Mechanical load from the gluteus maximus may, on the other hand, affect the morphology of the proximal femur, similar to how quadriceps determines the size and shape of the tibial tuberosity, and thereby the shape of the third trochanter.
The gluteus maximus muscle exerts a mechanical force on the proximal femur, which may similarly impact its shape as the quadriceps does on the tibial tuberosity, ultimately affecting the third trochanter's form.
