Second most common type?

Second most common type?

• A. Juvenile idiopathic scoliosis
• B. Adolescent idiopathic scoliosis
• C. Degenerative scoliosis
• D. Congenital scoliosis

Answer: (A)

The main idea is how scoliosis is distributed by age and cause. Idiopathic scoliosis makes up the vast majority of cases, and within that group the adolescent-onset form is the most common. Juvenile onset idiopathic scoliosis is less common than the adolescent form but more common than other categories that aren’t idiopathic, such as degenerative scoliosis (which appears in adults due to spinal wear-and-tear) or congenital scoliosis (due to congenital vertebral anomalies and seen less frequently). Because growth and the timing of onset influence how curves progress and respond to treatment, recognizing that juvenile idiopathic scoliosis is the second most frequent type helps explain both prognosis and management in younger patients.
