18
Q

Based on the age of onset, what are the types of idiopathic scoliosis?

A

infantile, juvenile, and adolescent

19
Q

A

from birth to 3 years old

20
Q

What is the age range for juvenile idopathic scoliosis?

A

from 3 years old to 10 years old

21
Q

What is the age range for adolescent idopathic scoliosis?

A

over 10 years old

22
Q

Identify the curve direction, location, gender bias and incidence of infantile idiopathic scoliosis

A

left thoracic, male, less than 1% incidence

23
Q

Identify the curve direction, location, gender bias and incidence of juvenile idiopathic scoliosis

A

right thoracic, females over 6 years old, and 12%-21% incidence

24
Q

Identify the durve direction, location, gender bias and incidence of adolescent scoliosis.

A

right thoracic or right thoracic and left lumbar, females, and 80% incidence

25
Q

What if the genetic factor associated with adolescent idiopathic scoliosis?

A

an autosomal dominant factor the runs in families

26
Q

What is the relationship between curve deviation, incidence, and curve worsening?

A

the greater the deviation, the lower the incidence, and the more likely to worsen
