Answer 1

The Risser sign, an indication of bone maturity in the iliac apophysis

Question 2

Answer 2

The length and angle of the curve deviation on X-ray

Question 3

What is often used to measure the magnitude of scoliosis

Answer 3

The cobb method

Question 4

What does location of scoliosis infer

Answer 4

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

Question 5

What does direction of scoliosis refer to

Answer 5

The side the convexity of the curve will bend toward

Question 6

What does etiology of scoliosis mean

Answer 6

The cause of the scoliosis

Question 7

What is structural scoliosis

Answer 7

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

Question 8

What is nonstructural scoliosis

Answer 8

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

Question 9

What are some of the classifications of scoliosis based on etiology

Answer 9

Congenital
neuromuscular
neruofibromatosis
nerve root irritation
idiopathic

Question 10

What is the classification of scoliosis that is unique to the individual patient

Answer 10

idiopathic scoliosis

Question 11

What does idiopathic scoliosis infer

Answer 11

the scoliosis is unique to the individual, it has no known cause, unknown etiology

12-21% incidence

Question 17

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

Answer 17

Right thoracic or right thoracic-left lumbar
Females
80% incidence

Question 18

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

Answer 18

Left thoracic
males
less than 1% incidence

Question 19

What is the genetic factor associated with adolescent idiopathic scoliosis

Answer 19

An autosomal dominant factor that runs in families

Question 20

What is the relationship between curve direction, incidence and curve worsening

Answer 20

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