The anterior interosseous nerve was transferred to the recurrent branch of the median nerve and the deep branch of the ulnar nerve respectively to restore the function of the intrinsic hand muscles. Twelve Rhesus monkeys were used with 24 nerves for transference and 24 for direct suturing. Gross, histological, and ultrastructural observations, electrophysiological evaluation and computer-imaging analysis system were employed to assess the nerve regeneration process in 1,3,6, and 12 months after operation. The results showed that the rate of maturity and the number of regenerating nerves in the distal segment approached the normal level and the passing rate of the myelinated axons reached to 156.16 +/- 14.45% 12 months after operation. According to the histological findings and the recovery of the intrinsic hand muscle function, reinnervation in the transferred nerves occurred 1 to 3 months earlier than that in the directly sutured ones.
将骨间前神经分别转移至正中神经返支和尺神经深支，以恢复手部固有肌功能。选用12只恒河猴，24条神经用于转移，24条用于直接缝合。采用大体、组织学和超微结构观察、电生理评估及计算机成像分析系统，对术后1、3、6和12个月的神经再生过程进行评估。结果显示，术后12个月，远段神经的成熟率和再生神经数量接近正常水平，有髓轴突通过率达到156.16±14.45%。根据组织学结果和手部固有肌功能恢复情况，转移神经的再支配比直接缝合神经提前1至3个月出现。
