【 摘 要 】

IntroductionPrimary reverse shoulder arthroplasty has been reported to provide good outcomes. The majority of designs utilize a large portion of the glenoid. Some studies have reported worrisome rates of notching and stress fractures of the acromion or scapular spine. The purpose of this study was to determine the outcome and complications of a bone-preserving reverse prosthesis with limited ingrowth glenoid surface paired with an onlay humeral component.Materials and methodsBetween 2014 and 2015, 96 reverse arthroplasties were implanted using a bone-preserving reverse with a 135° onlay humeral bearing. Six patients died. The remaining 87 patients (90 shoulders) were followed for 2 years or until revision. Mean age was 69.3 years. The underlying diagnosis was cuff tear arthropathy (13), irreparable cuff tear (39), osteoarthritis (32), and other (6). Shoulders were followed for 2 years or until revision surgery.ResultsReverse shoulder arthroplasty resulted in significant improvements in pain, motion, and f...
