Risk of nonunion for dual plate versus single plate fixation for humeral shaft and distal humerus fractures: a systematic review and meta-analysis.
Synthesis in European journal of orthopaedic surgery & traumatology : orthopedie traumatologie, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
objectiveThis study's purpose was to compare clinical outcomes in adult patients who underwent dual plate versus single plate fixation for humerus fractures to enhance decision-making and patient care.
methodsData sources: A pre-registered systematic review and meta-analysis searched four databases on January 9th, 2025. Inclusion criteria were studies that compared dual versus single plate fixation for humerus fractures. Outcomes included risk of nonunion, risk of total complications, and time until union after surgery. A random effects meta-analysis was done using risk ratio (RR) or unstandardized mean difference.
resultsThirteen moderate quality retrospective studies were included out of 211 articles retrieved. Patients (n = 788; 47.8% male) had an average age of 50.4 ± 14.2 years and an average follow-up time of 18.1 ± 14.4 months with 378 patients (48.0%) receiving dual plate fixation and 410 patients (52.0%) receiving single plate fixation for humerus fracture (38.4% distal humerus; 61.7% humeral shaft). There was no statistically significant difference in risk of nonunion between dual and single plate fixation groups (p = 0.502; RR: 0.99; 5.0% vs.7.3%). For subgroup analysis by location, there was no statistically significant difference in risk of nonunion for distal humerus fractures or humeral shaft fractures, by surgical indication for risk of nonunion for primary fracture or nonunion, or by surgical indication for time until union for primary fracture or nonunion. There was no statistically significant difference in total complications in all subgroups, except dual plate had an increased risk of total complications versus single plate for distal fractures (p = 0.014; RR: 1.40).
conclusionThere may be no clinically meaningful differences in risk of nonunion, risk of total complications, and time until union between dual plate versus single plate fixation for humerus fractures in adult patients.
