Treatment of adult neglected clubfoot with Ponseti method: Consecutive case series of thirty-three feet.
Article in PloS one, 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
backgroundThere are no prior case series of untreated adults with neglected clubfoot treated with the Ponseti method, and the oldest previously reported case was 30 years old. The objective of this study was to analyze the outcomes of Ponseti treatment in adults with neglected clubfoot.
methodsThirty patients were initially treated using the Ponseti method. Twenty-one patients (33 feet; mean age, 34 years; range, 21-53 years) had at least 12 months of follow-up and were included in the final analysis. Additional bone surgery was performed only in feet that were not fully corrected after serial cast changes and Achilles tenotomy. Statistical analysis was used to correlate the following: number of casts; pre-treatment flexibility and foot rotation; age; additional bone surgery beyond tenotomy; sex; residual deformity; forefoot abduction before tenotomy; and results according to AOFAS score.
resultsA total of 85% had rigid or mildly flexible feet. A mean of 11.6 casts (3-25) were performed before the Achilles tenotomy. A total of 33% had additional bone surgery after the Ponseti method (casts and Achilles tenotomy). There was a significant improvement in the AOFAS score (32-79) in a mean follow-up of 32 months. More flexible feet required fewer cast changes and showed better outcomes (p < 0.05). Older age and lower forefoot abduction values after the cast period were positively correlated with the need for additional bone surgery (p < 0.05). The percentage of residual deformity was significantly higher in males (p = 0.03).
conclusionThe method applied proved to be a viable and effective alternative for the treatment of neglected clubfoot in adults.
