MRI reveals individual level deformities in the growing scoliotic spine that clinically are masked by the Cobb angle

Keenan, Bethany E., Izatt, Maree T., Askin, Geoffrey N., Labrom, Robert D., Bennett, Damon Dmitry, Pearcy, Mark J., & Adam, Clayton J. (2015) MRI reveals individual level deformities in the growing scoliotic spine that clinically are masked by the Cobb angle. In 25th Annual Scientific Meeting of the Spine Society of Australia, 10-12 April 2014, Brisbane, Qld.


Clinically, the Cobb angle method measures the overall scoliotic curve in the coronal plane but does not measure individual vertebra and disc wedging. The contributions of the vertebrae and discs in the growing scoliotic spine were measured using sequential MRI scans to investigate coronal plane deformity progression with growth. Sequential MRI data showed complex patterns of deformity progression. Changes to the wedging of individual vertebrae and discs may occur in patients who have no increase in overall Cobb angle measure; the Cobb method alone may be insufficient to capture the complex mechanisms of deformity progression.

Search Google Scholar™

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.
