Immediate mini-myelography in acute cervical cord injuries.

The use of contrast myelography in the evaluation of acute cervical spinal cord trauma is controversial. The purpose of employing such a technique is to demonstrate any persistent extradural cord compression after the spine is realigned by skeletal traction. The surgical correction of such compression may result in enhanced neurological recovery. The "mini-myelogram" is accomplished by performing a lateral C1/C2 spinal puncture and injecting a low volume of Pantopaque into the subarachnoid space. Demonstration of significant extradural compression results in emergency surgery for appropriate decompression. A small percentage of patients may enjoy enhanced recovery due to the decompression. A description of the technique and results of 90 patients undergoing mini-myelography are presented.
