OBJECTIVE The aim of this study was to assess the effects of coracoid bone block (modified Latarjet) procedure on clinical and functional results in cases with glenoid bone defect accompanied with anterior shoulder instability. METHODS The study included 35 patients (average age: 35 years; range: 20 to 58 years) with glenoid bone defect and recurrent dislocations treated with the modified Lat...

Glenohumeral bone defects are a common finding in shoulder instability and they are strongly correlated with recurrence of dislocation and failure following arthroscopic Bankart repair. Most authors agree that open surgery should be considered in the presence of certain conditions: glenoid bone loss > 25%, a lesion involving > 30% of the humeral head, an engaging Hill-Sachs lesion, bipolar bone...

Aseptic loosening of the glenoid component after total shoulder arthroplasty presents a considerable treatment challenge in the setting of substantial glenoid bone loss. Glenoid component explantation and bone grafting of defects have become common methods of recreating bone stock in hopes of preventing later fractures, maintaining joint kinematics, and allowing for later glenoid reimplantation...

2 Department of Orthopaedic Surgery, Harvard Medical School, Boston, MA Revision of the glenoid component in total shoulder arthroplasty (TSA) remains an unresolved problem. Even with meticulous surgical technique, available bone stock may preclude the implantation of a new glenoid component. Multiple studies have demonstrated that patients in whom a new glenoid can be placed have improved pain...

Introduction Glenoid prosthesis loosening is a major complication of shoulder arthoplasty, thus highlighting the importance of improving glenoid prostheses longevity [1]. Finite element (FE) stress analyses have been used to assist joint prosthesis designs. Prior FE analyses have employed static or non-linear solutions to compare design variations with respect to stresses in the glenoid bone an...

Severe glenoid wear is technically problematic, has a higher complication rate, and inferior results in the setting of shoulder arthroplasty. This paper introduces four basic strategies for treating glenoid erosion with a reverse shoulder arthroplasty which include; 1. eccentric reaming, 2. bone grafting of glenoid, 3. reaming and bone grafting, and 4. using augmented baseplates. The benefits a...

Glenohumeral osteoarthritis is the most common reason for shoulder replacement. Total shoulder arthroplasty provides reliable pain relief and restoration of function, with implant survivorship reported at 85% at 15 years. Glenoid component wear and aseptic loosening are among the most common reasons for revision. Glenoid wear characteristics have been correlated with, among other things, the de...
