The effect of 3D virtual surgical planning in sacroiliac joint fusion.
Article in Brain & spine, 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: Sacroiliac (SI) dysfunction causes of up to 30 % of lower back pain. When conservative treatment is insufficient, SI joint fusion (SIJF) can be indicated to reduce pain. Due to high anatomical variability, poor visibility during intraoperative 2D fluoroscopic imaging, and the absence of 3D spatial information, placing the implant in a stable configuration without damaging critical structures is challenging. To improve patient outcomes, a virtual surgical planning (VSP) method using simulated fluoroscopic images has been developed. Research question: What is the effect of VSP on patient outcomes, including complications, pain scores, satisfaction scores, and Oswestry Disability Index (ODI) scores? Methods: This retrospective case-control study compared procedures performed with VSP to those conducted prior to its implementation. Data were collected from the medical records, Numeric Rating Scale (NRS) questions, and patient reported outcome measures (PROMs). All postoperative CT scans were assessed on implant placement (mal)positioning and fractures. Malposition complications were categorized as severe malposition and suboptimal implant placement. Results: Seventy-eight procedures were included, 43 in the VSP group and 35 in the conventional group. Severe malposition complications reduced from 9 % to 0 % after VSP was implemented. Suboptimal implant placement reduced from 46 % to 9 % of the interventions. Sacral fractures reduced from 37 % to 14 %. All other primary outcome measures did not show a significant difference between the groups. Conclusions: VSP in SIJF reduced implant malpositioning and sacral fractures. This can lead to better patient outcomes. A larger multicenter study is needed to explore the broader impact of VSP on SIJF.
