Objective To evaluate the clinical efficacy of radial head prosthesis replacement in treatment of comminuted fracture of the radial head and discuss relative operative announcements. Methods There were 27 patients with comminuted fracture of the radial head who were treated with radial head prosthesis replacement. Results Of all, 26 patients were followed up for averaged 14 months. According to Broberg score, the post-operative function was excellent in 9 patients （35%）, good in 13 （50%） and fair in 4 （15% ）, with no poor results and with excellence rate of 85 %. Conclusion Radial head prosthesis replacement can better restore the stability, flexion and extension of the elbow as well as the rotational motion of the forearm and is worthy of clinical application.
