Deep hip rotator muscles


Description

This group of six muscles is closely correlated with the body wall of the pelvic region. Five of the six muscles are positioned deep to the gluteal musculature on the posterior aspect of the hip joint where they span from the greater sciatic notch above to the ischial tuberosity below. Nerves and vessels leaving the pelvis to enter the posterior aspect of the lower limb pass between some of the muscles in this group. The deep hip rotator muscles share both attachments and actions in common. All the muscles insert on the greater trochanter of the femur and they all laterally rotate the hip joint. They serve as important stabilizers of the hip joint during locomotion.

Muscles Included

Obturator externus, Obturator internus, Superior gemellus, Inferior gemellus, Piriformis, and the Quadratus femoris
