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

Abstract

Objective: 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.

Methods: 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).

Results: 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.

Conclusion: 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.
