A biomechanical analysis of growing rods used in the management of early onset scoliosis using a robotic testing facility

Irvin, Graham D., Brooker, Beau, Askin, Geoffrey N., Labrom, Robert D., Pearcy, Mark J., Grant, Caroline A., & Adam, Clayton J. (2016) A biomechanical analysis of growing rods used in the management of early onset scoliosis using a robotic testing facility. In 27th Annual Scientific Meeting of the Spine Society of Australia, 8-10 April 2016, Melbourne, Vic. (Unpublished)


This investigation tested semi-constrained growing rods and rigid fusion rods used in the management of scoliosis and examined how instrumentation with these devices affected the biomechanical properties of the spine. This study shows that semi-constrained growing rods allow a greater range of motion than rigid rods in our porcine model through instrumented levels. These findings support the use of semi-constrained growing rods, as this construct allows a range of motion that is closer to that found in an un-instrumented spine while correcting deformity and allowing for continued growth.

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.
