FRACTURES OF THE RADIAL HEAD TREATED BY INTERNAL-FIXATION - LATE RESULTS IN 26 CASES

Twenty-six patients, ranging in age from 14 to 57 years (average 29 ye ars), were evaluated an average of 7 years and 4 months (range 1-14 ye ars) after open reduction and internal fixation of a displaced radial head fracture. Using Mason's classification, there were 11 type II fra ctures, 9 type III fractures, and 6 type IV fractures with associated dislocation of the elbow. Seven patients had ipsilateral extremity inj uries that included fractures of the coronoid process, capitellum, hum erus, and distal radius. Using the Broberg and Morrey elbow score, goo d or excellent results were achieved in all Mason type II and type III fractures. Four of the six Mason type IV fractures were rated good or excellent. Fair results were obtained in two patients who had an asso ciated dislocation of the elbow and multiple ipsilateral extremity inj uries. In these two patients, secondary excision of the radial head re lieved pain and yielded some improvement in flexion and forearm rotati on.
