[Injuries of the medial epicondyle of the humerus in children. Conservative or surgical therapy?].

18 patients with avulsions of the medial epicondyle 1 10/12 to 16 2/12 years after trauma are presented. Non-union occurs very often after conservative treatment involving avulsion with or without displacement. Although non-union of the medial epicondyle gives no or only little disability, the fixation with one or two Kirschner wires is recommended to avoid non-union. Open reposition is necessary in cases with injury of the n. ulnaris and in cases with incarceration of the epicondyle in the elbow joint.
