IVT
adolescent idiopathic scoliosis
The most common form of scoliosis, developing during adolescence without known cause, requiring monitoring for progression during growth.
Full Definition
A three-dimensional spinal deformity that develops during adolescence (typically ages 10-18) without an identifiable underlying cause. This condition affects approximately 2-3% of adolescents and is more common in girls than boys. The curvature typically progresses during periods of rapid growth, making regular monitoring essential. Treatment depends on curve magnitude, skeletal maturity, and progression risk, ranging from observation to bracing to surgical correction.
Usage
Usage note: Often abbreviated as AIS; distinguish from other types of scoliosis by noting the idiopathic nature and age of onset.
