Description[edit | edit source]
Quadratus femoris is a short, flat and rectangular muscle. It is situated inferior to the obturator internus and gemelli.[1]It is striated in appearance and is bordered anteriorly by the obturator externus and posteriorly by the sciatic nerve and fat[2].
Origin[edit | edit source]
Infeorlateral margain of the ischium along the anterior part of the ischial tuberosity.[1][2]
Insertion[edit | edit source]
Quadrate tubercle of the intertrochanteric crest of the femur and area inferior to it.[1][2]
Nerve[edit | edit source]
Nerve to quadratus femoris (L4, L5 and S1).[1][2]
Artery[edit | edit source]
Inferior gluteal artery.[1]
Function[edit | edit source]
- Externally rotates the hip[2]
- Assists in adduction of the hip[2]
- Stabilises the femur head in the acetabulum[1]
Clinical relevance[edit | edit source]
- Groin pain[3]
- Groin Strain[4]
- Muscle tear[5]
- Tendinitis[3]
- Ischiofemoral impingement[5][6]
Assessment[edit | edit source]
- Palpation
- Muscle length testing
- Muscle strength testing
- Functional tests.
Treatment[edit | edit source]
- Muscle stretching
- Strengthening
- Soft tissue/trigger point release
