Abstract

Damage in the joints may entail deterioration of life quality to a great extent. More than seven hundred thousand big joint (hip-, knee, etc.) prostheses are implanted annually in the world to improve the quality of life, and this number in Hungary amounts to approximately ten thousand. Currently the lifetime of prostheses is approximately 10 years [1]. Unfortunately, prostheses are often lost beyond this period, thus replacement is needed. In this paper the geometric construction, modelling and Finite Element Analysis of the hip-joint prostheses will be introduced.
