本文用21例成人坐骨神经,其中20例用醋酸滴浸,在肉眼和手术显微镜下解剖分离:1例做断面厚片和组织学切片照像。作者观察了坐骨神经干的位置、形态、大小和束数,绘制了坐骨神经干各断面的局部定位图,记录了名肌支和主要皮支发出的部位、粗度、束数和可分离长度。文中报道腓总神经从腓骨颈向上外到腘窝后面旋转了近180°。因神经干贴近骨面和大幅度地旋转,故在此处神经易受损伤。
In this study, 21 adult sciatic nerves were used, of which 20 were implanted with acetic acid and dissected under the naked eye and under a surgical microscope: one case was sectioned and histologically sectioned. The author observed the position, shape, size and number of the sciatic nerve trunk. The local map of each section of the sciatic nerve trunk was drawn, and the location, roughness, number of beam and detachable length of the muscle branch and the major dermal branch were recorded. The article reported that the common peroneal nerve from the fibula neck up to the popliteal behind rotated nearly 180 °. Because the nerve stem close to the bone surface and a substantial rotation, so nerves here vulnerable.
