Can Titanium Completely Replace Bones?


Not now, maybe in the future

First of all, the current level of technology can only partially replace the own bones with artificial bones. If the whole body is replaced according to the subject, every bone of the human body will have a different size and need to be individually customized. The difficulty and production cost of the operation are immeasurable. Secondly, the hematopoietic function of bones cannot be simulated by titanium alloys. The erythropoietin EPO secreted by the kidneys can promote the differentiation and growth of bone marrow hematopoietic stem cells, but titanium alloys do not have this function, unless you can fully believe that your doctor is in your body. The whole body bone marrow transplantation experiment can be very successful. However, you are very lucky that every bone is successfully transplanted into your body. Next is more complicated connective tissue splicing. If it fails, you will be cold, the wounds on your body will not heal at all, and various viruses will invade your body. However, Goddess of Luck once again took care of the subject. After a long period of various repairs, all the operations were completed successfully, and the basic maintenance in the later period was also an area that had never been involved. The maintenance was difficult. It can be imagined. With a little carelessness, the skeleton of the subject in the cremation furnace is shining brightly.


Let’s take a look at the concept given by Baidu Encyclopedia: Artificial bone is a new type of inorganic non-metallic material with biological functions. It is similar to the structure of human bone and natural teeth. Artificial bone can rely on supplementing certain ions from human body fluids. The formation of new bone can cause decomposition, absorption, precipitation and other reactions at the joint interface of bones to achieve firm bone bonding. Artificial bone implantation in the human body requires Ca2+ and PO4 3- ions in the human body to form new bone. Titanium alloy has very good biocompatibility with the human body and is non-toxic, corrosion-resistant, and heat-resistant. These characteristics make titanium alloy a raw material for artificial bone. In the bone injury, fix it with a titanium plate and a titanium screw. After a few months, the bone will grow on the titanium plate and the screw thread. The new muscles are wrapped in titanium plates. This "titanium bone" is like real bones, and even titanium artificial bones can be used instead of human bones to treat fractures. At present, partial replacement of artificial bone is very successful. Therefore, the foundation of the tall building has been laid. How many pioneers must there be?
