Key takeaways:
- Robot-guided fusion was linked with less radiation exposure vs. fluoroscopy-guided fusion.
- Robot-guided fusion was linked with lower dose estimates and intraoperative bleeding vs. fluoroscopy-guided fusion.
SAN FRANCISCO — Robot-guided spinal fusion may improve clinical outcomes compared with fluoroscopy-guided spinal fusion, according to results presented here.
“Overall, our meta-analysis of randomized controlled trials associates robot-guided spinal fusion with decreased radiation exposure and corresponding dose estimates, decreased intraoperative bleeding, increased surgical duration, improved accuracy in the sensitivity analysis when compared to the fluoroscopy-guided spinal fusion,” Jordan J. Levett, BS, said in his presentation at the American Academy of Orthopaedic Surgeons Annual Meeting.
Levett and colleagues performed a meta-analysis of eight randomized controlled trials that compared robot-guided and fluoroscopy-guided spinal fusion in adults.
Outcomes measured included radiation exposure, dose estimates, pedicle screw accuracy, intraoperative bleeding, surgical duration and hospital length of stay.
Levett said robot-guided spinal fusion was associated with an average decrease in radiation exposure of 26 seconds compared with fluoroscopy-guided fusion. He said robot-guided fusion was associated with a 40.2% decrease in cancer and detrimental hereditary disorder risks compared with fluoroscopy-guided fusion.
In addition, he noted that robot-guided fusion was associated with a decrease in intraoperative bleeding and an increase in surgical duration compared with fluoroscopy-guided fusion.
There were no significant differences between the two groups in pedicle screw accuracy or postoperative length of hospital stay, according to Levett.
“Larger, multicenter, randomized controlled trials using dose meters on both patients and surgeons are warranted to validate these results and to provide more precise estimates of radiation exposure while evaluating its long-term patient-reported outcome measures,” Levett said.
