Inferior glenoid baseplate tilt relative to the coronal axis of the scapular body has been associated with improved results and fewer postoperative complications in reverse shoulder arthroplasty. However, the native glenoid surface is not always a reliable reference for the true scapular axis. Digital preoperative planning software and advanced imaging now allow surgeons to more precisely deter...

BACKGROUND AND PURPOSE Alignment of the glenoid component with the scapula during total shoulder arthroplasty (TSA) is challenging due to glenoid erosion and lack of both bone stock and guiding landmarks. We determined the extent to which the implant position is governed by the preoperative erosion of the glenoid. Also, we investigated whether excessive erosion of the glenoid is associated with...

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...

The reverse shoulder arthroplasty in the conditions of modified anatomy glenoid is complex and often excludes possibility using standard tactics installing component. There are no identical glenoids, each articular cavity scapula differs height, width, angle inclination, density bone tissue, absence or presence various defects tissue. Given variety options for changing structure quality tissue ...

Loosening of the glenoid component is a frequent cause of failure of total shoulder arthroplasty (TSA). The etiology of glenoid component loosening is multifactorial and includes aseptic osteolysis, rotator cuff insufficiency, soft tissue instability, and infection. A loose glenoid component is frequently associated with a substantial loss of glenoid bone, which necessitates additional procedur...

Introduction: Glenoid version, glenoid surface orientation in the axial plane, has an important role in the passive stabilization of the articular components of the glenohumeral joint. Glenoid shape and version has been associated with glenohumeral instability, arthritis, and rotator cuff tears. Cross-sectional computed tomography (CT) and magnetic resonance (MR) imaging have been demonstrated ...

Temporomandibular joint morphogenesis was studied. Ranging in age of fetuses examined was from 6 to14 weeks' gestation. Our results showed the condyle so first element that appear between 6 degrees and 8 degrees week (condylar blastema). After a week appear temporal elements. Disk appear at the same time of glenoid blastema and it reaches an advanced differentation before of the condyle and tem...

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...
