Can titanium alloy replace all the bones in a person's body?
Originally alive and well, the bones will die after being replaced by titanium alloy. The conclusion is: if you don't keep alive, it is easy to replace all the bones of the human body with titanium alloys. The whole body bones will be printed in 3D, and it will be finished after replacement.

At present, joint replacement surgery is really common, but this kind of surgery only replaces a certain part of bones and has little effect on the whole human body. As long as the choice of materials is questioned, it is necessary to choose materials that are not easy to corrode, fall off fragments and cause immune rejection. At present, some operations, such as femoral head replacement and sternal reconstruction, all use ceramics or special alloy materials, which have no effect on human function. After meniscus replacement, even avoiding the original connective tissue meniscus is more wear-resistant and firm.

These can be accomplished by operations such as vascular remodeling, so that the function of the replaced bones will not affect the blood supply and oxygen supply of the surrounding tissues. The bones of the whole human body bear important physiological functions. Flat bones are the main part of blood produced by adults, and some immature cells can differentiate into immune cells, so bones are related to hematopoiesis and immunity. The structure of bones makes muscles easy to attach and blood vessels easy to penetrate, supplying blood to surrounding tissues. If you want to replace the bones of the whole body, you have to give up hematopoietic function and immune function. The longest life cycle of human blood cells is less than half a year, and blood needs to be replaced at any time.

Skeleton is not only a single knowledge to support human functions, but also closely related to many life activities of the human body. At present, it can only be done by replacing human bones, but at the cost of human death, it is useless to say so. However, the development of science is endless, and there are still many things in our life that can't be explained by science for the time being, but it can be said that we humans have been making progress and medical technology is also developing. I believe that in the future, we can have a better medical environment and technical equipment.
