Paper Abstract

The purpose of the paper is to describe the measurement of shape of ceramic insert of coxal implant. In contrast to polyethylene inserts, the ceramic inserts suffer very low wear during its usage, just about micrometers per year. It is necessary to use coherence optical methods to sensitive enough to measure such small deformation. The contribution describes principles of interferometry, the construction of experimental setup using Fizeau interferometer and discusses the qualitative results of measurement of low-weared ceramic inserts of hip endoprothesis. These results will be used to compare the wear of polyethylene and ceramic endoprothesis inserts and to create a statistic file of ceramic inserts wear. This statistic file will be used to compare the wear of each ceramic insert with the age, gender, condition, way of life and etc. of patients, who were using these implants.
