Risk factors for ultrasound-guided closed reduction failure of unstable humeral lateral condylar fractures in children: a retrospective study.
Article in BMC musculoskeletal disorders, 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
objectiveTo identify risk factors for ultrasound-guided closed reduction with percutaneous pinning (CRPP) failure in unstable humeral lateral condylar fractures (HLCFs) in children.
methodThis retrospective study reviewed ultrasound-guided treatment of patients with unstable HLCFs admitted to one hospital from January 2022 to August 2023. The patients were divided into CRPP and CRPP failure groups. Sex, injury side, age, body mass index (BMI), Song classification, Milch classification, subcutaneous ecchymosis, sagittal deviation, interval between injury and surgery (IIS), nighttime surgery, surgery within the first 3 months of surgeon’s experience, and elbow dislocation were identified as risk factors for CRPP failure. Independent risk factors and incidence risk were analyzed.
resultIn total, 158 patients (aged 1–14 years; mean age 5.30 ± 2.35) were enrolled; 22 (13.9%) had CRPP failure. Univariate analysis revealed no significant difference in sex, injury side, BMI, Milch classification, Song classification, subcutaneous ecchymosis, nighttime surgery, and elbow dislocation between groups. The IIS, sagittal deviation, and surgery within the first 3 months of surgeon’s experience showed statistically significant differences between groups. Binary logistic regression analysis revealed that anterior displacement and surgery within the first 3 months of surgeon’s experience were independent risk factors for CRPP failure.
conclusionUltrasound-guided CRPP is prone to failure in patients with unstable HLCFs, an IIS > 5 days before surgery, anterior displacement, and surgery within the first 3 months of surgeon’s experience. These findings can help surgeons make better judgments and preoperative treatment plans for patients with HLCFs.
