progressively straighten the foot and surgical correction for severe cases.

Spinal Disorders

Chronic inflammatory disease of unknown origin that first affects the spine and is

characterized by fusion and loss of mobility of two or more vertebrae; also called

rheumatoid spondylitis

Treatment includes nonsteroidal anti-inflammatory drugs and, in advanced cases of a

badly deformed spine, surgery.

Increased curvature of the thoracic region of the vertebral column, leading to a
