Dr Darren Lillis A Pain in the Neck, on Ice with a Twist...
The Case • Mr HS • 52 yrs old • Shopkeeper • Normally fit and well • GP referral with neck and upper back pain
HxPC • Fell on the ice 4 weeks previously • Stepping down off a foot bridge, his two feet went out from under him • Landed on his sacrum • Felt a “shudder” transmitted from his sacrum to his neck on impact
HxPC continued • No loss of power or sensation in limbs • Got himself off the ground, walked home. • Went to work over the following 2 weeks • Ongoing lower cervical and upper thoracic pain Went to his GP Emergency Dept
PMHx etc • Appendectomy as child • No other relevant history • No medications or allergies • Lives with wife, non smoker, no alcohol • Full time employment
On examination • Kyphotic posture • Fixed flexion deformity in his C spine • Chin- chest distance= 5cm • Unable to flex his neck laterally • Only able to rotate approx 10 degrees R+L • Stated this was normal for him- no recent change associated with the fall
Examination condt • Tender over the lower cervical and upper thoracic regions- bone and muscular tenderness • Neuro examination was entirely normal
ED Management • Soft tissue injury • Analgesia • Physio • Discharge • Call from radiology- C spine fracture
Correct Diagnosis • C Spine fracture- C 6/7 fracture • X rays and posture in keeping undiagnosed Ankylosing Spondylitis
Admitted under Orthopedics • Further investigation
Treatment • No Miami J Cervical collar • No spinal precautions • Transferred to the Mater Spinal Unit once a bed became available • Reviewed by Rheumatology- Likely Ank Spond but inflammatory markers normal... burnt out
AnkylosingSpondylitis and C Spine fractures • Inflammatory arthropathy • Ligaments and discs become calicified- characteristic flexed posture, loss of flexibility • Incidence of spinal fractures is 4 times that of the normal population (1) • 75% of these occur in the lower C Spine region (2) • Multi level fractures associated with minor trauma (3)
