坐骨神经的损伤对下肢功能影响较大,以下对坐骨神经损伤的描述,错误的是

A.如损伤部位在坐骨大孔处或坐骨结节以上,则股后肌群,小腿前、外、后肌群及足部肌肉全部瘫痪

B.如在股部中下段损伤,只表现为膝以下肌肉瘫痪,膝以上肌肉无影响

C.如为其分支损伤,则腓总神经损伤引起的瘫痪重,胫神经损伤引起的瘫痪轻

D.膝以下除小腿内侧及内踝处隐神经供给区外,感觉均消失

E.往往有严重的营养障碍,足底部形成溃疡

答案

参考答案:C

解析:[解题思路] 胫神经损伤瘫痪者,行走时足跟离地困难,不能走快,足内肌瘫痪弓状足和爪状趾畸形,其感觉丧失区较大,足底部常有溃疡,足部易受外伤、冻伤、烫伤,常因溃疡不能走路。而腓总神经瘫者足呈下垂状,走路时仅需抬高患肢即可,感觉障碍为足背部较小范围,故胫神经损伤引起的瘫痪重。
