Description[edit | edit source]
The Tensor fascia latae(TFL) is a fusiform muscle enclosed between two layers of fascia lata with a length of 15cm approximately and overlying the gluteus minimus and some part of the gluteus medius. It's myotomes is fourth lumbar nerve root (L4)
Anatomy[edit | edit source]
Origin[edit | edit source]
TFL originates from anterior superior iliac spine(ASIS) and the anterior part of iliac crest
Insertion[edit | edit source]
TFL together with the gluteus maximus joins to form the Iliotibial tract, which attaches to lateral condyle of tibia
Nerve supply[edit | edit source]
The Tensor fasciae latae is innervated by superior gluteal nerve, originating from lumbar nerve 4, 5, and first sacral nerve(L4-S1) roots. It also innervates gluteus minimus and medius muscles before terminating with innervation of tensor fasciae latae muscle
Blood Supply[edit | edit source]
Blood is supplied to TFL via deep branch of superior gluteal artery
The superior gluteal vien a branch of the internal iliac viens serves as the venous drainage route.
Function[edit | edit source]
- TFL is prime mover in hip medial rotation and a weak hip abductor
- It serves as an accessory muscle in abduction and flexion of the hip
- Together with gluteus maximus and the illiotibal band, it stabilizes the hip joint by holding the head of the femur in the acetabulum
- The tensor of fasciae latae, together with the gluteus maximus contributes in stability of the knee during extension and also in partial flexion
- As part of the iliotibial tract it aids lateral rotation of the leg.
