Comparative analysis of the pedicle screw accuracy, screw revision and loosening rate and radiation exposure of robotic-guided (RG), intraoperative computed tomography (iCT)-navigation guided, and fluoroscopy guided placement technique.

ABSTRACT:

Objective

This retrospective single-center study aimed to compare the accuracy and revision rates of pedicle screw (PS) placement using robot-guided (RG), intraoperative CT-navigated (iCT-nav), and fluoroscopy-guided (FG) techniques. Additionally, screw loosening and overall revision rates were assessed across all three methods.

Methods

Data from 237 consecutive patients who underwent PS placement using iCT-nav, FG, or RG were analyzed. Each PS was evaluated in intraoperative or postoperative CT and classified using the Gertzbein-Robbins Scale (GRS). Follow-up CT to assess fusion and screw loosening was performed at a median of 8 months (IQR = 5-17).

Results

A total of 1352 PS were placed: 444 with RG, 667 with FG, and 241 with iCT-nav. RG showed the highest rate of G
