The greater trochanter attachments include which muscle?

The greater trochanter attachments include which muscle?

• A. Gluteus maximus
• B. Gluteus medius
• C. Piriformis
• D. Tensor fasciae latae

Answer: (B)

The greater trochanter serves as a primary insertion site for hip abductors and lateral rotators, with gluteus medius being the classic muscle that attaches there. It originates from the outer surface of the ilium and inserts along the lateral aspect of the greater trochanter, making it a key muscle for hip abduction and pelvic stabilization during gait. Among the options, gluteus medius is the best match because its insertion on the greater trochanter is a defining feature of its role in hip movement. The other muscles listed either attach elsewhere on the femur or, in the case of piriformis, attach to the superior border of the greater trochanter, but the origin and primary functional association that textbooks emphasize for this landmark is gluteus medius.
