Bone tissue formation around the pins made of medical steel (1st group, n=9), titanium alloy BT6 with modified by chemical and thermal treatment surface (2nd group, n=8), titanium alloy BT6 with calcium phosphate and 1% germanium coating sprayed using microarc oxidation technique (3rd group, n=5) and of the same alloy with calcium phosphate and 5% germanium coating (4th group, n=7) was studied on 28 mongrel cats. The pins were inserted into the proximal femur. In 3 months (after euthanasia) roenthenography, CT with densitometry, biomechanical testing (to determine the strength of implant-bone adhesion) and histologic examinations were performed. It is shown that osteointegration processes were the most marked in the animals from 3rd and 4th groups.
