Key Points
- Red flags indicate potentially serious pathology such as fracture, malignancy, infection, or cervical cord compression and necessitate immediate investigation and/or specialist referral
- Key red flags from history: significant trauma, history of cancer, constitutional symptoms (fever, weight loss), IV drug use, immunosuppression, steroid use, age >55 at first onset, severe unremitting night pain
- Key red flags from examination: upper motor neuron signs (hyperreflexia, clonus, positive Hoffmann's/Babinski), gait disturbance, bowel/bladder dysfunction, progressive neurological deficit
- Also consider cervical arterial dissection (CAD) in younger patients (<55) with acute onset of unfamiliar severe headache or neck pain, especially after minor trauma
- Vascular red flags (5Ds and 3Ns): dizziness, diplopia, dysarthria, dysphagia, drop attacks, nystagmus, nausea, numbness (perioral)
Red Flags by Category
Serious Spinal Pathology (Fracture, Malignancy, Infection)
| Red Flag | Condition to Consider |
|---|---|
| Significant trauma (e.g. fall in osteoporotic patient, MVA) | Bony/ligamentous disruption |
| History of cancer | Metastatic disease |
| Constitutional symptoms: fever, weight loss, anorexia | Malignancy, polymyalgia rheumatica, giant cell arteritis |
| Fever, meningism, immunosuppression, IV drug use | Infection: epidural abscess, discitis, SAH |
| Prolonged corticosteroid use | Pathological fracture, infection |
| Age >55 at first onset | Higher probability of serious pathology |
| Severe unremitting night pain | Malignancy, infection |
| History of rheumatoid arthritis | Atlanto-axial instability |
Neurological (Cervical Myelopathy / Cord Compression)
Signs and symptoms of upper motor neuron pathology require urgent assessment:
- Gait disturbance / coordination difficulties
- Bladder and/or bowel dysfunction
- Upper and/or lower limb motor or sensory disturbance
- Hyperreflexia, clonus, positive Hoffmann's or Babinski signs
- Clumsy hands / dropping items
All patients with signs of acute spinal cord compression should be referred urgently for orthopaedic or neurosurgical assessment.
Vascular (Cervical Arterial Dissection / VBI)
Consider cervical arterial dissection in:
- Younger patients (<55 years)
- Acute, sudden onset of unfamiliar headache or neck pain
- Moderate to severe, often progressive pain
- Spontaneous onset or following minor trauma/neck strain
- Recent unfamiliar neurological symptoms
Screen for the 5Ds and 3Ns of vertebrobasilar insufficiency:
- Dizziness/unsteadiness, diplopia, dysarthria, dysphagia, drop attacks
- Nystagmus, nausea/vomiting, numbness (perioral)
Concurrent Cardiopulmonary
Concurrent chest pain, shortness of breath, or diaphoresis with neck pain warrants consideration of cardiac or thoracic pathology.
Recommended Actions When Red Flags Present
- Acute cord compression: urgent referral to hospital for orthopaedic/neurosurgical assessment
- Other red flags: investigate appropriately (FBC, ESR as baseline; further imaging as indicated) and refer to a specialist if warranted by findings
- Routine imaging in acute neck pain without red flags does not provide clinical benefit
