Association between pedicle screw dimensions and pedicle morphometry in computed tomography scans.
Article in Journal of Taibah University Medical Sciences, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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: Previous studies have investigated the morphometry of vertebrae and the general concept of pedicle breach. However, direct correlations have not been established between pedicle morphometry and screw dimensions. This study aimed to determine the relationship between the size and direction of pedicle screws and the morphometry of the pedicles of thoracolumbar vertebrae, which were assessed using computed tomography (CT) scans. Methods: This single-center, retrospective observational study included 60 adult patients admitted with thoracic and lumbar vertebral fractures who underwent posterior spinal stabilization between October 2018 and November 2023. Pre- and post-operative CT scans were analyzed to assess the pedicle and vertebral morphometry, screw dimensions, and breach grade. Paired tests and correlation analyses were performed. Results: In total, 177 vertebrae (354 pedicles) were analyzed in 60 patients. Most fractures were burst type (85%), mainly at T12-L1. Post-operative pedicle width ( Conclusions: CT morphometry analysis demonstrates that individual pedicle dimensions should guide screw selection. Narrow thoracic pedicles and screws that exceed 80% of the pedicle width heighten the risk of breach. Routine CT measurement enables accurate instrumentation and safer stabilization.
