Summary
Origins
- Lateral border of the ischial tuberosity
Insertions
- Quadrate tubercle on the intertrochanteric crest of the 🦴 femur
Actions
- Laterally rotates the hip
- Adducts the 🦴 femur when needed
- Stabilizes the femoral head in the acetabulum
The quadratus femoris is a stout, rectangular muscle between the ischial tuberosity and intertrochanteric crest. It provides powerful lateral rotation of the femur and compresses the hip joint, acting as a strong counterpoint to the abductors.
