【 摘 要 】

OBJECTIVE: To demonstrate the results of a double nerve transfer at the level of the hand for recovery of the motor and sensory function of the hand in cases of high ulnar nerve injuries. METHOD: Five patients underwent a transfer of the distal branch of the anterior interosseous nerve to the deep ulnar nerve, and an end-to-side suture of the superficial ulnar nerve to the third common palmar digital nerve. RESULTS: Two patients recovered strength M3 and three cases were graded as M4; recovery of protective sensation (S3+ in three patients and S4 in two) was observed in the fourth and fifth fingers, and at the hypothenar region. The monofilament test showed values of 3.61 or less in all cases and the two-point discrimination test demonstrated values of 7 mm in three cases and 5 mm in two. CONCLUSION: This technique of double nerve transfer is effective for motor and sensory recovery of the distal ulnar-innervated side of the hand.
