Disclosed is an orthopaedic medical instrument tibia bone fracture plate. The orthopaedic medical instrument tibia bone fracture plate comprises a bone fracture plate body, the bone fracture plate body is T-shaped, the bone fracture plate body is provided with an attachment surface 1 in contact with the surface of a tibia and a bone fracture plate body installation surface 2 opposite to the attachment surface 1, the bone fracture plate is provided with installation through holes 3, the surface of the attachment surface 1 is a zirconium oxide system ceramic material layer, the surface of the installation surface 2 is a titanium carbide system ceramic material layer, and the inner surfaces of the installation through holes 3 are chrome oxide system ceramic material layers. The orthopaedic medical instrument tibia bone fracture plate has the following advantages: 1, through selection of a titanium alloy material and the T-shaped structure of the bone fracture plate, the bone fracture plate is enabled to have necessary high strength; and 2, surface processing technologies such as acidwashing and passivation are preformed on a titanium alloy of such components so that the problems of block spots on any surfaces and the like are avoided, and an obtained surface is neat.
