Spinal deformity conditions generally involve abnormal curvature of the spine. Scoliosis and kyphosis are types of spinal deformity conditions. The curves may result from degenerative changes, fractures, infection, malignancy or structural changes following spine surgery. Some types of deformity are due to the spine being misshapen as the person grows from childhood. Spinal deformity conditions may or may not cause pain. Pain in patients with a spinal deformity condition may arise from the curved spine compressing or irritating nerves, or from the facet or sacroiliac joints.
