Result of a pyrocarbon prosthesis after comminuted and unreconstructable radial head fractures.

Abstract

The purpose of this study is to analyze the results of treating unreconstructable acute radial head fractures associated with other elbow fractures and soft-tissue injuries with a pyrocarbon radial head prosthesis replacement, as well as repair of the associated injuries. Twenty-eight patients with Mason type III unreconstructable and unstable radial head fractures and with associated injuries (according to Hotchkiss classification modified by van Riet) were treated with a pyrocarbon radial head prosthesis replacement; repair of collateral ligaments and associated elbow fractures was also carried out. Patients were evaluated in accordance with the Mayo Elbow Performance Score, measuring pain, grip strength, range of motion, and stability, as well as radiographic images. After a mean of 32 months postoperatively (range, 12-62 months), the mean Mayo Elbow Performance Score was 92 points. The result was considered excellent or good in 25 patients, with a high degree of satisfaction and functional restoration. The results of treating Mason type III radial head fractures with additional elbow fractures and soft-tissue injuries with pyrocarbon radial head prostheses are satisfactory; nevertheless, long-term follow-up is still necessary.
