3D-Planned Posterior Open-Wedge Glenoid Osteotomy Using a Patient-Specific Cutting Guide in Posterior Shoulder Instability: A Technical Note.
Article in Cureus, 2025. 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
Posterior shoulder instability remains a rare but disabling condition often underdiagnosed due to subtle symptoms and delayed presentation. Excessive glenoid retroversion is a key anatomical determinant of posterior humeral head subluxation. When isolated soft tissue repair fails, posterior opening glenoid osteotomy can restore physiological glenoid version. Traditional freehand or fluoroscopic techniques, however, are technically demanding and prone to variability. This technical note describes a 3D-planned posterior open-wedge glenoid osteotomy using a patient-specific cutting guide (PSI) to correct excessive retroversion in posterior instability. Preoperative 3D computed tomography (CT) planning (ONE®, Newclip Technics, Haute-Goulaine, France) allows the virtual correction of retroversion and design of a custom guide conforming to the posterior glenoid surface. The PSI ensures accurate orientation, safe osteotomy execution, and faithful translation of the preoperative plan. Fixation is achieved with a low-profile locking plate, enabling early mobilization.
