Dr. Ebraheim’s educational animated video describes the anatomy of the obturator externus muscle. • The obturator externus is one of the six short external rotators of the hip. • Origin: it arises from the obturator foramen and the obturator membrane. • Insertion: it inserts into the trochanteric fossa of the femur. • Action: it laterally rotates and adducts the thigh. • Innervation: the obturator externus muscle is innervated by the posterior division of the obturator nerve. • Six short external rotators of the hip: • 1-Piriformis muscle. • 2-Superior gemellus muscle. • 3-Obturator internus muscle. • 4-Inferior gemellus muscle. • 5-Obturator externus muscle. • 6-Quadratus femoris muscle. • The short external rotators are used to protect the sciatic nerve. The sciatic nerve will be behind these muscles. • Follow me on twitter: • https://twitter.com/#!/DrEbraheim_UTMC
