Science Today: Computer-aided design gets hip - Researchers at Dublin City University are trying to develop a better artificial hip joint, one that lasts longer and causes fewer problems, writes Dick Ahlstrom.

(From The Irish Times)

Computer design systems, digitised models of human joints and 'fuzzy logic' are all being pressed into service to build a better hip joint. A Dublin City University team is using the latest technology in an important new research area, 'medical engineering'.

'Research in computer aided design has gone beyond the building of solid models, it now goes on to model how the component will perform when in service,' explains Dr Bryan MacDonald, a lecturer in DCU's School of Mechanical and Manufacturing Engineering. He heads a research group which uses advanced modelling to assess the performance of replacement joints and other engineering …
