Abstract
OBJECTIVE: To identify the precise location of the motor points of hip adductors in relation to bony landmarks. DESIGN: 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. RESULTS: 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%. CONCLUSIONS: Identification of these motor points facilitates the efficacy and efficiency of a neural blockade and decreases undesirable complications.
