The Natural History of Idiopathic Scoliosis: Understanding Progression and the Influence of Orthotic Treatment (module 1)

Consider Idiopathic Scoliosis as a scoliosis of unknown cause. Infantile Onset Idiopathic Scoliosis is unique because it can spontaneously resolve. Discuss the importance of RVAD (Rib Vertebra Angle Difference), as well as the Risser Sign, Peak Growth Age (PGA), and the Heuter-Volkmann Principle. Consider that the primary orthotic treatment goal is to alter the natural history of further curve progression, and ultimately, avoid the need for surgical correction.

Description
Consider Idiopathic Scoliosis as a scoliosis of unknown cause. Infantile Onset Idiopathic Scoliosis is unique because it can spontaneously resolve. Discuss the importance of RVAD (Rib Vertebra Angle Difference), as well as the Risser Sign, Peak Growth Age (PGA), and the Heuter-Volkmann Principle. Consider that the primary orthotic treatment goal is to alter the natural history of further curve progression, and ultimately, avoid the need for surgical correction. In EOS (Early Onset Scoliosis), the RVAD can be an excellent predictor of a progressive curve. Discuss AIS (Adolescent Idiopathic Scoliosis) and the more skeletally immature the patient, the larger the curve prior to PGA (the primary adolescent growth spurt), and the greater the risk for curve progression. The orthotist should aim to balance the need for reasonable in-brace corrections of a deformity with keen observation of the patient’s ability to tolerate a given design.
