What is Scoliosis? Scoliosis is a lateral spinal curvature in the frontal plane that is identified by the persistent lateral deviation of several vertebrae from the line of gravity in one or more regions of the spine. Types of Scoliosis: Curves can be divided into two categories: functional curves and structural curves. Functional curves are referred to as nonstructural curves because they can be resorted around if the underlying cause is addressed. These curves are the result of imbalances that can be fixed, like an imbalance in leg length or a muscle spasm. As the name suggests, Structural curves involve modifications to the bone and soft tissue structures. Idiopathic Scoliosis: Infantile (0 to 3 years), juvenile (4 to 10 years), and adolescent (older than 10 years) idiopathic scoliosis are classified according to the age at onset. Up to 4% of schoolchildren around the world are affected by the most common type of scoliosis, called adolescent idiopathic scoliosis. Researchers hav
