New design of pure titanium metal on metal total hip replacement with ion implanted wear resistance surface
Relative movements of the human body parts are enable due to the existence of joints. However, disease and injury codd cause joint disorder.

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. |
