Q

Sometimes back pain is very persistent and can come back frequently

What are the ways to relieve back pain?

A

Stay as active as possible and try to continue daily activites- VERY important as resting makes it worse

Try exercises and stretches for back pain, also other activities like walking, swimming yoga and pilates can help

Take antiinflammatory drugslike ibuprofen- check it’s safe for you and ask a pharmacist

Use hot or cold compression packs for short term relief: a hot water bottle or frozen veg wrapped in cloth can help

Try to stay positive and optimistic- recognise your pain will get better

Q

what are the features of non-specific or mechanical back pain

A

It gets better or worse depending on position

Often worse when moving- however do not avoid moving your back (it’ll make it worse)

Can develop suddenly or gradually

Maybe result from poor lifting or posture or no apparent reason

May be caused by minor injuries such as sprains (pulled ligament) or strain (pulled muscle)

Associated with stress or being run down

Gets better within a few weeks

Q

what are the features of nerve treatment? when can it be used?

A

Radiofrequency denervation can be used if:

  • you have back pain for a long time
  • Severe or moderate pain
  • pain is thought to originate from joints in the spine

Needle is inserted into nerves that supply the affected joints and radio waves are sent through needles to stop the nerves sending pain signals (by heating it)

it is done under local anaesthetic and you can go home on the same day

Q

what are the types of treatment not recommended for back pain according to NICE

A

Belts, corsets, foot orthotics and shoes with “rocker” soles

Traction – the use of weights, ropes and pulleys to apply force to tissues around the spine

Acupuncture

Therapeutic ultrasound – directed at back

Transcutaneous electrical nerve stimulation (TENS) – where a machine is used to deliver small electrical pulses to your back through electrodes (small sticky patches) attached to your skin

Percutaneous electrical nerve stimulation (PENS) – where electrical pulses are passed along needles inserted near the nerves in the back

Interferential therapy (IFT) – where a device is used to pass an electrical current through your back to try to accelerate healing

Painkilling spinal injections (although these can help if you have sciatica

25
Q

One of the treatments for back pain is taking NSAIDS, but what other painkillers can you take if NSAIDS are not suitable for you

A

Codeine may help- use only a few days as it can lead to addiction

Don’t use paracetamol on it’s own. can use together with codeine

Muscle relaxants can be prescribed if you have back spasms

  • E.g diazepam
26
Q

What are the side effects of muscle relaxants od diazepam and what precautions should you take

A
  • Drwosy
  • dizzy
  • blurred vision

Do not drive, cycle or operate machinery if you have these S/E

27
Q

why should wrap a ice pack in towel before applying to pain area

also what other method can you use for hot or cold packs

A

prevent cold burns

You can alternate between using hot and cold packs

28
Q

what exercises can help you stay positive

A

10 stress busters

Breathing exercises for stress

29
Q

what should always be used alongside manual therapy?

what new technique may help but hasn’t been recommended by NICE yet

A

Other measures like exercise

New technique- Alexander Technique

30
Q

what are the features of CBT and what should you offer people who have been in pain fro a long time

A

it can help by changing how you think about your condition

This is because how you think about your pain can make it worse

Offer a combination of CBT, group exercises, exercises, relaxation - specialist treatment programme

31
Q

what are the back stretches that can help with back pain

A

Kneeling stretch exercise- warm up

Back extension exercise

Knees to the chest exercise- stretches the back into bent flexed position to stretch ligament and muscles.

Knee rotation- all about movement into lower spine

Superman exercise- tone up the muscles to keep spine stable

Bridging exercises

32
Q

what is cauda equina syndrome and what are the causes?

A

this is a medical emergency - There is a compression of spina cord in the dura at the cauda equina

Causes:

  • Commonly- prolapsed disc (posteriorly)
  • Other less common: infection and tumour

Can be quite difficult to diagnose in it’s earliest stages because back pain very common and CES is very rare

33
Q

Why is it important NOT TO MISS a diagnosis of Cauda equina syndrome?

what should you do if you suspect it

A

if its’s untreated, there would be permanent damage ot the spinal nerve roots in the cauda equina.

Pt can lose permanent loss of functions like: urinary and fecal incontinence.

Pt can sue for clinical negligence as they will not be able to function properly ( claims are large)

If you suspect it, REFER immediately (24hrs) to a neurosurgeon for decompression surgery

34
Q

why can CES claims be expensive?

A

cost of Degree of damage done from lack of care provided

Care costs and consequential losses make up the bulk of the rest.

