Minimally invasive surgery in the correction of recurrent hallux valgus: a case series with 2‑year follow‑up.
Article in BMC musculoskeletal disorders, 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
objectiveRecurrent deformity following surgical correction remains a complex and technically demanding condition. This study aimed to evaluate the clinical and radiographic outcomes of minimally invasive surgery (MIS) in patients undergoing revision procedures for recurrent hallux valgus (HV).
methodsThis retrospective case series included 33 feet that underwent minimally invasive revision surgery using either the third generation Minimally Invasive Chevron-Akin (MICA) or the fourth-generation Metaphyseal Extra-Articular Transverse and Akin osteotomies (META), following failure of a previous hallux valgus correction performed by open or minimally invasive techniques. Clinical outcomes were assessed using the Manchester-Oxford Foot Questionnaire (MOXFQ), the Visual Analogue Scale (VAS) for pain, and patient satisfaction. Radiographic parameters and complications were recorded and statistically analysed using R software.
resultsBoth techniques proved effective in angular correction, with significant reductions in the hallux valgus angle (HVA) and intermetatarsal angle (IMA) (p < 0.001), as well as in bone and soft-tissue forefoot width (p < 0.05). Significant improvements were also observed in all three MOXFQ domains (p < 0.001) and in VAS scores (p < 0.001). Subgroup analysis revealed no statistically significant differences between MICA and META in either radiographic or clinical outcomes related to pain and function (p > 0.05).
conclusionThird- and fourth-generation minimally invasive surgical techniques have proven effective in correcting radiographic parameters and improving pain and functional scores in patients undergoing revision for recurrent hallux valgus, with a low rate of complications. LEVEL OF EVIDENCE: Level IV, retrospective case series.
