-Scoliosis is a sideways curvature to the spine (see Figure 9 below), associated with pain but not neurological impairment.
-Scoliosis should be suspected with leg length discrepancies of 2.2 cm or greater.
-The abnormal spinal curve of scoliosis is measured on plain X-rays. The measurement is called a Cobb angle. Scoliosis may be considered present with abnormal curves greater than 10 degrees. Mild cases have angles less than 30 degrees.
-Angles of 20 degrees or less are usually produce no symptoms. Bracing is prescribed for angles over 20 degrees. Curves over 40 degrees may produce neurological abnormalities such as sensory loss and weakness. Small curves of less than 30 degrees in childhood are not likely to get worse during adulthood, while more severe curves may continue to progress. Surgery with permanent rod implantation and fusion is indicated with curves greater than 45 degrees.
-Claimants with curves 60 degrees or more require spirometry for restrictive lung disease (decreased vital capacity).
-Heart failure may occur from scoliosis when abnormal curves are markedly severe at 100 degrees or more.
