Rise in radial head arthroplasty utilization in young patients: an analysis of the Nationwide Ambulatory Surgery Sample.
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: Utilization of radial head arthroplasty (RHA) has increased in recent years, but national age-specific trends in ambulatory RHA use in the United States have not been described. The purpose of this study was to evaluate national trends in ambulatory RHA by age. Methods: The Nationwide Ambulatory Surgery Sample (2016-2022) was used to identify adults (≥20 years) undergoing ambulatory RHA for isolated acute radial head or neck fractures. Patients were stratified by age (20-39, 40-59, and ≥60 years). Descriptive statistics and sample-weighted regression models were used to assess temporal trends and factors associated with younger age at surgery. Age- and sex-adjusted national incidence rates were calculated using negative binomial regression. Results: A weighted total of 13,453 patients were identified, of which 20.3% were young (20-39 years), 35.9% middle-aged (40-59 years), and 43.9% elderly (≥60 years). Annual ambulatory RHA volume increased from 1,657 cases in 2016 to 2,289 cases in 2022 (+38.1%). The greatest relative increase occurred in young patients (+58.2%), compared with elderly (+47.0%) and middle-aged (+19.5%) patients. Age- and sex-adjusted incidence increased significantly in young patients (0.45 to 0.54 per 100,000; incidence rate ratio: 1.21; 95% confidence interval (CI): 1.05-1.39; Conclusion: Overall ambulatory RHA utilization in the United States increased from 2016 to 2022, most significantly in young adults. These findings demonstrate increasing ambulatory utilization of RHA among young adults and highlight the need for longitudinal studies evaluating implant durability, revision risk, and functional outcomes in this population. Whether this trend reflects changes in treatment patterns, referral practices, outpatient migration, or other factors also warrants further investigation.
