It is uncommon that the fractured fragment is interposed into the ulno-humeral joint after closed reduction of dislocation of the elbow with medial humeral epicondyle in children, although interposition of medial humeral condyle which hinder the reduction is thought to be extremely rare. We experienced such a case.
A boy aged thirteen was admitted to our hospital immediately after injury. He was diagnosed as traumatic dislocation of the elbow with fracture of the medial humeral epicondyle. Closed reduction was carried out unsatisfactorily, because of interposition of the fragment into the ulno-humeral joint. Open reduction was carried out and it was revealed that the fragment was not the humeral epicondyle, but the medial humeral condyle. Reduction and internal fixation was done. Three months after the operation functional recovery is still poor and X-ray showed marked changes of trochlear epiphysis. He is receiving the rehabilitation.
