Segmental biomechanics after single and multi-level lumbar spine fusion

Brooker, Beau, Pearcy, Mark J., Irvin, Graham D., Adam, Clayton J., Grant, Caroline A., Labrom, Robert D., Askin, Geoffrey N., & Little, J. Paige (2016) Segmental biomechanics after single and multi-level lumbar spine fusion. In 27th Annual Scientific Meeting of the Spine Society of Australia, 8-10 April 2016, Melbourne, Vic.


Clinical studies have reported the incidence of adjacent segment degeneration following posterior lumbar fusion over single or multiple spinal levels. Few existing biomechanical studies investigate the change in motion and stiffness of the fused and adjacent spinal joints following single versus multi-level posterior fusion. This preliminary study showed the segmental motion of spinal joints superior to a single level posterior fusion increased compared to the intact condition and this increase was greater for a two level fusion. In vitro biomechanical studies such as this can help investigate the likelihood of adjacent segment degeneration following spinal instrumented fusion procedures, and future studies will use experimental and computational methods to further understand the lumbar spine mechanics following single and dual level posterior fusion.

Impact and interest:

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
