【摘要】：目的精确定位大腿肌内侧群痉挛肌外神经阻滞靶点的位置。方法设计经耻骨结节至股骨大转子外侧皮肤的连线为横向的H参考线,经耻骨结节至股骨内上髁水平的连线为纵向的L参考线。解剖暴露经甲醛固定的10具成人尸体的20侧闭孔神经及其肌支,涂抹硫酸钡于它们表面,烘干,X线摄片,PACS软件测量闭孔神经肌支肌外阻滞靶点在H线和L线上的百分位置。结果闭孔神经股薄肌支、长收肌支、短收肌支以及大收肌支在肌外的近侧运动点(P点)分别位于距耻骨结节外侧的大腿宽度(H线)的(21.48±1.80)%、(25.85±1.23)%、(28.07±1.65)%和(29.18±2.07)%处,位于距耻骨结节远侧的大腿长度(L线)的(8.83±1.01)%、(8.83±1.01)%、(7.57±0.63)%和(7.57±0.63)%处;远侧运动点(D点)分别位于距耻骨结节外侧大腿宽度(H线)的(16.9±1.33)%、(27.70±2.15)%、(31.18±2.18)%和(35.78±2.79)%处,位于距耻骨结节远侧大腿长度(L线)的(35.57±2.77)%、(26.9±1.96)%、(24.26±1.91)%和(28.04±2.17)%处。结论这些靶点的准确定位可提高大腿肌内侧群痉挛肌外神经靶点阻滞的安全性和有效性。
[Abstract]:Objective to locate precisely the position of the target of extramuscular nerve block in the medial group of thigh muscle. Methods the line from the pubic tubercle to the lateral skin of the greater trochanter of the femur was designed as the transverse H reference line, and the line from the pubic tubercle to the level of the medial epicondyle of the femur was designed as the longitudinal L reference line. Twenty obturator nerves and their muscular branches of 10 adult cadavers fixed by formaldehyde were dissected and barium sulfate was applied on their surfaces. The PACS software was used to measure the percentage of the external blocking targets of muscle branches of obturator nerve on H and L lines. Results the proximal motor points (P point) of the obturator nerve thin muscle branch, long adductor branch, short adductor branch and adductor Magnus branch were located at (21.48 卤1.80), (25.85 卤1.23), (28.07 卤1.65)% and (29.18 卤2.07)%, respectively, of the thigh width (H line) outside the pubic tubercle, and (28.07 卤1.65)% and (29.18 卤2.07)%, respectively. 浣嶄簬璺濊，
