Q

what is the treatment for mechanical back pain?

A

REASSURANCE- dont worry gals its not serious!!

bed rest will lead to stiffening and spasms of the back so maintain normal function

PHYSIOOOOOŌ

Q

what drugs may be given if analgesia is not enough?

A

Gabapentin for neuropathic pain

21
Q

what is spinal stenosis?

A

when there is narrowing of the spaces within the spine which can put pressure on the nerves causing lower back pain and pain in legs when walking

22
Q

how is mechanical pain diagnosed?

A
  • clinical

- can do an Xray

23
Q

what condition can occur if an acute slipped disc presses on an exiting nerve?

A

sciatica! :0

24
Q

what is the gold standard diagnoses for acute disc tear?

A

MRI

25
Q

what does claudication mean?

A

-pain caused by too little blood flow to muscles during exercise

26
Q

what does intermittent claudication mean?

A

-the pain is not consistent, usually begins during exercise and ends with rest

27
Q

how old do patients who suffer from spinal stenosis tend to be?

A

> 60

28
Q

how does spinal stenosis usually present?

A
  • claudication (the distance is usually inconsistent)
  • pain is burning
  • pain is less walking uphill
  • pedal pulses are preserved
29
Q

what are pedal pulses?

A

pulses in feet

30
Q

what is treatment for spinal stenosis?

A

First line conservative:

  • physioooo!!
  • weight loss if indicated

Second line:
-decompression surgery

31
Q

investigations for spinal stenosis?

A

-MRI (excluder peripheral arterial disease)

32
Q

what is cauda equina syndrome?

A

-a rare and severe type of spinal stenosis where all of the nerves in the lower back (cauda equina) suddenly become severely compressed

33
Q

what usually causes cauda equina syndrome?

A

-a very large central disc prolapse

34
Q

how does cauda equina syndrome present?

A
  • bilateral sciatica
  • saddle anaesthesia (numbness around the sitting area and perineum)
  • altered urinary function
  • altered bowel function
35
Q

what are the investigations for cauda equina syndrome?

A
  • PR exam mandatory!!

- urgent MRI scan

36
Q

what is the management for cauda equina syndrome?

A

-emergency surgery

37
Q

what are some red flags for back pain?

A
  • back pain in younger patients (<20)
  • new back pain in older patients (>60)
  • constant
  • severe
  • worse at night
  • fever
  • night sweats
  • fatigue
38
Q

what is cervical spondylosis?

A

age related wear and tear affecting the spinal discs in neck

39
Q

how does cervical spondylosis usually present?

A

-slow onset of stiffness and pain in neck which can radiate locally to shoulders and occiput (back of head)

40
Q

what is the treatment for cervical spondylosis?

A

-physio and analgesics

41
Q

what conditions are related to cervical spine instability?

A
  • down syndrome

- rheumatoid arthritis

42
Q

what does the carpal tunnel contain?

A

-median nerve
4 x FDP (flexor digitorum profundus)
4x FDS (flexor digitorum superficialis
FPL (flexor pollicis longus)

43
Q

what can cause carpal tunnel syndrome?

A

-idiopathic

secondary to :

  • RA
  • pregnancy
  • diabetes
  • chronic renal failure
  • hypothyroidism
  • fractures around the wrist
44
Q

what special tests are done for carpal tunnel syndrome?

A

Phalen’s test (holding wrists hyperflexed

Tinel’s test (percussing over median nerve

45
Q

what is the treatment for carpal tunnel syndrome?

A

non-operative treatment:

  • wrist splints at night to prevent flexion in the fetal position
  • injection of steroids (2 at most)

Surgical:
-carpal tunnel decompression

46
Q

what is cubital tunnel syndrome?

A

-a condition that involves the compression of the ulnar nerve at the elbow behind the medial epicondyle

47
Q

how does cubital syndrome present?

A

-numbness, tingling and/or pain in the ring and small fingers, sometimes arm and part of hand too

48
Q

what special test can be done for cubital tunnel syndrome and how is it performed?

A

Froment’s test- patient is asked to make a strong pinch between the thumb and index finger, the examiner then attempts to pull it out their hand. If the thumb does not stay straight and then it suggests the patient has damage to their ulnar nerve
