Summary
Publications on cervical sagittal alignment have surged dramatically, increasing tenfold every 15 years. This trend highlights growing interest in personalized spine surgery and motion preservation techniques.
Area of Science:
- Spine Surgery
- Bibliometric Analysis
- Cervical Spine Research
Background:
- Spinal alignment is crucial in spine deformity surgery, with a growing focus beyond the thoracolumbar region to the cervical spine.
- Global balance has become a key consideration in surgical outcomes.
- Cervical sagittal alignment is an emerging area of significant research interest.
Purpose of the Study:
- To analyze bibliometric trends in cervical sagittal alignment research over time.
- To quantify the growth in publications related to cervical sagittal alignment.
- To identify key areas of focus within this research domain.
Main Methods:
- Bibliographic data sourced from Web of Science, PubMed, and Scopus.
- Keyword searches included "cervical" and "sagittal alignment" variations.
- Bibliometric analysis using Excel and network visualization with VosViewer™.
Main Results:
- A tenfold increase in publications every 15 years since 1994, significantly outpacing general spine publication growth.
- Publication rates accelerated, with over 50% year-over-year increases in 2012-2013 and 2016-2017.
- Recent research emphasizes deformity, laminectomy, and motion preservation.
Conclusions:
- Cervical sagittal alignment research has experienced rapid, disproportionate growth in the last decade.
- This growth likely reflects increased interest in personalized surgical approaches.
- The findings underscore the importance of spinal alignment across the entire spine.
