Q

Summary of SACD

A

Demyelination of fibres of dorsal and lateral areas of spinal cord from B12 deficiency —>

Mix sensory and UMN signs

Reduced sensation, vibration, proprioception, ataxia, spastic loss of power and upgoing plantars - babinskis sign

B12 deficiency affects distal limbs in length dependent pattern

Q

Red flag questions for backpain

A
  • Sciatica (pain radiating down back of leg)
  • Leg weakness
  • Saddle paraesthesia (numbness or changed sensation to the perineum)
  • Urinary symptoms (difficulty initiating urination, reduced sensation of urination, urinary incontinence)
  • Bowel symptoms (faecal incontinence)
  • Recent trauma
  • Fevers/Night sweats
  • Weight loss
  • Pain that disturbs sleep
  • History of intravenous drug use
  • Osteoporosis
  • Prolonged use of steroids (raises risk of osteoporosis)
17
Q

Investigations for cauda equina

A

PR exam - loss of anal tone, reduced sensation
Post void bladder scan- retention - complete CE
Full spine MRI

18
Q

What is gold standard in cauda equina

A

full spine MRI (within 1 hour preferable but not beyond 24)

19
Q

Symptoms of suspected cauda equina

A
  • Bilateral sciatica
  • Leg weakness
  • Saddle paraesthesia
  • Bladder disturbance
  • Bowel disturbance
20
Q

Complete auda equina symptoms

A
  • Urinary retention
  • Overflow urinary incontinence
  • Loss of anal tone and peri anal sensation
  • fAECAL INCONTINENCE = LATE SIGN
  • sADDLE PARAESTHESIA - WIDESPREAD and complete
21
Q

Incomplete cauda equina syndrome

A

Subjective reduced urination sensation
Difficult passng, poor stream
Reduced urge to void bladder
Anal tone/sensation may be normal
Pathcy unolateral paraesthetisa saddle
Reduced power and reflexes, sciatic pain

22
Q

Causes of cauda equina

A

Disc herniation
Haematoma
Malignancy
Spinal abscess
Stenosis Vertberal fracture

23
Q

Treatment of cauda equina

A

Emergency surgery in next 48 hours
Laminectomy, dicectomy
High dose steroids - reduce swelling and oedema
Analgesia #Bloods - group and sace and coag
Urethral catherer if needed
Monitor for deterioration

24
Q

Complications of cauda equina

A

Long term pain, motor function, badder/bowel disturbance, sexual dysfunction

25
Q

Differentials for bilateral leg weakness

A
  • Guillian Barre
  • Cauda equina
  • Stroke (unilateral)
  • Transverse myeltiis
  • Epidural abscess
  • Off legs
  • Spinal cord compression
26
Q

What tract controls voluntary movement

A

Down corticospinal tractn

27
Q

Which tract controls pain and temp

A

Lateral spinothalamic tract

28
Q

Wich tract ontrols vibration and proprioception

A

Dorsal column

29
Q

What does anterior spinal artery syndrome cause

A

Corticospinal and lateral spinothalamic affeted
Causes Increased tone. Reduced power in hip flexion. Reduced pain sensation. Reduced temperature sensation. Normal joint position sense. Normal vibratory sensation.

30
Q

What is anterior spina, artery sundrome

A

Anterior 2/3 cord affected by stroke to areterial supply to cord
Treat with anticaog
Poor prognosis
