Quadratus femoris muscle
== Quadratus femoris muscle ==
The quadratus femoris muscle is a flat, quadrilateral skeletal muscle located in the gluteal region of the lower limb. It is one of the six external rotators of the hip and plays a crucial role in the lateral rotation and stabilization of the hip joint.
Anatomy[edit | edit source]
The quadratus femoris muscle originates from the lateral border of the ischial tuberosity of the pelvis. It inserts into the quadrate tubercle on the intertrochanteric crest of the femur and the area immediately below it.
Innervation[edit | edit source]
The muscle is innervated by the nerve to quadratus femoris, which is a branch of the sacral plexus. This nerve also innervates the inferior gemellus muscle.
Blood Supply[edit | edit source]
The blood supply to the quadratus femoris muscle is primarily provided by the medial circumflex femoral artery and the inferior gluteal artery.
Function[edit | edit source]
The primary function of the quadratus femoris muscle is to laterally rotate the thigh at the hip joint. It also helps to stabilize the head of the femur in the acetabulum of the pelvis.
Clinical Significance[edit | edit source]
Injuries or conditions affecting the quadratus femoris muscle can lead to pain and dysfunction in the hip region. One such condition is quadratus femoris muscle tear, which can result from trauma or overuse.
