Background
Recent efforts to improve patient outcomes after amputation prompted the integration of the novel techniques Targeted Muscle Innervation (TMR) and Regenerative Peripheral Nerve Interface (RPNI) into conventional amputation surgery. TMR and RPNI become one of the hot topics in Plastic Surgery. In this study, we analyzed the publication and authorship trends of TMR/RPNI bibliometrically.
Materials and Methods
A systematic search of the PubMed/Medline database was conducted, which identified 1030 articles (868 TMR and 162 RPNI). The Journal Citation Reports - Web of Science Group – Clarivate tool, gender API, and Researchgate were utilized to determine the journal Impact Factors, author genders, and the number of citations, respectively.
Results
One hundred seventy-four articles were included in the final analysis. As TMR was introduced to the field a decade earlier (2004 vs 2014), more than 2/3rd of the articles was on TMR. These articles were published in various journals, mainly with a medium Impact Factor (IF). The journals with the highest IFs were Lancet (202.7) for the TMR; Annals of Surgery (13.78) for the RPNI studies. The articles with the highest citations had 838 (TMR) and 98 (RPNI) citations. Gender disparity was observed in the first (TMR 68.8%; RPNI 75%) and senior authorship (86.1%; RPNI 76.9%).
Conclusion
The first few years of the TMR/RPNI research are characterized by publications exclusively by the original group describing the technique. The introduction of the RPNI overlapped with the start of the second TMR period, in which the first publications by the other USA and international institutions were noted.
