Impact of fixation method on avascular necrosis in talar neck fractures: a retrospective analysis.
Article in European journal of orthopaedic surgery & traumatology : orthopedie traumatologie, 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
purposeTo compare clinical outcomes and complication rates between plate with independent screw fixation versus screw fixation alone in the management of talar neck fractures (AO/OTA 81.2), with a primary focus on avascular necrosis (AVN).
methodsA retrospective review was performed of adult patients who underwent operative fixation of talar neck fractures at a single Level I trauma center between 2017 and 2022, with a minimum follow-up of 3 months. Patients were divided into screw fixation alone (S) and plate with independent screw fixation (PS) groups. The primary outcome was avascular necrosis (AVN). Secondary outcomes included fracture union, post-traumatic arthrosis (PTA), infection, and unplanned reoperation. Multivariable logistic regression was performed to identify factors associated with AVN.
resultsSeventy patients were included (33 S, 37 PS) with no differences in baseline demographics, comorbidities, or injury characteristics (p > 0.05). Union rates were similar between groups (p = 0.23). The incidence of AVN was significantly higher in the S group compared to the PS group (52% vs 22%, p = 0.01). There were no differences in rates of PTA, infection, or reoperation (p > 0.05). On multivariable analysis, plate fixation was associated with a significantly lower likelihood of AVN (OR 0.16, 95% CI 0.03-0.70; p < 0.01).
conclusionIn this retrospective cohort, plate with independent screw fixation was associated with a significantly lower risk of avascular necrosis compared to screw fixation alone in talar neck fractures, while maintaining similar union and complication rates.
