The operation continued without any sign of being disturbed by their few words of conversation. Dr. Liu was frightened. Except for Dr. Liu, the chief surgeon and the second assistant did not seem to realize that there were outsiders.
This kind of concentration is a very powerful thing.
Look again, people outside the operating table, such as Cao Yong and Tao Zhijie, were not disturbed by the crowd behind them, and their attention was focused on the operation. Only one of the orthopedic surgeons behind was talking to Ren Chongda. If the others did not hear them,
, all focused on the operation.
Thinking about the shocking results of the previous surgery, everyone knew that this operation would be extremely exciting and might even be recorded as a classic orthopedic case.
Removing the bone is the focus of the first half of the operation, and the focus of the second half of the operation will soon be reached. Removing a piece of bone is equivalent to breaking the spine. This phenomenon is like a broken bridge deck and piers that can no longer be used. Now the doctor wants to
The idea of filling in the missing parts was to take out the materials Xie and his colleagues visited in Chang Jiawei's office the day before yesterday.
The human body is like a machine. If a piece of original part breaks down and is missing, you can only find another one to replace it. The artificial vertebra that the doctor tried to create is an external part and needs to be considered. If possible, look for similar internal parts. For example, if you have to do dental work, even if
When a tooth is too missing, the doctor will always try to preserve the root of the tooth and put a crown on it. It is best if the person and machine are original, and replacing it with other materials is a last resort.
We talked about several artificial vertebrae that day, and today the doctor chose the titanium cage that is commonly used in clinical practice as usual. As mentioned last time, the titanium cage may be the simplest device, but the most advanced ones are difficult to self-adjust. It is better to rely on the doctor's brain.
The length of the titanium cage can be adjusted by using hand techniques. The doctor can cut the length of the titanium cage according to the patient's needs. The length can be determined by the doctor's brain again.
Doctors have been doing the work of measuring equipment based on CT scans and other imaging data combined with clinical examinations before the operation. During the operation, the doctor probably has a picture of this in mind. However, the length must only be estimated first.
, and then fine-tune it during the operation.
The length of the titanium cage is not only based on the length of the defect after removing the diseased bone, the doctor needs to consider other factors. When you take out the titanium cage and see that it is hollow inside, you will understand that there is much more to it than what it looks like.
Simple. The reason why it is not made solid is because the hollow part needs to be filled with bones.
The filling of the gaps in the human body is not like what outsiders imagine. The human body is made up of living cells, not dead objects. One of the most important characteristics of a living body is that it can continue life metabolism. The technical term is tissue cell regeneration, which is popularly known as tissue cell regeneration.
Click on a word and say it is long.
Doctors need to effectively utilize this vitality of life to help the human body regain health, rather than mechanically repairing dead things. A good reference may be botany, where seeds are sprinkled into the soil and allowed to grow. This principle can be used in orthopedics.
It is called bone fusion. The transplanted bone tissue is placed in the defective bone environment to fill it, allowing its cells to naturally regenerate and then fuse with the original bone tissue. In the same way, bone blocks are installed in the titanium cage.
Filling, allowing bone cells to regenerate and form a new fusion with the original bone.
Don’t think that a bone is a dead object because it is hard but not soft.
