Biocomposition coats for external transosseous osteosynthesis

Abstract

Aim of the study: to develop and substantiate in experimental and morphologic way possibilities for use of biocomposition plasma-sprayed coats of rods and wires for devices of external fixation on the basis of hydroxyapatite.
Object of the study: mongrel dogs of the same weight and age, which were mounted coated rods and wires in different parts of limb skeletal bones. Periods of observation were 7, 15, 45 and 60 days after surgery. Bone tissue, adjacent to the implants, was studied. The main results of the study gave the possibility to develop and substantiate the coat on the basis of powdered titanium, corundum and hydroxyapatite, having limited osteointegration with bone tissue. Clinical use of the proposed technology allowed to decrease number of specific complications up to 8%.
