The medial compartment of the thigh is frequently called the adductor compartment because the major action of this group of muscles is adduction, except for the hamstring portion of the adductor magnus which performs as a hamstring and is supplied by a different nerve than the obturator, which supplies the muscles of the medial compartment. All the medial thigh muscles are innervated by the obturator nerve, which arises from the lumbar plexus. Arterial supply is via the obturator artery.
The muscles in the medial compartment of the thigh are collectively known as the hip adductors. There are five muscles in this group; gracilis, obturator externus, adductor brevis, adductor longus and adductor magnus.
The femoral triangle is formed by the sartorius muscle laterally, the adductor muscles medially, and the inguinal ligament superiorly. Three important structures passing under the inguinal ligament and into this triangle: the femoral artery and vein, and the femoral nerve.
The waveblade can assist in lymphatic drainage and circulation via the great saphenous vein in the adductor region of the hip.
The great saphenous vein is a large superficial vein of the lower limb. It drains into the femoral vein, which is the medial most structure in the femoral triangle. The lateral border of the femoral triangle is formed by the medial border of sartorius, the medial border of the femoral triangle is formed by the medial border of adductor longus and the inguinal ligament forms the base of the triangle. The point at which it drains into the femoral vein is known as the saphenofemoral junction.
