Q

Why do we keep patients who have a fracture of the vertebral column in a position of extension?

A

Because the Anterior Longitudinal Ligament can act as a splint.

16
Q

Where do disc herniations typically occur?

Why do they occur there?

A

Typically the Nucleus Pulposis ejects into the posteriolateral side of the disc of the lower lumbar vertebrae (L4-L5 especially)

Because the Posterior Longitudinal Ligament is narrow, there is no support on either side of it to the back of the disk (posteriolaterally). Also, since the lumbar discs are large, there is more movement that can incite a herniation.

17
Q

For any given two vertebrae of the cervical or lumbar regions, a prolapse will affect which of the two vertebrae’s spinal nerve?

(Eg, there is a prolapse of C1 and C2, which nerve is affected?)

A

The second one.

(C2’s spinal nerve will be affected)
