【摘要】： 目的:坐骨神经的解剖学特点是临床坐骨神经阻滞的基础。本研究的目的:(一)应用超声技术,观察坐骨神经的解剖特点及其在臀区和大腿后侧的体表投影与体表标志之间的关系;(二)观察坐骨神经的各解剖参数与个体差异之间的相关性。 方法:本研究对25例志愿者的坐骨神经行超声描述。应用4～7MHZ的扇性超声探头,在臀区找到梨状肌和穿出梨状肌的坐骨神经,然后沿坐骨神经走行向下移动超声探头到臀下沟水平;用10～15MHZ的高频矩阵超声探头沿坐骨神经走行在大腿后逐渐下移到乆窝底。记录坐骨神经在臀区的体表投影与脊柱中线的距离和在大腿后的体表投影与大腿后中线的距离;测量超声横切面图中坐骨神经的宽和高及最上缘距皮肤的深度。并对各参数进行比较和分析。 结果:坐骨神经的解剖结构左右对称;在臀区的平均宽度为1.34±0.24cm～2.14±0.37cm,在下肢的平均宽度为0.84±0.16cm～1.28±0.19cm;坐骨神经在臀区的平均深度为4.60±0.55cm～6.08±0.68cm,在下肢的平均深度为2.29±0.82cm～3.99±0.41cm;坐骨神经在臀区的走行基本与脊柱中线平行,相距9.56±0.61cm～10.05±0.60cm;坐骨神经在下肢的体表投影基本位于大腿后中线。坐骨神经在臀区和下肢的体表投影与国人的性别、年龄、体重和身高之间无明显相关性。 结论:坐骨神经的体表投影在臀区与脊柱中线平行,相距约10cm;在下肢与“大腿后中线”基本一致。坐骨神经的体表投影与个体差异无明显的相关性。
[Abstract]:Objective: the anatomical characteristics of sciatic nerve are the basis of clinical sciatic nerve block. The purpose of this study is: (1) to apply ultrasonic technology, To observe the anatomical characteristics of sciatic nerve and the relationship between the surface projection and body surface markers in the gluteal area and the posterior thigh. (2) to observe the correlation between the anatomical parameters of sciatic nerve and individual differences. Methods: the sciatic nerve of 25 volunteers was described by ultrasound. The sciatic nerve of piriformis and piriformis was found in the gluteal area with 4~7MHZ 's fan ultrasonic probe, and then the ultrasonic probe was moved down the sciatic nerve to the level of the inferior gluteal sulcus. The high frequency matrix ultrasound probe of 10~15MHZ was used to walk along the sciatic nerve and gradually move down to the bottom of the nests after the thigh. The distance between the surface projection of sciatic nerve in the gluteal area and the midline of the spine and the distance between the surface projection of the sciatic nerve in the posterior thigh and the posterior midline of the thigh were recorded, and the width and height of the sciatic nerve and the depth from the upper edge to the skin were measured. The parameters are compared and analyzed. Results: the anatomical structure of sciatic nerve was symmetrical. The average width in the gluteal area was 1.34 卤0.24cm~2.14 卤0.37 cm, in the lower extremity was 0.84 卤0.19 cm, the average depth of the sciatic nerve in the gluteal area was 4.60 卤0.68 cm, and the average depth in the lower extremity was 2.29 卤0.82cm~3.99 卤0.41 cm. The distance was 9.56 卤0.61cm~10.05 卤0.60cm.The sciatic nerve projection on the lower limb was basically located in the midline of the posterior thigh. There was no significant correlation between the projection of sciatic nerve in the gluteal area and lower extremity and sex, age, weight and height of Chinese. Conclusion: the surface projection of sciatic nerve is parallel to the midline of spine in the gluteal area, and is consistent with the posterior midline of thigh in lower extremity. There was no significant correlation between the body surface projection of sciatic nerve and individual difference.
