The obturator nerve is a major peripheral nerve of the lower limb. In this article, we shall look at its anatomical course, motor and sensory functions, and its clinical significance.
Overview
---------------
Nerve roots: L2-L4
Motor Innervates the medial (adductor) compartment of the thigh.
Sensory: Cutaneous branch innervates the skin of the medial thigh.
Anatomical Course
-------------------------------
The obturator nerve is formed by the anterior divisions of the second, third and fourth lumbar nerves.
It descends through the fibres of the psoas major muscle and emerges from its medial border, running posteriorly to the common iliac arteries and laterally along the pelvic wall to the obturator foramen. It then enters the thigh through the obturator canal and splits into anterior and posterior divisions.
The anterior division descends between the adductor longus and adductor brevis muscles towards the femoral artery, giving off branches to the adductor longus, adductor brevis, and gracilis muscles. In rare cases, it also gives off a branch to the pectineus muscle. It then pierces the fascia lata to become the cutaneous branch of the obturator nerve.
The posterior division descends through the obturator externus muscle before passing anteriorly to adductor Magnus and giving off branches to supply it.

CLINICAL CORRELATION Injury to this nerve will cause : 1) pain in the hip and knee joints respectively. 2) weak adduction of the legs. 3) loss of sensation in the medial aspect of thigh.
Ooooh thank you Dr. Bhanu. I needed a quick revision of the obturator nerve anatomy for a patient I suspect has obturator nerve entrapment. To the point and spot on. Thank you.
The posterior branch pierces obturator externus and descends between adductor brevis and adductor magnus. The anterior branch however passes between adductor longus and adductor brevis. The adductor brevis is innervated by both the divisions of the obturator nerve.
sir thank u so much .. it is said very clearly :) understood very well !!

The obturator nerve passes down beneath the psoas major and leaves the pelvis by passing through the obturator foramen.
First thank u very much for this clear explaining but excuse me doctor i have a Question:the skin of the medial side of the thigh innervated by Obturator Nerve and also by medial cutanous nerve of the thigh so why Obturator Nerve injury cause loss of sensation although medial cutanous nerve is present??

Wat about pectineus sir
Ant division also supplies Pectineus
confused about innervation to pectineus. is it femoral or obturator and accessory obturator nerve?
