Combination of midfoot derotational osteotomy and ankle arthrodesis against neglected clubfoot: a case report.
Article in Journal of surgical case reports, 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
Neglected congenital clubfoot in adults is difficult to manage. Multi-joint arthrodesis is often required but is invasive and associated with complications. We report an adult case treated with ankle arthrodesis and midfoot derotational osteotomy. A 59-year-old man with untreated idiopathic clubfoot since birth presented with severe hindfoot varus and rigid midfoot inversion, leading to wheelchair dependence. Imaging showed correctable hindfoot deformities but rigid midfoot inversion with talonavicular subluxation. Surgery consisted of Achilles tendon lengthening, ankle and subtalar arthrodesis with a retrograde intramedullary nail, and midfoot derotational osteotomy, resulting plantigrade. Bony union was confirmed at one year. At 3 years, plantigrade alignment remained without recurrence. Callosities resolved, and the patient regained pain-free walking. Clinical scores improved: Japanese Society for Surgery of the Foot ankle/hindfoot (4.0 to 66.0), Japanese Society for Surgery of the Foot midfoot (0.0 to 73.0), self-administered foot evaluation questionnaire (89.2 to 366.0). This is the first report of midfoot derotational osteotomy for neglected congenital clubfoot, offering a less invasive option for selected adults.
