Impact of Navigation Assistance on Perioperative Outcomes in Sacroiliac Joint Arthrodesis: A Comparative Study.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background Navigation systems are increasingly applied to enhance precision and reduce radiation exposure in sacroiliac joint (SIJ) arthrodesis. However, evidence comparing navigated and conventional procedures remains limited. This study evaluated perioperative outcomes of navigation-assisted versus non-navigated SIJ arthrodesis using the DIANA implant system (Signus GmbH, Alzenau, Germany). Methods A retrospective comparative study was conducted on 30 patients who underwent SIJ arthrodesis between 2011 and 2021 at the Department of Neurosurgery, Hospital of the Order of Merciful Brothers, Regensburg, Germany. Thirteen patients received navigation-assisted surgery and 17 underwent conventional fluoroscopy-guided procedures. Perioperative parameters assessed included operative time, radiation dose, fluoroscopy time, and intraoperative blood loss. Group comparisons were performed using independent-samples t-tests and one-way ANOVA, with significance set at p < 0.05. Results Baseline characteristics (age, sex, BMI) were comparable between groups. Mean operative time was slightly shorter with navigation (146 ± 37 min) versus non-navigated procedures (162 ± 31 min; p = 0.198). Radiation dose was lower in the navigation group (718 ± 379 mGy·cm² vs 1015 ± 532 mGy·cm²; p = 0.100), though not statistically significant. Fluoroscopy time was significantly reduced with navigation (82 ± 40 s vs 112 ± 34 s; p = 0.037). Blood loss was similar between groups (246 ± 125 mL vs 238 ± 110 mL; p = 0.855). Conclusion Navigation in SIJ arthrodesis significantly decreases fluoroscopy time while maintaining similar operative duration, radiation dose, and blood loss compared to conventional techniques. Its main advantage lies in improving imaging efficiency and workflow precision. Larger prospective studies are warranted to validate these findings and assess long-term clinical outcomes.
