    Total hip arthroplasty significantly improves the quality of life in majority of patients with osteoarthritis. However, prosthetic wear is a problem. The paper gives principles of three methods suggested for construction of a device for the non-contact prosthetic wear measurement. The second aim of the paper is to describe the way how to evaluate the precision and repeatability of these methods for a given purpose.

    Totální náhrada kyčle významně zlepšuje kvalitu života pacientů, trpících osteoartrózou. Závažným problémem těchto implantátů je otěr kloubních povrchů. Článek vysvětluje principy tří metod použitelných pro konstrukci zařízení pro měření celkového otěru extrahovaných implantátů. Dalším cílem článku je popis postupu ověření vhodnosti těchto metod pro daný účel.

    This paper deals with an evaluation of the surface roughness quality created by abrasive water jet and by CO2 laser, in terms of influence of the selected technological parameters on the final quality of machined surfaces. The main objective of these experimental studies was to consider the use of both technologies for cutting of difficult to cut materials. Experiments presented in the paper were carried out on titanium ASTM B265-99 samples. The machined surfaces of samples were measured by an optical profilometer. Subsequently, selected topographical characteristics were studied. The obtained data were used for comparison of surface roughness parameters Ra in different depths. Based on achieved results the comparison of both technologies was made.
