adductor magnus muscle

Hip and thigh muscle. Origin: inferior ramus of pubis, ramus of ischium, ischial tuberosity. Insertion: linea aspera and adductor tubercle of femur. Nerve: obturator and sciatic (L2-L4). Action: adducts, flexes, and rotates thigh medially.

1 = Pectineus muscle, 2 = PMB belongs to femoral nerve, 3 = Gracilis muscle, 4 = GMB, 5 = Adductor longus muscle, 6 = ALMB, 7 = Adductor brevis muscle, 8 = ABMB, 9 = Adductor magnus muscle, 10 = AMMB.
The body surface landmarks A = Greater trochanter of femur; B = lateral femoral epicondyle; C = pubic tubercle; P1~P5 are the projection points of NEPs of pectineus, gracilis, adductor longus, adductor brevis and adductor magnus muscle, respectively.
The posterior obturator nerve branch travels in the fascia between the adductor brevis and adductor magnus muscles (Figure 1(a)).
Subsequently, local anesthetic is injected in the fascia between the adductor brevis and adductor magnus muscles to block the posterior branch of the obturator nerve [30, 38].
Then it passes anterior to the adductor magnus muscle, dividing into branches to adductor magnus and occasionally the adductor brevis.
The fascia from the obturator externus and adductor magnus muscles was removed without damaging the branches of the obturator nerve.
The NEP of the adductor magnus muscle was selected for localization measurements and identified as follows: L'/L x 100 % = 22.75 % (Fig.
