The greater sciatic notch is a large notch in the hip bone that allows the passage of the sciatic nerve and vessels from the pelvis to the lower limb. It also provides space for the attachment of important muscles, such as the piriformis and gluteus maximus, that play a role in stabilizing and moving the hip joint. Overall, the purpose of the greater sciatic notch is to facilitate movement and provide support for the structures that pass through it.
