The medial circumflex femoral artery traverses between the adductor magnus and the adductor longus muscles
and enters the deep surface of the gracilis muscle approximately 6-10 cm inferior to the pubic tubercle [Figure 3].
Throughout its course, the nerve usually supplies multiple branches to the adductor magnus and adductor brevis muscles and occasionally innervates the obturator externus and adductor longus muscles as well .
ON, obturator nerve; AL, adductor longus muscle; AB, adductor brevis muscle; AM, adductor magnus muscle; PE, pectineus muscle; OE, obturator externus muscle; SPR, superior pubic ramus; GR, gracilis muscle.
The femoral triangle is bounded superiorly by the inguinal ligament, medially by the adductor longus, laterally by the sartorius, and posteriorly by the iliopsoas, pectineus and adductor longus muscles
. From lateral to medial, the femoral triangle contains the femoral nerve, artery, and vein.
The sartorius muscle was detached from its proximal attachment, and the femoral triangle was dissected free to reveal the femoral vessels and their branches, the pectineus, and the adductor longus muscles
. The adductor longus muscle
was divided transversely 1-2 cm below its origin.
