Tensor fasciae latae originates on the outer aspect of the ilium and inserts on the iliotibial band or tract, a band of connective and contractile tissue extending down the outside of the thigh. Its principal functions are stabilization of the hip and knee joints, and assistance in abduction of the hip. Its trigger points typically refer into the hip and leg.

Tensor fasciae latae pain referral zone:

Translation: "Tensor fasciae latae" means "tightener of the wide bandage." It attaches to the underside of the upper ridge of your pelvis -- it's the muscle in that space on the side of your hip between your pelvis and your thighbone. It attaches below to a band of connective tissue that runs down the outside of your thigh to the outer top of your lower leg. It helps to lift the leg away from center, and to make the hip and knee joints more stable. Trigger points in this muscle can cause pain in the hip and down the outside of the thigh.
