Extraanatomical revascularization via dermatodermal fusion in pediatric proximal fingertip amputations: A cohort study.

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: Proximal fingertip amputations in zones 3 and 4, according to the Allen classification, pose a significant challenge in children due to the technical difficulty of performing microvascular anastomosis on small vessels. The goal of this study was to evaluate the effectiveness of dermatodermal fusion as an alternative method for revascularizing amputated fingertips in young children. Methods: In the current study we present a series of 10 children treated with dermatodermal fusion for proximal fingertip amputations with a mean age of 2.9 years [range: 9 months to 7 years] in one center between 2015 and 2024. Results: The average age of children with fingertip amputations in zones 3 and 4 was 2.9 years. The surgical technique involved partial-thickness dermabrasion of both the amputated fingertip and a donor site, followed by the fusion of these surfaces. Postoperative care included weekly dressing changes, with surgical separation performed once stable reperfusion was achieved, typically within 3-5 weeks. The results indicated a successful revascularization rate of 80%, with full regrowth in 8 out of 10 patients. Younger children demonstrated better outcomes, supporting the hypothesis that age is a significant factor in regenerative capacity. Discussion: Dermatodermal fusion offers a simple, effective approach to fingertip replantation, particularly when microsurgical resources are not available. Further studies with larger sample sizes are warranted.
