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.
