Efficacy of 3D-printed surgical guides in the correction of pediatric cubitus varus deformity: a systematic review and meta-analysis.
Review in JSES international, 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
Background: Cubitus varus is a frequent post-traumatic deformity in children, typically resulting from malunion of supracondylar humeral fractures. Despite the availability of various osteotomy techniques, achieving precise and reproducible correction remains challenging. Recently, 3-dimensional (3D) printing-guided osteotomy has gained attention for improving surgical accuracy and outcomes. This study aimed to systematically evaluate the clinical effectiveness and safety of 3D-guided corrective osteotomy in pediatric cubitus varus in comparison with conventional surgical techniques. Methods: We performed a systematic review and meta-analysis of studies published between 2000 and 2025 that investigated the use of 3D printing-assisted, patient-specific instrumentation in corrective osteotomy for pediatric cubitus varus. Databases searched included PubMed, Scopus, and Web of Science. Both single-arm and comparative studies reporting clinical, radiographic, and operative outcomes were included. Methodological quality was assessed using the Methodological Index for Non-Randomized Studies (MINORs) criteria. Results: Twelve studies involving 206 pediatric patients were included, comprising 2 prospective and 10 retrospective studies. In the single-arm meta-analysis, 81.9% of patients achieved excellent outcomes, with a pooled complication rate of 7.8%. A comparative analysis revealed a significantly higher likelihood of excellent outcomes in the 3D group compared to conventional techniques (risk ratio = 1.33; 95% confidence interval: 1.05-1.69), while complication rates and humerus-elbow-wrist angle correction were similar between the groups. Conclusion: 3D printing-guided corrective osteotomy appears to offer high success rates and low complication rates in treating pediatric cubitus varus, with potential advantages over conventional techniques. Further prospective studies are needed to confirm these findings and guide clinical adoption.
