Crack initiation processes in acrylic bone cement
Significance of output:
Hip and knee implants are fixed into bone using bone cement. Loosening of hip and knee implants is the most prevalent cause of failure, costing the NHS ~£45 million annually (England and Wales National Joint Register 2011). This research employed non-destructive techniques to demonstrate the origin of cracks in bone cement at an unprecedented scale. Consultant orthopaedic surgeon Jeremy Latham states: “The methodologies developed are central to the activities of the implant retrieval centre at Southampton as they inform on how cemented implants are loosening, and inform on the development of new cement formulations that are more robust against loosening.
