How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
Silicon nitride (Si3N4) is a promising biomaterial, currently used in spinal fusion implants. Such implants should result in high vertebral union rates without major complications. However, pseudarthrosis remains an important complication that could lead to a need for implant replacement. Making silicon nitride implants more bioactive could lead to...
The growing elderly and more active population puts higher demands on implants, which need to last longer and withstand more severe loading conditions. In the spine, mechanical resistance and biocompatibility are especially important due to the vicinity of sensitive tissues such as the spinal cord and nerves. NU-SPINE aims to deliver novel material compositions with a higher degree of biocompatibility as well as novel implant designs adapted to the local loading situation.
