The changing paradigm of spine motion preservation: A bibliometric analysis of dynamic posterior stabilization

Traditional rigid posterior lumbar fusion frequently induces adjacent segment disease due to non-physiological stress concentrations. While dynamic and semi-rigid posterior stabilization systems were introduced to preserve segmental motion and share biomechanical loads, the expanding global literature remains fragmented. This study aims to perform a comprehensive bibliometric and computational science mapping analysis to decode the global intellectual architecture, collaborative networks, and shifting research frontiers of dynamic posterior spinal stabilization from 1999 to June 2026.

Global literature metadata regarding dynamic posterior stabilization was systematically retrieved from the PubMed/MEDLINE database covering a 27-year timespan (1999-June 2026). Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, an initial search yielded 375 records. A rigorous multi-step filtration and screening protocol was executed to remove ineligible and off-topic documents, resulting in a final, highly targeted dataset of 332 peer-reviewed articles. Quantitative bibliometric processing, social network mapping, and strategic thematic clustering were executed utilizing the open-source Bibliometrix package in R Studio (v4.3.2).

The field exhibits a sustained annual compounding growth rate of 5.27%, with publication volumes peaking sharply in 2010 and 2016. Scholarly output is heavily clustered within elite spinal literature, led by SPINE (n=29) and the European Spine Journal (n=27). Geographically and institutionally, a pioneer Turkish research cluster led by Ozer AF, Oktenoglu T, and Sasani M maintains a high publication volume and prominent research influence. Social network tracking identified a robust transatlantic collaboration axis connecting Turkish pioneers directly to elite North American institutions, alongside a substantial contemporary East Asian research surge. Chronological timeline (Trend Topics) and strategic thematic mapping revealed a profound paradigm shift: The research frontier has matured from basic hardware safety and clinical cohort validation toward advanced engineering-driven computational optimization, heavily dominated by finite element analysis evaluating load-sharing configurations and prosthesis failure modalities. Conversely, complex posterior element configurations like total facet arthroplasty have drifted into declining quadrants.

Dynamic posterior stabilization remains a highly active research domain within mainstream spine surgery. The global scientific landscape has successfully evolved into a sophisticated bioengineering-driven discipline centered on computational simulation and sagittal alignment customization. Integrating advanced finite element modeling with long-term prospective multicenter registries will dictate the development of next-generation motion-preserving spinal implants.
