Best practice (BMJ Nov 2012)
Acute Whiplash
Confirm accurate history for medico-legal
reasons
Neck pain, head pain,
Fatigue, dizziness, paraesthesiae, nausea, jaw
pain
MANAGEMENT?
Management
Reassurance about self-limiting
Early return to normal activities
Discourage rest and soft collars
Outlook varies with culture, payment for health
services, compensation
More pain, symptoms initial disability is assoc with
delay
Management
Analgesia
Physiotherapy
Yellow flags – intervene early
Correct erroneous beliefs
CBT
Pain clinic
Yellow flags (New Zealand Guidelines Group)
•
Belief that pain and activity harmful
•
Sickness behaviours like extended rest
•
Social withdrawal
•
Emotional problems e.g. depression anxiety and
stress
•
Work problems
Yellow flags (New Zealand Guidelines Group)
•
Problems with time off work
•
Compensation?
•
Overprotective family
•
Lack of support
•
Inappropriate expectations of treatment
Resist Chronicity?
Resist prescriptions
Resist investigations
Encourage normality
Diagnose co-morbidity (e.g. depression)
Do not corroborate poor prognosis
Continue education about behaviour / beliefs
Pain clinic early?

Worse at the end of the day
Radiates down both arms
Arms feel numb at times
Non – Specific neck pain
2% GP consultations
Prevalence in middle age, women > men
Point prevalence of 8%
Lifetime prevalence of about 50%
(clinical evidence 2008)
Non-specific neck pain
•
Varies with different activity – rest may aggravate OR rest may
relieve pain
•
Radiates on non-segmental distribution
•
May be sensory symptoms without signs
•
Varies with time
•
Related to
•
OR
poor posture
•
OR
overuse
•
OR
non of these
awkward movement
Examination of non-sp neck pain
•
Positional asymmetry – a change in the most
comfortable resting position
•
Unequal restriction in range of movement
(although this is common in degenerative
disease)
•
Tenderness in hypertonic muscles
•
Poorly localised tenderness
•
Localised areas of inc muscle tone? – nodules or
tender bands
Risk factors
• Workplace or workstation
• Duration of position
• Hand-arm vibration
• Twisting/bending of trunk
• Excessive use of pillows
Management < 4 weeks
Identify risk factors
Identify psychological factors
Imaging not usually required
Reassurance
Encouragement of activity and normality
One firm pillow in the hollow of the neck
Analgesia
Management > 4 weeks
As previously PLUS:

Pain clinic ?
Case Study 4
58 year old man – Scaffolder
1 month of increasing discomfort in neck
Radiation down left arm
Shakes left hand when holding things
Arm feels tight/numb
Cervical radiculopathy
Symptoms
Usually unilateral
Neck shoulder or arm in a dermatome
Sensory symptoms
Weakness
Pain or no pain
Nocturnal pain interfering with sleep
Symptoms
Usually gradual but may be abrupt. Often a
combination
Sensory more common than motor symptoms
C5-T1 most commonly
DERMATOMES
Neurology refresher…
Examination
Asymmetry to help decompression of nerve root
Reduced neck movements
Spurling’s test
Muscle weakness or sensory change
Change in tendon reflexes
Neural stretch tests
Acute torticollis
Acute whiplash
Chronic whiplash
Red flags
Yellow flags
Non-specific neck pain
Cervical radiculopathy
Back Pain
Prevalence
LBP affects 1/3 of UK population each year
Only 20% of people with LBP consult GP
MAINLY: non-specific and serious causes rare
Prognosis
Difficult to prognosticate because of irregular course
of symptoms
Risk factors for slower return to work:
leg pain as well as back pain
Repeated episodes
Co-morbidities
Manual work or lower socioeconomic class
Longer duration off work
Psychosocial factors
Definitions
Non-specific low back pain
Specific low back pain
Mechanical back pain
Inflammatory back pain
Non-Specific Low Back Pain
pain, tension, soreness, or stiffness in the lower
back which cannot be attributed to a specific
cause.
Sprains and strains included.
best thought of as a symptom or complaint —
not as a disease or homogeneous condition.
Non-specific low back pain is also called simple,
or uncomplicated, low back pain.
Inflammatory low back pain
low back pain and stiffness aggravated by rest
or sleep
often waking the person in the second half of
the night.
It lasts >30 minutes after getting up
relieved by physical activity & NSAID.
typical of ankylosing spondylitis and other
rheumatic conditions.
Mechanical LBP
varies with posture or movement.
E.G.: aggravated by standing and relieved by
sitting or lying; in others: vice versa.
Mechanical low back pain is typical of non-
specific low back pain, and specific causes such
as sciatica, vertebral fracture, and facet joint
injury.
Importance is exclusion of inflammatory back
pain.

