Resection of the radial capitellum. Long-term results

The results of 39 resections of the radial capitellum reviewed after an average of 12 years were excellent or good in 59% of the cases and fair or poor in 41%. The results were better in isolated fractures of the capitellum (excellent or good, 71%) compared with those with associated lesions in the same limb (excellent or good, 44%). A reduction of movement was frequently observed, particularly in pronation and supination, which was limited in 28% of the cases and abolished in 15%. In 4 patients there was a significant increase in cubitus valgus. Arthrosis was present in 45% and periarticular calcification in 74% of the cases. There were 5 cases of radioulnar synostosis and 4 cases of myositis ossificans. Subluxation of the distal radioulnar joint was observed in 26 wrists, 4 of which were painful. The results of resection of isolated fractures may be considered acceptable, while the prognosis of fractures with associated lesions is more unfavourable.
