Radiologic Comparison of Humeral Position according to the Implant Designs Following Reverse Shoulder Arthroplasty: Analysis between Medial Glenoid/Medial Humerus, Lateral Glenoid/Medial Humerus, and Medial Glenoid/Lateral Humerus Designs

Humeral Head Replacement and Reverse Shoulder Arthroplasty for the Treatment of Proximal Humerus Fracturesm

Acute proximal humeral fractures in the elderly are generally treated non-operatively if alignment is acceptable and in stable fracture patterns. When operative treatment is indicated, surgical fixation is often difficult or impossible to obtain. Hemiarthroplasty has long been the standard of care. However, with its reliance on tuberosity healing, functional outcomes and patient satisfaction ar...

Reverse Total Shoulder Arthroplasty in Proximal Humerus Fractures

Early Versus Late Reverse Shoulder Arthroplasty for Proximal Humerus Fractures: Does It Matter?

Background: This study compared the outcomes between patients with proximal humerus fractures (PHF) whounderwent acute reverse total shoulder arthroplasty (RSA) to those who underwent an alternative initial treatmentbefore requiring (secondary) RSA.Methods: Patients who underwent RSA after suffering a PHF were identified. Two year clinical follow-up was requiredfor inclusion. Patients were divi...

Solitary Plasmacytoma of the Humerus

Geometric Analysis of the Proximal Humerus in Elderly Japanese Patients: Implications for Implant Selection in Reverse Shoulder Arthroplasty.

The implants used in reverse shoulder arthroplasty were originally designed for white patients; thus, they might not be optimal for smaller Asian patients. The selection of reverse shoulder arthroplasty systems is limited in Japan. The purpose of this study was to measure the geometry of the proximal humerus in elderly Japanese patients to inform implant selection according to humerus size. Thi...
