In Cheng Liquan's office, Su Nanchen and Cheng Liquan stood in front of the reading lamp.

"Su Shao, what should I do? I didn't look closely at the time before I fell into this pit. Boss Cheng's face turned red.

Su Nanchen was very calm: "Don't worry, this is not to the edge of the pit and stopped, it hasn't fallen yet, it's not that you are not careful, few people have experience with this kind of case, it's too special." ”

Boss Cheng slapped himself: "Su Shao, it's all my fault for being anxious, if I listen to you, I won't take this kind of patient for the time being, nothing will happen." ”

"It's useless to say this now! Wait for him to come over tomorrow, we will study and study together, the operation has not been done yet, what are you afraid of, it is a big deal not to do it. Su Nanchen comforted him, complaining afterwards, to no avail.

If you don't admit it before surgery, you will swallow the bitter fruit after the operation, and you will have no chance to admit it.

When Su Nanchen came over last time, he was in a hurry, did not see the patient, and did not study the patient's imaging data, this time he came here and found that this patient was too special, the intercondylar fossa was severely deformed, bone hyperplasia and tamponade, and the posterior side of the tibial plateau was partially defected, and the defect was just the original posterior fork tibial insertion site, and the patellofemoral joint was still underdeveloped, so he urgently did a CT three-dimensional reconstruction of the knee joint.

Su Nanchen and Boss Cheng looked at the CT three-dimensional reconstruction in front of them, their brows were tightly locked, the quadruple reconstruction was already extremely difficult, and with this special situation, the difficulty of the operation increased exponentially.

This operation, on the basis of quadruple reconstruction, also needs to do intercondylar fossa plasty, this intercondylar fossa is not easy to do, not to restore it, but to design a condylar fossa shape to meet the various needs of the operation, otherwise the operation will fail, causing bad consequences.

If it weren't for the doctors who are experienced in the reconstruction of multiple ligaments in the knee joint, they would not have realized this bad consequence at all, but fortunately, Su Nanchen has experience in this area, otherwise he would have stepped on the thunder.

"I checked later, this patient was seen in Yunjian, they said that the schedule was too tight, in fact it was not the case, they contacted Professor Ye, after Professor Ye looked at the patient's imaging data, he thought it was too difficult, especially this intercondylar fossa could not be done, so he dismissed. They prevaricated this patient to me and deliberately harmed me, which is too filthy. Cheng Liquan regretted it very much, his face was full of sweat, this time Su Nanchen saved him, if it weren't for Su Nanchen, he wouldn't know the serious consequences of the matter at all.

"Those people, they're vicious! This is digging a pit for me to jump, and I almost jumped, and a single operation smashed the signboard. Cheng Liquan was a little afraid.

"The operation will definitely not be done, the person I invited you, no matter how powerful they are, it is impossible to complete this kind of operation, but I will take him over tomorrow and study it together, I have already made an appointment with him." Su Nanchen thinks that this case is too special, and Yang Ping must be invited to come over, even if the operation is not done, it is necessary to see the patient and study it.

"Listen to you, your friend's fee, I will still pay it according to the operation, and I will never embarrass Su Shao." Boss Cheng wiped his sweat.

Su Nanchen didn't speak, he was still reading the film on the film lamp, no matter how powerful Yang Ping's surgery was, it was impossible to complete this kind of operation.

This intercondylar fossa plasty cannot be done at all, and if it is done conventionally, it will definitely cause patellar joint instability and apraxia of the posterior fork of the reconstruction, which is the reason why Professor Ye does not dare to do it.

If you want to do it, you need to design a software, build a model, use 3D simulation technology, reconstruct the intercondylar fossa on the computer, through continuous simulation trial and error, and finally design an intercondylar fossa, using 3D printing or virtual reality technology, the doctor will shape according to the designed mold, even so, the surgeon must have a strong spatial imagination ability, in order to barely make a qualified intercondylar fossa.

Su Nanchen sent the patient's information to Yang Ping's mailbox, Yang Ping was playing ball, and he didn't see Su Nanchen's message.

