1. In cases of fracture of the medial epicondyle with displacement into the elbow joint, diagnosis often rests mainly on the roentgenogram. A satisfactory anteroposterior view may be difficult to obtain, but if, in the lateral roentgenogram alone, the epicondyle can be seen at the joint level, it may be regarded as being in the joint.
2. Reduction in early cases can easily be accomplished by anaesthetizing the patient, gently abducting the forearm on the humerus, and applying faradism to the flexor muscles.
3. Cases unrecognized for more than a few weeks are probably best left alone and not subjected to operative reduction.
4. Immediate anterior transposition of the ulnar nerve is unnecessary.
