Summary
Robotic-assisted spinal screw placement is more accurate and efficient than navigation-assisted placement. Combining robots and navigation systems does not increase fluoroscopic views, offering a superior approach for spinal surgery.
Area of Science:
- Spinal surgery
- Medical robotics
- Surgical navigation
Background:
- Robotic and navigation systems offer improved accuracy for spinal screw placement compared to freehand techniques.
- Limited comparative studies exist on the accuracy and efficiency of robotic versus navigation-assisted spinal surgery.
Purpose of the Study:
- To compare the accuracy and efficiency of robotic-assisted versus navigation-assisted screw placement in spinal vertebrae.
Main Methods:
- Twenty-four spine models were divided into robotic and navigation groups.
- Accuracy was assessed using angular deviation and the Gertzbein and Robbins scale across spinal segments (C1-S1).
- Operation times were compared between the two techniques.
Main Results:
- Robot-assisted placement showed significantly less angular deviation (p < 0.001) across all segments.
- Robot-assisted placement had a higher rate of acceptable screws in upper spinal segments (C1-T4).
- Robot-assisted placement required significantly less operative time (p < 0.05).
Conclusions:
- Robotic assistance provides superior accuracy and efficiency for spinal screw placement compared to navigation.
- Robotic and navigation systems can be integrated without increasing fluoroscopic imaging requirements.
