Tensor of the Iliotibial Tract (Fascia Lata)
Region: Hip & Thigh Muscles · All hip & thigh muscles
Tensor of the Iliotibial Tract (Fascia Lata) at a glance
| Origin | Iliac crest via the fascia lata (deep fascia of the thigh) |
|---|---|
| Insertion | Iliotibial tract blending to the lateral tibial condyle |
| Actions | Braces the extended knee from the side |
| Nerve supply | Superior gluteal nerve (via tensor fasciae latae, L4–L5) |
◆ Good to know
Strictly the thigh's deep fascia rather than a muscle belly — included because its tensioning muscle, tensor fasciae latae, is a common source of lateral knee symptoms.
