[Radiation exposure to spine surgeon: a comparison of computer-assisted navigation and conventional technique].

To analyze the radiation exposure of surgeon in spine surgery and compare computer-assisted navigation and conventinal technique. While performing spine surgery, the surgeon is exposed to a significant amount of radiation. Spinal surgeons should be considered as workers of radiational occupation accordingly. Methods of reducing radiation exposure should be strongly recommended. Comparing with conventional fluoroscopic technique,the computer-assisted navigtion can reduce surgical time, radiation exposure, and has become an increasingly accepted and practiced from of intraoperative spinal navigation.
