Biomechanical comparison of two fixation constructs for displaced quadrilateral surface acetabular fractures: a finite elements analysis.
Article in BMC musculoskeletal disorders, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
backgroundAcetabular fractures involving the quadrilateral surface demonstrate increasing prevalence and pose substantial challenges in orthopedic management. While stable fixation is essential to prevent complications such as post-traumatic arthritis, the optimal surgical technique for complex fractures, particularly those affecting the quadrilateral surface, remains controversial. This finite element analysis evaluates the comparative biomechanical performance and clinical utility of acetabular quadrilateral surface plates (AQSP) versus conventional reconstruction plates in treating acetabular T-type fractures.
methodsThis study employed finite element analysis (FEA) to evaluate the biomechanical performance of two fixation methods: the conventional reconstruction plate and the AQSP. Three-dimensional models of T-type acetabular fractures were constructed and subjected to simulated physiological loading conditions, with stress distribution, displacement patterns, and implant stability assessed through quantification of von Mises stress, contact pressure, and displacement magnitudes.
resultsThe AQSP exhibited superior mechanical stability relative to the conventional reconstruction plate, demonstrating more uniform stress distribution and reduced displacement. Quantitative analysis revealed enhanced stability metrics for the AQSP, including lower von Mises stress (37.99 MPa) and diminished displacement (0.39 mm).
conclusionThe AQSP provides enhanced biomechanical stability for quadrilateral surface fracture fixation compared to conventional reconstruction plates. Its optimized stress distribution and reduced displacement establish the AQSP as a viable alternative for improving clinical outcomes in complex acetabular fractures.
