Q

Chronic Pain

A

Nociplastic:
- Last beyond normal healing time after injury

  • Widespread pain (hyperalgesia / allodynia)
  • Results from neuroplastic changes to pain pathways: peripheral & central sensitisation, descending facilitation and dishinibition.

Q

Conditions of Central Canal Stenosis

A

Immediate medical/surgical referral.

Most often due to IVD

Q

Intervertebral Disc Disease

A
  • Degenerative
  • Prolapse & hernitation
  • Internal disc disruption
28
Q

Degenerative Disc Disease

A

Disc becomes less hydrated and thinner with age, lose capacity for shock absorption and become susceptible to tears in the pain sensitive outer annulus.

  • Normal part of ageing
  • Often asymptomatic
  • Diagnosis by MRI
  • Cause pain in middle age (30-50yrs)
29
Q

Intervertebral Disc Prolapse

A
  1. Protrusion or budge (posteriorly)
  2. Prolapse (nucleus contained)
  3. Extrusion (annulus fibrous disrupted)
  4. Sequestration (Free nuclear material)
30
Q

Mechanism of Intervertebral Disc Prolapse Injury

A
  • Repetitive mechanical twists such as bending and twisting (no breaks)
  • Fully flexed spine for repeated or long time (under load)
  • Forceful rotation
  • Heavy lifting
31
Q

  • Young to middle age (20-50yrs)
  • Rare in children or elderly
  • Male to female 2:1
  • Typically occurs suddenly but can develop gradually over weeks
32
Q

  • Hairy patch
  • Dimple in back
  • Fatty deposits
  • Port wine mark
50
Q

Facet Tropism

A

Asymmetry in the sagittal orientation of the facet joints.

  • May be associated with instability and degeneration
51
Q

Lumbarisation

A

S1 is not fully fused with sacrum (appears as 6 lumbar vertebras)

52
Q

Sacralisation

A

L5 is fully or partially fused to the base of sacrum
(can appear as 4 lumbars)

53
Q

Ankylosing Spondylitis

A

Form of inflammatory arthritis. Predominately effects the spine by creating inflammation of joints.

54
Q

Ankylosing Spondylitis affects what percentage of population?

A

About 1% percent of population

  • Male to female 2:1
