Acute back pain

Joy.

Red flags

Beware cognitive bias...

  • cauda equina syndrome:
    • bilateral sciatic/radicular pain
    • bladder/bowel symptoms
    • See page for full list of symptoms
  • Traumatic spinal fractures
    • major trauma
    • point tenderness over single vertebral body
    • sudden onset severe central spinal pain relieved by lying down
  • Non-traumatic spinal fractures
    • classically fragility fractures - compression fractures
    • consider bone metastases, multiple myeloma
  • Bony metastases
    • age >50
    • Severe persistent lumbar pain;
    • thoracic back pain;
    • night spinal pain preventing sleep
    • spinal pain aggravated by straining/coughing/sneezing/defaecation
    • localised spinal tenderness
    • MRI preferred
  • infection - Discitis, epidural abscess
    • risk factors: DM, IVDU, previous HIV infection

Discharge advice

  • Continue daily activities as soon as possible
  • But off work until can walk/perform emergency stop → then discuss with work re adjusted duties (heavy lifting, etc.)
  • Multimodal analgesia
    • "the goal is to be able to walk to the toilet and back"...
  • Adaptations
  • Most back pain resolves within 6-8 weeks

Advice re imaging for patients

  • NICE NG59 1.1.4: Do not routinely offer imaging in a non-specialist setting for people with low back pain with or without sciatica. [2016]
  • Early imaging associated with higher intervention rates, worse outcomes
  • Role is more for planning interventions e.g. surgery
  • MRI findings are common in asymptomatic people
