No one knows whether these slight differences will have any effect. After all, no doctor has cared about it like this before.
Today is different, there is an unusual person with a single mind who starts to care.
People in the orthopedics department may be able to spot some clues before people in other departments.
When it comes to inserting screws into the vertebral pedicle, orthopedic surgeons are most afraid of hitting the nerve root. The EMG electromyogram monitored during the operation is precisely to help the orthopedic surgeon monitor this. Once there are violent fluctuations in the electromyogram
The waveform diagram symbolizes explosive electrical activity, which must mean that the nerve root has been mechanically stimulated. The worse result is that the vertebral pedicle is ruptured.
Generally, when an orthopedic surgeon performs an injection, there will be some undulations. The reason is that the doctor estimates with the naked eye that it is almost impossible to hit the location very accurately. No matter how hard the bone is, he cannot be sure that the most suitable nail will be hit during the injection.
When entering the structural position, if you increase the strength during the period, it will produce vibration waves that will affect the nerve roots. For this reason, during the pedicle screw fixation process, a wave of graphic fluctuations is normal, as long as it is not too big, there is no problem.
Now this group of orthopedic surgeons are looking at the electromyogram: Good guys, this is a flat pattern that I have never seen before. There is almost no fluctuation. The slight fluctuation is negligible and the duration is super short. It means that the nail falls on the bone.
The position is just right, hitting the most suitable point on the bone structure. So just like driving a nail on a cement wall, hitting that precise structural position, click click click, the process must be extremely smooth.
Chang Jiawei was very relaxed. It seemed that after a few clicks, the screws were all driven in. It was so fast that he felt that his hands were shaking. It was not that he was afraid, but that he was excited.
Playing smoothly is like fighting monsters in a game, your blood is boiling and your energy is high.
When people from other departments looked at this situation, they didn't have the professional ability of an orthopedic surgeon to see that the surgeon was in the right position.
Gu JiaoFor the last screw, Chang Jiawei did not forget to let classmate Xie try it.
Xie Wanying could not hide her joy as she could try out the strenuous work of orthopedic surgery.
A group of people watched her with eyebrows flying like a lark, and their hearts seemed to tremble, as if they were facing a scene in a movie that was about to reach its climax after ups and downs.
Everyone could only think that Chang Jiawei, a playboy, asked her to beat him because he wanted to keep his nature and please a girl, or he really wanted to see if she could be an armchair strategist besides having great theoretical knowledge.
It is doubtful whether the technology can keep up with her super-computing brain. Orthopedics is not like other departments, which requires girls to have higher physical skills. Regarding the latter, everyone is equally interested in seeing what happens.
With the tool in hand, Xie Wanying grabbed the flat-shaped handle of the wrench, pushed in the locking screw, put it into the bone that the teacher had previously drilled, and started to tighten.
A group of people first observed that she was very skilled in screw-twisting gestures and seemed to be unusually familiar with the performance of screws: What is this situation—?
Does she often tighten screws at home? Is her home a factory?
She is good at tightening screws. When she was a child, she and her father would play car repairs, and they would often use their hands to pull various screws. The threads of the screws were particular. Growing up, she could often hear her father and other people talking at home.
When colleagues were discussing car repairs, they mentioned the uses and performance of various screws.
