CASE STUDY
Ex vivo Biomechanical Testing of Nucleus Replacement Devices in Bovine Specimens
#BespokeTesting #MedTech
The aim of this project was to provide an experimental analysis of how different hydrogel formulations affected the biomechanics of a bovine functional spinal unit when implanted as a nucleus replacement device.
​
We designed and conducted bespoke testing protocols to investigate the biomechanics of intact, de-nucleated, and implanted bovine specimens. These comprised of uniaxial compression tests and the development of an integrated measuring device to create pressure profiles across the disc space.
​
Our customised data-analysis scripts allowed for the processing of high volumes of data and visualisation of the results for the clients to easily compare hydrogel formulations.
