CT-semiotics of tibial reparative processes for intramedullary osteosynthesis using the implants coated with titanium and hafnium nitrides experimentally

Abstract

Purpose. Comparative studying the local state of bone tissue in the regeneration zone for fixation of tibial fragments using wires of 12X18H9T steel with nanotech coating experimentally. Materials and Methods. Biological properties of nanocoating based on superhard compounds of titanium and hafnium nitrides studied experimentally in 40 mongrel rabbits. Results. The positive effect on the formation of regenerated bone observed in the animals with the coating studied. The processes of bone tissue reorganization occurred earlier unlike the comparison group determined by higher cortical density. Conclusion. The use of implants with the coating of titanium and hafnium nitrides having high strength, thermal and chemical stability accompanied by forming the cortical plate with higher density values in osteoclasis zone.
