【摘要】：目的探索兒童旋前圓肌和指淺屈肌的肌內(nèi)終末神經(jīng)密集區(qū)的分布范圍,為注射BTX-A治療腦癱患兒前臂肌痙攣提供解剖定位。方法使用改良的Sihler`s肌內(nèi)神經(jīng)染色法觀察兒童旋前圓肌和指淺屈肌的肌內(nèi)神經(jīng)分支分布模式。結(jié)果旋前圓肌的神經(jīng)入肌點(diǎn)有上、下兩個(gè),下部的神經(jīng)支較粗大、分布更廣,其肌內(nèi)神經(jīng)分支呈掃帚狀,相鄰各神經(jīng)分支末端可見(jiàn)明顯的"O"和"Y"型吻合,該肌的肌內(nèi)終末神經(jīng)密集區(qū)位于肌腹中部;指淺屈肌的神經(jīng)入肌點(diǎn)有上、中、下3個(gè),肌內(nèi)終末神經(jīng)密集區(qū)可分上、中、下3部,其中以中部最為密集,各終末神經(jīng)間可見(jiàn)"Y"、"O"吻合。結(jié)論鑒于兩肌的肌內(nèi)終末神經(jīng)密集區(qū)均位于肌腹中部,當(dāng)腦癱患兒旋前圓肌、指淺屈肌痙攣時(shí),使用BTX-A治療肌痙攣的最佳注射靶區(qū)應(yīng)選擇在肌腹中部。
[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.
