Superior ulnar collateral artery: This artery arises from the brachial artery near the middle of the arm and travels with the ulnar nerve toward the humerus. It anastomoses with the posterior branch of the ulnar recurrent artery and the inferior ulnar collateral artery which participate in the elbow anastomoses.

The operation was carried out as a two-stage procedure performed under general anesthesia without the use of muscle relaxants. In the first stage, the arms, shoulders, neck, and chest were prepared with the patient supine. The injured arm was positioned on an arm table. This allowed the exploration of the contralateral uninjured brachial plexus, and the harvesting of the pedicled ulnar nerve graft from the injured arm. Details of the surgical techniques involved in the exposure, confirmation, and division of the cC7 root have been described previously.9,10 The ipsilateral ulnar nerve was dissected proximally to the level of the superior ulnar collateral artery with its dorsal cutaneous branch straight after the isolation and transection at the level of the wrist. The MACN was identified by exposing the basilic vein and traced proximally from the same incision where the ulnar nerve was exposed close to the antecubital fossa. The distal ends of the anterior and posterior branches were transected at the area about 4 cm distal to the elbow (Figure 1(A)).11 The MACN was dissected proximally to the same level of the ulnar nerve (the superior ulnar collateral artery), and passed across the chest to the contralateral side with the ulnar nerve through a subcutaneous tunnel (Figure 1(B,C)). The incision was prolonged to the axilla in some patients, and the MACN was isolated proximally until the length was appropriate for tension-free repair. By using 8–0 sutures under 2.5 × magnification, the end of the MACN was sutured via an end-to-end and tension-free coaptation to the anterolateral portion of the anterior division of the cC7 nerve root. The distal end of the ulnar nerve was sutured to the posterior division of cC7 with its dorsal cutaneous branch suturing to the rest of the anterior division (Figures 1(D) and 2).
