The tensor fasciae latae originates on which structure?

• A. iliac crest
• B. greater trochanter
• C. ischial tuberosity
• D. pubic symphysis

Answer: (A)

The main idea here is knowing where the tensor fasciae latae begins. The tensor fasciae latae originates from the anterior part of the iliac crest (near the ASIS). From there the muscle fibers run laterally and form the iliotibial band, which inserts distally on the lateral aspect of the knee. Therefore, the iliac crest is the correct structure.

The greater trochanter is where the gluteus medius and minimus attach, not the tensor fasciae latae. The ischial tuberosity is a common origin for many hamstring muscles. The pubic symphysis is a joint location and not a muscle origin for the TFL.
