An Unusual Case of Onlay Reverse Shoulder Arthroplasty Disassembly Due to Cement Interposition. A Case Report.
Article in Journal of orthopaedic case reports, 2023. 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: Reverse shoulder arthroplasty (RSA) complication rates range between 1.4% and 28% depending on the nature of the indication. Even though glenosphere dissociation is the third most frequent complication after RSA, with an incidence that can rise to just over 12%, there is no evidence in the literature describing the disassembly between the humeral stem and its metaphysics. Case Report: It is reported a novel early failure type in a reversed shoulder arthroplasty of a healthy 72-year-old female patient, involving the disassembly of the metaphysis from an onlay tray system due to cement interposition in a reversed shoulder prosthesis. Conclusion: This case highlights a rare form of early failure after RSA as a result of a disassembly between the humeral stem and its metaphysis due to the presence of interposed cement. To prevent this complication, a two-step implantation procedure is recommended, which consists of cementing the stem before inserting the metaphyseal tray.
