1
Q

back pain is the leading cause of disability for?

A

<45 years

2
Q

what is the lifetime prevalence of back pain?

A

50%-80%

3
Q

what are the major cause of back pain?

A

non-specific idiopathic lumbar sprain (70%); degenerative disk disease; disk herniation; osteoporosis; spinal stenosis

4
Q

how many total vertebra are there?

A

7C; T12; L5; 5 sacral (fused); 4 coccygeal (fused)

5
Q

what are the major components of the vertebrae:

A

Body; Pedicles; Facets; Lamina; Spinous and transverse processes

6
Q

what composes a spinal segment?

A

The intervertebral disk; the vertebrae above and below that disc; spinal nerve

7
Q

structures in the back that may cause back pain have to have what?

A

they must be capable of causing pain (innervating pain fibbers/sensors)

8
Q

what are some biological changes that occur with disc degeneration? Specifically what happens to water content in the Nucleus pulposus?

A

It Decreases

9
Q

what are some biological changes that occur with disc degeneration? Specifically what happens to collagen content in the Nucleus pulposus?

A

increase in collagen

10
Q

disc degeneration occurs as a result of? And it results in?

A

Disc degeneration occurs as a result of intrinsic degradation and results in biomechanical changes which predispose to injury and pain

11
Q

can you get a desk herniation with out the degeneration?

A

no degeneration is a necessary prerequisite for herniation

12
Q

in a desk herniation what happens?

A

Generally Defect in the annulus allows the herniation of the nucleus; can be complete or partial (bulge or protrusion)

13
Q

The symptoms of a herniated disk are due to?

A

injury to the annulus/disk (leads to back pain); pressure from the herniated disk on the nerve root (lead to neurological deficit); mechanical and biochemical stimulation of the spinal cord (leads to referred pain down the leg)
