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
Management of scoliosis would try to compensate for this in the effort to stand up straight. As the person aged, there would be increased wear and tear, early-onset arthritis, disc degeneration, muscular stiffness, and pain with eventual reliance on painkillers, further surgery, inability to work full-time, and disability. "Flatback" became the medical name for a related complication, especially for those who had lumbar scoliosis. In the 1960s, the gold standard for idiopathic scoliosis was a posterior approach using a single Harrington rod. Post-operative recovery involved bed rest, casts, and braces. Poor results became apparent over time. In the 1970s, an improved technique was
