3D-assisted arthroscopic management of subacromial impingement: A clinical outcome study.
Article in SICOT-J, 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
introductionThe clinical value of three-dimensional (3D)-assisted planning in arthroscopic acromioplasty remains unclear, particularly regarding its ability to optimize subacromial decompression and improve clinically meaningful outcomes. PURPOSE: To evaluate whether 3D-assisted preoperative planning can improve radiologic parameters and functional outcomes in patients undergoing arthroscopic treatment for subacromial impingement syndrome. STUDY
designDescriptive observational study (combined retrospective and prospective).
methodsFifty patients with subacromial impingement syndrome underwent arthroscopic acromioplasty with 3D-assisted preoperative planning. Clinical outcomes were assessed using the UCLA score. Radiologic parameters, including acromial index (AI), critical shoulder angle (CSA), lateral acromial angle (LAA), and acromiohumeral distance (AHD), were evaluated using static and dynamic 3D computed tomography preoperatively and postoperatively.
resultsPostoperatively, AI and CSA significantly decreased toward normal ranges, while LAA improved. Both static and dynamic AHD increased significantly, indicating enhanced subacromial space. The mean UCLA score improved from 21.54 ± 2.66 to 33.22 ± 1.75 (p < 0.01).
conclusion3D-assisted arthroscopic acromioplasty was associated with significant improvements in both radiologic parameters and functional outcomes. The ability to evaluate subacromial space dynamically and localize impingement sites may facilitate more precise and individualized decompression, potentially enhancing surgical effectiveness.
