Sisi’s X-rays, CT, MRI, and PET-CT are all opened on the large electronic reading screen.
The last operation at an external hospital had amputated about 20 centimeters of the middle section of the femur. In order to gain lower limb function as quickly as possible, a customized titanium alloy prosthesis was used to bridge the femur and make up for the 20 centimeters missing. The prosthesis was inserted at both ends.
The medullary cavity is fixed with bone cement.
This is a palliative approach, the purpose is just to allow her to obtain a functional lower limb within a limited time, able to walk, and easy to care for. Her osteosarcoma has metastasized in many places throughout the body, and other methods are used, such as fibula transplantation and allograft
Bone transplantation or Ilizarov's bone lengthening technique are not suitable. The recovery time is too long and are not suitable for a patient with advanced cancer.
"Can a total femoral prosthesis be replaced? Using 3D printing technology?"
Song Zimo suggested that 3D printers in orthopedic laboratories can already be used. This machine is industrial grade and is equivalent to a 3D printing machine.
Yang Ping shook his head: "As an organ, the femur cannot be simply replaced. There are many muscles attached to it, and there are joint capsules and ligaments attached to both ends. These tendonous soft tissues are firmly attached by the mechanism of tendon-bone healing. The joint capsule
and ligaments maintain the static stability of the hip and knee joints. The muscles not only maintain the dynamic stability of the joints, but also provide the power for movement. To perform total femoral replacement, the problem of soft tissue attachment needs to be solved, otherwise the femur can only play a supporting role.
There is no movement function, and even the supporting role can only be played a little. The soft tissues and bones of the human body can heal, but cannot heal with artificial materials. If this problem is solved, it will probably be a breakthrough in orthopedic technology. We cannot use this method at present.
However, we can do a project to study it."
"Amputation?"
Xiao Wu’s opinion, since it cannot be replaced, it can only be cut off.
This is a feasible solution. The tumor and the invaded femur are removed. However, after the removal, only a little bit of the femur is left at both ends. The right lower limb will lose its function due to the loss of the femur. Using a customized prosthesis, it has already
Unable to obtain effective control.
"It has spread throughout the body, so amputation is of little significance. Keeping the limbs will at least make you feel better psychologically."
Zhang Lin also expressed his opinions. Everyone was very positive and Yang Ping would not criticize them if they were wrong.
"What's your opinion? Senior brother?" Song Zimo watched Yang Ping turn over the film, but never expressed his opinion.
"Take out the prosthesis that originally bridged the femur, cut out the tumor and the invaded femur, use the Ilizarov technique to lengthen the bone, and give her a normal femur." Yang Ping thought for a long time and said.
Song Zimo thinks this method is too idealistic and unrealistic: "She has late-stage osteosarcoma. Are you planning to cure it completely by treating her like this? Impossible."
Song Zimo did not say the cruel subtext: her survival period may be shorter than this extended duration. A progress of one millimeter per day, even twenty centimeters, would take more than two hundred days. Can she persist for so long? "I know that a radical cure is impossible, but I want to work hard in the best direction and go as far as I can." Yang Ping is very determined. He wants to fight for it, even in a Quixotic manner.
Everyone was silent, and Yang Ping continued to flip through the film alone: "I know that in her condition, she should give up medically, but I want to work hard and work towards the best goal, even if it takes a step forward!" Song Zimo put his hand on his shoulder: "I don't agree with your point of view, but I support you."
"I support it too!" Zhang Lin Xiaowu also cast an encouraging look.
"Using the infrared navigation equipment in the operating room, we will give her a three-dimensional reconstruction of the infrared scan of the tumor, use indocyanine green for contrast, and then combine the three-dimensional reconstruction images of CT and MRI to obtain a complete tumor image, which will be imported into the host of the surgical navigation system.
"When the time comes, we will use infrared navigation to perform the surgery." Yang Ping removed the hand holding the mouse.
"These reconstructions are all completed by their own machine software and cannot be synthesized into one image." Xiao Wu is relatively familiar with medical equipment.
Yang Ping told Xiaowu: "We designed a software ourselves to do comprehensive reconstruction. Xiaowu, don't you have expertise in this area? You can find a few students from Nandu University of Technology to work together to do it."
"This project is huge!" Xiao Wu used to help his tutor make these things in school.
"If it's not big, it's not called a project. Landing on the moon is difficult, but it's still possible. Song Zimo, please lead them to establish this project. They don't need to apply for other projects, just apply for the hospital's Overseas Chinese Fund. It's so fast." Yang Ping said.
Everyone has confidence.
Hearing that Yang Ping had made up his mind, everyone was very encouraged and eager to try. Senior brother is going to make some big moves, produce some scientific research results, write high-quality papers, and everyone will be evaluated for professional titles in the future.
The soul of a team is very important. It must have the right direction and firm determination, just like an erected flag. Only then can everyone gather under the flag and move forward unremittingly towards the goal. Yang Ping has achieved this.

"It's my birthday on Saturday. I'll have a birthday party at home in the evening. I'll definitely come over if I have time. They're all from our circle. Shao Wei and Lao Zhou will come. By the way, I'll introduce you to some friends."