"Ding-dong! Task: Fledgling, go to the outer hospital to perform a case of knee multi-ligament reconstruction, the surgical level is perfect, the reward is 40,000 points, the task timeliness: within 24 hours! ”

When I was playing, the system released a task, strange, my own five-link reconstruction did not release a single task, this four-link reconstruction actually released a single task, and the reward score reached 20,000 points, is this four-link more difficult than the five-link?

Now the system is very good at picking tasks, and the reward score is also high, not a particularly difficult operation, it is too lazy to care, high difficulty, high reward, this seems to be the current principle of the system.

After playing ball, during the break, Yang Ping took a cursory look at the patient's information on his mobile phone, and sure enough, this quadruple was more difficult and one grade higher than the last five-link reconstruction.

In the evening, Yang Ping began to study the case in detail.

It's actually a hidden quintagram, more complicated than the pentagram I made a few days ago, why? Because on the basis of quadruple, it is necessary to do intercondylar fossa molding.

The five-link I did by myself is the quadruple plus the habitual dislocation of the patellofemoral joint, which is the addition of the intercondylar fossa on the basis of the quadruple, and the anterior cruciate ligament reconstruction I did before has the intercondylar fossa plasty.

However, this intercondylar fossa is more difficult to shape than the previous one, and the previous patient only needs to follow the mirror image of the condylar fossa on the unaffected side.

In this case, the entire intercondylar fossa was severely deformed, the posterior side of the tibial plateau was still partially defective, and the patellofemoral joint was dysplasia.

Patellofemoral dysplasia indicates that the patient's previous intercondylar fossa was abnormal, as for what happened, who knows; The posterior tibial plateau defect indicates that when reconstructing the posterior fork, it must be considered that the femoral insertion point of the posterior fork on the formed intercondylar fossa is not in a normal position, and this should be taken care of by the molding, so an extremely special intercondylar fossa needs to be formed.

If the intercondylar fossa is performed with a mirror image according to the normal condylar fossa on the contralateral side according to the previous method, the operation will definitely fail, resulting in the loss of the reconstructed posterior fork function and patellofemoral instability.

Originally, the patient can barely walk now, but it is likely that after the operation, due to patellofemoral instability, frequent lateral dislocation, resulting in difficulty in walking, can walk without surgery, and cannot walk after surgery, can the patient accept it?

In this operation, we must conceive the shape of an intercondylar fossa by ourselves, this form has no template control, and several conditions must be met at the same time, not only to provide the best tunnel entry point for the ligament, but also not to cause patellofemoral joint disorder, but also to cause the impact of the ligament, this difficulty from beginning to end is not a recovery, but a process of reconstruction, which is equivalent to designing an intercondylar fossa with strict parameter requirements, a slight error, and the operation collapses.

The core of the super training program is to cultivate the ability to compose the brain, which is not a simple static composition, but a dynamic, connected and logical composition.

Yang Ping's ability to compose his brain is constantly improving, this time he is very easy to construct static graphics, once formed, without making many supplements, but the construction of dynamic images, it is still very difficult, repeated many times, constantly corrected, supplemented, strengthened, in order to form a picture.

The graphics change in the mind, sometimes they need to move, sometimes they need to switch, one intercondylar fossa after another, and then the ligaments are implanted in the ideal position, no! Then continue to modify the intercondylar fossa, implant the ligaments again, and repeat many times, several sets of ligaments can be implanted to obtain the best function and balance; However, there is an impact in the process of flexion and extension, and the modification continues until the impact disappears completely; Patellofemoral instability reappeared, and he gritted his teeth and continued to revise it, with constant trial and error. When this problem was finally solved, my forehead was already full of sweat, my clothes were almost soaked, and my brain power was too much to consume.

Yang Ping repeatedly checked the final intercondylar fossa shape several times, and there was no problem, so he memorized it in his mind and prepared it for tomorrow's surgery.

"This patient's intercondylar fossa needs to be formed, and it is extremely difficult to form, come and have a look tomorrow!" Su Nanchen's message.

"I've read the information, and it's really difficult, but it's not a big problem." Yang Ping replied.

This guy, this kind of surgery is not a big problem, it is really a miracle of surgery, and I still haven't looked carefully at the image data.

At half past eight o'clock in the morning on Sunday, Su Nanchen arrived at Sanbo Hospital on time, and at about nine o'clock, Yang Ping had already arrived at Liquan Hospital.

