Scoliosis a spine that could efficiently support bipedality with a lower risk of scoliosis. Genetic testing for AIS, which became available in 2009 and is still under investigation, attempts to gauge the likelihood of curve progression. Scoliosis Scoliosis is a medical condition in which a person's spine has a sideways curve. The curve is usually "S"- or "C"-shaped. In some, the degree of curve is stable, while in others, it increases over time. Mild scoliosis does not typically cause problems, while severe cases can interfere with breathing. Typically, no pain is present. The cause of most cases is unknown, but is
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
