Clinical efficacy analysis of elastic fixation for isolated ligamentous Lisfranc injuries.
Article in BMC surgery, 2025. 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
backgroundElastic fixation represents a novel approach to managing Lisfranc injuries. This study aims to evaluate the clinical efficacy of elastic fixation for such injuries using imaging, clinical evaluation indices, and plantar pressure analysis.
methodsThis retrospective study included 15 patients with isolated ligamentous Lisfranc injuries who underwent elastic fixation between October 2022 and July 2024.Follow-up lasted ≥ 6 months. Weight-bearing foot X-rays were taken at 1, 3, and 6 months postoperatively to assess joint reduction, degeneration, and implant stability. American Orthopaedic Foot and Ankle Society (AOFAS) scores and Foot Function Index (FFI) were collected preoperatively and at 1-6 months postoperatively. Plantar pressure distribution was also measured.
resultsImaging showed stable reduction of the tarsometatarsal joints without degeneration or implant failure in all patients. Clinical scores improved significantly: AOFAS scores from 37.6 ± 6.75 to 92.9 ± 0.96 (P < 0.0001), and FFI from 151.7 ± 9.31 to 10.1 ± 2.59 (P < 0.0001) by 6 months postoperatively. Plantar pressure analysis revealed the affected foot's pressure contribution increased from 20.4% preoperatively to 50.4% at 6 months postoperatively. By 2 months postoperatively, pressure distribution between both feet was balanced (P > 0.05).
conclusionsIn this highly selected cohort, elastic fixation achieved excellent short-term functional recovery and allowed early weight-bearing. Owing to the small sample and short follow-up, these findings are exploratory and hypothesis-generating rather than definitive. Larger, longer-term studies are required to validate the safety and generalisability of the technique across broader patient populations.
