After dismantling the thread for Yu Shuilian, it was already more than five o'clock in the afternoon, converted to American time, it should be more than five o'clock in the morning.

This American Robert is quite energetic, either at one o'clock in the morning or five in the morning, this man doesn't have to sleep?

Yang Ping opened the email: Dear Dr. Yang, excuse me again, I'm very sorry, I have used your surgical method to complete a case of knee multi-ligament reconstruction, and the effect is beyond expectations. Now among my patients, there is a special case, I have sent the case information to your mailbox, see the attachment, if you can, please give advice, thank you very much! Robert in New York.

Since the beginning of the review, Yang Ping has communicated with Robert several times by email, and now he has sent case information, it seems that Lao Luo is also a more serious technical maniac.

For this kind of person, Yang Ping generally prefers it, the mobile phone screen is too small, it is still inconvenient to look at the image and pictures, Yang Ping went to the office computer to open the mailbox, downloaded the attached files, and then habitually killed the virus.

The hospital information department has sent several notices on the intranet, do not open the email casually, especially overseas, and must routinely disinfect before opening it to prevent ransomware from being recruited.

Be careful to make the 10,000-year-old ship, this is mail from the United States, or it is better to kill and kill viruses.

The computer is connected to a professional reading electronic screen, and the magnetic resonance picture is very clear, this is a very rare case of a five-year-old boy's knee joint injury, multiple ligament rupture.

Yang Ping has done a lot of this kind of surgery in the system space, much more strange than this, this kind of case, in the system space, is a very ordinary case, but in reality, Yang Ping has not encountered it.

The difficulty of this case lies in the fact that he has a ruptured multiple ligament in the knee joint, and he is a growing and developing child, and the multi-ligament reconstruction itself is very difficult to operate, and in addition, it is a child, and the difficulty is superimposed.

Children are not small adults, children's bodies are growing and developing, and they have their own characteristics, and children of different ages have their own different characteristics, and children's surgery cannot be regarded as a miniature version of adults.

For a five-year-old child, the entire surgery must not damage the epiphysis, otherwise there will be developmental deformities in the knee joint or even the left lower limb.

The epiphyseal line in adults has long been closed, there is no such thing as epiphysis, and adults do not need to consider the epiphysis when doing this kind of surgery, whether it is the tunnel of the tibia and femur, and if the operation of children is done according to the surgical method of adults, the tunnel will pass through the epiphysis.

Therefore, for this type of surgery in children, the starting and insertion points of the ligament should not be placed in the original anatomical position, but should be changed to bypass the epiphysis and put in a special position.

In this way, the ligament starting point and insertion point are changed, and all the anatomical data about the normal ligament cannot be used, which is very difficult to simulate the normal ligament function in this special case.

The surgically implanted tendon, which mimics normal ligament function, is not only stable in the initial stage, but more importantly, it is important to take into account the growth and development trend in the future.

After the tendon is implanted, there is a period of time when it is dead and it takes time for it to be activated; After activation, for a long time, the growth rate of the ligaments does not match the growth rate of the knee joint; After this period of mismatch, entering the period of matching, the stability at this time is the ultimate stability.

The growth of this ligament in the knee joint is not linear for a long time, and the relationship is very complex.

If you can't take these into account, after the operation, it won't be long before the knee joint returns to an unstable state, and a second operation is needed to adjust the ligament tension; After the adjustment, I don't know when, the stability obtained by the operation was lost again, and a third operation was required; Endless surgeries until adulthood do not achieve satisfactory surgical results; In this terrible process, the negative effects of instability on the growth and development of the knee joint have been quietly produced and are permanent.

This is also the reason why Robert, a master of sports medicine, has been unable to come up with a satisfactory surgical plan for a long time.

There are also very few medical devices and implants in children's sports medicine on the market, and only one American company is making such products--- OrthoPediatricS, the only company in the world that focuses on pediatric orthopedic plants.

In China, children's sports medicine equipment is temporarily blank. For Yang Ping, the problem lies in medical devices and consumables, and technology is not the problem.

"Dr. Robert, congratulations on the success of your first operation, the case data you sent has been studied, this case, the operation needs to be performed as soon as possible, the longer the delay, the more profound the impact of the injury on the growth and development of the knee joint. Surgery is complex and involves many factors, many of which are related to growth and development, and are in a dynamic state. However, the operation is not difficult, and if the operation is to be successfully completed, OrthoPediatricS needs to assist, but their current products are not suitable for this patient, and they need to use their flexible production line to design and manufacture a personalized set of instruments and endoplants specifically for the patient. Yang Ping in G City. ”

Yang Ping replied to the email, I don't know if it was the influence of the system space, or if he was too focused on medicine, now he likes to be straightforward, talk and do things, and is too lazy to detour, so as to avoid wasting time.

Yang Ping closed the electronic screen for reading, and it seems that when he is free, it is necessary to write a paper on the reconstruction of shoulder and knee ligaments in children, and popularize relevant knowledge for everyone.

