Scoliosis
Scoliosis is a medical condition in which a person's spine is curved from side to side. Although it is a complex three-dimensional deformity, on an X-ray, viewed from the rear, the spine of an individual with scoliosis may look more like an "S" or a "C" than a straight line...

 or other interventions.

Approximately 85-90% of patients initially diagnosed with AIS will never have their mild scoliotic curve progress to a magnitude that requires surgical treatment. The test results may be used to predict, with over 99% probability, when a mild scoliotic curve is unlikely to progress to the point of requiring surgical treatment. This knowledge can obviate the need for these patients to undergo numerous office visits and exposure to radiographic imaging over many years to monitor potential curve progression. The ScoliScore test is a powerful tool, which helps physicians predict spinal curvature through one test, accomplishing what was previously only possible through years of observation.

The ScoliScore test was developed by geneticists at Axial Biotech, Inc. in Salt Lake City and it is distributed commercially by DePuy Spine, a Johnson & Johnson

 company. It was made available in a few physicians offices in September, 2009, and will be commercially launched in 2010.

The genetic research behind the clinically validated ScoliScore AIS Prognostic Test began in 2003, as researchers explored the entire human genome searching for genes that were linked to Scoliosis. DNA samples from over 9,000 patients from 85 clinics worldwide were analyzed. The researchers identified 53 genetic markers (or mistakes in the DNA) that are linked to AIS.

Today, lab workers use special equipment to read each of those 53 genetic markers for all patients who take the ScoliScore test. The test results are given in a ScoliScore, a numerical value that corresponds to the likelihood of curve progression. Each ScoliScore falls into one of three categories, mild risk, intermediate risk, or severe risk of curve progression.
