Is horizontal stabilization necessary in chronic acromioclavicular reconstructions?
Article in JSES 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
Background: The role of horizontal acromioclavicular (AC) stabilization in chronic AC dislocation reconstructions remains uncertain. While commonly used techniques focus on coracoclavicular (CC) ligament reconstruction, the potential benefit of adding horizontal AC stabilization has not been clearly established. The aim of this study was to evaluate whether horizontal AC stabilization in chronic AC dislocations treated with CC ligament reconstruction improves clinical outcomes, reduces failure, complications, or revisions, and enhances radiographic reduction. Methods: A retrospective multicenter study included 209 patients (mean age 44.5 ± 14.1 years, 90.9% male) who underwent CC ligament reconstruction (Weaver-Dunn, anatomic biologic reconstruction, or synthetic ligament) between 2006 and 2024. Patients were stratified according to the addition of horizontal AC stabilization. Primary outcome was the Constant score at final follow-up. Secondary outcomes included Subjective Shoulder Value, visual analog scale pain, radiographic AC distance, failures, complications, and revisions. Multivariate linear regression and 1:1 propensity score matching were performed. Results: Horizontal AC stabilization was not associated with higher Constant scores (β = -1.2, Conclusion: Horizontal AC stabilization in chronic AC dislocations treated with CC ligament reconstruction does not significantly improve clinical outcomes or reduce failures, but it appears to lower complication rates and provide superior radiographic reduction. These results suggest a potential stabilizing benefit of horizontal AC fixation, although further prospective studies are needed to validate its clinical relevance.
