[Fractures of internal epicondyle of the humerus with intra-articular incarceration of bone fragments].

The article analyses 41 fractures of the medral epicondyle of the humerus in children with incarceration of the fragment in the cavity of the elbow joint. The clinical and X-ray signs of this complication are described in detail. Open reduction is the optimal method of treatment. During the operation the ulnar nerve is examined, the cavity of the elbow joint is cleaned, and stable osteosynthesis of the medial epicondyle is performed. Restorative treatment can be started in the early postoperative period if a screw-awl has been applied. The function of the elbow joint is restored completely in 6 to 8 weeks in fresh cases, but in delayed treatment and neglected cases rehabilitation takes 6 months or longer.
