Director Duan and Zhou Ming both looked at Zhang Yong in surprise.
Zhang Yong didn't care about the opinions of the people around him at all. He only had Li Zheng in his eyes.
Li Zheng used curved pliers to tap the radial styloid process of Zhu Qidong's right wrist. There is an acupuncture point here called Lieque, which will feel very painful when tapped.
"Hiss, ah, Brother Zheng, why are you hitting me?" Zhu Qidong was startled.
The others also came to their senses.
Li Zheng said in a deep voice: "Don't be distracted during the operation, concentrate!"
Zhu Qidong quickly adjusted the position of his legs to make it easier for Li Zheng to operate.
"Hehe, the main reason is that your operation, Brother Zheng, is so magical that people fall into it unknowingly." Zhu Qidong was not unhappy about being beaten, but very happy. This shows that Li Zheng is not so unfamiliar with him and treats him as his own!
The operation continues.
After all the bones of the left lower leg away from the broken end were fixed, Li Zheng began to fix the proximal stump.
Live broadcast room next door.
All the doctors felt their scalps tingling.
They saw Li Zheng using almost abnormal speed and accuracy to drive Kirschner wires into the tibia, fixing the tiny bones one by one.
This completely overturned their understanding of Kirschner wire surgery.
Especially several orthopedic surgeons.
They previously thought that Li Zheng was arrogant and presumptuous when he said he would fix the external fixator, but now it seems that Li Zheng is not arrogant at all, but is trying to give face to Director Duan. If he had said from the beginning that he would do it, that would have been the real arrogance.
"No wonder Dr. Li said the limb could be saved. By fixing the fracture in this way, he preserved the limb's length as much as possible, laying the foundation for subsequent limb extension."
"Yes, he's like a machine, fixing each bone with precision! I never thought that the seemingly difficult Kirschner wire fixation would become so easy in Dr. Li's hands."
"If it's so easy to fix these small Kirschner wires, then the fixation pins for the external fixator will be even easier!"
"Look, he's going to start external fixation."
In the operating room.
Li Zheng picked up an electric drill with a 5mm diameter bone needle installed on it.
Use your left hand to fix the patient's left ankle.
Aim the needle tip about 5 cm above the left ankle, pierce the skin and soft tissue from the outside, and directly poke the surface of the tibia.
Director Duan stared at Li Zheng's every move, wanting to see if he could succeed in one go.
Li Zheng didn't adjust the angle much.
Start the electric drill.
“Squeak, squeak, squeak…”
There was a sound of grinding teeth, and in less than 5 seconds, Li Zheng penetrated two layers of cortical bone and pierced the tibia.
Lin Xiaomei handed over the key to unlock it.
Li Zheng unlocked the lock and removed the electric drill.
"The fixation pins of the external fixator should be formed in one go. Repeated adjustments will not only aggravate the tibial injury but also lead to unstable fixation." Li Zheng said as he installed another one.
The doctors present all nodded.
The principle is simple, they all understand it, but no one can guarantee success at once!
Li Zheng also knew their problem. After inserting one, he said, "This external fixator needs to be improved. It should be made so that the angle can be adjusted in all directions. That way, even if the angle of the bone pin is not quite right, it can be corrected by adjusting the frame."
Director Duan's eyes lit up and he said, "That will greatly increase the error tolerance rate!"
All the doctors nodded, especially the young doctors. After all, they lacked experience and it was even harder for them to succeed at the first try, so it was difficult for them to get the chance to get started in a short period of time.
But if the external fixator can be improved, the situation will be very different. Even if you don’t have much experience, you will have the opportunity to get started.
Everyone wanted to ask how the changes would be made, but they knew now was not the time, so they continued to watch the surgery carefully.
Li Zheng used the same speed to insert a bone needle into the tibia below the knee joint at the proximal end of the calf, and then inserted another one above the knee joint on the femoral condyle.
Zhou Ming kept nodding.
This Li Zheng is very knowledgeable about orthopedic mechanics.
Cross-joint fixation can reduce the impact of knee joint movement on external fixation stability, thereby improving limb survival rate.
Of course, this cross-joint fixation cannot last too long, as it will affect knee joint movement. Li Zheng certainly knows this. Once the limb survives, he will replace the external fixator that can extend the limb.
I'm really looking forward to it! Limb extension is something I can't even imagine.
After the bone pins were inserted, Director Duan took the initiative to bring the fixing rod to Li Zheng. The two of them put it on the bone pins together, adjusted the knee joint to a 30-degree flexion position, and tightened the screws.
The external fixator is installed.
"It's great! This rack is more solid than the ones I installed before, and it doesn't have much impact on the operation of the broken ends." Director Duan nodded and commented, looking very satisfied.
At the same time, he felt emotional. He had been a little unhappy about Li Zheng's desire to install the external fixator himself. Now it seemed that Li Zheng had given him a lot of face and he did not deny him at the first time.
Zhou Ming nodded vigorously and said, "The fracture ends have also been aligned. Although the calf is obviously shortened, the force line is well adjusted. Li Zheng, you are truly an orthopedic all-rounder!"
Several young doctors looked at Li Zheng with envy in their eyes.
Li Zheng shook his head and said, "These are just basic skills. As long as you put in some effort, there will be no problem."
All right!
Everyone was speechless.
Although orthopedics is a bit like a carpenter or a decorator, its complexity is far beyond imagination.
Take the external fixation of the lower limbs as an example. Even if it is just the fixation of a fracture, the force line of the lower leg involves the displacement distance, angle, internal and external rotation angle in the front, back, left and right directions. If one aspect is not appropriate, it will cause the force line of the lower limb to be mismatched, and the walking posture will be affected. Even if the fracture heals, lameness will occur.
Over time, this can cause wear and tear on the knee and ankle joints, further exacerbating lameness and further causing a power imbalance, which in turn further aggravates joint wear and tear, and can even affect the hip joint, leading to early osteoarthritis, ultimately requiring joint replacement.
Therefore, although it may seem like a simple treatment, if it is not done properly, it will trigger a series of chain reactions, which will have a huge impact on the subsequent treatment of the patient.
Doctors, especially surgeons, must strive for excellence.
But what Li Zheng said did not seem to be wrong.
As long as you have a solid theoretical knowledge and are careful enough during the operation, you can generally pass the test.
The operation continues.
Li Zheng then fixed the patient's right calf with an external fixator, which was also formed in one go.
After both calves were fixed, everyone worked together to turn the patient over.
Because the blood vessels at the back of the calf need to be treated first.
Li was about to start vascular anastomosis.
"First, anastomose the posterior tibial vein and the great saphenous vein." Li Zheng said.
"ah?"
Zhu Qidong was dumbfounded.
The other doctors also looked confused.
If you want to quickly restore blood supply to the limbs, the priority should be anastomosis of the arteries. How come it is the other way around?
Everyone suspected that they had heard it wrong, but since Li Zheng had mentioned the great saphenous vein, it was impossible that he was wrong.
"Don't you need to anastomose the artery first?" Zhu Qidong asked in confusion.
