Mixed Reality for Localisation of Rib Fractures Before Surgical Stabilization: A Pilot Study of an Innovative Tool.
Article in Surgical innovation, 2026. 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
BackgroundAccurate localisation of rib fractures is crucial for successful surgical stabilisation of rib fractures (SSRF). Mixed reality (MR) technology can overlay anatomical imaging onto a patient in real-time, which may facilitate the visualisation of rib fractures, allowing accurate skin surface markings for incision. This pilot study assessed the feasibility of using mixed reality (MR) for rib fracture localisation in SSRF.MethodsThis study involved a pre-clinical phase with two healthy patients and a clinical phase with six patients undergoing SSRF in a single tertiary trauma centre. CT scans were transformed into patient-specific 3D holographic models, which were projected through Microsoft HoloLens2TM (HL2) onto the patient after anatomical calibration. The study assessed hologram projection, number of fractures identified, time taken, and distance from skin marking to the fracture site. Iterative improvements to the MR system were implemented throughout the study.ResultsStable and accurate hologram projection was achieved in both phases. In the clinical portion, MR identified 54 rib fractures, including subscapular fractures, compared to 30 identified by US. The mean time to mark all fractures was 9.07 minutes for MR and 10.02 minutes for US. The mean displacement from skin marking to the fracture site was 2.89 cm for MR and 2.04 cm for US. Technical challenges included distorted surface anatomy and positional variations.ConclusionMR technology in the setting of SSRF is feasible and facilitates de-novo visualisation of rib fractures. Technical limitations must be addressed before widespread clinical use.
