Autogenous vein graft was used to fill 18 digital nerve defects between 0.5 to 5.8 cm in length during flexor tendon surgery in zone 2. The vein was taken from the forearm and reversed to bridge the digital nerve. For nerves with defects over 2.0 cm, normal nerve slices were inserted inside vein conduits. Recovery of sensibility was evaluated by von Frey test, pin-prick detection, localization of stimulus, moving two-point discrimination and sweating on the finger pulp. Follow-up revealed excellent recovery in two digital nerves, good in nine, fair in five and poor in two. The results suggest that vein graft provides a simple and practical method to reconstruct a digital nerve defect during tendon repair in zone 2.
在2区屈肌腱手术中，采用自体静脉移植修复18例长度在0.5至5.8厘米之间的指神经缺损。静脉取自前臂并反转以桥接指神经。对于缺损超过2.0厘米的神经，将正常神经切片插入静脉导管内。通过von Frey试验、针刺检测、刺激定位、移动两点辨别和指腹出汗情况评估感觉恢复。随访结果显示，两条指神经恢复极佳，九条良好，五条尚可，两条较差。结果表明，静脉移植为2区肌腱修复时重建指神经缺损提供了一种简单实用的方法。
