Management and clinical outcomes of Dubberley type A capitellar fractures.
Article in Journal of clinical orthopaedics and trauma, 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
Aims: Capitellar fractures are uncommon, accounting for 0.5-1 % of all elbow fractures. These fractures are best managed surgically to restore articular congruity. Dubberley type A fractures treated with anterolateral or lateral surgical approaches have been associated with high complication rates. The 'Global' approach to elbow has been conceptualised in order to comprehensively approach elbow injuries. The aim of this study was to evaluate the clinical outcomes of fractures of the capitellum treated using global surgical approach. Methods: Data was prospectively collected for all patients presenting between 1998 and 2020.Patient's demographics, mechanism of injury, Mayo Elbow Performance Index MEPI, Grip Strength and radiographs were retrospectively collected and analysed. Results: 31 patients met the inclusion criteria with a mean age of 47yrs (IQR 12-81yrs) years, 18 males: 13 female patients. According to Dubberley classification, 24 were type I, 5 were type II and 2 were type III. 4 patients sustained associated collateral ligament injuries and 2 patients had radial head fractures. Global approach with an inside Kaplan approach was used in 26 patients, others were treated with an inside Kocher or anterior approaches. Almost all fractures were fixed using headless screws alone (n = 25),6 patients had fixation augmented with bioabsorbable rods or a posterior buttress plate. Mean follow up was 46 months. Mean MEPI was 89 (SD8), Extension 9.35 ± 5.32, Flexion 130.29 ± 8.7, Pronation 59.16 ± 7.034, Supination 63.97 ± 7.1. Mean Grip strength was 22.94 ± 4.5. These were significantly better following surgery (p < 0.001). Further surgery was only required in 1 case for stiffness. Overall complication rate was 9.6 %. There were no infections or cases of instability following fixation. Conclusion: This study is one of the largest case series reporting good functional outcomes in Dubberley type A fractures treated with headless screws using global surgical approach. We report lowest complication rate,100 % fracture union rate and good MEPI scores.
