Surgical aspects, finite element analysis and x-ray correlation of femoral neck changes in the osteoarthritic hip after hip resurfacing surgery

University of Technology, Sydney. Faculty of Science.Background: Hip resurfacing is a logical choice for the treatment of symptomatic osteoarthritis as the degenerative process affects primarily the articular surface. It has been tried previously but failed. Recent improvements in metallurgy, manufacture and engineering have resulted in the development of a new series of implants which appear to be much more successful. Over the last 10 years, they have been used with enthusiasm and increasing popularity. However, over the last two years or so, their popularity has diminished with an awareness of significant complications developing. The complications relate primarily to early fracture, and the possible development of adverse reactions to metal ions. Component position may be implicated in the development of these complications
