Glenoid defects in revision shoulder arthroplasty may be treated with coracoid autograft with reliable short-term results.

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: Glenoid bone defects are common after failed arthroplasty or fracture fixation. Allograft or autograft reconstruction may be used to fill defects, however, may have increased failure rates or add to patient morbidity, respectively. We hypothesize that coracoid autograft can effectively fill contained glenoid defects and secondarily hypothesize that coracoid autograft has a low failure rate in early post-operative follow-up. Methods: A retrospective chart review was performed of all patients receiving coracoid autograft for glenoid bone defects during revision shoulder arthroplasty at a single institution, performed by 2 surgeons between 2020 and 2024. Pre-operative radiographs and computed tomography scans were analyzed to describe coracoid morphology and glenoid bone defects. Post-operative radiographs were analyzed for distalization shoulder angle, lateralization shoulder angle, and lateral humeral offset. Patient demographics and pre-operative and post-operative patient-reported outcome measures were collected. Results: Twenty-seven patients met criteria and were included for analysis. The average patient age was 67.2 ± 9.7 years (range 39-83 years). Average follow-up was 5.0 ± 4.6 months (range 1-17 months). Revisions were performed for the following indications: 9 (33.3%) patients with a failed hemiarthroplasty or hemiarthroplasty antibiotic spacer, 8 (29.6%) failed anatomic total shoulder arthroplasties, 8 (29.6%) reverse shoulder arthroplasties with baseplate failure, and 2 (7.4%) patients with post-traumatic glenoid injury from failed open reduction internal fixation.The average coracoid volume was significantly greater than the average defect volume ( Conclusion: The coracoid is a viable autograft option for contained glenoid defects, showing similar dimensions to glenoid vault bone loss and no appreciable failures in early post-operative follow-up. The use of this specific autograft avoids morbidity and complications from iliac crest harvest, though longer follow-up is required to evaluate longitudinal risk of baseplate failure.
