摘要
对15只家兔以不同速度与幅度缓慢延长小腿,进行电生理与组织形态学研究,观察胫神经功能变化。结果表明:以每天1mm速度延长肢体,不会引起神经形态改变与功能损害,运动神经传导速度及肌肉动作电位均正常。以每天2mm速度延长,肢体延长40％以内也是安全的。认为周围神经对缓慢牵引延长具有很大适应性。
The changes of nerve function were observed from the study of electrophysiology and histomorphology in 15 rabbits undergoing gradual lengthening of the legs from different rates and magnitudes. The results showed that if the leg was increased at a rate of 1 mm per day would not result in any changes of nerve morphology or functional damage. The conduction rate of the motor nerve and the potential of the muscular action were all normal; if at a rate of 2mm per day, the leg length was increased within 40％, it was still quite safe. It was believed that the peripheral nerve was markedly tolerable to gradual lengthening from traction.
