Description
The quadratus femoris muscle is a small, quadrilateral-shaped muscle located in the posterior region of the hip. It originates at the ischial tuberosity (sit bone) of the pelvis and inserts into the lateral aspect of the femur (thigh bone) just below the greater trochanter. The quadratus femoris muscle is one of several muscles that make up the posterior compartment of the hip.
The main function of the quadratus femoris muscle is to laterally rotate (rotate outwardly) the femur at the hip joint. This movement is essential for activities such as walking and running, as it helps to stabilize the hip joint and prevent the thigh from swinging too far inwards. The quadratus femoris muscle also helps to extend the hip joint, bringing the thigh backwards.
