Shoulder arthroplasty in Olmsted County, Minnesota, 1976-2000: a population-based study.
Because little information is currently available on the epidemiology of shoulder arthroplasty, this study was designed to evaluate the characteristics of patients undergoing this procedure and changes in practice patterns. Residents of Olmsted County, Minnesota, who underwent shoulder arthroplasty between 1976 and 2000 were identified (98 residents, 112 procedures). A relatively lower initial rate of shoulder arthroplasty was followed by a statistically significant steady increase (P < .0001), with an age- and sex-adjusted annual operative incidence rate of 1.4 per 100,000 person-years (1976-1980) to 10.1 per 100,000 person-years (1996-2000). Increased utilization of shoulder arthroplasty during the last decade was mainly a result of its application in osteoarthritis. A significant need exists for examination of utilization patterns for shoulder arthroplasty. An aging population and an increased demand and awareness by the public regarding interventions to improve quality of life will shape the future of arthroplasty, reinforcing the need for future studies of this nature.
