The rising number of morbidly obese patients may have significant consequences on the health care system. It may alter the effectiveness, safety as well as cost of certain surgical procedures. Reverse shoulder arthroplasty (RSA) is rapidly gaining in popularity. We investigated the effect of morbid obesity on outcomes, complications, disposition and cost in morbidly obese patients undergoing RSA in a 1: 3 case control series. Our joint registry was searched for all patients undergoing primary RSA (excluding fractures) with a minimum of 24 months follow-up from 2003–2010; 21 patients with Body Mass Index (BMI) > 35 were identified (follow-up 45 ± 16 months, 17 females and 4 males, age 69 ± 7) and compared to 63 matched control patients with BMI<30 (follow-up 48 ± 20, 50 females, age 71 ± 6). Outcome data was obtained pre- and postoperatively. Patients' Charlson-Deyo comorbidity index (CDI), total comorbidities, operative time, blood loss (EBL), hospitalization length, disposition, cost and complications were recorded.Background:
