Surgical dissection of the medial aspect of the elbow. a Identification of the median nerve. b Identification of the most proximal (blue pin) and most distal (green pin) points of the ulnar insertion of the brachialis muscle and measurement of the “brachialis insertion length” with a graduated caliper. c Measurement of the shortest linear distance between the median nerve and the most proximal point of the distal end of the brachialis (blue pin) with a graduated caliper. d Measurement of the shortest linear distance between the median nerve and the most distal point of the distal end of the brachialis (green pin) with a graduated caliper. Ant. Anterior, Post. Posterior, Dist. distal, Prox. proximal
