The operation continued, with no sign of being disturbed by their 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 focus is a powerful thing.
Looking at the people outside the operating table, Cao Yong and Tao Zhijie were not disturbed by the crowd behind them, and their attention was focused on the operation without distraction. Among the orthopedic doctors behind them, only one was talking to Ren Chongda. If the others didn't hear them talking, they were all concentrating on the operation.
Thinking about the shocking result brought about by the previous operation, everyone knew that this operation would be extremely wonderful and might even be recorded as a classic case in orthopedics.
Removing the bone is the key to completing the first half of the operation, and soon we will reach the key to the second half. Removing a piece of bone is equivalent to breaking the spine, which is like a bridge that has broken its deck and piers and can no longer be used. Now the doctor has to find a way to fill in the defect, and he took out the materials that Xie and his friends had seen in Chang Jiawei's office the day before yesterday.
The human body is like a machine. If it is broken and any original parts are missing, it can only be replaced by other parts. The artificial vertebrae that doctors have tried every means to create are external parts that need to be considered. If possible, they can find similar parts of the body. For example, when making teeth, even if the teeth are missing, doctors will always try to preserve the roots and put on crowns. Like humans and machines, the original ones are the best. Using other materials as a substitute is a last resort.
We talked about several artificial vertebrae that day. Today, the doctor chose the titanium cage commonly used in clinical practice as usual. I mentioned it briefly last time. Titanium cage may be the simplest equipment, but the most advanced one is difficult to adjust by itself. It is better to rely on the doctor's brain and hand skills to adjust it. The length of the titanium cage can be cut by the doctor according to the patient's needs. It can be as long as desired. The determination of this length depends on the doctor's brain again.
Doctors have been measuring instruments before surgery based on CT scans and other imaging data combined with clinical examinations, and they probably have a rough idea of the length during surgery. However, the length can only be estimated first and then fine-tuned during surgery.
The length of the titanium cage is not only determined by the length of the defect after the diseased bone is removed, but the doctor also needs to consider other factors. When you take out the titanium cage and see that it is hollow inside, you will understand that it is much more than just its appearance. The reason why it is not made solid is because the hollow part needs to be filled with bone.

The gaps in the human body are not filled in the way that outsiders imagine, because the human body is made up of living cells, not dead matter. One of the most important characteristics of a living organism is that it can continuously metabolize, which is called tissue cell regeneration in professional terms, or growth in a more popular sense.
Doctors need to effectively use this vitality to help the human body recover health, rather than mechanically repairing dead objects. A reference may be botany, where seeds are sprinkled into the soil to grow. This principle can be called bone fusion in orthopedics. The transplanted bone tissue is placed in the defective bone environment for filling, allowing its cells to grow naturally and then fuse with the original bone tissue. Similarly, bone blocks are filled into the titanium cage to allow bone cells to grow again and become a new fusion with the original bone.
Don't think that bones are hard and not soft and are dead.
