The authors have examined the roughness of the heads of four exposed all-metal cemented femoral components of Poldi type using Talysurf 6 device. The results achieved were compared with the roughness of the not yet used head of Poldi femoral component. Both in the exposed and not used heads the Ra factor lower than the value reported in production documentation of the manufacturer. Even in a longterm exposition (17 years) there occurred no changes in the roughness of the metal head of the femoral component. Therefore it is possible in revision surgeries due to aseptic loosening of the acetabular component, to replace only the cup and leave the original stem in place. Key words: THR, femoral component, surface roughness.
