Summary

Definition

History and exam

Key diagnostic factors

  • presence of risk factors
  • age group 16 to 30 years (trauma)
  • age group 30 to 50 years (disc disease)
  • age group 40 to 75 years (malignancy)
  • acute onset and duration of symptoms
  • chronic onset and duration of symptoms
  • back pain
  • numbness or paraesthesias
  • weakness or paralysis
  • bladder or bowel dysfunction
  • hyper-reflexia
  • sensory loss
  • muscle weakness or wasting
  • loss of tone below level of suspected injury (spinal shock)
  • hypotension and bradycardia (neurogenic shock)
  • complete cord transection syndrome
  • cauda equina syndrome
  • central cord syndrome
More key diagnostic factors

Other diagnostic factors

  • history of malignancy
  • immunosuppression
  • intravenous drug use
  • loss of rectal sphincter reflex
  • loss of appendicular reflexes
  • local deformity of spine on palpation
  • Brown-Sequard's syndrome
  • anterior cord syndrome
  • posterior cord syndrome
Other diagnostic factors

Risk factors

  • age between 16 and 30 years and male sex
  • trauma
  • tumour
  • osteoporosis
  • high-risk occupation
  • high-risk recreational activities
  • intravenous drug use
  • immunosuppression
More risk factors

Diagnostic investigations

1st investigations to order

  • MRI spine
  • gadolinium-enhanced MRI spine
  • plain spine x-ray
  • CT spine
  • CT myelography
More 1st investigations to order

Investigations to consider

  • full blood count with differential
  • erythrocyte sedimentation rate and C-reactive protein
  • blood or cerebrospinal fluid cultures
  • tumour biopsy and histopathology
  • urodynamic studies
  • positive emission tomography (PET) scan of the spine
More investigations to consider
