Abstract

BACKGROUND: Metallic humeral and glenoid lateralized implants have been developed to prevent common problems that can emerge using Grammont’s concept (ie, medialization of center of rotation, decreased humeral offset, scapular notching) in reverse shoulder arthroplasty. The purpose of this study was to evaluate the clinical and radiological results of metallic humeral and glenoid lateralized implants for cuff tear arthropathy (CTA) and primary osteoarthritis (OA). METHODS: In this prospective study, patients with CTA or OA who underwent reverse shoulder arthroplasty using augmented base plates for glenoid lateralization and a “curved stem” design for the humeral side were included. The Constant-Murley score and Subjective Shoulder Value were documented at 1- and 2-year follow-ups. Radiographs were reviewed for scapular notching, instability, loosening, osteolysis, ossification, bone resorption, or fractures. Lateralization and distalization shoulder angles were evaluated at the final follow-up. RESULTS: There were 23 patients with CTA and 19 patients with OA (27 women; mean age, 76 years; range, 59-85) available for examination at 2 years. Both groups increased significantly in all outcome measures compared with baseline (P
