Accuracy of 3D-navigated screw fixation in pelvic ring fractures: a single-centre consecutive observational case series.
Observational study in European journal of orthopaedic surgery & traumatology : orthopedie traumatologie, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
purposeConventional 2D fluoroscopy-based screw fixation of pelvic ring fractures has high screw misplacement rates and can be technically challenging. Implementation of 3D image guidance is presumed to simplify screw placement and improve procedural safety. The objective of this study was to evaluate the accuracy of 3D navigation in percutaneous screw fixation of pelvic ring fractures.
methodsA consecutive case series including all patients undergoing 3D-guided screw fixation of pelvic ring fractures between 2019 and 2022 was conducted. Primary study endpoints were screw misplacement, neurological complications, and surgical site infections. Data were analysed using descriptive statistics.
resultsA total of 90 consecutive patients (180 screws) were included, with 120 transsacral-transiliac screws (TSTI) and 60 sacral-iliac (SI) screws used for posterior fixation, 5 retrograde transpubic screws placed for anterior fixation, and 23 antegrade screws placed into the superior rami. For two patients (2.7%), screw misplacements were observed. No neurological complications occurred due to screw misplacement.
conclusionsThe result of the current study shows that 3D navigation provides excellent screw placement accuracy, with minimal screw misplacements and no neurological complications due to screw misplacement.
