Classification
Scoliosis can be classified into congenital scoliosis (due to failure of vertebral formation or segmentation of affected vertebrae), idiopathic scoliosis(when the cause is not known) or neuromuscular scoliosis (due to loss of muscle strength or voluntary muscle control).
- Congenital scoliosis is subdivided based on radiological finding, combined structural component involved and 3-D CT.
| Complete failure - hemivertebra, butterfly vertebra | |
| Failure of formation | Partial failure - wedged vertebra |
| Unilateral failure - longitudinal failure | |
| Failure of segmentation | Bilateral failure - block vertebra |
| Miscellaneous | Formation and segmentation mixed failure |
| Anterior component | Posterior component |
|---|---|
| Hemivertebra (hemipedicle) | Fully segmented hemilamina |
| Semisegmented hemilamina | |
| Spina bifida | |
| Bilamina (complete or incomplete) | |
| Butterfly lamina (bipedicle) | Wedged lamina |
| Spina bifida | |
| Lateral wedged vertebra (bipedicle) | Wedged Lamina |
| Type 1 | Solitary simple congenital malformation (unison)
|
| Type 2 | Multiple simple anomalies (unison)
|
| Type 3 | Complex anomalies (discordant)
|
| Type 4 | Segmentation failure only |
- Idiopathic scoliosis may be further classified into three types based on age of onset.
- infantile idipathic scoliosis (birth to 3 years)
- juvenile idiopathic scoliosis (4 to 9 years)
- adolescent idiopathic scoliosis (10 to 20 years)
