He stared at the results of pet-ct and bone scans, and said: "Chemotherapy can control her tiny lesions, but the tumors on the patient's left leg tibial are no longer controlled. If they are dragged down, it will be even more troublesome to deal with them.

”

Everyone then hurriedly looked at the place Xu Qiu mentioned.

Sure enough, the concentrated area of ​​the left leg tibia is shrinking, but some abnormal concentrated areas appear around it.

"Why……"

"Hasn't there been no infiltration before? Proximal lesions have begun to appear?"

Everyone's faces changed.

The tumor of the tibia is shrinking, but it does not block its tendency to spread around it.

If the surgery is not done as soon as possible, the legs will definitely not be preserved.

At this moment, the problem became extremely clear.

Neoadjuvant chemotherapy is indeed effective, and the tiny lesions in each metastatic site are controlled. After a few weeks of chemotherapy, the survival rate will be higher.

However, the distal metastasis was controlled, and the direct spread of the proximal end could not be curbed...

If you wait any longer, the tibia will probably not be protected at all, so you can only undergo extensive resection.

Either drag it and amputate it safer, which is likely to save your life.

Either perform surgery immediately to prevent the loss of the last chance of limb conservation, but the risk will be much higher.

"Considering that the condition has changed, we have to let the family make a choice again." Xu Qiu thought for a while and said.

He sent someone to explain the situation to his family, and the consultation here was not delayed and continued.

"If the patient chooses to amputate, just do it directly. Our hospital's orthopedics are very experienced in this area."

After Xu Qiu said this, the orthopedic doctor nodded in agreement.

Linyi's orthopedics have always been very strong. Before Xu Qiu came, hand surgery and orthopedics were relatively famous departments in Linyi.

In the past two years, orthopedics has been stolen by the brain surgery and emergency departments, but they are secretly trying to do so and are unwilling to fall behind. Therefore, now orthopedics are also full of talents and surgical elites are frequently released.

After Xu Qiu finished speaking, he said, "If you have limb protection surgery, you have to make a careful plan."

The difficulty of limb conservation surgery is not comparable to amputation.

Moreover, there is also a key question - what kind of reconstructed materials are used.

Conventional materials must be inactivated and replanted tumor bone shells, then filled with bone cement, or transplanted with allogeneic bones preserved in low-temperature bone bank, but both have considerable defects.

The most important point is that bone cement will emit a lot of heat during solidification. Under normal circumstances, most tissues in the body can withstand this temperature.

But the problem is that everyone has chosen to perform limb preservation surgery, so how can the damage to the surrounding bone tissue be mild? Therefore, bone cement coagulation often leads to damage to the surrounding blood vessels, muscles and nerves.

Especially nerve damage, once it occurs, it is almost irreversible.

This is also a sequelae of many patients who choose bone cement surgery: sensory nerve abnormalities in the area of ​​the reconstructed bone.

As for allogeneic bone transplants preserved in the low-temperature bone bank... Not to mention whether there is any suitable one, rejection reaction is a difficult problem that cannot be avoided.

Its biggest disadvantage is that rejection reactions are extremely prone to occur, and once they occur, the opportunity to save your limbs will be completely lost.

"This patient... should be able to use rubber artificial bones?"

Just as he was thinking, Xu Qiu suddenly had an inspiration.

At the World Championship, he once developed Guo rubber artificial bone.

This material has amazed the judges of the World Competition and experts in the field of orthopedics at home and abroad.

Traditional bone repair defects have always had huge defects and lack of materials!

What can be used are nothing more than autologous bones, artificial bones, and allogeneic bones.

Autologous bones are used to remove the east wall and repair the west wall, which is too restrictive; the defects of allogeneic bones are too obvious, the incidence of rejection reactions is very high, and the consequences are serious; only artificial bones can be used.

However, artificial bones are difficult to achieve balance between plasticity, resistance to liquid phase collapse, and degradation and regeneration.

For example, the bone cement that is mainly considered, its plasticity and liquid phase crumbing resistance are very good, but it cannot degrade and has a series of problems such as heat dissipation.

In the absence of better materials, bone cement is indeed the best choice for most patients with bone defects.

But for Xu Qiu, he also has the big killing weapon of rubber artificial bone!

As its name suggests, rubber artificial bones can be shaped at will, and have excellent filling effect. They also have excellent anti-liquid phase rupture. They can stabilize surgery in various aqueous environments. The bones can be completed in just three to six months of implantation.

regeneration!

It surpasses bone cement almost in all aspects.

Of course, after he came back, he handed over the rubber artificial bone project to Lin Xie - the other party is an old skeleton reconstruction expert and is second to none in China. It should not be too difficult to transform Xu Qiu's achievements into clinical application.

Now it's just right for acceptance.

He quickly called Lin Xie.

After a while of greeting, Xu Qiu explained his purpose.

Lin Xie said ecstaticly: "Now that we have applied super-dispersed technology to the industrial chain, I estimate that mass production will be achieved in a few months, and the quality will not be too different from the products produced in the laboratory!

"And, during this period, we have further improved the sustained release of calcium ions during hydroxyapatite degradation, and patients will have a better internal environment during osteogenesis!

"We are planning to recruit volunteers in two weeks... It is better to choose a day than to meet the day!"

Xu Qiu hung up the phone.

Next, it depends on whether Jiang Donger is willing or not.

If you continue to persist in limb preservation, you can ask about your intention to use rubber artificial bones.

...

An hour later, the consultation was over and the surgical plan was finally completed at the meeting.

As soon as Xu Qiu left the conference room, he rushed to the conversation room without stopping.

Jiang Dong'er and Jiang's parents have been waiting for more than ten minutes.

"I've been waiting for a long time." Xu Qiu pushed the door open and entered.

Jiang Donger's parents immediately stood up, and Jiang Donger, who was unable to move, also looked up and her beautiful eyes lit up in an instant.

"Have you decided, limb preservation or amputation?" Xu Qiu said straight to the point.

If you choose amputation, the hospital will be very relaxed and the patient will also get safer results, at the cost of losing a leg.

The risk of limb preservation surgery is much higher.

Jiang Dong'er's parents did not speak, but looked at Jiang Dong'er together.

The three of them had already agreed... Xu Qiu saw the subtext of this action.

Sure enough, after a slight silence, Jiang Dong'er said firmly: "Doctor Xu, I'll do limb protection."

"Not unexpected." Xu Qiu nodded.

Jiang Donger has a high degree of trust in him, and he is indeed very sure to win the operation...

Xu Qiu said this and sat down. He handed over a document. This was the document that Lin Xiecai faxed, and it was the introduction of the rubber artificial bone.

"This is..." Jiang Dong'er's parents said in surprise.

Xu Qiu explained: "Traditional bone defect repair surgery uses more bone cement, but the advantages and disadvantages of this reconstruction material are obvious...

"But a brand new bone defect reconstruction and repair material is being developed in China, which is the rubber artificial bone you see in your hands."

Hearing the last five words, Jiang Donger's expression suddenly became vivid. She widened her eyes and said in surprise: "I know, I know, it's the scientific research results that scored 96 points in the World Championship, right?"
