Congenital bilateral absence of the elbow flexors.

In this case report, a patient with bilateral congenital absence of the elbow flexors is described, which has not been described previously. The usual methods of tendon transfers after brachial plexus injury were not possible in this case because there were no biceps muscle tendons to which to attach. The method of moving the origin of the common extensor tendon proximally to have it function as an elbow flexor was successful and the patient obtained functional elbow flexion strength.
