Scoliosis - Structural Flashcards
(41 cards)
Define scoliosis
Any lateral deviation of the spine greater than 10 degrees from the vertical line of the spine
How many degrees must the angle be to qualify as scoliosis?
10 degrees
Sidebending and rotation are (not related, sometimes related, or coupled motions)
coupled motions
The vast majority follow type 1 or type 2 Fryette mechanics?
type 1
How is scoliosis named?
for the side of convexity; If the person is sidebent left they have a right scoliosis
Does all asymmetry require treatment?
No
List 3 common ways scoliosis presents
routine physical exam, sudden onset, trauma
Pain in scoliosis suggests…
that the scoliosis is due to pain (not scoliosis causing pain)
Scoliosis could be the result of…
fracture, spondylolisthesis, nerve entrapment, spinal cord impingement
During a physical examination what two static and one dynamic structural exams must be completed?
Static - mid-gravity, symmetry
Dynamic - forward bending (Adam’s test)
If a rib hump measures more than ______ degrees further evaluation is warranted.
7 degrees
Why is such a small degree of concern?
Can impair pulmonary ventilation
A neurologic deficit would be caused by scoliosis. (T/F)
False
Why would you get an MRI for an idiopathic scoliosis?
looking for conditions like syringomyelia, neurofibromatosis which can mimic idiopathic scoliosis
How would you rule out Marfan or Ehlers-Danlos syndrome?
examine extremities for arachnodactyly and joint laxity
List the curve patterns and typing.
C- shaped, S-shaped, complex; major, minor, double major
What must be considered in scoliosis management?
age, skeletal maturity, type of curve, severity of curve, duration of curve, complicating factors
What is the most likely cause of scoliosis in an infant? (0-3 years of age)
congenital (ex. hemivertibrae)
In juvenile cases (3-10) what percent are due to occult intraspinal anomaly?
20%;
If scoliosis appears in adulthood it is usually associated with what?
disease
How does the area of the scoliotic curve affect the treatment?
Thoracolumbar is the most severe and surgery is considered at 40 degrees. Thoracic at 55 degrees.
What 7 complicating factors need to be evaluated in the decision?
pulmonary compromise, cardiac compromise, neurologic compromise, progression of curve, degenerative spondylosis, pelvic distortion, collapse of curve
Curves greater than ____ degrees are at increased risk for shortness of breath.
50 degrees
Curves greater than ____ degree Cobb angle impair respiratory function and venous return.
70 degrees
