This type of levoscoliosis affects the thorax and lumbar spine. It usually occurs as an S-shape curvature of the spine. In this case, the spine usually curves to the right side. However, it is hard to treat this condition because it affects the upper and lower sections of the spine.
What is deep fascia?

What is Subscap?
