Fifty-eight patients with a clinical or radiographic diagnosis of cervical spinal cord injury underwent Pantopaque myelography on an emergency basis. Twenty-five per cent of these patients demonstrated evidence of spinal cord compression after reduction by spinal traction, as evidenced by the presence of a myelographic defect. Less than half of these patients had a defect that the authors thought required emergency surgical decompression. Two of the five patients so operated upon demonstrated an improvement in neurological function after operation that was much greater than that which would have been predicted before operation. The finding of these few patients who made a significant improvement after operation may justify the myelographic investigation of all patients with evidence of serious cervical spinal cord injury. Based on our experience, Pantopaque myelography may offer adequate, accurate, and useful information for the immediate management of spinal cord-injured patients.
