Myelography for severe thoracolumbar injuries.

Myelography was carried out on 30 patients with severe thoracolumbar injuries. In ten cases the myelography gave specific information which could not have been obtained by any other method. Myelography made within 1 month of trauma gave specific information in only one of 16 cases. Late myelography, in nine of 14 cases, provided valuable specific information about the type of cord atrophy, dorsal scar formation and transsection of the cord.
