There was a patient with a defect of the median and ulnar nerves throughout the entire forearm. We used rotation of the segment of ulnar nerve from the shoulder to restore sensitivity along the palmar surface of the hand. Blood supply of this segment was achieved through the recurrent ulnar vessels. Proximal end of the ulnar nerve was dissected up to the armpit. Blood supply was preserved through a vascular arcade formed by superior collateral and recurrent ulnar vessels. Blood supply of the nerve was achieved through the recurrent ulnar vessels after ligation of superior collateral vessels. These vessels served as a «point of rotation» for ulnar nerve transposition on the forearm. Proximal stump of the median nerve was sutured with the transposed segment of the ulnar nerve within the ulnar fossa. At the level of the wrist joint, ulnar nerved was sutured with the distal stump of the median nerve and superficial branch of the ulnar nerve. The last one was dissected from the distal stump of the ulnar nerve. The length of the ulnar nerve segment used for repair was 28 cm. This method ensured favorable outcome with restoration of sensitivity on the palmar surface of all fingers of the hand (S2-S3) in two years after surgery.
