Can the Finite Element Method Be Applied to Patient-Specific Implant Evaluation?
Article in Clinics in orthopedic surgery, 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
Background: The introduction of 3-dimensional printing has revolutionized orthopedic surgery, enabling patient-customized implants to address complex bone defects. However, ensuring reliable fixation remains a considerable challenge. Herein, we developed a finite element analysis (FEA)-based flow designed to evaluate implant fixation across various anatomical sites. Methods: We applied this flow to the pelvic region to validate its fixation strategies and optimize the design across different osteointegration stages: acute, pre-, and post-osteointegration. Effects of screw-fixation methods (short screws in the cancellous bone and long screws in the cortical bone) on patient outcomes were analyzed and validated using data from 2 patients. Results: Predictive outcomes aligned closely with clinical results in terms of the location and timing of screw-fixation failure. Conclusions: The study findings affirm the potential of FEA to verify implant design and fixation strategies and to enhance surgical success rates through improved preoperative planning.
