The nerve to quadratus femoris is a nerve that provides innervation to the quadratus femoris and gemellus inferior muscles.

Course

The nerve to quadratus femoris is a sacral plexus nerve. It arises from the ventral divisions of the fourth and fifth lumbar and first sacral nerves: it leaves the pelvis through the greater sciatic foramen, below the piriformis muscle, and runs down in front of the sciatic nerve, the superior and inferior gemellus muscles, and the tendon of the obturator internus, and enters the anterior surfaces of the muscles; it gives an articular branch to the hip-joint.
