[Prognostic factors related to gunshot wounds to the spine in patients submitted to laminectomy].

The spinal trauma related to civilian gunshot missile still remains a serious neurological event that carries a dismal prognosis almost in all cases. Its surgical indication also is a matter of discussion. Our goal is to identify the aspects that could influence the prognosis after surgery to this kind of lesions. We conducted a retrospective study of 45 consecutive patients submitted to laminectomy at Hospital de Base do Distrito Federal (Brasília, Brazil), testing the following aspects: initial neurological status, level of the deficit, surgical timing, use of methilprednisolone and presence of dural tearing. Among those, the initial clinical presentation and the level of the lesion (60% of the patients with cauda equina syndrome and 53% of that with lesions in the lombar region improved their neurological status after laminectomy) were the most important factors affecting the outcome. Seventy percent of the patients experienced a pain relief after the surgical procedure.
