title: [Minimally invasive surgical treatment for lumbar degenerative disease with IsoC-3D navigation under Mast Quadrant system].
abstract: OBJECTIVE
  To evaluate the effects of surgical treatment of IsoC-3D navigation assisted percutaneous pedicle screw fixation,vertebral canal decompression and interbody fusion using Mast Quadrant system in patients with lumbar degenerative disease.
  
  
  METHODS
  From January 2009 to February 2010,21 patients with lumbar degenerative disease were treated with IsoC-3D navigation under Mast Quadrant system. There were 12 males and 9 females, with an average age of 50.2 years (ranged,36 to 72 years). All patients underwent discectomy,vertebral canal decompression, cage implantation using Mast Quadrant system and IsoC-3D navigation assisted sextant lumbar fixation. Clinical outcomes were evaluated with Oswestry disability index (ODI), Visual analog scale (VAS) and degree of satisfaction of patients.
  
  
  RESULTS
  Eighteen patients (85.7%) were followed up from 6 to 18 months with an average of 10 months. No surgery-related complications were found. The preoperative, postoperative ODI scores was 49.6 +/- 12.2 and 17.2 +/- 9.2, respectively (P < 0.01); VAS score of leg pain decreased from preoperative 75.2 +/- 10.0 to 12.2 +/- 11.8 at final follow-up (P < 0.01); VAS score of lumbago decreased from preoperative 59.9 +/- 17.3 to 16.6 +/- 11.5 at final follow-up (P < 0.01). Sixteen patients obtained satisfactory results.
  
  
  CONCLUSIONS
  IsoC-3D navigation assisted percutaneous pedicle screw fixation,vertebral canal decompression and interbody fusion using Mast Quadrant system could achieve satisfactory clinical results in treating lumbar degenerative disease and may be a better alternative to conventional surgical procedures. It has advantages such as limited tissue damage, less blood loss, short time in hospital.
