摘　　要：目的通过研究幼儿长收肌和短收肌肌内神经支配区的分布定位,并探讨其可能意义。方法血管灌注和改良的Sihler’s肌内神经染色法观察幼儿长收肌和短收肌肌内神经和血管分布。结果长收肌腹外侧中间区域肌内神经末梢分布较密集,从内侧缘中上1/3交界处向外下走行至外侧缘中部区域肌内神经末梢分支呈带状分布,仅有3~5条细小的血管分支从此密集带中间部分穿过;短收肌内侧缘中间向外侧缘中间区域肌内神经末梢分支密集呈带状分布,此密集区域内未见血管及分支分布。结论幼儿长收肌内侧缘中上1/3交界处向外下走行至外侧缘中部区域和短收肌内侧缘中间向外侧缘中间区域可能是BTX-A注射治疗脑瘫患儿肢体痉挛的最佳注射靶区。Objective To study the intramuscular nerve innervation zones of adductor longus and adductor brevis and explore its possible significance. Methods Arterial perfusion was performed to identify vessel distribution.And modified Sihler＇s stain was performed to identify intramuscular nerve distribution of adductor longus and adductor brevis in cadavers from children. Results In adductor longus,the intramuscular nerve endings are densely distributied in the middle area of ventral lateral region of the muscle. The intramuscular nerve branches appear in zonal distribution from middle edge upper 1 /3 to the central region of lateral margin. There are only 3 to 5 small vascular branches traverse through this nerve fiber dense zone. In adductor brevis,the intramuscular nerve endings appear as an intensive zonal distribution from medial margin to lateral edge in the middle region of the muscle. There are no vascular branches in this area. Conclusion In children,both the area between the middle and upper 1 /3 on the medial edge and the midpoint on the lateral edge in adductor longus and the area in the middle region of the muscle in adductor brevis might be the potent target areas for BTX- A injection to treat lower limb spasticity caused by cerebral palsy.
