摘要
目的研究臀部坐骨神经解剖特点与临床关系。方法在５８具成人尸体标本上观测了臀部坐骨神经的毗邻、长度周径及自然分束等。结果臀部坐骨神经骨盆段后方紧贴骶髂关节。臀肌段后方仅为臀大肌所覆盖，该段前方为髋关节。５８具臀部坐骨神经测量结果：盆腔段长度为９．３３±０．７４ｃｍ；直径为７．９±１．９７ｍｍ．梨状肌段长度为３．６７±０．６２ｃｍ；直径为１５．１０±２．２９ｍｍ。臀大肌段长度为１７．０３±１．３７ｃｍ；直径为１１．０２±２．１６ｍｍ；臀部胫神经自然分束数为２０±２．８７；腓总神经为１１±１．７０。臀部坐骨神经干轴索分布清楚、神经滋养血管标志恒定，重要分支少，神经游离度大，局部血运丰富等。
bjectives To investigate the anatomical characteristics of sciatic nerve in cluneal region and its clinical significance.Methods The syntopy,length,diameter and native boundles of sciatic nerve in cluneal region were observed on 58 adult cadaver specimens.Results Posterior of sciatic nerve in the pelvis is close toscroiliac joint.The sciatic nerve in cluneal region is just overjected by the musculus posterior and hip joint anterior.Sciatic nerves are measured in 58 Corpses the result as follow:the average length in pelvis is 9.33±0.74cm and theauerag diameter is 7.9±1.97mm.The average length and diameter in musculus pirformis is 3.67±0.62cm and 15.10±2.29mm.The average length and diameter in the musculus is 17.03±1.37cm and 11.02±2.16mm.The spontaneous bunch of the nerve tibiatis in cluneal is 20±2.87.The nerve peroneuscommunis is 11±1.70.The sciatic nerve in cluneal region owns many movableranges,clear neurits distribution,rich in local bloodcirculation,constant nutritious vessel marker and fewramifications.Conclusions The sciatic nerve injury cluneal region should be repaired positively.
