Your patient, James Cook, a 32 year old travel writer came off his motorcycle which skidded on some ice. The paramedics have him immobilised on a spinal board with a rigid cervical collar in place. According to them there was no loss of consciousness at any time, and he is responding appropriately to commands. He is not complaining of any neck pain.

On general examination you find no neurology and no evidence of other injury. With an assistant manually stabilising his neck, you remove the collar and examine the patient. There is no bony tenderness, deformity or defect.

Think you can handle this one, or do you want to go back to the manic kazoo-wielding burger juggler?
