What is the best treatment for curvature of the spine?

Depends on several. Scenarios. If no symptoms & the curve is not big in adult, no treatment needed. In general, exercise, weight control, not smoking & adequate vitamin d & calcium intake are important for spine health. If curve is 50 degrees or greater or if it involves the lumbar spine, there is a higher risk of progression & need for surgery. For a child, observation, bracing & rarely surgery are options.
