Types of Structural Scoliosis Idiopathic scoliosis 80% 1.Infantile <3yrs 2.Juvenile 4-9 yrs 3.Adolescent >10yrs (Most common) Scoliosis due to known causes 20% 1. Osteopathic : due to Congenital vertebral anomalies. Rare but dangerously progressive 2. Neuropathic : due to asymmetrical muscle weakness (e.g. in cerebral palsy and Poliomyelitis) 3. Myopathic : seen in the rare muscular dystrophies 4. Neurofibromatosis : associated with severe deformity

Patterns of Idiopathic Scoliosis A. Infantile thoracic : 60% male 90% convex to the left Associated with ipsilateral plagiocephaly (Oblique lateral deformity of the skull ) May be resolving or progressive(severe) A. Adolescent thoracic : 90% female 90% convex to the right Rib rotation exaggerates the deformity 50% develop curves of greater than 70 ˚
