Navigational template applied in the orthopaedic field in China: a bibliometric analysis / 中国组织工程研究

ABSTRACT

BACKGROUND: With the rapid development of digital orthopaedics, navigational template has been widely used in the field of orthopaedics, but the research status of the technique in China based on bibliometric analysis is never reported. OBJECTIVE: To investigate the application status of navigational template in the orthopaedic field and to explore its tendency and hot spot based on bibliometric analysis, thereby providing reference for the development of digital orthopaedics in China.METHODS: A computer-based retrieval of CBMdisc, CNKI, CSPD, CMCI databases was conducted for articles published before December 1, 2016 using the keywords of navigational template and subject heading orthopaedics and the core orthopaedic journals published in 2016 were searched by manual. The articles were screened according to inclusion and exclusion criteria, and finally were analyzed by bibilometric study.RESULTS AND CONCLUSION: (1) In China, the first paper reporting navigational template was issued in 2008. A total of 199 articles were published in the past 9 years, with more than 10 papers yearly from 2009 to 2014, while there was a rapid increase tendency during 2015 and 2016. (2) The articles were mainly published in the orthopaedic journals and some professional journals closely related to digital orthopaedics, such as biomedical engineering, basic medicine and digital medicine. About 86.9% papers belong to Chinese core journals, including Chinese Journal of Orthopaedic Trauma,Chinese Journal of Orthopaedics, and Chinese Journal of Tissue Engineering Research. (3) There is a 99.5% cooperation rate and 6.15 degree of cooperation. Zhang Yuan-zhi, Ding Huan-wen, Lu Sheng, Chen Yu-bing, Hu Yong,Huang Xuan and Zheng Peng-fei are most productive authors, and core authors contribute to 53.8%, indicating that the group of core authors is being formed. First authors are all from hospitals and universities, mostly from Kunming General Hospital of Chengdu Military Command of PLA, General Hospital of Guangzhou Military Command of PLA, the Affiliated Hospital of Inner Mongolia Medical University and South China University of Technology. The cooperation rate of more than two institutes occupies 54.8%, indicating that the study holds a promising future with the strong support of research institutes in universities. About 59.3% articles are sponsored by funding, the national and provincial foundations accounting for 64.0% in 239 projects, and 57.6% articles were supported by more than two foundations, revealing the high research levels and academic values of this technique. (4) The articles are cited by 763 times; Lu Sheng,Chen Yu-bing, and Zhang Yuan-zhi are the highly cited authors; Kunming General Hospital of Chengdu Military Command of PLA, General Hospital of Guangzhou Military Command of PLA and Nanfang Hospital of Southern Medical University are the highly cited institutes, and Chinese Journal of Orthopaedic Trauma is the highly cited journal. (5) To conclude, based on product design, manufacture and cadaver studies of the navigational template, it has been extensively applied in the spine surgery (especially cervical surgery), orthopaedic traumatology, bone and joint surgery,bone tumor and pediatric orthopaedics, and has obtained satisfactory clinical outcomes in assisting screw placement,osteotomy and precise resection and functional reconstruction. However, there is still a lack of a large-sample,multicenter, and long-term randomized trial.
