Think of the low back and the hips as closely related, One usually affects the other. But we are focused today on the hip.
The 2 hips each connect on each side of the sacrum - the lowest part of the spine- by a large joint between these bones.
Some of us are just a little out of position in our bodies. The spine will curve a little to the right or left above the level of the hips. The reason is some minor twisting o the spine.
This twisting is called scoliosis. About 14 % of people may have this twist: a spine that is a little crooked.
This 14 % scoliosis causes no harm. Someone with scoliosis of 30 % or more has a serious problem.
This amount of twisting is easy to spot; it badly affects someone; it needs a different specialist for this amount of scoliosis. For most people, we are talking about spines that are pretty straight or nearly straight.
I was taught by Richard DonTigny, a brilliant physical therapist, that the reason for a little bit of scoliosis is because most often one hip is chronically slightly higher than the other when someone is standing.
