Breakdown of Back pain Group 1 >85% non specific. Group 2 Spinal stenosis 3%, radiculopathy 4% Cauda equina syndrome 0.04% Group 3 Compression fracture 4% Cancer 0.7%, spinal infection 0.01% Ankylosing spondylitis 0.3-5% Other

Radiculopathy Typical sciatica history Location Motor assessment Straight leg raise, crossed SLR

Spinal Stenosis Pseudoclaudication Radiating leg pain Downhill treadmill Pain relieved by sitting Age >65

Cauda equina syndrome Rapidly progressive, severe neurological deficit Motor deficits >1 level Faecal incontinence Bladder dysfunction

Malignancy risk factors History of cancer* Unexplained weight loss Failure to improve after 1 month >50 year old

Vertebral infection Fever IV drug use Recent infection Specific Risk factors

Fracture Age Young: traumatic Older: osteoporotic Steroid use

Ankylosing spondylitis Young, male Morning stiffness Improvement with exercise Alternating buttock pain Wakening with pain in the second part of the night

Psychosocial factors Depression Passive coping strategies Job dissatisfaction High disability levels Disputed compensation Somatisation Catastrophising

Group 1 No routine imaging or tests required. Assess psychosocial overlay
