Posttraumatic Syringomyelia

Ten cases of posttraumatic syringomyelia are reported. The common manifestations were pain, numbness, muscle weakness and dissociated sensory loss of involved extremities. The occurrence of syringomyelia are related to hemorrhage, cystic degeneration and arachnoid adhesion at the site of spinal injury. The interval from spinal injury to onset of the symptoms of syringomyelia range from 5 months to 20 years. The principle of treatment is to remove the causes of forming syringomyelia, to recover free communication of the cerebrospinal fluid pathways and to shunt the syrinx. Follow up examinations were carried out in all cases and got favorable results.
