Complications After Minimally Invasive vs Open Calcaneal Osteotomy: A Retrospective Study.
Article in Foot & ankle international, 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
backgroundA calcaneal osteotomy is a common component of surgical management for various foot and ankle deformities. Open and minimally invasive surgical (MIS) calcaneal osteotomies can be performed. The purpose of this study was to compare complication rates including infection, wound dehiscence, nerve damage, hardware failure, reoperation, and nonunion between these cohorts.
methodsAll patients who underwent an open or MIS calcaneal osteotomy between March 2021 and July 2024 at a single institution were identified and retrospectively reviewed. All procedures were performed by one of 2 fellowship-trained orthopaedic foot and ankle surgeons on patients >18 years of age at the time of surgery. These procedures were performed in combination with other procedures to correct planus or cavus feet. Demographic information and postoperative complications were recorded for each patient with a minimum of 12 months follow-up.
resultsForty-four patients who underwent open calcaneal osteotomy and 26 patients who underwent MIS calcaneal osteotomy met the inclusion criteria for the current study. Patients were followed for a mean 25.3 ± 11.1 months. There was no significant difference in the rate of nonunion (
conclusionData from the current study indicate that open and MIS calcaneal osteotomy are associated with no difference in major complication rates or amount of calcaneal correction. With the numbers available, no significant difference in total or minor complication rates could be detected after FDR adjustment, though fewer minor wound complications were observed in the MIS cohort (3.8% vs 20.5%). Both approaches were associated with significant improvements in patient-reported function and mobility; significant improvement in pain scores was observed in the MIS cohort only after FDR adjustment. LEVEL OF EVIDENCE: Level IV, retrospective cohort study.
