Objectives: To investigate long-term effects and complication rates after Coonrad-Morrey semi-constrained total elbow replacement. Methods: Retrospective analysis of consecutive Coonrad-Morrey total elbow arthroplasties performed in 1995-2006. Results: The mean Mayo elbow score was 47.0 (SD 21.9) points preoperatively and 87.0 (SD 13.7) at the end of 16-year follow-up (p<0.001). The respective figures for mean pain in motion were 6.1 (SD 2.8) and 0.7 (SD 1.9) points (p<0.001). At the end of follow-up, the average extension lag was 30°, flexion 135°, pronation 67°, and supination was 74°. The complication rate was 19%. Conclusion: Semi-constrained linked Coonrad-Morrey total elbow arthroplasty displayed promising clinical results and a long-lasting satisfaction in the surgery results. In the 16year follow-up, there were 12 periprosthetic fractures and the overall complication rate was 19%.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
