Incidence, Risk Factors, Management, and Nonunion Rates of Pediatric Scaphoid Fractures: A National Database Study.
Article in Journal of the American Academy of Orthopaedic Surgeons. Global research & reviews, 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
purposeScaphoid fractures are often complicated by nonunion, but incidence, risk factors, and management have not been well-characterized for pediatric patients.
methodsPatients aged <18 years with scaphoid fracture were identified in the 2015 to 2023 PearlDiver M170 database. Patient and fracture characteristics, imaging, and surgeries were extracted. Predictive factors for nonunion were characterized with multivariable analyses. Among patients with nonunion, characteristics of those receiving surgical and nonsurgical management were compared with multivariable analyses.
resultsOf 26,364 pediatric scaphoid fractures, 64.5% were male, with an average age of 13.54 years. Of fractures with displacement and location specified, 22.8% were displaced and distal, middle, and proximal third fractures constituted 45.4%, 45.7%, and 8.9%, respectively. MRI was used for 11.5% and CT for 8.6%. Nonunion occurred in 1102 patients (4.2%). Nonunion was independently associated with clinical characteristics (older age [OR = 1.57 per year], male sex [OR = 2.11], and overweight/obesity [OR = 1.52]), nonclinical characteristics (relative to Northeast, Midwest region OR = 1.45), and fracture characteristics (displacement [OR = 2.45] and position [relative to distal, middle OR = 2.18 and proximal one third location OR = 4.74]) (P < 0.0003 for all). Of nonunions, 73% were diagnosed within 3 months of first fracture diagnosis. Of patients with nonunion, 784 (71.3%) had surgery. Surgery was independently associated with older age (OR = 1.15 per year) and Midwest region (relative to West, OR = 1.96) (P < 0.0063 for all).
conclusionPediatric scaphoid fracture patient and fracture characteristics roughly mirrored adult populations. The occurrence of most nonunion diagnoses shortly after initial fracture diagnosis suggests that many patients with nonunion presented late to care.
