A single-center retrospective observational study of modified anterolateral arthroscopic double-loop plate fixation for acute acromioclavicular joint dislocation.

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
This study aimed to evaluate the clinical efficacy of double-loop plate fixation via the subacromial coracoid approach (modified anterolateral shoulder arthroscopy) for acute acromioclavicular joint dislocation of Rockwood Grade III or higher. A retrospective single-center observational study included 68 patients treated at Weifang People's Hospital from October 2022 to April 2024. Outcomes included pre- and postoperative pain (Visual Analog Scale), functional recovery (Constant Score), range of motion, and radiographic reduction (coracoclavicular distance [CCD] and acromioclavicular distance [ACD]). Repeated-measures analysis of variance evaluated longitudinal changes; paired t-tests compared CCD and ACD between 2 days and 6 months postoperatively. P < .05 was considered significant. All 68 patients completed ≥ 6-month follow-up. Significant improvements were observed in Visual Analog Scale, Constant Score, and range of motion at 1, 3, and 6 months postoperatively (all P < .01), with stable CCD and ACD radiographically. The modified arthroscopic double-loop plate fixation shows short-term efficacy in acute Rockwood III-VI acromioclavicular joint dislocation, with pain relief, functional recovery, and stable radiographic reduction. Limitations include retrospective, single-center design, lack of comparator, and short-term follow-up; long-term efficacy requires prospective controlled trials.
