Surgical anatomy of bicipital branch of musculocutaneous nerve.

Twenty patients with brachial plexus injury have been treated with one fascicle nerve transfer to the bicipital branch of the musculocutaneous nerve for reconstruction of elbow flexion. The mean distance from the medial epicondyle to the origin of this branch is 17.9 centimeters. The correlation coefficient and test of statistic significance between distance and heights of patients is 0.76 and 5.07 respectively (t18, 0.995 = 2.88). There is no correlation between the arm span, weight, age and the distance.
