Outcome Analysis of Loop Endobutton Repair for Acromioclavicular Joint Dislocation.
Article in Journal of orthopaedic case reports, 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
Introduction: Introduction: Acromioclavicular (AC) joint dislocations represent a frequent injury among young- and middle-aged adults, often resulting from high-energy trauma such as road traffic accidents and falls. While surgical intervention is standard for high-grade (Rockwood III-VI) injuries, the optimal technique remains debated. This study evaluates the clinical and functional outcomes of the Endobutton loop system in the management of acute AC joint dislocations. Materials and Methods: This prospective observational study was conducted at the Department of Orthopaedics, Gandhi Medical College, Bhopal, over 18 months. A cohort of 25 skeletally mature patients presenting with acute Rockwood Grade III to VI AC joint dislocations underwent surgical reconstruction using a closed-loop Endobutton device. Patients were monitored at 2 weeks, 6 weeks, 3 months, and 6 months postoperatively. Outcomes were assessed using the Constant-Murley Shoulder Score (CMS) and Visual Analog Scale (VAS) for pain. Results: The mean age of participants was 41.16 ± 12.25 years, with a marked male predominance (84%). Rockwood Type III was the most frequent presentation (52%). Functional recovery demonstrated a statistically significant progressive improvement, with the mean CMS increasing from 54.68 ± 2.65 at 2 weeks to 90.64 ± 3.59 at 6 months. Simultaneously, mean VAS scores showed a significant reduction from 8.12 ± 0.92 to 1.52 ± 0.50 over the same period. The overall complication rate was low (8%), with no hardware-related failures requiring revision in 92% of cases. Conclusion: The Endobutton loop system is a safe, reliable, and effective surgical method for managing acute AC joint dislocations. It provides stable anatomical reduction, leads to excellent functional recovery, and is associated with minimal post-operative complications across all Rockwood grades.
