This study gives the definition of the tribology system of hip joint prosthesis. The aim of the study was to examine the nature of damages occurring on the joint surfaces. The analysis was performed using a Ring's total prosthesis. Out of two terminal types (kinds) of motion, torsional swinging motion of the acetabular prosthetic component was examined in relation to the femoral component. The testing device was adapted to suit this special purpose: a four-part mechanism was added for real motion simulation. Changes of roughness and friction moment in time were measured for the input parameters of loading, velocity flow and roughness. The obtained values show that real radius of friction does not correspond to the theoretical one and that out of overall frictional surface only a small portion is realized, which may account for the damage of the frictional surfaces and loosening and migration of the hip prosthesis.
