Problems solved by technology

[0002] Proximal tibial fracture is a common fracture, and its incidence rate is about 2.5% of all fractures in the whole body. It is more common in young adults with high-energy trauma and elderly fractures with loose fractures. The purpose of treatment is to restore the function of the shoulder joint to the maximum extent. The healing of conservative treatment is often unsatisfactory, and the previous internal fixation technology is difficult to achieve strong stability so that the shoulder joint can perform early and safe functional exercises, especially for comminuted fractures of the proximal humerus. There are many options and controversies in the treatment

Abstract

The invention relates to an orthopaedic medical instrument tibial bone plate, which includes a ''T'' shaped bone plate body. The bone plate body has an attachment surface contacting the tibia surface, and a bone plate body mounting surface opposite to the attachment surface. The bone plate is provided with mounting through-holes, the surface of the attachment surface is a zirconia ceramic material layer, the surface of the mounting surface is a titanium carbide ceramic material layer, the inner surfaces of the mounting through-holes are chromium oxide ceramic material layers, and the selection of a titanium alloy material and the ''T'' shape of the bone plate endow the bone plate with necessary high strength. The surface treatment process of pickling and passivation on the composition titanium alloy can avoid any surface black spot and other problems, and the obtained surface can be clean and tidy.
