A.The various types of scoliosis are:

A.75% of the scoliosis are idiopathic.

A.Idiopathic scoliosis is one where the etiology is unknown, but, it is probably genetic and the mode of inheritance is complex. Routine evaluation of school children aged 10-14 years has shown an incidence of up to 12%. Smaller curves (up to 15 degrees) and at a younger age, the incidence is equal in males and females. Beyond the age of 10-11 years 80% of the significant curves are in females.

A.It represents 1% of the scoliosis. It is not associated with vertebral anomalies. Curves less than 37 degrees resolve spontaneously. Curves more than 37 degrees are known to progress and are often associated with plagiocephaly. These curves are treated by succession of plaster jackets till 3 years of age when a Milwaukee brace can be fitted. If curves are progressive inspite of bracing treatment in the form of fusion is performed.

A.This represents 10% of scoliosis cases. It is more common in girls and right-sided curves are common. Treatment is required in curves of more than 25-30 degrees.