Consequential loss could be due to loss of earnings over time especially if they have a high paying job

35
Q

what is the requirement for a CES claim to be successful

A

Claimant has to show that care from docotr fell below standard, i.e. a breach of duty

Claimant must also show that the breach has caused loss or damage (causation)

Both claimants and defendants will instruct independent experts to investigate these two aspects of a claim

36
Q

when might a CES claim result be small/negligible?

A

if pt has made good recovery with limited sequelae- claim will be small to reflect period of pain/suffering

If indepenedent expert evidence says the same level of injruy would occur in any event- hence it’ll be no/little compensation

  • i.e if delay is only a matter of hours
  • if Injury was already establised at time the patient saw the doctor
37
Q

Outline the stattistics of the claims of CES faced by the MDU?

A

between jan 2005 and Apr 2016;

  • MDU paid £ 8 mil in total compensation Most of which were under 100k.
  • 12% were 500k
  • MDU also paid 4.5 mil in claimant solicitor fees
38
Q

State what percentage of CES claims were in Out of hour GP and explain what it means

A

10% of all claims related to out of hours calls or telephone call

only 1/3 was settled

This means it isa very diffuclt in assessing CES in out of hours setting

39
Q

what are the red flag symptoms for CES

A
  • Pain that radiates below the knees bilaterally (on rare occasions this can be unilateral).
  • Bilateral lower limb numbness or weakness.
  • Numbness either side of the buttocks and saddle area.
  • Bladder and/or bowel disturbance (including difficulty passing urine, poor stream, loss of sensation).
  • Diffulty innitaitng micturition, if untreated can lead to urinary overflow
  • Erectile dysfunction.
  • Loss of anal tone or impaired sensation on per rectal (PR) examination.
40
Q

what are the MDU top tips to maximise pt safety and reduce claims

A

Conduct a full examination to establish the likely cause of the back pain and make a record that this has been done.

Consider any red flags.

If red flags are present, IMMEDIATELY Call the orthopaedic or neurosurgical specialist for immediate advice, or if this is not available, arrange for the patient to be admitted to hospital via the emergency department.

If no red flags are present, make a record in the notes to demonstrate you have actively considered the condition.

If, after the assessment, the patient is being managed as having simple mechanical back pain, make sure you give appropriate safety netting advice.

This should include advising the patient of the red flag symptoms and the importance of seeking urgent medical attention if these appear.

Again, try to make a record in the notes of the specific safety netting advice that has been given.

41
Q

Why may patients with kidney or pancreas or aortic problems present with back pain|?

A

Referred pain

This means that visceral afferent fibres from organs can synpase in the same dorsal root ganglion as one from skin in the back.

The brain can confuse the signals

42
Q

Explain the type or causes of back pain from the different zones in the diagram.

Explain it’s features

A

Zone A- Mechanical back pain:

  • mechanical problem of the back: could be vertebrae or lumbar muscles
  • Too much strain or maybe infection

Zone B- Spinal cord comprresed

  • Commonly caused when IV disc hernate centrally and affect the spinal cord in the dura.
  • Symptoms are bilateral and multiple systems of the body are affected.

Zone C- radiculopathy

  • Commonly caused when IV disck herniate posteriorly and laterally and impinge on the nerve roots.
  • Symptoms are unilateral and affect specific parts of the body. Affect both sensory and motor axons
43
Q

how do you manage radiculopathy?

A

You manage it conservatively as it tends to get better on it’s own

You advice pt to rest, massge and exercise

On occasions you can do minimally invasive surgery- this is dependent of signs and sympotms and severity of it.

44
Q

outline the development of the spinal cord.

A

In adult spinal cord stops at L2

45
Q

Cauda equina is rare (0.4% of ppl with back pain)

what are it’s symptoms and what is the definite method of diagnosing cauda equina syndrome?

A

Bilateral symptoms:

  • Loss of anal tone, sensation
  • loss of bladder control; unable to pee
  • Bilateral leg weakness (maybe one) - can also present with foot drop and hence you’d notice a limp whilst walking
  • Reduced perinaeal sensation
  • Sexual dysfunction

Only MRI can diagnose it

46
Q

what is the most common site for disc herniation and how can that lead to inability to urinate

A

Common site- L4/L5 and L5/S1

So anything below this site is impaired. Especially PNS to urinary bladder

The S2-S4 PNS to urianry bladder via pelvic/sacral nerve is stopped and therefore you cannot relax internal urinary sphincter

However the the T12-L3 SNS to bladder is working- it promotes detrusor relaxation.

