Orthopedists, who treat both bone and joint injuries as well as other conditions such as scoliosis and kyphosis, can often correct these curvatures when they occur in preteens. For the elderly, accumulated spinal injuries and diseases like osteoporosis can also lead to curvatures of the spine, which are treated symptomatically and may involve restorative procedures.
