Fracture morphology and multidirectional instability in failed closed reduction of pediatric supracondylar humerus 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
Purpose: To evaluate clinical and fracture-related factors associated with failed closed reduction in high-risk pediatric supracondylar humerus fractures (SCHF), with emphasis on fracture morphology and intraoperative multidirectional instability. Methods: This retrospective cohort study included 318 consecutive children aged 2-12 years who underwent surgery for Gartland type III SCHF or intraoperatively confirmed Gartland type IV instability between 2015 and 2025. Fractures were classified as typical extension-type, medial oblique, lateral oblique, or flexion-type. Univariable and multivariable logistic regression analyses were performed. Results: Closed reduction was successful in 192 patients, whereas 126 required conversion to open reduction. Flexion-type fractures had the highest open reduction rate (80.0%; Conclusions: Flexion-type morphology and intraoperatively confirmed Gartland type IV instability were strongly associated with failed closed reduction. These findings may help surgeons anticipate reduction difficulty and plan operative resources in high-risk pediatric SCHF. Significance of Study: Recognizing fracture morphology and intraoperative multidirectional instability may help surgeons anticipate failed closed reduction in high-risk pediatric SCHF. Level of evidence: III.
