9/22 Questions Flashcards
What is the more complete, accepted definition of scoliosis?
an abnormal lateral curve coupled with axial rotation
What are the classifications of scoliosis according to the scoliosis research society?
magnitude location direction etiology structural scoliosis non-structural scoliosis
What does 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 location of scoliosis infer?
the location of the vertebral segment forming the apex of the curve deviation
What does 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 are some of the classifications of scoliosis based on etiology?
congenital neuromuscular neurofibromatosis nerve root irritation idiopathic
What is the classification of scoliosis that is unique to the individual patient?
idiopathic scoliosis
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?
infantile
juvenile
adolescent
What is the age range for infantile idiopathic scoliosis?
from birth to 3 years old
What is the age range for juvenile idiopathic scoliosis?

What is the genetic factor associated with adolescent idiopathic scoliosis?
an autosomal dominant factor that runs in families
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
What is/are the characteristic(s) of occipitalization of C1?
the atlas may be partially or completely fused to the occiput
What is another way of implying occipitalization of C1?
atlas assimilation
