Where does the iliopsoas insert?

• A. Lesser Trochanter of the Femur
• B. Greater Trochanter
• C. Tibial Tuberosity
• D. Intertrochanteric Line

Answer: (A)

The iliopsoas inserts on the lesser trochanter of the femur. This tendon, formed by the joining of psoas major and iliacus, reaches the femur to provide powerful hip flexion and stability. The lesser trochanter is the classic insertion point because it’s positioned directly adjacent to the hip joint where pulling the femur upward maximally flexes the hip.

The greater trochanter, by contrast, is the attachment site for gluteus medius and minimus (and some other hip rotators), not the iliopsoas. The tibial tuberosity is where the quadriceps tendon attaches to extend the knee, and the intertrochanteric line is a bony ridge on the femur—not an insertion for the iliopsoas.