47
Q

Explain how Urinary retention can lead to incontinence as CES worsens

A

Patient are unable to pee as baldder fulls.

Pressure builds up in bladder and overcome the constriction of the urinary sphincter

it leads to overflow bladder incontinence (very bad prognosis)

I.e the somatic, SNS and PNS are all affected

N.B. it is better to find a pt with CES who cannot pee than one with incontinence

48
Q

it is important to phrase questions in a good way when asking about red flag symptoms- pt may be confused/embarrased

For each red flag symptom- outline how you would ask it to the pt

A

loss of feeling/pins and needles between inner thighs

Do you feel anything different when you try to pee

Do you feel anything different during sex (loss of sensation)

Loss of sensation when you move your bowels

Altered feeling when using toilet papaer to wipe yourself

Change in ability to achieve an erection or ejaculate.

TELL YOUR pts WHY you are asking these questions

49
Q

Can you diagnose CES by history alone?

A

No you need a definite MRI that shows disc herniation in order to diagnose it

50
Q

CES is normally an acute issue; give an explanation as to how it may present as acute on chronic

A

Firstly, back pain is very common (80%) and therefore the causes are unrelated. i.e old back pain is mechanical and new pain is CES

Secondly, the size of herniation on disc may be small at first causing radiculopathy. Then the disc gets bigger and may herniate more centrally - leading to acute on chronic CES

51
Q

Explain the guidelines for documentation and why you need to document everything clearly, accurately and legibly

A

Document cleraly, accurately and legibly at the same time as event OR very soon afterwards

Keep records with personal information about pts, colleague etc in line with existing relevant law

Clinical records should contain:

  • Relevant postiive and negative clinical findings
  • decisions made and actions agree and who is making and agreeing the actions
  • info given to pts (red flags)
  • any drugs prescribed/ investigation/treatment
  • who is making the record and when
52
Q

ExplaIn the SNS mechanism for micturition

A

SNS efferent originate in lateral gray column of spinal chord betwenn T11- L2 or (L1-L3)

The long post–ganglionic fibres run with hypogastric nerve and synapse with alpha and beta recpetors in detrusor muscle wall, internal sphincter

Beta - causes relaxation of detrusor muscle with filling

alpha - causes tonic contraction of internal sphincter

53
Q

draw the gross pathway for the spinothalamic and dorsal column leminiscal pathway

A
54
Q

Draw out the whole pain pathway in the spinothalamic tract from relevant receptors to primary somatosensory pathway

A

2 types of pain

Sharp pain- carried by fast neo spinothalaic tract (A delta fibres)

  • Extra Synapses at SII region then insula

dull pain- slower paleospinothalamic tract. (c-fibres)

  • Places of extra synapses are: Reticular formation, sensory cortex, cingulate cortex and amygdala

There is a muscle relfex at the dorsal horn in this pathway.

55
Q

In the pain pathways, what are the physiological response produced when the axon synpase at the following:

  • Reticular formation
  • Amygdala
  • Cingulate cortex
  • SII region
  • Insula
A

Reticular formation- Arousal

Amygdala- fear

Cingulate cortex- aversion

SII region- visual integration

Insula: vasocosntriction, sweating and increase in pulse rate

56
Q

what are the different types of touch receptors and draw the pathway for the dorsal column medial- leminiscus tract

A

Meissner’s corpuscles

Ruffini corpsucles

Pacinian corpuscles

Merkels’ discs

Free nerve endings

57
Q

what is the affective neuroscience theory

A

Pain and sensation in some areas of the brain can trigger a physiological and motivational output

58
Q

what are the classifcation of noiciceptors and describe any relevant details including where they are found and their stimuli

A

Mechanorecptor- found in plasma membrane of high threshold free nerve ending

  • sensitive to stretch as it undergoes conformational change when force is applied to it

Themoreceptor- change to temp

Chemoreceptor: initiates action potential in response to cytokines like histamine, etc hence thats why there;’s pain in inflammation

59
Q

Walk me through the surgical procedure for CES intervention

A

Typical microdiscectomy

A part of lamina is diseected just above the site of herniation and then you cut through ligamentum flavum

You reflect the spinal cord/nerve.

You go through the posterior longitudinal ligament.

Use appropriate tools to remove all the herniated disc material. you know that all the disc is material is removed when the spinal nerves is no longer taut
