缝匠肌和股直肌肌内神经分布研究及其临床意义

Research and Clinical Significance on Sartorius and Rectus Femoris Intramuscular Nerve Distribution

目的:探讨和研究人体的缝匠肌和股直肌的肌内神经分布和临床意义,为临床外科提供肌形态学资料。方法:利用大体解剖法对20具尸体进行解剖,对缝匠肌和股直肌的形态学特点进行观察,以髂前上棘为标志,定位神经入肌点分别利用H.E染色法和Sihler肌内神经染色法对肌梭分布和神经分支分布进行观察。结果:缝匠肌是长肌束平行构建而成的带状肌,股直肌则是由短肌束构成的羽肌,两者的肌梭分布密度分别为38.04个/g和19.37个/g,缝匠肌的神经入肌点、股直肌外上部和内下部三者距离髂前上棘的直线距离分别为(9.75±1.30)cm、(10.23±0.97)cm和(14.48±1.12)cm。结论:缝匠肌是带状肌,而股直肌是羽肌,了解两者的神经分布对于临床外科手术有着重要的意义。

Objective：To explore and study the sartorius muscle rectus femoris and the distribution of intramuscular nerves and the clinical significance,providing morphological data for clinical surgery muscle.Methods：Using gross anatomical method in 20 cadavers were dissected,butt sartorius muscle rectus femoris and the morphological characteristics were observed,with the anterior superior iliac spine for the mark,localization of nerve entry point to the muscle respectively using E staining and Sihler H intramuscular nerve staining of muscle spindles and nerve branches were observed.Results：The sartorius muscle is long bundles in parallel is built up of the rectus femoris muscle,is a short bundles consisting of plume muscle,both muscle spindle distribution density were38.04/g and 19.37/g,sartorius muscle,nerve entering point of the rectus femoris and upper and lower three distance the anterior superior iliac spine straight distance were（9.75±1.30）cm,（10.23±0.97）cm and（14.48±1.12）cm.Conclusion：The sartorius muscle is the strap muscles,and the rectus femoris muscle is a feather,understanding of both nerve distribution for clinical surgical operation has important significance.
