This month’s Image Quiz from the JBJS Journal of Orthopaedics for Physician Assistants (JOPA) presents the case of a 55-year-old woman with neck pain and upper-extremity weakness after a motor vehicle accident that occurred 1 week prior, during which she sustained a whiplash injury. She notes severe bilateral arm weakness, “clumsy hands,” and mild lower-extremity weakness with walking. The bilateral upper-extremity muscle groups have a strength of 3 of 5, and the lower-extremity muscle groups have a strength of 5 of 5. Sensation remains intact throughout the upper and lower extremities.
Select from among four choices as the most likely diagnosis:
- Central cord syndrome
- Brown-Séquard syndrome
- Anterior cord syndrome
- Posterior cord syndrome
