The aims of this study were to clarify the intramuscular branching patterns and arborizing area of hip adductor muscles with reference to surface landmarks on the thigh and to thus suggest effective and safe injection points for botulinum neurotoxin (BoNT).
Ten gracilis and 10 adductor longus specimens were subjected to Sihler staining to reveal intramuscular nerve arborization patterns, and findings were matched with and referred to surface landmarks. Using these results, we determined the optimal location for BoNT injection in hip adductors in relation to the long axis of the femur.
The corrected, most dense areas of innervation in adductor longus and gracilis were typically 30-50% and 40-50% from the anterior superior iliac spine (ASIS) along the vertical line of the femur, respectively.
The most effective and safest point for BoNT injection into adductor muscles appears to be between 35% and 50% from ASIS, where neuromuscular junctions are most densely distributed.
本研究旨在通过大腿表面标志明确内收肌的肌内分支模式和分支区域，从而为肉毒毒素（BoNT）的注射提供有效和安全的注射点。
对 10 例股薄肌和 10 例内收长肌标本进行 Sihler 染色，以显示肌内神经分支模式，并将结果与表面标志相匹配。利用这些结果，我们确定了与股骨长轴相关的内收肌中 BoNT 注射的最佳位置。
在股直肌和股薄肌中，经过修正的、最密集的神经支配区域通常分别距髂前上棘（ASIS）前上 30-50%和 40-50%，沿着股骨的垂直线。
对于内收肌 BoNT 注射，最有效和最安全的点似乎在 ASIS 前上 35%-50%的位置，此处神经肌肉接头分布最密集。
