AbstractThe treatment of comminuted fractures of the radial head with concomitant injuries of the ulnar complex by resection of the radial head usually does not provide satisfactory long-term results. Other than joint instability in the elbow and a limited range of motion, radius proximalisation in the sense of ulnocarpal impingement, osteoarthritis and pain in the elbow have been described. Between 1995 and 1997, 11 radial head prostheses were implanted in ten patients who had sustained a comminuted fracture of the radial head with concomitant injury to the ulnar complex. A follow-up survey was conducted with the patients on average 5 years after the injury. Eight patients with nine implants participated in the follow-up, one patient had died and another refused to participate but declared that he did not suffer from any impairment. According to the Morrey score, two of the results were found to be very good, five to be good, one to be fair and one to be poor. Despite the severe injuries sustained by the elbow, neither joint instability in the elbow nor proximalisation of the radius, cubitus valgus, ulnar nerve syndrome, nor loosening of the prosthesis were found in any of the patients. In the event of comminuted fractures of the radial head which are impossible to reconstruct by osteosynthesis and which occur with concomitant ulnar ligamentous or osseous injury, the implantation of a prosthesis is preferred over the resection of the head of the radius.