If this knowledge is accumulated in reality, countless doctors can only accumulate it after decades, but Yang Ping can quickly gain experience in the system space, and sublimate the experience into a theory for everyone to use, which is a beautiful thing.

"Oh my God, that's amazing! When I heard the news, my coffee spilled all over the floor, as well as on my desk, computer keyboard, clothes and pants, but fortunately it wasn't very hot. OrthoPediatrics, I've always been in close contact with it, and it's not a problem to produce the device alone. If it is convenient, can we cross the Pacific Ocean, sit together, drink coffee, and talk about this case, if God can give me a little more grace, it would be better to be able to observe Dr. Yang's surgery, I see that on the official website of your hospital, Dr. Yang's department requires Chinese level 4 for international scholars, unfortunately, Robert cannot meet the requirements in the short term, can you visit Dr. Yang as a short-term academic exchange? One week? No, if not, three days? If three days doesn't work, give one day. Robert Jr. is in New York, typing with one hand and cleaning up his coffee on the table with the other. ”

Is this American waiting for the email, the email exchange played with the instant effect of WeChat communication, and just a few minutes after the email was sent, Robert replied to the email.

"I can't give a definite answer to the academic exchange for the time being, so I asked the teaching secretary of the department to contact you. Yang Ping is located in G City, China. ”

Yang Ping called Zhang Lin to the office: "Zhang Lin, now there is an American doctor, Dr. Robert from the New York Special Surgery Hospital, who wants to come over to study surgery, and he said that he can't pass the fourth level of Chinese for the time being, can he come to our department for a few days as a short-term academic exchange?" ”

"According to the regulations formulated by our department, international scholars must pass CET-4 in Chinese, and if they are academic exchanges, there are no language restrictions, but they can only observe, cannot participate in clinical work, and cannot go to the operating table." Zhang Lin is very serious, and now he does this job decently.

Yang Ping gave Robert's email address to Zhang Lin: "Regarding academic exchanges, you can contact Robert directly, according to the system, to see how to arrange." ”

Zhang Lin wrote down the mailbox, a little Gao came, and now he is going to come to Xiao Luo, and the courage on his shoulders is very heavy.

"Dr. Yang, these foreigners come one after another, my burden is not light, you say that you don't manage strictly, if these people are lazy and can't learn things, then smash our signboards, if they are too strict, I am afraid that these foreigners will say that I am not close to people and oppress them." Zhang Lin spoke out about his difficulties.

Yang Ping smiled, this kid is now in a bit of a state: "You can manage how you want, you don't want to do things, you don't want people, as long as you follow the system, there will be no problem." ”

"So I'll rest assured, you can leave Robert's affairs to me." Zhang Lin got the Shang Fang Sword.

In the future, these further studies and exchanges will definitely be indispensable, many of them are still technical experts, those who are interested are fine, and those who are not interesting do not abide by discipline, and there is no strict management system.

In the doctor's office, some trainees were chatting hotly when they saw Zhang Lin coming over: "Teacher Zhang, there is news. ”

Here in Zhang Lin, there is still news? I want to hear it.

"The lawsuit between Director Zhu and Wang Ge will be tried in the second instance next Monday." There is a rule that the trainee showed Zhang Lin his mobile phone.

Not long ago, everyone was eating together, Director Zhu had a treat, and everyone naturally began to care about Director Zhu's affairs, and they were bored to search and see this news.

"I'll take a look at this." Zhang Lin knew about it a few days ago, but he was busy recently and didn't have time to broadcast.

This news was actually broadcast by this regulation trainee, but Zhang Lin is not thinking about it now, and the teaching secretary is what he needs to put his energy into.

"Director Zhu sued Wang Ge for using fake news to infringe on the right to reputation, and the first-instance judgment was: After appraisal by the health department, Director Zhu's surgery met the specifications and was not at fault; After investigation and appraisal by the court, Wang Ge's news violated the principle of seeking truth from facts and was fake news. The court ordered Wang Ge to apologize to Director Zhu in court and in the newspaper, and to compensate 20,000 yuan for reputation damage and mental damage. Wang Ge was not satisfied in court, questioned the results of the health department's appraisal, and refused to admit the results of his fake news appraisal, and wanted to appeal and enter the second-instance trial procedure. The news said that the two had been in a lawsuit for five years, but they didn't see any reports. "Gui Peisheng is suspicious.

"Do you think the original verdict will be upheld in the second instance?" Someone asked worriedly.

"Everyone believes that the law will administer justice for Director Zhu." Someone is very confident.

Director Tian's phone number, there are important matters to discuss, and it is inconvenient for him to come over, so he asked Yang Ping to take the time to go to the Overseas Chinese Building.

Yang Ping and Director Tian have a very good relationship, he has something to do, and he is still in such a hurry, so he naturally will not slack off, and immediately rushed to the Overseas Chinese Building.
