Scoliosis is a lateral (sideways) curvature of the spine ≥10° (Cobb angle), often with vertebral rotation. It affects 2–3% of adolescents.
Classification
- Idiopathic (80%): No known cause; adolescent idiopathic scoliosis (AIS) most common.
- Congenital: Vertebral malformations present at birth.
- Neuromuscular: Secondary to cerebral palsy, muscular dystrophy, etc.
- Degenerative: Adult-onset from disc/joint degeneration.
Severity & Management
| Cobb Angle | Severity | Typical Management |
| 10°–25° | Mild | Observation, physical therapy, bracing if progressing |
| 25°–40° | Moderate | Bracing (if growing), PT, monitoring |
| >40°–50° | Severe | Surgical correction (spinal fusion) often indicated |
Key Points
- Genetic predisposition + environmental factors likely contribute.
- Screening (Adam's forward bend test) during growth spurts.
- Early detection improves brace efficacy.
- Most curves do not require surgery.
