Which structure attaches to the iliac tubercle as part of the iliotibial region?

• A. Tensor fascia lata
• B. Gluteal aponeurosis fascia
• C. Iliotibial tract
• D. Sartorius

Answer: (C)

The iliotibial tract is the proximal anchor in the iliotibial region. This thick band of fascia runs along the lateral thigh, arising from structures around the iliac crest and banding with the tensor fasciae latae and gluteus maximus, then extending down to insert on the lateral tibial condyle (Gerdy’s tubercle). The iliac tubercle, a small bump on the iliac crest, marks the proximal attachment point of this tract. So, in this region, the structure that attaches there is the iliotibial tract. The other structures relate to different regions or functions: sartorius starts at the ASIS and goes to the medial tibia, the gluteal aponeurosis fascia covers the gluteal area, and the tensor fasciae latae contributes to the IT band but the attachment at the tubercle is characteristic of the iliotibial tract itself.
