Examiner's Questions

Please summarise the case

  • This is a 63 year old woman listed for posterior cervical fusion
  • She has multiple comorbidities of significance, including rheumatoid arthritis, hypertension and obstructive sleep apnoea, the severity of which is unknown
  • She has a long smoking history and possible undiagnosed COPD
  • She likely has a difficult airway with limited neck mobility and instability of the cervical spine
  • She will need to be proned for the procedure

What further investigations are required?

  • Previous anaesthetic history
  • A thorough cardiovascular and respiratory history and examination to assess for ischaemic heart disease and obstructive lung disease
  • Formal assessment of her obstructive sleep apnoea to assess severity
  • Neurological examination to establish her current symptoms and neurological deficits

What features might you expect to see on lateral cervical spine xray?

  • Disruption of vertebral canal lines, either anterior or posterior, or both
  • Anterior subluxation of the atlas, demonstrated by increased distance between odontoid process of the axis and arch of the atlas
  • Intervertebral disc space reduction
