Description
Summary:Background Obesity is a risk factor for worse outcomes in anatomic shoulder arthroplasty. The purpose of this investigation was to determine outcomes of primary reverse shoulder arthroplasty (RSA) in patients with morbid obesity. Methods We reviewed all primary RSAs performed on morbidly obese (body mass index [BMI] ≥40 kg/m2 ) patients from 2005 to 2012 at our institution with at least 2 years of follow-up. The study included 41 patients (57% female), the mean BMI was 44 kg/m2 , and the mean age was 67.7 years. Results The only intraoperative complication was an inferior glenoid fracture that remained stable after glenosphere implantation. At a mean follow-up of 3.2 years (range 2-7.36 years), 2 patients (5%) required revision surgery for infection (n = 1) and humeral loosening (n = 1). Survival was 98% at 2 years and 92% at 5 years. Additional postoperative complications included ulnar neuropathy (n = 1) and heterotopic ossification (n = 2). Pain relief was excellent, with 93% reporting moderate or severe pain preoperatively compared with 2% postoperatively ( P