Diagnosis
Rule out serious pathology
Cauda
Equina
Red flags for cauda equina
Saddle anaesthesia or paraesthesia
Recent onset bladder dysfunction
Recent onset faecal incontinence
Perianal sensory loss
Unexpected laxity anal sphincter
Severe OR progressive neuro deficit
Red flags for fracture
From medical history:
Sudden onset of severe central pain relieved by
lying down.
Major trauma e.g. RTA, fall from a height. Minor
trauma, or even just strenuous lifting, in people
with osteoporosis.
From physical examination:
Structural deformity of the spine (such as a step
from one vertebra to an adjacent vertebra)
Red flags for cancer or infection
older than 50 years, or younger than 20 years
History of cancer.
Recent bacterial infection (for example urinary
tract infection).
Intravenous drug misuse.
Immune suppression.
Red flags for cancer or infection
Constitutional symptoms, such as fever, chills, or
unexplained weight loss.
Pain that remains when lying down,
aching night-time pain that disturbs sleep,
thoracic pain (which could also be caused by
an aortic aneurysm).
O/E: Structural deformity of the spine (such as
scoliosis).
Ruled out serious pathology…
Check pain
From back
Is mechanical
Is not inflammatory (?ESR, CRP)
Check for long term prognosis
Misunderstanding of the cause of back pain.
The belief that pain and activity are harmful.
Sickness behaviours, such as extended rest.
Overprotective family.
Social withdrawal, lack of support.
Emotional problems such as low or negative mood, depression, anxiety,
or feeling under stress.
Problems with claims for compensation or applications for social
benefits.
Inappropriate expectations of treatment, such as low expectations of
active participation in treatment.
Management
positive attitude
realistic expectations.
Avoid ‘threatening’ language
'the normal ageing process of the spine' rather
than 'wear and tear', 'crumbling discs', or
'damage to disc or joint'.
Information:
real physical cause
disturbance of function, not by serious structural
damage.
Settles in most people but can recur repeatedly
Analgesia, mobilise and back to work ASAP
normal activities should be paced
The aim is to do a little more each day.
Information
Care with lifting and twisting
Cushion between knees when sleeping on side
No need for complete resolution before work
Work can help with distraction
Analgesia (paracet/NSAID/opioid)
?use of diazepam x 5/7
Expect resolution <6 weeks
Chronic (>6 weeks)
Structured exercise programme
Manual therapy
Acupuncture
Poor response?
Check for red flags
Check for yellow flags
Consider other conditions
Consider referral to pain mgt clinic
If severe, consider specialist spinal surgical
service -> ?fusion
Not recommended for chronic
low back pain
Non-specific
Less than a year
Should not be treated or referred with:
Not recommended for chronic low
back pain
Alexander technique (exercise likely to be more
cost-effective) not available on NHS
Massage
Percutaneous electrical nerve stimulation (PENS)
Transcutaneous electrical nerve stimulation
(TENS)
SSRI
Injection of substances into the back
Not recommended for chronic low
back pain
Laser therapy
Interferential therapy
Therapeutic ultrasound
Lumbar supports
Traction
Radiofrequency electrothermal therapy
Percutaneous intradiscal radiofrequency
thermocoagulation (PIRFT)
Neuroreflexive therapy
Opioids in Back pain
On the increase
Some estimates 30% of LBP last >1y
Cochrane review
Use of opioids
4 studies
3 compared tramadol to placebo
900 patients in total…
There still remains little evidence in the
medical literature to address the
concerns of physicians and patients
regarding the effect of opioids on pain
intensity, improved function and risk of
drug abuse.
