Scoliosis metal rods attached to a plastic or leather girdle, designed to straighten the spine. As a result of the constant pressure the brace inflicted on a patients' spine, it was particularly painful and inconvenient to wear due to physical limits it imposed. Wearing the brace was known to cause jaw pain, skin irritation, muscle pain and low self-esteem among patients. The 'Harrington rod' technique was the second major treatment for scoliosis to emerge and became the first significant surgical procedure to manipulate spinal positioning. This treatment was initially developed to treat paralytic scoliosis that resulted from the polio epidemic of
Scoliosis drawn perpendicular to the upper endplate of the uppermost vertebra involved and the lower endplate of the lowest vertebra involved. For people with two curves, Cobb angles are followed for both curves. In some people, lateral-bending X-rays are obtained to assess the flexibility of the curves or the primary and compensatory curves. Congenital and idiopathic scoliosis that develops before the age of 10 is referred to as early-onset scoliosis. Scoliosis that develops after 10 is referred to as adolescent idiopathic scoliosis. Screening adolescents without symptoms for scoliosis is of unclear benefit. Scoliosis is defined as a three-dimensional deviation in the
