The object of the research turned out to be an evaluation of the lyophilic properties of different ceramic coatings on the base of aluminum oxide, the character of the porosity and comparison with metal surfaces. Five groups of endoprosthetic groups of heads have been investigated, each series containing six of them. The surface of the heads was studied by means of the МСБ-2 microscope with a lens of a magnification of 100 power. The marginal angle of a fluid drop was measured by means of the method of goniometry. A possibility of absorption of the surface of prosthetic heads was determined by means of the BA-4M balance. When evaluating the results of the research of the nanostructurized ceramic coating of the heads of the unipole implants, a preference of using aluminooxide ceramics with an abolition of the titanium oxide and that of zirconium was detected in order to improve the results of hemiorthroplasty in case of traumas of the hip joint in patients of elderly and senile age.
