Short- to midterm outcomes of stemless reverse total shoulder arthroplasty: a systematic review.
Review in Journal of shoulder and elbow arthroplasty, 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
Background: Reverse total shoulder arthroplasty (rTSA) using stemless humeral components is gaining popularity. Advantages include humeral bone preservation, reduced operative time, and decreased blood loss. However, stemless implants may increase malpositioning and component loosening rates. We evaluated outcomes following stemless rTSA. Methods: Comprehensive screening of EMBASE, PubMed, and MEDLINE until June 2024 for studies reporting stemless rTSA clinical outcomes was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Included studies were assessed for methodological quality using the Methodological Index for Non-Randomized Studies (MINORS) instrument. Outcomes included demographics, functional outcomes, patient-reported outcome measures, complications, and radiographic outcomes. Stemmed and stemless implant comparisons in cohort studies were pooled for analysis. Results: Thirteen studies with moderate methodological quality were included. Five hundred ninty-two patients (598 shoulders) provided a mean follow-up of 41.8 months and age of 70.6 years. Weighted mean improvement in flexion, abduction, and Constant score were +47.8°, +42.5°, and +31.7, respectively. Complication, reoperation, scapular notching, and asymptomatic humeral component loosening rates were 14.3%, 7.0%, 17.7%, and 3.3%, respectively. Among stemless and stemmed rTSA comparative studies, no differences in patient-reported outcome measures, functional outcomes, and complications were noted. Conclusion: Stemless rTSA improved clinical outcomes, with similar complications and reoperation rates to stemmed designs. Further comparative and registry-based studies should evaluate long-term stemless rTSA outcomes.
