Utilisation of the minimally invasive chevron akin (mica) osteotomy for severe hallux valgus: a systematic review.
Synthesis in Musculoskeletal surgery, 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
BACKGROUND AND
aimHallux valgus is the most common forefoot disease that can cause pain and be disabling for the patient. Many surgical procedures have been described to correct this deformity; over the last years, the minimally invasive Chevron and Akin osteotomies (MICA) technique has become very popular. The aim of this review was to assess if MICA technique is a reliable procedure for treating severe hallux valgus.
methodsA systematic review was performed according to the Preferred Reporting Items for systematic Reviews and Meta-Analysis (PRISMA) guidelines. The keywords were searched in PubMed Medline and Cochrane library. To minimise the number of missed studies, no filters were applied to the search strategy. To be considered for this review, the articles needed to comply with the following inclusion criteria: Minimally invasive Chevron and Akin osteotomy (MICA) for severe hallux valgus (HVA > 40°, IMA > 16°), patient age over 18 years and minimum follow-up of 6 months.
resultsFollowing the PRISMA flow chart 7 studies met the inclusion criteria and were taken into consideration in the review. We reached a population of 582 patients for a total of 676 feet. Males and females were 64 and 518, respectively. The mean age was 54.15 ± 8.25. The mean follow-up was 23.74 ± 9.60 months. All the studies reported an improvement in clinical results, in terms of function and quality of life. Radiological variables, mostly IMA and HVA, assessed pre- and postoperatively showed significant improvement in all studies included.
conclusionsDespite the limited number of published studies in the literature, the available evidence reveals good clinical outcomes and high levels of patient satisfaction. Percutaneous surgery for severe hallux valgus can achieve great deformity correction with reasonable rates of residual deformity. Patient satisfaction and quality of life following third-generation MICA surgery is very high.
