The WA branch of the ACA will be meeting for a guest lecture from Moreica Pabbruwe (Centre for Implant Technology and Retrieval Analysis) on corrosion in medical devices.
Joint replacement surgery represents one of the most successful medical advances of the 20th century with 49,764 hip replacement surgeries and 65,266 knee replacements performed in Australia in 2018-2019. This number is expected to rise 276 per cent by 2030 costing Australia’s health care system over $5 billion, with the main drivers of growth being obesity and our ageing population.
Implant retrieval analysis is an effective tool used to evaluate implant-patient interactions to identify the modes and mechanisms that lead to the success or failure of medical devices, including surgical and patient factors that contribute to implant failure. The Centre for Implant Technology and Retrieval Analysis (CITRA) has been providing this service to hospitals in Western Australia for more than 40 years. Clinical data is combined with scientific investigations to determine the factors contributing to implant failure, aiming to improve the clinical delivery of surgical services and the outcome for the patient.
Early retrieval studies demonstrated galvanic corrosion due to mixed metal alloys and a correlation between corrosion and biological reactions such as allergic reaction to metallic elements in the implants. In this presentation, Moreica will provide a summary of retrieval studies evaluating corrosion in failed hip and knee components.

Materials Science Engineer, Universidad Simon Bolivar, Caracas (Venezuela)
PhD, University of New South Wales, Sydney (Australia)
Moreica currently works as a Biomedical Engineer at the centre for implant technology and retrieval analysis (CITRA) based at Royal Perth Hospital. Where they offer a state-wide service evaluating retrieved and new medical devices; using analytical techniques to understand the factors that affects the clinical performance of implants. The overarching goal of this work is to gain information that can be used in the development of better biomaterials, to create implants with improved properties.
