Abstract:
OBJECTIVES: We have analyzed relationship between pedicle screw loosening and bone mineral densitiy (BMD) after spinal arthrodesis with pedicle screw. MATERIALS AND METHODS: We have chosen 31 cases that had screw loosening radiologically on the follow up X-ray among the patients who underwent spinal arthrodesis with pedicle screws, and compared Saville's index that was measured by lateral view of preoperative X-ray with Dual energy X-ray absortiometry (DEXA) score.
