Fracture of the Capitulum humeri is rare, and opinions on the preferred surgical management of this injury differ. We studied 12 patients who underwent surgical treatment for fractures with a mean follow-up of 3 years (7 months to 10 years 3 months). In 11 cases, open reduction and internal fixation were performed, while in 1 case, the fracture fragment was removed. Kirschner wire and soft wire are used in our method for open reduction. Open reduction is stable and produces the best results, especially when performed immediately after the trauma. Early open reduction is thus recommended as the treatment for fracture of the capitulum humeri.
