Physical and Chemical Properties of the Implant Used for Double Pelvic Osteotomy/Triple Pelvic Osteotomy Procedure in Dogs

This study aimed to determine the physical and chemical properties of a titanium alloy implant used to treat hip dysplasia in dogs. The scope of the study included examination of: surface morphology using light microscopy, optical profilometry, scanning electron microscopy, structure, hardness and hardness profile of the surface layer, adhesion of the surface layer, pitting corrosion resistance, wettability, chemical composition of the surface and passive layer using EDS and XPS. On the basis of the conducted tests, the quality of the implant was found to be satisfactory. The implant is made of biphasic Ti6Al4V alloy, it is characterized by a homogeneous surface topography, the hydrophilic surface layer is characterized by good adhesion to the substrate, the passive layer, formed on the substrate strengthened by vibratory treatment, consists mainly of titanium oxides and protects the implant from pitting corrosion. The specified set of physical and chemical properties of the implant indicates that it should be characterized by biocompatibility in the environment of the dog’s body.
