Insights
This bibliometric analysis reveals research trends in proximal femoral trabeculae. Future studies should focus on 3D modeling and microarchitecture for improved hip disease evaluation.
Area of Science:
- Orthopedics and Bone Research
- Biomedical Engineering
- Radiology and Medical Imaging
Background:
- Hip disease presents a significant global health challenge, impacting morbidity, mortality, and healthcare expenditure.
- Research on proximal femoral trabeculae is extensive but lacks comprehensive bibliometric analysis.
- Understanding research trends is crucial for advancing the field and addressing hip disease.
Purpose of the Study:
- To conduct a bibliometric analysis of research on proximal femoral trabeculae.
- To identify key research areas, influential publications, and emerging trends.
- To provide insights for future research directions in hip disease and bone health.
Main Methods:
- Bibliometric analysis of 365 publications from 2004-2023 sourced from Web of Science Core Collection.
- Analysis of publication trends, co-authorship, co-citation, and keyword clustering using VOSviewer and CiteSpace.
- Categorization of journals and keywords into distinct research clusters.
Main Results:
- The USA is the leading contributor, with 133 publications and high citation counts.
- The Journal of Bone and Mineral Research is the most co-cited journal.
- Key research clusters include medical imaging, orthopedic research, bone density, and biomechanics, with emerging focus on 3D modeling and microarchitecture.
Conclusions:
- Combining structural parameters with bone mineral density (DXA or QCT) enhances proximal femoral strength evaluation.
- Emerging research trends highlight the importance of three-dimensional analysis, microarchitecture, and bionic implants.
- Future research should explore these advanced techniques for better understanding and managing hip disease.
Introduction:
Hip disease is a global public health issue, associated with high morbidity, mortality, and healthcare costs. Although research on proximal femoral trabeculae has been conducted for over a century, no bibliometric analysis has been carried out. The purpose of this study is to evaluate the existing research landscape, identify emerging trends, and offer insights for future studies.
Method:
The scientific output related to the trabeculae within the human proximal femur from 2004 to 2023 was sourced from the Web of Science Core Collection. Moreover, both the annual publications and cumulative totals over this period were summarized in Excel. The VOS viewer was utilized to analyze co-authorship and co-citation relationship between authors, institutions, countries, references and journals. CiteSpace was used to cluster the keywords and research frontiers in this field.
Results:
A total of 365 publications were extracted, with the USA emerging as the primary contributor to this field, accounting for 133 publications with 5807 total citations, averaging 43.7 citations per publication. The Journal of Bone and Mineral Research has been identified as the most co-cited journal with a total of 1742 citations. The journals can be categorized into 5 distinct clusters, including medical imaging, orthopedic clinical research, research on endocrine and metabolic related diseases, human evolution and anatomy related research, biomechanics and modeling. The keyword with the highest co-occurrence frequency is "bone mineral density". The keywords were stratified into six clusters, including DXA, bone remodeling, diagnosis, titanium alloy bionic cannulated screws, individual trabecula segmentation, and QCT. More recently, the focus has expanded to three-dimensional modeling, falls, microarchitecture, and avascular necrosis.
Conclusions:
Evaluation of proximal femoral strength can be improved by combining structural parameters with bone mineral density by DXA or QCT. Three-dimensional analysis, microarchitecture, and bionic implants are emerging as significant areas of focus and trends for future research.
