Does the rate of revision vary in primary total stemmed anatomic shoulder arthroplasty with short or conventional humeral stems?
Article in JSES international, 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: Primary total stemmed anatomic shoulder arthroplasty (aTSA) with either short (<10 cm) or conventional length (≥10 cm) humeral stems undertaken for osteoarthritis were compared to determine the rates of all cause revision. Methods: Between December 1, 2006, and December 31, 2023, all short or conventional humeral stemmed aTSAs were compared from a large national arthroplasty registry by Kaplan-Meier estimates of survivorship and hazard ratios from Cox proportional hazard models adjusted for age, gender, humeral head size, humeral fixation, glenoid component type, glenoid augmentation, polyethylene type, and surgeon volume. Possible interactions were examined. Results: The cumulative percent revision at 13 years was 19.4% (95% confidence interval; 17.0-22.1) for short total shoulder arthroplasty (n = 4,550), 13% (95% confidence interval; 9.6-17.4) for long aTSA (n = 2,447). Long aTSA had a higher rate of revision compared to short aTSA (1.5 years+: Conclusion: Modern primary aTSA outcome for osteoarthritis is affected by the humeral stem length and glenoid polyethylene. Technical challenges may explain the relative underperformance of short stem components in the short term rather than intrinsic characteristics.
