3 Epidemiology Very common disorder Affecting around one-third of the UK adult population each year [NICE guidelines]. Eighty percent of the population had back pain once or twice in their life [Urquhart el al 2008]. Around 20% of people with low back pain (that is, 1 in 15 of the population) will consult their GP about it [NICE guidelines].

4 Epidemiology The review of the health of Britain's working-age population by Dame Carol Black estimated that the annual costs of sickness absence and worklessness associated with working-age ill health were over 100 billion.

5 Epidemiology It is estimated that 4.5 million working days are lost each year due to back pain alone. Cost > 14 billions

6 Early referral is it good? RCT study in Norway Workers, aged between 18 and 60 On long-term sick leave with lower back pain Receive consultations with a physician (specialising in physical medicine and rehabilitation) and a physiotherapist improve skills to cope with their condition

7 Early referral is it good? Help return to work up to a year after they start sick leave than comparable people who were treated in primary care Conclusion: may be effective. [Nice guidelines]

16 Mr M S (cont..) Blood reuslts IgG g/l (6.00) IgA 5.77 g/l ( ) IgM 0.78 g/l ( )

17 Mr M S (cont..) Blood results FBC Total WBC (4-11) HB 11.7 ( ) Platelets 438 ( ) RBC 4.21 ( ) Haematochrit 0.37 l/l (0.51) Neutrophil ( ) C-reactive protein 12mg (0-5) What do you think?

18 Mr M S (cont..) MRI Discitis/osteiomyelitis A- Sagital T1-wieight images of the lumbar spine demonstrate T1 hypointense signal B- post gadolinium sagital fat suppressed T 1- weighted images showed marrow and disc enhancement with endplate erosion.

19 Mr M S (cont..) How would you treat it? Treated with Antibiotics Surgical fixation

20 Mr M S (cont..) OUTCOME 6 month later Post fixation L3/4 Much improved Medications Cocodamol 30/500 8 per day Pregabalin 150mg bd

21 Mr M S (cont..) What is your plan? Decrease Pregabalin and stop in 6 month Physio / ocupational therapy Psychotherapy discharge

22 Best imaging for osteomylitis?? Plain film X-ray Strengths: sensitive when infection well established, cheap and available Weaknesses: signs do not develop until days after infection

23 Best imaging for osteomylitis?? CT scan Strengths: more sensitive than plain X-ray film for detecting bone and disc erosions Weaknesses: less sensitive than MRI to soft tissue and abscesses + iodinated contrast administered

24 Best imaging for osteomylitis?? MRI Strengths: most sensitive for early detection (oedema) No radiation exposure Weaknesses: contraindications to MRI Calcium bone scan Strengths: useful if CT scan and MRI are equivocal Weaknesses: low spatial resolution require 2 days

25 Lessons to learn Early aggressive management is recommended if pain continue after 4 weeks following optimum initial treatment Re-assurance of the patient

26 Conclusion Multidisciplinary management following algorithms Long term management may include involving clinical psychologist for a coping strategy Sociopsychological approach
