To identify the precise location of the motor points of hip adductors in relation to bony landmarks.
Nineteen limbs from ten adult cadavers were anatomically dissected. The motor point of each adductor muscle was determined by measuring its distance from the pubic tubercle with reference to a line joining the pubic tubercle and the medial epicondyle of the femur, and this distance was expressed as a percentage. For describing the mediolateral relationship between the motor point of each adductor and bony landmarks, its distance from the pubic tubercle was measured with reference to a line joining the pubic tubercle and the greater trochanter of the femur, and the result was expressed as a percentage.
The percent distances along the longitudinal reference line distal to the pubic tubercle were as follows: adductor longus, 26.0% +/- 4.8%; adductor brevis, 21.0% +/- 4.8%; gracilis, 32.1% +/- 2.1%; and adductor magnus, 30.4% +/- 4.1%. Further, the percent distances along the horizontal reference line lateral to the pubic tubercle were as follows: adductor longus, 24.9% +/- 7.8%; adductor brevis, 24.9% +/- 7.4%; and adductor magnus, 33.6% +/- 5.9%.
Identification of these motor points facilitates the efficacy and efficiency of a neural blockade and decreases undesirable complications.
确定髋内收肌运动点相对于骨性标志的精确位置。
对来自10具成年尸体的19条下肢进行解剖。通过测量每条内收肌运动点与耻骨结节的距离（以连接耻骨结节和股骨内侧髁的线为参照）来确定其运动点，并将该距离表示为百分比。为描述每条内收肌运动点与骨性标志之间的内外侧关系，测量其与耻骨结节的距离（以连接耻骨结节和股骨大转子的线为参照），结果表示为百分比。
沿耻骨结节远端纵向参照线的百分比距离如下：长收肌，26.0%±4.8%；短收肌，21.0%±4.8%；股薄肌，32.1%±2.1%；大收肌，30.4%±4.1%。此外，沿耻骨结节外侧水平参照线的百分比距离如下：长收肌，24.9%±7.8%；短收肌，24.9%±7.4%；大收肌，33.6%±5.9%。
识别这些运动点有助于提高神经阻滞的有效性和效率，并减少不良并发症。
