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).
Like all other joints, the muscles help provide support in addition to creating motion. If the muscles of the hip and tight/weak it can cause issues to arise at the ankle, knee, back as well as at the hip.
Muscles of greater significance are:
Tensor Fascia Latae
This muscle runs from the flare of the hip bone (ilium) all the way down to the knee. Tightness of this muscle can cause increased pressure and friction over the hip itself (greater trochanter) and the underlying bursa resulting in hip pain (tendonitis or bursitis). It can also lead to pain in the knee and or outer thigh.
This is one of the quadricep muscles that runs from the knee to the top of the pelvis. This muscle is highly used (trained by runners and kickers) for it helps extend the knee and flex the hip. Tightness and/or weakness in this muscle can lead to back, hip or knee pain.
The bursa are those fluid filled sacs that are located between structures to help prevent friction; however, if the overlying muscles are tight the bursa can become irritated and inflamed causing pain (bursitis). Busitis pain is often located on the outside of the hip. If the bursa is inflammed you will be recreate the pain by pressing on it.
