Pre-clinical evaluation of ceramic femoral head resurfacing prostheses using computational models and mechanical testing

Significance of output:

Metal hip resurfacing implants were a successful treatment for young osteoarthritis sufferers, but occasionally elicited metal sensitivity reactions, inflammation and disabling pain. The worst-performing implant system has a 25% failure rate. Resurfacing implants employing biocompatible ceramic materials could offer the same benefits while eliminating sensitivity reactions. Collaborative research with industry (Finsbury Development Ltd.) developed a pre-clinical testing process for this innovative concept. The results comprised the structural verification of a new product, enabling its CE-mark approval for clinical use. The developed test process contributed to the state-of-the-art where existing BS/ISO tests are applicable only to traditional prostheses. (Industrial Referee: mike.tuke@matortho.co.uk)
