This is a retrospective analysis of 27 patients who were treated operatively for osteochondritis dissecans of the capitellum. All patients were male baseball players with the mean age of 13 years. The authors evaluated debridement in seven patients, fixation in 13 patients, and osteochondral autograft in seven patients.
The results indicated that arc of motion improved, as well as their subjective pain and function scores. The authors found that four of their patients who had defects in the lateral margin of the capitellum were unable to return to sport and had decreased motion.
The significance of the study is that it demonstrates the importance of reconstruction or maintaining the lateral margin of the capitellum in conjunction with treating this disorder. The indications for osteochondral grafting remain unclear at the present time.
