1

What type of joints are facet joints?

Synovial

2

What is the purpose of spinal curvature?

To aid posture and balance

3

Which two curves of the spine are examples of lordosis?

  1. Cervical
  2. Lumbar

4

Which two curves of the spine are examples of kyphosis?

  1. Thoracic
  2. Sacral

5

Where does disc prolapse most commonly occur?

  1. L4/5
  2. L5/S1

6

Lifing a heavy object may cause tear of what part of the intervertebral disc?

Annulus fibrosis

7

Why is MRI not diagnostic for disc pain?

Many people have bulging discs, yet are asymptomatic

8

What is the tip of the spinal cord called and at what vertebral level is it found?

Conus medullaris

L1

9

When does most disc prolapse settle by?

Within 3 months

10

Nerve root compression can cause what?

Radiculopathy which involves pain down the sensory distribution (dermatome) of the nerve root.

This may also result in muscle weakness and reduced reflexes

11

Why does spinal stenosis cause radiculopathy?

Osteophytes form and can compress the nerve roots

12

In spinal stenosis, there may be pain on walking, what is this called?

Neurogenic claudication

13

Where do sensory neurones exit the spinal cord?

At the dorsal root ganglion

14

Where do motor neurones exit the spinal cord?

Anterior grey horn

15

Anterior and posterior dorsal root pass through what after exiting the spinal cord?

Intervertebral foramen

16

What is cauda equina syndrome?

It involves pressure on all lumbosacral nerve roots including sacral nerve roots which supply the bladder and bowel

Signs include:

  • Bilateral lower motor neurone signs
  • Bladder and bowel control lost
  • Saddle anaesthesia
  • Loss of anal tone

17

What is a chance fracture?

When a fractured vertebrae causes disruption of the posterior ligaments 

This may require surgical stabilisation

18

What is the treatment for mechanical back pain?

Not usually surgery

  • Anagesia
  • Physiotherapy
  • Chiropractor
