The tensor fasciae latae mainly flexes, abducts, and medially rotates the hip. Its origin on the anterior iliac crest and insertion into the iliotibial tract place its pull in front of the hip joint axis, so contraction brings the thigh forward (flexion), moves it away from the midline (abduction), and, when the hip is flexed, rotates the thigh inward (medial rotation). This combination best captures its actions at the hip, and explains why it does not primarily extend the hip or laterally rotate.
