BACKGROUND Although increased retroversion of the glenoid has been shown to be an important factor in posterior instability of the shoulder, there are few studies reporting glenoid bone structure as a risk factor in anterior dislocation of the shoulder. This study aimed to compare glenoid version in patients with anterior dislocation of the shoulder and individuals in a control group with no sh...

Background: In shoulders requiring arthroplasty, the extant glenoid may provide insufficient intrinsic stability for the humeral head – for example if the glenoid is flat or biconcave. In such cases the surgeon can restore the desired intrinsic stability using a glenoid prosthesis with a known surface geometry. Alternatively, the surgeon can modify the surface of the glenoid to a geometry that ...

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...

Background: Recurrent Anterior Shoulder Instability (RASI) is usually preceded by trauma. The incidence recurrence rate high in trauma Induced RASI, especially younger patients. right diagnosis and management must be ruled out immediately for a better outcome. Case Report: 28-year-old man complained of shoulder instability the past eight years, which worsened last year. patient had history appr...

The scapula connects the arm with the chest wall and is therefore of great importance for a free range of shoulder of motion. For a long-term scapular fractures had been treated predominantly conservative. However, clinical studies of the past decades revealed that some fracture patterns deserve operative treatment to prevent unfavorable functional outcome and chronic state of pain. Scapular fr...

BACKGROUND Reverse shoulder prostheses are increasingly used in recent years for treatment of glenohumeral arthropathy with deficient rotator cuff. Bone preservation is becoming a major goal in shoulder replacement surgery. Metaphyseal humeral components without a stem were developed to minimize bone resection and preserve bone. This study evaluated the clinical and radiologic outcomes at 2 to ...

  Background: Open Bankart surgery is the main treatment procedure in patients with recurrent anterior shoulder dislocation, especially in cases with glenoid bone defect. The goal of this study was to determine the outcomes after open Bankart surgery in cases of recurrent anterior shoulder dislocation with glenoid bone defects and concomitant Hill-Sachs lesions. Methods: Between 2006 and 2010,...

Glenoid rim fractures, accompanied by acute glenohumeral dislocation or subluxation usually results in persistent instability. Traditionally open reduction and internal fixation has been recommended in displaced intra-articular glenoid fractures. However, open reduction is difficult, and it may not be possible to address the associated intra-articular soft-tissue injuries. A few reports of arth...

INTRODUCTION Intra-articular glenoid fractures are extremely rare and may be associated with other injuries. Traditionally open reduction and internal fixation has been recommended in displaced intra-articular glenoid fractures. However open reduction is difficult and it may not be possible to address the associated intra-articular soft tissue injuries. A few reports of arthroscopic assisted fi...

The purpose of this study was to compare differences in wear performance of conforming and nonconforming glenoid designs, using clinical, radiographic, and retrieved polyethylene glenoid component outcome Sixty-three glenoids met the study criteria, and each glenoid was assigned to the conforming group (if the radii of curvature of the humeral and glenoid components were identical) or the nonco...
