The femur is the bone that makes up the hip; however, when assessing the hip medical practitioners will consider the pelvis and low back as well. So the bones considered are the femur, the low back, and the pelvic. When you touch the outside of your hip you are actually touching the “greater trochanter”.
As we age, we can have the on-set of hip arthritis. Pain associated with this is often “deep” and can refer to the inside of the hip (the groin).
