Radial nerve lesion after medial epicondyle osteosynthesis in a pediatric patient: A rare complication of surgery.

Fractures of the medial epicondyle are relatively common in children and may be associated with nerve lesion, especially in case of displacement. Incarceration of the ulnar nerve in the fracture site is feared in Watson-Jones stage II, rarely directly related to osteosynthesis. Depending on the degree of fracture displacement, various osteosynthesis techniques may be used; nerve injuries are a rare but known complication of these procedures. We report a case of radial nerve injury related to pinning osteosynthesis of a medial epicondyle fracture.
