Right lateral view of the tensor fasciae latae (TFL). The iliotibial band is shown. The gluteus maximus has been drawn in.

  • The tensor fasciae latae (TFL) attaches from the ASIS and anterior iliac crest to the iliotibial band (ITB), one-third of the way down the thigh.



  • The TFL flexes, abducts, and medially rotates the thigh at the hip joint.
  • It anteriorly tilts, depresses, and ipsilaterally rotates the same-side pelvis at the hip joint.



  1. The tensor fasciae latae is one of two muscles that attach into the iliotibial band (ITB). The other muscle is the gluteus maximus.
  2. A chronically tight tensor fasciae latae can be involved in ITB friction syndrome.
