Abstract

The initial solid fixation of an uncemented acetabular component affects the amount of bone ingrowth. We had several problems with broken screws in cases of acetabular revision. In recent years, the development of uncemented components without screws has attempted to improve these problems. We started to use "press-fit"-type acetabular shells in November 1996. Our thirty cases undergoing 2 mm under-reaming show good initial stability. The aim of our biomechanical study was to assess the most suitable degree of under-reaming of the bony acetabulum for the implantation of an uncemented hemispherical porous coated component.
