Bibliometric Map Reveals a Decade of Growing Osteosarcopenia Research

Researchers have published the first comprehensive bibliometric analysis of osteosarcopenia, the geriatric syndrome in which osteoporosis and sarcopenia coexist, mapping a decade of global research output and identifying the field’s dominant themes and remaining gaps. The study, published open access in Discover Oncology on 29 October 2026, combined quantitative mapping of the literature with a narrative synthesis of current evidence.

The team retrieved data from the Web of Science Core Collection and analyzed it using Bibliometrix, VOSviewer, SCImago Graphica, and OriginPro. These tools allowed the authors to chart publication trends, authorship patterns, institutional contributions, and keyword co-occurrence networks. Alongside the bibliometric mapping, they conducted a narrative review synthesizing evidence on the epidemiology, pathophysiology, diagnosis, and management of the condition.

The analysis included a total of 245 publications. Annual publication output and citation impact showed a steady increase over the period examined, a pattern the authors interpret as reflecting growing recognition of the syndrome’s clinical significance. China, Japan, and Australia emerged among the leading contributing countries, and collaboration networks were concentrated around prominent institutions.

Keyword co-occurrence analysis identified four major research clusters: risk factors, diagnostic assessment, therapeutic strategies, and prognosis. These clusters indicate where scientific attention has concentrated and suggest the questions driving current investigation into how bone loss and muscle loss interact in aging populations.

The narrative synthesis indicated that osteosarcopenia is associated with an increased risk of falls, fractures, mortality, and functional decline. This association with adverse health outcomes underlies the syndrome’s increasing recognition as a clinically significant geriatric condition, though the synthesis describes associations rather than established causal effects.

Despite advances in imaging and assessment techniques, the authors found that diagnostic criteria for osteosarcopenia remain inconsistent. This lack of standardization complicates comparisons across studies and may hinder the translation of research findings into clinical practice, making it one of the field’s most pressing problems.

Therapeutically, the review concluded that current approaches are largely extrapolated from those used to manage osteoporosis alone, rather than being developed specifically for the combined bone and muscle deterioration that defines the syndrome. This gap between clinical need and targeted treatment options emerged as a central theme of the analysis.

The authors conclude that future research should prioritize longitudinal studies, mechanistic investigations, and multidisciplinary management approaches to improve clinical outcomes in aging populations. As a bibliometric and narrative review, the study maps the literature and synthesizes existing evidence rather than presenting new clinical trial data, and the published version is an early-access article subject to further edits before the final Version of Record.
