We have analysed 10 cases of capitellum fractures, which had been treated by excision or open reduction and internal fixation. The results were as follows : the final results of excision were generally better than those cases of open reduction and internal fixation, but open reduction could also be indicated if the capitellar fragment was large enough to be fixated ; a relatively prolonged period of physiotherapy of the injured elbow was usually needed, because the restoration of useful range of motion was frequently delayed.
