Radial head arthroplasty in mason type 3 and 4 radial head fractures: Functional efficacy and complications

Background: Radial head arthroplasty (RHA) is a best alternative to radial head excision in Mason III and IV fractures. The purpose of this study was to assess the outcomes of RHAs in terms of the range of movement and elbow stability using the Mayo elbow performance score (MEPS).Methods: A prospective and interventional study included 25 patients were performed RHAs. During follow up, patients were clinically and radiologically assessed and complications. Results: 92%of patients presented with excellent to good outcomes at 24 weeks (mean MEPS was 92.17±11).Conclusion: RHA is successfully performed in comminuted radial head fractures because of injury to lateral collateral complex and comminution.
