title: [Intraoperative three-dimensional imaging to monitor selective decompression in lumbar spinal stenosis].
abstract: BACKGROUND
  We are looking for a possibility to examine the amount of decompression in operations for spinal stenosis with an Iso-C(3D) fluoroscope (Siemens).
  
  
  METHODS
  In ten patients operated on because of spinal stenosis from one side with undercutting, we performed a scan with the Iso-C(3D) fluoroscope during the operation. In five patients we additionally performed intraoperative myelography.
  
  
  RESULTS
  In all cases we were able to make useful scans. Two times we changed our surgical procedure because of the scans. There were no complications because of the investigation with the Iso-C(3D) fluoroscope and none related to the myelography, but the myelography was dispensable.
  
  
  CONCLUSIONS
  It is possible and useful to investigate the decompression in spinal stenosis intraoperatively with less effort.
