[Computed Tomography's Impact on the Surgical Planning for Posterior Malleolar Fractures].

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
Objective: The present study aimed to evaluate the influence of computed tomography (CT) on the preoperative planning of posterior malleolus (PM) fractures of the ankle, comparing its information with that of conventional radiographs and assessing its impact on surgical treatment. Methods: The study included 81 patients with PM fractures, whose radiological and CT images were analyzed by 33 specialized orthopedic surgeons. The study had two stages, with a radiological assessment on the first, and the second having radiological and CT evaluation. In both stages, we asked surgeons about the PM size, fracture stability, preoperative management, and potential modifications after CT analysis. Results: Considering only radiographs, 83.5% of the evaluators selected PM fixation. However, CT addition modified this choice in 49.1% of the cases, influencing the surgical access route and the type of osteosynthesis. In 34.7% of cases, CT revealed a larger PM fragment than radiographs, demonstrating that it is superior in evaluating fracture size and morphology. Conclusion: The surgical planning of ankle fractures with PM involvement should routinely include CT scans for a more precise fracture line assessment and a potential change in the therapeutic decision based on simple radiography alone.
