摘　　要：本实验用带蒂或游离骨骼肌作为神经移植体分别做10mm,12mm和15mm长大白鼠坐骨神经缺损的桥接并分别在12、14和16周取材进行组织学切片和透射电镜以及肌电图观察。以上3种长度神经缺损均用骨骼肌桥接。可观察到再生神经纤维沿着肌纤维间隙成功地通过两个吻合口到达神经远端,时间越长神经纤维在肌桥中越趋向成熟和增粗。运用大体观察和组织学染色和透射电镜以及肌电图比较带蒂或游离骨骼肌作为神经桥接体2种方法,认为后者更具有实用性。We used sheletal muscle of various lengths to repair defect of peripheral nerves in our animal experiments. Both pedicled skeletal muscular graft and free skeletal muscular graft, as nerve grafting conduits, were compared and observed under electron microscope. The finding showed that free skeletal muscular graft used as nerve grafting conduits were more helpful to the regenenation of nerve fibers, compased with pedicled skeletal musular graft, especially to nerve defect in places with abound tendon such as wrist and ankle.
