Abstract

Relative movements of the human body parts are enable due to the existence of joints. However, disease and injury codd cause joint disorder. Nowadays, joint replacement is a widely accepted treatment for damaged joint. In Malaysia, hip joint or knee joint replacements, either as total or partial, have become a standard procedure in many hospitals. Sultanah Aminah hospital for example, conducts 4 5 joint replacement surgeries every week. A typical art&cial joint consists of two different materials which have self lubricating bearing behaviour such as metal and polymer. A well perform joint must fulfil bio mechanics aspects of mobility and stability, as well as bio compatibility aspects. Despite of the smooth mobility, the main problem by metal-polymer bearing is the wear which occur in the surface contact, because friction moment will create small particles or debris which can accumulate in the surrounding human tissue and cause various problems. Many studies reported that metal-polymer pair contact is satisfactory for short term only. Therefore, a hard material couple such as metalmetal which provides better tribologicral propertie is considered high potential. The current available metal-metal joint is made from Titanium alloy Ti-6A1-4V, but the toxic presence of A1 and V ions in this alloy has been a serious issue of concern. The aim of this study is to obtain the Iong lifetime of the hip joint implant without significant negative effect of wear debris.