After just discussing Sisi's condition, Su Nanchen called to invite instead of sending a WeChat message. As a friend, I must attend, but I can't go empty-handed. I have to bring some gifts.
Yang Ping was in a dilemma. He was really not good at giving gifts. He called Song Zimo, Xiao Wu, and Zhang Lin over to discuss the matter together.
No matter what you say or what I say, no good conclusion can be drawn. None of these old men have any good ideas, including giving away high-end pens, surgical goggles, and the latest English orthopedic monographs. They have all kinds of ideas. Let's go to Xiao Su. Girls should know better. Yang Ping went to Xiao Su again and discussed with her: "What kind of gift do you think I should give? It's impossible to seal a red envelope, it's so tacky."<
/p>
Xiao Su had a lot of ideas. After thinking about it, he said: "I have an idea. You are all surgery fans. Let Xiao Wu and the others help you make an animated demonstration of the key steps of the multi-ligament reconstruction surgery of the knee and shoulder joints."
The secrets of surgery and surgery are thoroughly explained. Combined with your usual surgery videos, burn them into a set of CDs and give them to him as a gift. He will be very happy. For people who are obsessed with surgery, nothing is more important than gaining valuable surgical experience. I have packed the box
Come and help you find someone to do it, it will definitely satisfy your friend."
"Great! This is a good idea. It seems that my brain is very useful for surgery. I really don't know anything about these things in life. Xiao Su's idea is good. This gift is unique and very valuable. That's it."
Yang Ping decided immediately.
Then he approached Song Zimo, Xiaowu, and Zhang Lin, and asked them to help create animations and burn discs. Song Zimo had done so many surgeries with himself and was well versed in the mysteries of this type of surgery. Xiaowu could make animations, and Zhang Lin was responsible for the text explanation.
That's it.
"One meal, choose any place! It must be completed before Friday night." Yang Ping set the conditions.
Yang Ping hesitated for a moment: "We are all brothers. We don't see each other when we look up, so we should be gentler."
"It's just a few days, I'm afraid it's too late, right?" Song Zimo shook his head, looking very embarrassed.
"Yes, time is so tight, let's forget about making a PPT, animation is too time-consuming."
"Textual explanations have to convey the meaning, and it cannot be thought up in a few days."
Yang Ping looked at these guys, colluding with each other, shaking their heads, looking like "It's difficult, it's difficult!"
"Okay, pick the location as you like, and I don't care how serious the attack is." Yang Ping understands these things.
"Well, although time is tight, it shouldn't be a big problem if everyone works overtime." Song Zimo immediately changed his mind.
Zhang Lin Xiaowu also echoed: "We are all brothers, let's work overtime and ensure delivery before Friday night."
A bunch of foodies! Yang Ping warned: "Call the fat guy too."
Zhang Lin was anxious: "What are you calling him for? Are you really going all out? He can't help with anything, and how many of them can he eat? I'll double the bill for you!"
"I went all out and asked him to help me choose a place and order food. None of you can compare to his expertise in this." Yang Ping explained.
No one refutes, this is the truth. When it comes to eating, when it comes to professionalism, Fat Brother really kills everyone in an instant. After all, he was the former president of the Food Association.
"Bring your girlfriend here!" Su Nanchen sent to WeChat.
What should we do about this matter, take Xiao Su? We have to find Xiao Su again. Yang Ping goes upstairs and rings the doorbell of the operating room, and Xiao Su comes out.
The door to the operation opened, and Yang Ping did not go in. He stood at the door and showed Su Nanchen's WeChat message: "He asked me to take my girlfriend with him? How should I reply to him? Are you free to go together?" Yang Ping
His face is a little red.
Xiao Su chuckled, and then looked embarrassed: "I'm sorry, I have to go home on Saturday night. It just so happens that I have family members and it's my birthday, so I can't go with you."
"What a coincidence!" Yang Ping was a little disappointed.
"How about? I'll tell my family and accompany you there?" Xiao Su lowered her head and pursed her lips.
"That's not okay. I can go alone. It's necessary for you to accompany your family. It's not like I need you to accompany me. It's okay. I can just explain it to him." Yang Ping said.
"If there is no need to explain, the more you explain, the more unclear it becomes."
The phone was in Xiao Su's hand. Xiao Su held the phone and twirled it with her fingers: "Huh! I'll reply for you. Tell him directly that you haven't dated a girlfriend yet. Let's see what he means. Isn't he testing you? He wants to give you something.
Can you introduce your girlfriend?"
"No, are you angry?" Yang Ping heard Xiao Su snort.
Xiao Su pouted: "I won't be angry. Someone is so active in helping you introduce your girlfriend. I'm just happy. Haha, it shows that I have good taste. Maybe he has a sister or something in his family that he wants to introduce to you.
You are destined to have a surname named Su."
"Don't think too much, I just mentioned it casually," Yang Ping said.
"If he introduces you to a girlfriend, you won't be tempted, right?" Xiao Su's long eyelashes flashed.
Yang Ping shook his head: "I want to be tempted, but I can't."
"You--"
"Because my heart is already filled with one person."
Xiao Su turned her anger into a smile, stretched out a finger, and lightly tapped Yang Ping's forehead: "That's pretty much it."
