Abstract
Objective To introduce the surgical method of transferring dorsal branch of the proper digital nerve of index, middle or ring finger to the lacerated digital nerve on the opposite side of the same finger or the neighboring finger. Methods From August 2003 to December 2008, 72 lacerated proper digital nerves in 56 cases were repaired by transferring dorsal branch of the proper digital nerve from the opposite side of the same finger or from the neighboring side of the neighboring finger. The transferred nerve was coapted to the distal end of the lacerated nerve. Results All 56 cases were followed for 6 months to 1.5 years postoperatively, with an average of 14 months. Recovery of sensation of the reinnervated finger pulps was observed in all cases. Two-point discrimination was 6 to 9 mm, average being 7.3 mm. Sensory function was rated as S4. The pulps were full in contour. Conclusion Transferring dorsal branch of the proper digital nerve of index, middle or ring finger to the lacerated digital nerve on the opposite side of the same finger or the neighboring finger was a simple and effective method to restore sensory function of the pulp. Key words: Nerve transfer; Finger injuries; Dorsal branch of finger connatural nerve
