Scoliosis is a medical condition characterized by an abnormal, sideways curvature of the spine that typically occurs in a "C" or "S" shape. While often identified during adolescence, scoliosis can affect individuals of all ages and, in severe cases, may impact lung and heart function due to pressure within the chest cavity. What are the primary types of scoliosis? Clinicians classify scoliosis based on its underlying cause and the age of onset.

What is Scoliosis

Scoliosis is a medical condition characterized by an abnormal, sideways curvature of the spine that typically occurs in a "C" or "S" shape. While often identified during adolescence, scoliosis can affect individuals of all ages and, in severe cases, may impact lung and heart function due to pressure within the chest cavity.



What are the primary types of scoliosis?


Clinicians classify scoliosis based on its underlying cause and the age of onset. The most common form is Adolescent Idiopathic Scoliosis (AIS), which accounts for approximately 80% of cases where no specific cause is identified. Other classifications include:



  • Neuromuscular Scoliosis: Caused by underlying conditions like cerebral palsy or muscular dystrophy affecting muscle control.

  • Congenital Scoliosis: Present at birth due to abnormal spinal development in the womb.

  • Degenerative Scoliosis: Occurs in older adults as a result of wear and tear, such as disc degeneration or arthritis of the spine.



How common is scoliosis and who is affected?


Scoliosis is relatively common, affecting an estimated 2% to 3% of the population. While both boys and girls develop the condition at similar rates in mild forms, girls are significantly more likely to develop moderate to severe curves that require medical intervention. At DiseaseMaps.org, 127 people with scoliosis have already joined our community to share their experiences and support one another.



What is the underlying mechanism of scoliosis?


In idiopathic scoliosis, the exact mechanism remains a subject of ongoing research, though it is believed to involve a complex interplay of genetic factors, hormonal imbalances, and connective tissue abnormalities. Unlike postural imbalances caused by poor habits, true scoliosis involves a structural rotation of the vertebrae, which distinguishes it from simple spinal misalignment.
