Transposition of the bicipital tuberosity for treatment of fixed supination contracture in obstetric brachial plexus lesions.
In nine patients with obstetric brachial plexus lesions (Klumpke type), an impingement of the bicipital tuberosity on the ulna was the main cause for the forearm and hand to be fixed in supination. A surgical technique using reinsertion of the biceps tendon on the bicipital tuberosity is described in detail. It has substantially improved all patients. After a mean follow-up of 29.4 months the hand was in a more functional position than preoperatively in all patients. In seven cases pronation could be increased by contraction of the biceps muscle. By relaxing the biceps muscle and by contraction of the supinator muscle a limited active supination was possible in six cases.
