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 force on the proximal femur, which can affect its shape similarly to how the quadriceps influences the tibial tuberosity, ultimately impacting the third trochanter's form.
