Is kyphosis and scoliosis a form of arthritis?

No, kyphosis and scoliOSis are not forms of Arthritis. Kyphosis refers to an excessive curvature of the spine, while scoliOSis is characterized by an abnormal lateral curvature of the spine. Both conditions relate to structural abnormalities of the spine rather than joint inflammation or degeneration, which are typical of arthritis. However, they can sometimes be associated with arthritis-related conditions, but they are distinct diagnoses.
