Idopathic scoliosis is the most common form of spinal deformity seen. By definition, it is lateral curvature of the spine occurring in an otherwise healthy child, for which no recognizable cause exists. It is divided into three categories depending on the age at which the curve is first detected:
- Infantile idiopathic scoliosis - when the cure occurs before the age of 3 years.
- Juvenile idiopathic scoliosis - first appears between the age 3 and 10 years.
- Adolescent idiopathic scoliosis - the most common type and is first detected after puberty i.e. after 11 years.
Adolescent idiopathic scoliosis is the most common type of spinal curvature. It occurs around the onset of puberty in otherwise healthy boys and girls. It is more common in girls.
