"Prepare a 2.0 Kirschner wire and attach it to the drill."
After Li Zheng finished speaking, he picked up the skin cutting knife again and made an auxiliary incision at the iliac crest of the pelvis to expose the iliac crest.
Li Zheng stretched out his hand.
Lin Xiaomei handed him the electric drill.
Li Zheng first drilled a hole on the iliac crest, leaving one side of the rectangle undrilled.
Reach out again.
Lin Xiaomei handed the hammer and osteotome to Li Zheng.
Li Zheng chiseled open the cortical bone along the three rows of holes, and then chiseled off the cortical bone at the interface between the cortical bone and the cancellous bone, opening the cortical bone like a lid.
Then chisel out a rectangular bone block.
Give the bone to Lin Xiaomei, put it in a sterilized steel bowl, and soak it in saline.
"This piece of bone is beautifully obtained!" Duan Jianhui exclaimed.
Zhou Ming, standing behind Li Zheng, nodded and said, "It's really rare to be able to remove a bone block intact. We remove iliac bones piece by piece."
Li Zheng shook his head and said, "It's not that difficult, it's just that you haven't done it this way before."
Duan Jianhui didn't believe Li Zheng at all. He shook his head and laughed, "Any operation sounds simple when it comes out of your mouth. Don't mislead us!"
Li Zheng smiled, did not respond, and continued to treat the bone defect.
Li was seen using a bone chisel to chisel off some cancellous bone around the rectangular bone cavity and the bottom of the iliac crest to partially fill the cavity, then covering the uncovered cortical bone and fixing it with Kirschner wires.
There is nothing wrong with this operation.
This is how everyone handles it. The cancellous bone has a strong bone-forming ability and the inside will be filled up again after a few months.
After suturing the wound, continue working on the acetabulum.
Li Zheng trimmed the shape of the excised ilium with scissors and implanted it into the bone-defective area of the acetabulum.
"Okay, it's a perfect match!" Duan Jianhui looked at the finger bones that fit perfectly and nodded. The operation was so smooth. So far, there hasn't been any lag, which makes him feel unreal.
Not only did he have this feeling, but all the medical staff present had this feeling.
Especially the instrument technician Jiang Youwei. When he was training, he followed the sales manager to the Provincial People's Hospital in the province to see the professor perform this kind of surgery, but it seemed that none of them could do it as well as Dr. Li.
Li Zheng took the electric drill and Kirschner wire and temporarily fixed the bone block on the acetabulum.
"Acetabular rasp, size 26." Li Zheng said.
"Okay."
Jiang Youwei was already prepared and handed over the electric file.
Li Zheng took it, put the acetabulum rasp in, pressed the switch, and started swinging the connecting rod, stirring and grinding inside the acetabulum.
"Um?"
Both Zhou Ming and Zhang Yong frowned.
In order to ensure the accuracy of the acetabulum angle, after the acetabulum rasp is inserted, it can only be ground along the anatomical direction of the acetabulum. How can the accuracy of the angle be guaranteed if it is stirred randomly?
I thought I was very professional, but now my true colors are exposed.
Zhang Yong sneered and said, "You've worn this acetabulum into a mess!"
Everyone could hear the sarcasm in his words.
Duan Jianhui glanced up at Zhang Yong and Zhou Ming and said with a smile, "You two have never seen such a tough guy before, right? Do you think Doctor Li is messing around?"
Zhang Yong frowned, unsure of what Director Duan meant. But knowing what he had learned, he knew it wasn't wrong. He nodded and said, "Isn't that right? If you grind like that, you might even wear away the transverse acetabular ligament. How can you even determine the abduction and anteversion angle?"
Zhou Ming also nodded. Even when he was studying in the province, he had never seen any expert or professor be so patient.
Duan Jianhui smiled. If he hadn't seen Li Zheng perform surgery yesterday, he would have thought so too. But since he had seen it with his own eyes, he could only say that doctors like him were completely unable to reach the level of a genius's cognition.
"Zhang Yong, I can understand why you think so, because your cognition is confined by your knowledge and you cannot understand things beyond your knowledge. Just watch and you will know whether Li Zheng is messing around or not in a while." Duan Jianhui smiled and said without further explanation, using the results of the operation to speak for himself.
Zhang Yong's face looked very unhappy. Director Duan was saying that he had a narrow vision, but hip replacement surgery had been developed for many years, and he had never heard of such an operation. Could it be that Li Zheng wanted to subvert the existing surgical theory?
dream!
Zhou Ming's face, which was already quite dark, became even darker.
I have the same idea as Zhang Yong, and Director Duan is even getting himself into trouble.
Li Zheng was not affected by them at all.
Continue with the surgery.
The size of the acetabular reamer has been continuously increased.
The swing amplitude of Li Zheng's connecting rod is getting smaller and smaller.
As he was grinding and filing, he observed the stability of the bone graft.
"No shifting, sufficient stability."
After grinding No. 46, Li Zheng wiped the blood with a gauze ball.
"Yes, the subchondral bone bleeding is very even!" Director Duan nodded.
Li Zheng shook his head and said, "It's not enough. There's a bit too much hardened bone."
Director Duan sighed, this was the gap between him and Li Zheng. He thought he was almost there, but Li Zheng had higher goals to reach.
Li Zheng continued to grind with No. 46 for a while, and then repeated the grinding with No. 45.
"Um?"
Zhou Ming and Zhang Yong were dumbfounded again.
What is this operation?
No. 45 has been ground. If you continue to grind it, it will deepen the acetabulum and may even cause the bottom of the acetabulum to be worn through.
Even Zhu Qidong was a little confused. He hadn't seen Li Zheng's surgery yesterday, so he had the same idea, but he was convinced that Li Zheng must have his reasons for doing so.
Duan Jianhui seemed to know what Zhang Yong was thinking. Without even looking up, he smiled and said, "Zhang Yong, when a genius doctor performs surgery, there must be things you don't understand. Otherwise, you'd be just like an ordinary doctor. How can you be called a genius?"
