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.%目的 介绍示中环指指固有神经背侧支移位,修复同指对侧指固有神经或邻指指固有神经撕脱离断伤的方法.方法 2003年8月至2008年12月,对56例72指指固有神经撕脱离断伤患者,取同指对侧或邻指相邻侧指固有神经背侧支移位,与受损指固有神经远断端缝合修复.结果 术后56例均获得6个月至1.5年的随访,平均1年2个月.修复侧指腹感觉均恢复,两点分辨觉为6～9 mm(平均7.3 mm),感觉为S4.指腹饱满.结论 示中环指指固有神经背侧支移位,修复同指对侧指固有神经或邻指指固有神经撕脱离断伤的方法,能恢复指腹良好感觉,方法简单,疗效确切.
