Promising 8-year results seen with reverse shoulder arthroplasty prosthesis
Recently published results showed a survival rate of 97.4% at 8 years with a specific reverse shoulder arthroplasty prosthesis.
“In case of primary reversed shoulder arthroplasty, long-term results show a high survival rate of more than 95%,” Alexander Van Tongel, MD, PhD, and Lieven De Wilde MD, PhD, told Healio.com/Orthopedics.
Researchers identified 126 primary Delta Xtend prostheses (DePuy Synthes) implanted between October 2006 and December 2009. There was a follow-up of at least 8 years available for 74 patients. The mean follow-up was 113.1 months. Shoulder function and pain were evaluated with age- and sex-adjusted Constant-Murley scores.
Results showed the mean age- and sex-adjusted Constant-Murley score was 44.6% preoperatively and was 75.8% at 3 months postoperatively and was 91.1% at 5 years. The mean age- and sex-adjusted Constant-Murley score at the latest follow-up visit was 79.9%. This was significantly lower compared with the age- and sex-adjusted Constant-Murley score at 5 years postoperatively. At the 8-year follow-up, the overall survival rate was 97.4%. – by Monica Jaramillo
