Acute ascending myelopathy of the spine.
Ascending myelopathy of the cervical spine is a clinical condition in which ascending paralysis manifests itself from 24 hours to 4 weeks after the initial injury. One hundred thirty-four patients with spinal cord injury were reviewed; 80 underwent surgery and 54 were treated conservatively. Ten of the 54 patients who did not have surgery ascended one to four levels, whereas only 4 of the 80 patients who underwent surgery ascended to similar levels. Myelography demonstrated diffuse swelling of the cord that extended approximately two segments above and below the injured vertebrae. Magnetic resonance imaging showed intrathecal hemorrhage within the first 2 weeks followed by cord atrophy within 4 weeks after the initial trauma. Thorough decompression of the cord with rigid internal fixation markedly reduced the incidence of this complication.
