Objective:Based on Web of Science database, this study aimed to explore the current status, research hotspots and development trends of countries regarding clinical management of osteoporotic fractures using bibliometrics and visualized analysis.Methods:We collected literatures in the field of clinical management of osteoporotic fractures included in Web of Science database, and applied bibliometrics to analyze the publication dates, countries, institutions, journals, authors, highly cited literatures and research hotspots. Visualization was drawn by VOSviewer software.Results:Analysis of the 2 508 articles revealed 3 types of data. (1) The analysis of basic information of the literature showed that: ①The country with the largest number of publications was the United States, which published 672 articles, followed by the United Kingdom and Canada, and China ranked fourth; ②The top three authors in the number of publications were Kanis JA, Cooper C and McCloskey EV respectively; ③The institution with the highest number of publications was the University of Sheffield, UK, followed by the University of Southampton, UK and the University of Toronto, Canada. (2) Network visualization of highly cited literatures showed that 118 highly cited literatures were mainly divided into 5 clusters, which were related to osteoporotic fracture diagnosis, treatment, medication adherence, management consensus and strategies of preventing refracture. (3) Temporal overlay visualization of research hotspots showed that early research mainly focused on traditional therapeutic drugs, and current research hotspots were mainly molecular targeted drugs, trabecular bone score and fracture liaison services.Conclusion:This study shows that the research activity of clinical management of osteoporotic fractures is increasing worldwide, and there is still a huge gap between China and Europe or the United States. Current research hotspots and development trends mainly focus on molecular targeted drugs, osteoporotic fracture treatment concepts, emerging fracture risk assessment tools, and fracture prevention and management models.

Objective:To compare the numerical rating scales (NRS) and Oswestry disability index (ODI) of denosumab in Chinese postmenopausal osteoporosis patients after 3 months, and analyze the early adverse reactions to provide reference for clinical diagnosis and treatment.Methods:Using a prospective study method, 260 patients with postmenopausal osteoporosis who were outpatients and inpatients in the Second Affiliated Hospital of Soochow University from September 2020 to October 2021 were selected, and general information, including age, height, weight, bone mineral density, history of fragility fractures, and use of anti-osteoporosis drugs. All subjects received denosumab 60 mg subcutaneously, and were given calcium and vitamin D at the same time. Pain was scored by NRS before treatment and 3 months after treatment, and functional improvement was assessed by ODI.Results:After 3 months of denosumab treatment in postmenopausal women with osteoporosis, among patients with different age groups, different degrees of osteoporosis, history of fragility fractures, and history of use of anti-osteoporosis drugs, NRS score and ODI score were lower than those before treatment, and the difference was statistically significant ( P<0.05). In addition, in patients with a history of fragility fractures (mainly vertebral fractures), the NRS scores and the ODI score decreased more significantly, and the difference was statistically significant ( P<0.05); the NRS score and ODI score decreased more significantly in patients with severe osteoporosis than in patients with osteoporosis, and the difference was statistically significant ( P<0.05); the BMD value of lumbar spine was negatively correlated with the reduction of NRS score before and after treatment ( P=0.042). In this study, 260 patients had musculoskeletal pain in 6 (2.3%), fatigue in 5 (1.9%), rash in 4 (1.5%), urinary tract infection in 2 (0.7%), and dizziness in 2 (0.7%), 2 case of fever (0.7%), 1 case of hypocalcemia (0.4%), a total of 22 cases of adverse reactions were reported, and the overall adverse reaction rate was 8.5%. Conclusion:Denosumab can improve pain symptoms and functional disability early in the clinical application of Chinese postmenopausal women with osteoporosis, and the incidence of adverse reactions is low. Especially for postmenopausal female osteoporosis patients with severe osteoporosis, low lumbar spine bone density, and a history of fragility fractures (mainly vertebral fractures), the application effect is more significant.
