Which term denotes the iliac tuberosity?

• A. Iliac tuberosity
• B. Iliac crest
• C. Greater trochanter
• D. Ischial tuberosity

Answer: (A)

Locating pelvic landmarks involves matching the name to the exact spot on the ilium. The iliac tuberosity is a roughened area on the posterior aspect of the ilium, along the iliac crest, where the sacroiliac ligaments attach. The name itself points to that specific patch on the ilium, distinguishing it from other features. Why this is the best fit: the term designates the particular rough area on the ilium used for ligament attachments, not the outer border of the bone (iliac crest), a feature on the femur (greater trochanter), or a sit-bone on the ischium (ischial tuberosity). The other terms refer to different structures, whereas the iliac tuberosity names the exact iliac landmark in question.
