Which muscle's insertion point is at the greater trochanter?

The gluteus minimus is the muscle that inserts at the greater trochanter, which is a prominent bony projection located on the upper lateral part of the femur. This muscle plays a significant role in hip abduction and medial rotation of the thigh. Its positioning allows it to contribute effectively to stabilization of the pelvis during walking and other activities.

The other muscles listed do not have their insertion point at the greater trochanter. For instance, the adductor magnus primarily inserts along the linea aspera of the femur and has a different function related to hip adduction. Similarly, the obturator externus inserts on the trochanteric fossa of the femur, which is situated somewhat lower than the greater trochanter. Lastly, the pectineus muscle inserts on the pectineal line of the femur, again in a different area from the greater trochanter. Understanding the specific insertion points and functions of these muscles is essential for assessing lower limb mechanics and designing effective sports massage techniques.
