Adductor longus is the most anterior and superficial of the adductor muscles of the medial compartment of the thigh. It forms the medial boundary of the femoral triangle.
The actions of adductor longus are primarily those of adduction and flexion of the thigh. However, it may also laterally rotate the flexed hip and fix the thigh during movements at the knee.
The origin of adductor longus is the body of the pubis inferior to the pubic tubercle via a tough, rounded tendon that may be ossified. It inserts into the lower two thirds of the linea aspera on the posterior aspect of the femur.
The innervation to adductor longus is the obturator nerve (L2,3,4).
