1

What are the classifications of scoliosis according to the Scoliosis Research Society?

- magnitude
- location
- direction
- etiology
- structural scoliosis
- non-structural scoliosis

2

What does the magnitude of scoliosis refer to?

the length and angle of the curve deviation on x-ray

3

What is often used to measure the magnitude of scoliosis?

the Cobb method

4

What does the location of scoliosis infer?

the location of the vertebral segment forming the apex of the curve deviation

5

What does the direction of scoliosis refer to?

the side the convexity of the curve will bend toward

6

What does etiology of scoliosis mean?

the cause of the scoliosis

7

What is structural scoliosis?

- a more radical form of scoliosis
- it may worsen
- associated with structural deformities of the vertebra or intervertebral disc
- frequently has a fixed angle of trunk rotation

8

What is non-structural scoliosis?

- a mild form of scoliosis
- unlikely to worsen
- not associated with structural deformities of the vertebra or intervertebral disc
- lacks a fixed angle of trunk rotation

9

What are some classifications of scoliosis based on etiology?

- congenital
- neuromuscular
- neurofibromatosis
- nerve root irritation
- idiopathic

10

What does idiopathic scoliosis infer?

- the scoliosis is unique to the individual
- it has no known cause

11

What is the incidence of idiopathic scoliosis in the population?

1-4% of the population

12

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

- infantile
- juvenile
- adolescent

13

What is the age range for infantile idiopathic scoliosis?

from birth to 3 years old

14

What is the age range for juvenile idiopathic scoliosis?

from 3 years old to 10 years old

15

What is the age range for adolescent idopathic scoliosis?

over 10 years old

16

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

- left thoracic
- male
- less than 1% incidence

17

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

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

18

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

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

19

What is the genetic factor associated with adolescent idiopathic scoliosis?

an autosomal dominant factor that runs in families

20

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

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