title: The bullet in the dural sac. How to catch it? A report of two cases.
abstract: OBJECTIVE
  The purpose of this article is to present two cases of penetrating gunshot injuries to the lumbar spine with migration of the bullets within the dural sac and to describe the method of removal of the bullet from the dural sac.
  
  
  METHODS
  Two cases of penetrating gunshot injuries to the lumbar spine with migration of the bullets within the dural sac are presented. Clinical course, diagnostic tools, and management of two patients who suffered from these injuries are illustrated. The method of removal of the bullet from the dural sac is described too.
  
  
  RESULTS
  The wounds in these two cases healed without infection. The neurological status of our patients improved gradually. Radiographs taken 2 years after the injury did not demonstrate the postoperative instability of the lumbar spine.
  
  
  CONCLUSIONS
  The bullet in the dural sac at the level of the cauda equina must be removed. The method proposed by us can facilitate this procedure.
