Which muscle groups are involved in the lateral rotation of the thigh?

The gluteus maximus and the external rotators play a crucial role in the lateral rotation of the thigh. The gluteus maximus, being the largest muscle of the buttock, is primarily responsible for the extension and lateral rotation of the hip joint. In addition to the gluteus maximus, there are several key external rotators, including the piriformis, gemelli, obturator internus, and quadratus femoris, which collectively contribute to the lateral rotation movement.

This combination of muscles allows for the proper execution of lateral rotation during various activities and exercises, such as walking and pilates movements. The synergy between the gluteus maximus and the external rotators is vital for maintaining stability in the hip joint and ensuring efficient movement mechanics.

The other muscle groups listed do not primarily facilitate lateral rotation of the thigh. For instance, the rectus femoris and sartorius are mainly involved in flexing the hip and extending the knee, while the psoas and iliacus focus on hip flexion. The adductors and tensor fasciae latae are more involved in adduction and stabilization of the hip. Understanding the specific roles of these muscle groups highlights the importance of the gluteus maximus and
