ATTACHMENTS:

• 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.

ACTIONS:

• 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.

NOTES:

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.
