures, are frequently used to address these bone deficiencies. Despite the frequent synonymous labeling of these transfers as the "Bristow-Latarjet" procedure, their true equivalence has not been demonstrated. Therefore, our purpose was ...

BACKGROUND Representing 3%-5% of shoulder girdle injuries scapula fractures are rare. Furthermore, approximately 1% of scapula fractures are intraarticularfractures of the glenoid fossa. Because of uncertain fracture morphology and limited experience, the treatment of glenoid fossa fractures is difficult. The glenoid fracture classification by Ideberg (1984) and Euler (1996) is still commonly u...

BACKGROUND Posttraumatic anterior shoulder instability is associated with anterior glenoid bone loss, contributing to recurrence. Accurate preoperative quantification of bone loss is paramount to avoid failure of a soft tissue stabilization procedure as bone reconstruction is recommended for glenoid defects greater than 20% to 27%. QUESTIONS/PURPOSES We determined whether radiography, MRI, or...

Objectives: Limited studies have compared graft-glenoid apposition and glenoid augmentation area between the latarjet distal clavicle grafts in glenohumeral stabilization. Additionally, pre-operative planning is typically performed using computerized tomography (CT), few used 3- dimensional magnetic resonance imaging (3D-MRI) reformations to assess graft dimensions. The purpose of study was two...

BACKGROUND The purpose of this study was to evaluate the angle between the long head of the biceps tendon (LHBT) and the glenoid during arthroscopic surgery and its correlation with biceps subluxation on magnetic resonance imaging (MRI). Furthermore, we evaluated the relationship of this angle with subscapularis tears and biceps pathologies. METHODS MRI and arthroscopic images of 270 consecut...

HYPOTHESIS Anterior instability is one of the most common complications in reverse shoulder replacement. This study hypothesized that intrinsic stability of a reverse prosthesis varies with the degree of version of the humerus and glenoid components. This should provide guidelines on how to best position the implant components to decrease the rate of dislocation. MATERIALS AND METHODS Resista...
