Depicting developing trend and core knowledge of hip fracture research using bibliometric and visualized analysis

Abstract

Background Among all osteoporotic fractures, hip fracture is common and carries high morbidity and mortality. We aim to analyze the present status and worldwide trends of hip fracture research in various clinical aspects.Methods Publications from 2010 to 2019 were retrieved from Web of Science database and analyzed through bibliometric methodology. The software VOS viewer was utilized for visualized analysis.Results Totally, 6139 publications were included, and publications increased annually, from 152 (2000) to 592 (2019). The USA has made huge contributions with the most publications, the highest H-index, and citations. Osteoporosis International has published the most papers. Leading researchers, contributing institutions, their cooperation relationships and scientific masterpieces have been identified. Research could be divided into five clusters: "mortality", "surgical management", “rehabilitation”, “osteoporosis” and "epidemiology". A clear developing trend was described, which initiated from fracture epidemiology and prevention, transitioned to perioperative management, orthogeriatric care and patient safety, and then to functional recovery, disease burden along with national audit and initiatives in recent time.Conclusions Hip fractures resulted in conditions that extend far beyond orthopaedics, concerning epidemiology & preventive medicine, internal medicine & endocrinology, as well as critical care and gerontology. And a growing volume of publications in the future could be expected.
