摘要
在30侧成人标本上,对坐骨神经盆腔出口进行了应用解剖学研究,观测了坐骨神经盆腔出口的位置、构成、分段和各段的毗邻关系。坐骨大孔处伸展性最小,是容易发生绞勒之处。坐骨神经干上部滋养血管多从内侧进入,在行手术松解时,神经外侧和背侧为安全入路。据测量数据,神经背面松解的深度不应超过3.5cm。
The outlet of sciatic nerve from pelvic cavity was studied on 30 adult cadavers.The position and component parts of the outlet and its relationship with surrounding-tissue were observed and measured.The sciatic nerve is easy to be incarcerated at thegreatersciatic foramen where the stretch is the smallest.If neurolysis of the nerve isperformed,the lateral and dorsal sides are much safe to enter because the nutrientvessels go into the nerve mostly from the medial side.Based on our studing data,thedepth of the lysis at dorsal side of the nerve should not be more than 3.5cm in thecavity.If the sacrotuberous ligament is partly resected,the infrapiriformis foramencan be enlarged.
