Here it enters the thigh, through the obturator canal, and divides into an anterior and a posterior branch, which are separated at first by some of the fibers of the obturator externus, and lower down by the adductor brevis. [2] An accessory obturator nerve may be present in approximately 8% to 29% of the general population. [3]
The anterior branch of the obturator nerve is a branch of the obturator nerve found in the pelvis and leg. [1]It leaves the pelvis in front of the obturator externus and descends anterior to the adductor brevis, and posterior to the pectineus and adductor longus; at the lower border of the latter muscle it communicates with the anterior cutaneous and saphenous branches of the femoral nerve ...
When present it emerges from beneath the distal/inferior border of the adductor longus muscle and descends along the posterior margin of the sartorius muscle to [1] the medial side of [citation needed] the knee where it pierces the deep fascia and communicates with the saphenous nerve. When present, it provides sensory innervation to the skin ...

the cutaneous branch of anterior division of the obturator nerve. [ 1 ] At the lower border of the adductor brevis muscle , the cutaneous branch of anterior division of the obturator nerve communicates with the anterior (medial), cutaneous and saphenous branches of the femoral nerve, forming a kind of plexus.
The posterior branch of the obturator nerve pierces the anterior part of the obturator externus, and supplies this muscle; it then passes behind the adductor brevis on the front of the adductor magnus, where it divides into numerous muscular branches which are distributed to the adductor magnus and the adductor brevis.
One of these supplies the pectineus, penetrating its deep surface, another is distributed to the hip-joint; while a third communicates with the anterior branch of the obturator nerve. Occasionally the accessory obturator nerve is very small and is lost in the capsule of the hip-joint. When it is absent, the hip-joint receives two branches from ...
