A 20-year-old woman presented 6 months after an initial injury to her left elbow with pain and restricted movements. She was diagnosed with a type I malunited (Hahn-Steinthal) type of capitellum fracture through radiographic studies. Classically, the treatment has been excision of the fragment, which carries a risk of valgus instability of the elbow and late osteoarthrosis. We report a case of malunited type I capitellum fracture, for which corrective osteotomy through fracture site, open reduction and internal fixation was done 6 months following missed trauma. At 24 months follow-up the capitellum fracture had united and the patient has a stable elbow and excellent range of motion. Our case demonstrates that for type I malunited capitellum fractures corrective osteotomy through fracture site and internal fixation rather than excision of the fragment in young can result in successful union and stable elbow.
