The effect of soft tissue properties on overall biomechanical response of a human lumbar motion segment: A preliminary finite element study
Cunningham, Helen, Little, J. Paige, Pearcy, Mark J., & Adam, Clayton J. (2007) The effect of soft tissue properties on overall biomechanical response of a human lumbar motion segment: A preliminary finite element study. In The Adelaide Centre for Spinal Research - Spinal Research Symposium V, 28-30 August 2007, Adelaide, Australia.
Finite element (FE) modelling is a popular numerical method used to study the biomechanics of the spine. Existing FE models have been used to investigate the effects of tissue degeneration, fixation implants and vertebral fractures. However, a wide range of geometric and material properties have been used to represent the soft tissues of the spne, and there is no consensus on the best approach for soft tissue modelling, or the relative importance of various soft tissues in governing the biomechanics of the motion segments. This study investigates the relative effect of soft tissue properties on the overall response of a human spinal motion segment using an osseo-ligamentous FE model of the Visible Man L3-L4 intervertebral joint. The results from this study demonstrate that some soft tissue structures are more critical than others in determining the characteristic behaviour of the spine. Correct representation of the mechanical properties of both the capsular ligament and anular fibres is most important in generating realistic FE models of the lumbar spine to predict motion segment biomechanics.

Citation countsare sourced monthly fromand 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 theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
