The tensor fascia lata is a muscle of the gluteal region in the lower limb. It is a small superficial muscle which lies towards the anterior edge of the iliac crest. It functions to tighten the fascia lata, and so abducts and medially rotates the lower limb. Attachments: Originates from the anterior iliac crest, attaching to the anterior superior iliac spine (ASIS). It inserts into the iliotibial tract, which itself attaches to the lateral condyle of the tibia. Actions: Abduction and medial rotation of the lower limb. Innervation: Superior gluteal nerve. Blood Supply: Superior gluteal artery. By TeachMeSeries Ltd (2025) Fig 1The tensor fascia lata and iliotibial tract.
