摘要: |
目的:了解截瘫后下肢神经的病理改变。 方法:(1) 将实验犬的脊髓从T11-12平面完全横断,分别于第3,6周取出下肢主要神经干,切片、染色后,光镜下观察神经纤维形态学改变;(2) 在给陈旧性截瘫患者行肋间神经转位、腓肠神经移植桥接马尾手术的同时,切取腓肠神经行病理切片检查。结果: 实验犬的下肢神经未见明显变性,截瘫患者的腓肠神经组织形态基本正常。结论: T11以上脊髓损伤截瘫后,下肢神经无明显变性。 |

Abstract: |
Objective: To study the nerve degeneration of lower extremity after paraplegia. Methods: (1) The spine cord of experimental dogs were severed between T11-12. The section of main nerve trunks of lower extremities were studied under microscope after 3-6 weeks; (2) the sural nerve of later paraplegic patients were analyzed. Results: No obvious degeneration was found in the nerve of lower extremities of experimental dogs and later paraplegic patients. Conclusion: No obvious degeneration is found in lower extremity nerve if the injury plane is higher than T11. |
