Triceps to biceps transfer to restore elbow flexion in three patients with brachial plexus palsy.

Abstract

Between April 1994 and April 1998, triceps to biceps transfers were done for three men with post-traumatic lesions of the brachial plexus and consequent loss of elbow flexion. Their mean age at the time of their accidents was 33 years (range 19-41) and at the time of muscle transfer 40 years (28-46), with a mean observation period of 21 months (12-31). The transfer resulted in active elbow flexion in all patients with a mean of 113 degrees (90 degrees-130 degrees) and a degree of strength 4-5 (contraction against resistance) with no remaining deficit of passive extension. Two patients were satisfied with the result of the operation and the other was content. No complications were noted. The transfer of the triceps muscle to the tendon of the biceps muscle on loss of elbow flexion resulted in adequate movement and degree of strength. The triceps to biceps transfer involves operating close to the elbow joint and minimal complications, is cosmetically satisfactory, and is particularly suitable for co-contraction of triceps and biceps.
