Lesser trochanter attachments include which two muscles?

• A. Psoas major and Iliacus
• B. Iliopsoas
• C. Pectineus
• D. Rectus femoris

Answer: (A)

The lesser trochanter is the insertion site for the iliopsoas tendon, formed by the joining of two muscles: psoas major and iliacus. Psoas major originates from the lumbar spine, while iliacus comes from the iliac fossa; they merge and attach to the lesser trochanter, making them the primary hip flexors. The other options don’t attach at the lesser trochanter: pectineus inserts along the pectineal line of the femur, and rectus femoris inserts via the quadriceps tendon to the patella and tibial tuberosity, not the lesser trochanter.