In order to show his attention, Boss Cheng stood at the door of the hospital, Su Nanchen appeared in the field of vision with Yang Ping, he looked at it intently, no, how could someone who is better than Professor Ye be so young, no matter how clumsy he is, he can also see the approximate age of this person, isn't this only in his twenties? What is the concept in his twenties, at most a small indicator, what kind of road did Su Nanchen play this time?

Boss Cheng thought about it, Su Nanchen has always been true to his words and deeds, so he doesn't have to worry about this problem at all, the person he invited must be a master. It's a pity, if only the patient was an ordinary quadruple reconstruction, this operation was done today, filling the gap in Liquan Hospital, marking that there is no technical gap between Liquan and Yunjian. But this patient can't --, surgery, alas! Boss Cheng sighed, unwilling.

As a businessman, Boss Cheng was shrewd and sleek, he didn't show any thoughts on his face, and he didn't even show his careful thoughts, so he stretched out his hand.

"Yang Ping of Sanbo, Dr. Yang!" Su Nanchen introduced.

"Hello, Dr. Yang, I'm glad to meet you, Cheng Liquan-" Boss Cheng was warm and kind, making people feel familiar at first sight, he immediately handed over the business card respectfully with both hands, and bowed slightly.

Yang Ping took the business card: "Boss Cheng, I have admired the name for a long time, in the medical circle, who doesn't know the name of Boss Cheng." ”

The fame is there, but Yang Ping really knows Cheng Liquan's name for the first time.

The three of them chatted while walking, this sports medicine center is really good, the decoration is designed by professional people, even the slope of the stairs, the width of the steps, the height of the handrails, and the color matching are very particular.

High-end is not only a technology, but also an experience.

This person is in his twenties, but this demeanor, every word and deed, there is no frivolity and instability at all, but everywhere reveals a strong calm and self-confidence, Chaoshan people are good at doing business, businessmen are good at observing people, Boss Cheng observes from the secret, Su Nanchen, a friend, looks at the temperament, is really a master.

The beautiful nurse leads the way in front, the slim nurse uniform outlines the figure exquisitely, and the professional smile makes people feel very comfortable, and this hospital is very attentive.

Yang Ping has heard of these specialized hospitals to some extent, and he is also a little prejudiced, but Su Nanchen's friend opened it, and it should not be too wild.

Intuitively, this hospital is still very formal, and Boss Cheng keeps introducing his hospital all the way.

"Let's sit in my office and take a break!" Boss Cheng said.

Yang Ping waved his hand: "No need, let's watch the film first, and then look at the patient later." ”

When everyone went to the doctor's office, the reading lamp was already full of video films, and Yang Ping walked to the lamp and carefully looked at the patient's films.

Everyone gathered around, two doctors, several master's students, all of them were trained by Boss Cheng, the pillar of the hospital, and now the doctor's and master's jobs are not very optimistic, especially in G City, it is difficult for good public hospitals to gain a foothold, and some can only seek second, go to some private hospitals, or large comprehensive private hospitals, very few, or such small and refined specialized hospitals.

Yang Ping's eyes narrowed slightly, and his sharp gaze swept around the film.

Boss Cheng held his breath, he still hoped that this operation could be done, although the hope was very slim, although this was an operation that Professor Ye gave up, Professor Ye was unwilling to do it, who else in the country could do it? When it comes to this type of surgery, others are at most on the same level as Professor Ye.

Seeing that Yang Ping didn't speak, he just stared at the film on the reading lamp, Su Nanchen and Boss Cheng didn't have a good time to speak, they just waited quietly, originally this kind of operation, it was a bit not good to call people over.

After reading it, Yang Ping said, "Let's go, go see the patient." ”

Boss Cheng asked the doctor to lead the way and took Yang Ping to the ward to see the patient, the wards here are all suites, and the decoration is very luxurious.

Yang Pingzai inquired about the medical history, carefully examined the patient, and grasped sufficient information, and was already sure in his heart.

Go back to the doctor's office.

"How?" Su Nanchen asked.

Boss Cheng waited for the result.

"Send the patient!" Yang Ping said lightly.

Sending a patient? Is this possible to do?

Su Nanchen is not sure, what he said is true or false, this operation can also be done, this guy is really crazy.
