Flashcards in Abnormal Curvatures of the Spinal Column Deck (20)
What are the classifications of scoliosis according to the Scoliosis Research Society?
- structural scoliosis
- non-structural scoliosis
What does the magnitude of scoliosis refer to?
the length and angle of the curve deviation on x-ray
What is often used to measure the magnitude of scoliosis?
the Cobb method
What does the location of scoliosis infer?
the location of the vertebral segment forming the apex of the curve deviation
What does the direction of scoliosis refer to?
the side the convexity of the curve will bend toward
What does etiology of scoliosis mean?
the cause of the scoliosis
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
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
What are some classifications of scoliosis based on etiology?
- nerve root irritation
What does idiopathic scoliosis infer?
- the scoliosis is unique to the individual
- it has no known cause
What is the incidence of idiopathic scoliosis in the population?
1-4% of the population
Based on age of onset, what are the types of idiopathic scoliosis?
What is the age range for infantile idiopathic scoliosis?
from birth to 3 years old
What is the age range for juvenile idiopathic scoliosis?
from 3 years old to 10 years old
What is the age range for adolescent idopathic scoliosis?
over 10 years old
Identify the curve direction, location, gender bias, and incidence of infantile idiopathic scoliosis.
- left thoracic
- less than 1% incidence
Identify the curve direction, location, gender bias, and incidence of juvenile idiopathic scoliosis.
- right thoracic
- females over 6 years old
- 12-21% incidence
Identify the curve direction, location, gender bias, and incidence of adolescent idiopathic scoliosis.
- right thoracic or right thoracic and left lumbar
- 80% incidence
What is the genetic factor associated with adolescent idiopathic scoliosis?
an autosomal dominant factor that runs in families
