Nondestructive Evaluation of Bone Cement and Bone Cement/Metal Interface Failure
The majority of primary and revision hip replacements in the UK use bone cement for fixation. Failure of the bone cement and implant/cement interface are the main causes of implant loosening. This paper shows that the damage evolves via a change in stiffness at the cement metal interface followed by the sudden formation of a debond at the interface. It is a collaboration between UCL and Southampton University with industrial support from DePuy (Andrew Taylor, Finsbury Orthopaedics, UK) and Action Medical Research. The understanding of the mechanisms of failure will be used in developing the future generation of femoral components.
