Fracture-separation of the distal humeral epiphysis.

Sixteen patients were seen with fracture-separation of the distal humeral epiphysis. The difficulty that may be encountered in making the diagnosis is thought to be partly responsible for the relative paucity of previous reports of this condition. All sixteen patients revealed posteromedial displacement of the distal humeral epiphysis on the initial roentgenogram. Child-abuse was documented or suspected as a cause in six of the sixteen fractures. Treatment consisted of closed reduction and immobilization with the elbow in 90 degrees of flexion and the forearm pronated, for three weeks. Post-injury cubitus varus, which developed in three patients and was thought to be due to inadequate reduction, did not progress.
