No one knows whether these slight differences will have any effect. After all, no doctor had cared so much before.
Today is different. There is an unusual person who has a single-minded mind.
People in the orthopedics department may be able to see some clues before people in other departments.
When it comes to driving screws into the pedicle, orthopedic surgeons are most afraid of hitting the nerve root. The EMG electromyography monitored during surgery is precisely to help orthopedic surgeons monitor this. Once there is a violently undulating waveform on the electromyogram, which symbolizes explosive electrical activity, it must be 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 ups and downs. The reason is that it is basically impossible for doctors to hit the location very accurately by visual estimation. Furthermore, if the bone is hard, it is not possible to determine the most suitable structural position for the nail to enter when driving. If it is difficult during the period, increasing the strength will produce vibration waves that 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 and there is no problem.
Now this group of orthopedic surgeons are looking at the electromyogram: Good guys, this is a flat graph that I have never seen before. There is almost no fluctuation. The slightest fluctuation can be ignored and the duration is super short. This shows that the nail landed on the bone at just the right position, 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, all the screws were driven in, so fast that he felt his hands shaking. My hands were shaking not from fear, but from excitement.
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 could tell that the surgeon was in the right position without the professional ability of an orthopedic surgeon.
Chang Jiawei did not forget to let Xie try his hand on the last screw.
Xie Wanying couldn't hide her joy as she could try out the strenuous work of orthopedic surgery.
A group of people looked at her, their eyebrows flying like a skylark singing loudly, and their hearts seemed to tremble, as if they were facing a scene in a movie that was about to reach the climax after the ups and downs.
Everyone could only think that Chang Jiawei, a playboy, asked her to beat him, maybe because he wanted to please a girl without changing his nature, or because he really wanted to see if she could be an armchair strategist besides having great theoretical knowledge. Whether technology can keep up with her super-computing brain is questionable. Orthopedics, unlike other departments, requires higher physical skills for girls. Regarding the latter, everyone was equally interested in seeing what happened.
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: Is this the case—?
Does she often tighten screws at home? Is her home a factory?
She is good at turning screws. When I was a kid, I played with my dad repairing cars, and we used to pull all kinds of screws with our little hands. The thread of the screw is particular. Growing up, she could often hear her father and other colleagues discussing the uses and properties of various screws at home when they were repairing cars.
