This paper presents results of a prospective study for patients undergoing surgery for posttraumatic syringomyelia between 1991 and 2010. ⋯ The technique of decompression with arachnolysis, untethering, and duraplasty at the level of the underlying trauma provides good long-term results for patients with progressive neurological symptoms following ASIA A, B and E injuries. Treatment of patients with posttraumatic syringomyelia after spinal cord injuries with preserved motor functions (ASIA C and D) remains a major challenge. Future studies will have to establish whether thecoperitoneal shunts would be a superior alternative for this subgroup.

The Food and Drug Administration has not cleared the following medical devices for the use described in this study. The following medical devices are being discussed for an off-label use: cervical lateral mass screws. ⋯ The screw-claw-rod technique restricts motion much like the standard Harms technique, making it an acceptable alternative technique when aberrant arterial anatomy precludes the placement of C-2 pars/pedicle screws or C1-2 transarticular screws.

The purpose of this paper was to systematically review and critically appraise the evidence for whether there are differences in outcomes or recovery after thoracic spinal cord injuries (SCIs) based on the spinal level, the timing of intervention, or cause of SCI. ⋯ The overall strength of evidence for all outcomes reported is low. Definitive conclusions should not be drawn regarding the prognosis for outcome and recovery after thoracic SCI. From a physiological standpoint, additional methodologically rigorous studies that take into consideration various levels of injury in more anatomically and physiologically relevant form are needed. Use of validated, comprehensive outcomes tools are important to improve our understanding of the impact of thoracic SCI and aid in examining factors in recovery from thoracic SCI.
