Fracture epiphyseal separation of the distal humerus.

Seven patients seen with fracture separation of the distal humerus epiphysis have been analysed for the problems linked with the radiological diagnosis of this injury. Peculiar male predominance, exclusive left-side involvement, consistent postero-medial displacement of the epiphyseal fragment and ability to achieve near anatomic reduction by closed manipulation in fresh cases have been some of the other features observed. The literature has been briefly reviewed for this infrequent and usually misdiagnosed injury.
