Impact of single versus dual arterial supply on perfusion and function in finger replantation after complex hand injuries.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Finger amputations following complex hand injuries (CHI) pose a significant challenge in hand surgery due to severe tissue trauma and neurovascular damage, necessitating precise arterial repair. While restoring arterial perfusion is critical, it remains unclear whether reconstructing both proper palmar digital arteries is required for optimal outcomes. This study evaluates whether restoring one or both arteries in finger replantation after complex injuries impacts perfusion and overall outcomes. In this retrospective, cross-sectional, follow-up study, we investigated patients with finger amputations following CHI admitted to the high-volume regional hand trauma center between January 2013 and December 2020. Perfusion has been assessed using FLIR thermal imaging and laser speckle contrast analysis. Functional outcomes and quality of life scores were measured using standardized questionnaires. Sensory assessments, along with pain and grip strength measurements were also conducted. A total of 31 patients were included in the study. Thermal imaging showed a significantly higher finger surface temperature in patients with two-artery reconstruction. Laser speckle contrast analysis confirmed better perfusion, though not statistically significant. Functional and quality-of-life scores were similar across groups, except for significantly improved temperature sensation in the two-artery group. In conclusion, reconstructing both arteries in finger replantation following CHI isn't essential for good outcomes if one artery provides adequate perfusion, but dual reconstruction may improve perfusion and temperature sensation.
