【摘要】：目的探索儿童旋前圆肌和指浅屈肌的肌内终末神经密集区的分布范围,为注射BTX-A治疗脑瘫患儿前臂肌痉挛提供解剖定位。方法使用改良的Sihler`s肌内神经染色法观察儿童旋前圆肌和指浅屈肌的肌内神经分支分布模式。结果旋前圆肌的神经入肌点有上、下两个,下部的神经支较粗大、分布更广,其肌内神经分支呈扫帚状,相邻各神经分支末端可见明显的"O"和"Y"型吻合,该肌的肌内终末神经密集区位于肌腹中部;指浅屈肌的神经入肌点有上、中、下3个,肌内终末神经密集区可分上、中、下3部,其中以中部最为密集,各终末神经间可见"Y"、"O"吻合。结论鉴于两肌的肌内终末神经密集区均位于肌腹中部,当脑瘫患儿旋前圆肌、指浅屈肌痉挛时,使用BTX-A治疗肌痉挛的最佳注射靶区应选择在肌腹中部。
[Abstract]:Objective to explore the distribution of the endofrequency nerve dense area in children's flexor digitorum and circumflex muscle so as to provide anatomic location for the treatment of spasm of forearm muscle by BTX-A injection in children with cerebral palsy. Methods Sihler's intramuscular nerve staining was used to observe the distribution pattern of intramuscular nerve branches in children's anterior circle and flexor digitorum. Results the nerve entry points of the circumflex teres muscle were upper and lower, and the nerve branches in the lower part were thicker and wider. The intramuscular nerve branches were broomlike, and there were obvious "O" and "Y" anastomoses at the ends of the adjacent nerve branches. The central part of the intramuscular terminal nerve of the muscle is located in the middle of the muscle. The nerve entry points of the flexor digitorum superficial muscle are upper, middle and lower 3, and the dense area of the intramuscular terminal nerve can be divided into three parts, the middle of which is the most dense, and the "Y" and "O" anastomosis can be seen among the terminal nerves. Conclusion in view of the fact that the intramuscular terminal nerve dense areas of the two muscles are located in the central part of the muscle, the best injection target for the treatment of muscle spasm with BTX-A should be in the middle of the muscle when the spasm of the anterior circumflex muscle and flexor digitalis muscle is in children with cerebral palsy.
