Sarcopenia of the deltoid as an indicator of outcome following reverse total shoulder arthroplasty: a systematic review and meta-analysis.
Review in JSES international, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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) is increasingly utilized for managing rotator cuff tear arthropathy, shoulder osteoarthritis, and proximal humerus fractures. The deltoid generates the key mechanical force after rTSA. The functional success of a rTSA is dependent on the status of the deltoid muscle. Sarcopenia, defined as age-related loss of skeletal muscle mass and function, has been linked to poor outcomes in various surgical contexts. This systematic review investigates the impact of radiologically measured deltoid sarcopenia on functional and patient-reported outcomes following rTSA. Methods: A systematic search of MEDLINE, PUBMED, and SCOPUS was conducted to identify studies assessing deltoid sarcopenia via radiological imaging in rTSA patients. Inclusion criteria included studies reporting both radiological measurements of the deltoid and functional or patient-reported outcome measures. Risk of bias was assessed using the Newcastle-Ottawa Scale and the Methodological Index for Nonrandomized Studies. Results: Fourteen studies comprising 1,681 shoulders were included. Studies ranged from 2010 to 2024. Eight studies used a prosthesis based on the Grammont concept design, four studies used a reduced neck shaft angle of 135°, and two studies in which the prosthesis was not stated. Radiological modalities included magnetic resonance imaging, Computed Tomography, ultrasound, and X-ray, with deltoid cross-sectional area being the most frequently measured parameter. Meta-analysis revealed a weak, nonsignificant association between preoperative deltoid cross-sectional area and postoperative Constant-Murley Score (r = 0.12, Conclusion: Radiological evidence of deltoid sarcopenia correlates with suboptimal functional and patient-reported outcomes after rTSA, the pooled effects of which are not statistically significant. However, methodological heterogeneity and inconsistent use of sarcopenia metrics limit the generalizability of these findings. Standardized imaging protocols and sarcopenia definitions are essential for improving predictive accuracy and guiding clinical decision-making.
