ABSTRACT
PURPOSE:
Multiple solutions for navigation-guided pedicle screw placement are available. However, the efficiency with regard to clinical and resource implications has not yet been analyzed. The present study's aim was to analyze whether an operating room sliding gantry CT (ORCT)-based approach for spinal instrumentation is more efficient than a mobile cone-beam CT (CBCT)-based approach.METHODS:
This cohort study included a random sample of 853 patients who underwent spinal instrumentation using ORCT-based or CBCT-based pedicle screw placement due to tumor, degenerative, trauma, infection, or deformity disorders between November 2015 and January 2020.RESULTS:
More screws had to be revised intraoperatively in the CBCT group due to insufficient placement (ORCT 98, 2.8% vs. CBCT 128, 4.0%; p = 0.0081). The mean time of patients inside the OR (Interval 5 Entry-Exit) was significantly shorter for the ORCT group (ORCT mean, [95% CI] 256.0, [247.8, 264.3] min, CBCT 283.0, [274.4, 291.5] min; p < 0.0001) based on shorter times for Interval 2 Positioning-Incision (ORCT 18.8, [18.1, 19.9] min, CBCT 33.6, [32.2, 35.5] min; p < 0.0001) and Interval 4 Suture-Exit (ORCT 24.3, [23.6, 26.1] min, CBCT 29.3, [27.5, 30.7] min; p < 0.0001).CONCLUSIONS:
The choice of imaging technology for navigated pedicle screw placement has significant impact on standard spine procedures even in a high-volume spine center with daily routine in such devices. Particularly with regard to the duration of surgeries, the shorter time needed for preparation and de-positioning in the ORCT group made the main difference, while the accuracy was even higher for the ORCT.Palavras-chave
