Screw loosening

Results indicated that robot-assisted pedicle screw placement in TLIF had a lower screw loosening rate and similar patient-reported outcomes compared with the fluoroscopy-guided technique 1)

Loosening of spine arthrodesis could be successfully treated by percutaneous injection of bone cement under CT and fluoroscopy guidance 2).
