Six Hundred and Thirty Second Look Forward To

The human body can be roughly divided into three cavities, the chest cavity, abdominal cavity and pelvic cavity.

Especially the pelvic cavity, with the selection of natural evolution, is very different.

For example, Europeans and Americans, because in ancient times, their medical technology can not be said, all diseases are bloodletting, minor illnesses are released, serious illnesses are released, and even one of their presidents was bloodletted to death.

This has also led to the fact that modern European and American men like women with very, very wide pelvic cavities, because only such women can survive.

Therefore, they think women with a pelvic cavity as wide as a door panel are the most beautiful. In fact, there is a reason for this, just like the old lady who loves to gossip in the neighborhood sees someone's new daughter-in-law, the first thing she sees is not her face. , but pigu eggs.

Because the pelvic cavity is wide, the risk of pregnancy and childbirth is relatively small.

The hip joint is the outermost tissue of the pelvis. Many people, especially some young people, will experience a rattling sound in the hip joint when they walk for a little longer, just like someone snapping their fingers.

This is because although the length of the legs has not yet reached the error of lameness, it has reached the limit of the body's adjustment.

If you don’t deal with the long-term uneven force, and it surpasses the body’s compensation, then over time, it will lead to arthritis. The easiest way is to put a slightly thicker shoe inside the shoe on the slightly shorter side. A little insole.

The surgical plan used by Zhang Fan is the posterolateral approach. The doctors in the electronic classroom watched quietly. Although they didn't say anything, they still admired Zhang Fan's level in their hearts.

At Zhang Fan's age, in their department, he was either an intern or a postgraduate student.

But Zhang Fan, he has already started to perform orthopedic surgery, which is regarded as the top-level surgery, and he chooses the most complicated surgical method, but the best way for the patient to recover.

This left everyone speechless, what could be said, what else could be said? But when the bone was sawed open, Zhang Fan was about to put on the prosthesis.

In the electric classroom, like water pouring into hot oil, there was a lot of noise. They were all doctors from the Department of Orthopedics, or top-ranked doctors from large hospitals, and none of them was clear about the steps of the operation.

The most difficult part of hip replacement is the placement of the prosthesis. If the placement is too long or too short, you don’t even need to think about it.

Also, if the measurement of the prosthesis is inaccurate, after the patient is discharged from the hospital, maybe a big lump will come out of the piggu, just like a big peach growing on the piggu.

Then there is the thigh on the affected side, and there is a big split like a big windmill!

If it is lighter, you need to go to the hospital, and let the doctor pull the leg to return the prosthesis to the acetabulum, and if it is heavier, it may cause permanent disability to the patient.

Therefore, when Zhang Fan directly skipped the measurement, the doctors' eyes widened.

"Nonsense! Director, he..."

Lin Cong listened to the commotion in the electronic classroom and watched Zhang Fan's movements. He was actually puzzled, but thinking about Zhang Fan's skills and Zhang Fan's personality, he felt that Zhang Fan would not appear so important. mistakes.

But, at this time, can he stand on the sidelines? No, not for other reasons, just for the patient, just because he is the director, he has to ask.

He didn't stop or pay attention to the noise in his ears. He stood up and picked up the phone to connect to the operating room.

"Doctor Zhang, is it because the measuring tool is not convenient, or I am asking them to change you to a brand of measuring tool."

Lin Cong's tone seemed very relaxed, but his face was serious. If Zhang Fan really forgot this measurement, needless to say, he would immediately stop Zhang Fan from continuing the operation.

"Oh, Director Lin! No need to change it, it's very easy to use."

Zhang Fan said without raising his head.

"Uh!" Lin Cong was choked by Zhang Fan, "Why didn't you measure it?" There was no way, Lin Cong wanted to ask in a roundabout way, but Zhang Fan didn't say anything.

Everyone has their own habits,

Each has its own hobbies. The most unbearable thing for Zhang Fan on the operating table was being disturbed.

At the beginning, it was because of Fan Zhe, a habit that Zhang Fan cultivated with all his efforts. Being disturbed on the operating table was like breaking Zhang Fan's food stamps. Zhang Fan was very, very annoyed.

"Gibosn's surgery was improved by Moore, and Moore's surgery was improved by Dr. Shibi. Haven't you thought about continuing to improve it? Isn't it a waste of time to measure?"

The tone was flat, and the foreign language was not standard, but the meaning was so strong that Lin Cong was speechless, and so strong that the doctors in the electronic classroom were stunned.

Improvement, especially the improvement of surgery, is easier said than done. Most of the operations that are popular now are almost done in the same way at the beginning, and they are still done in the same way now.

That is to say, occasionally one or two people with halos dare to improve and improve, and most of the rest just follow the rules. Even if they follow the rules, most of them can't learn well. Improvement is not easy.

"Improve? He wants to improve? How does he improve?"

One by two, they looked at the doctors sitting next to each other, with question marks in their eyes.

After Dr. Wang heard Zhang Fan utter such awesome words, he almost threw away the hook in his hand. These words were too scary! ~

"Doctor Zhang, how did this place improve?" He really couldn't suppress the doubt in his heart.

"With the acetabulum as the center point, establish a precise three radiating moment lines in the mind, and the outer line is perpendicular to the long arm B-X line.

The lower measurement line sets the A1-B1 high eccentric moment perpendicular to the body.

The inner line is perpendicular to the pubic bone, making a straight line from A2-B.

Two points can fix a straight line, three points can fix a triangle, and the acetabulum, pelvis, and lower limbs are exactly a triangle! "

Zhang Fan said while doing. This method was summed up by him after many days and nights of systematic practice.

This method combines the patient's MRI and CT to locate the position of the hip very accurately.

In layman's terms, it is to determine the starting point and end point of the bone, and the position is directly fixed.

If you know this method, the hip replacement surgery will become very simple. However, this method requires the doctor's sense of space, torque calculation ability, and pressure load estimation of the lower limbs.

To be honest, constructing an accurate structural map of a patient in his mind is not something that ordinary doctors can do.

And Zhang Fan relied on countless times of training, relying on the strict requirements of the system, and failed again and again, finally tempered his own surgical methods.

His method is more accurate than conventional surgical methods. As long as human factors are involved, there will be errors to some extent. However, Zhang Fan can determine the position directly at the source. It can be said that as long as the material does not change, he can do it. There is no change in the operation, it is so precise.

Moreover, it saves time even more, at least it can reduce the wound exposure by more than half an hour, and how many half an hour does it take for the entire operation.

It is estimated that many people may have turned on a mechanical alarm clock with a screwdriver when they were young teenagers, that is, the big devil.

In fact, the sophistication of the human body, in comparison, is definitely much, much higher than the complexity and sophistication of the machines made by humans themselves.

Moreover, the most important thing is that the organs of the human body have the function of self-recovery and self-regulation.

Not to mention anything else, just talk about the size of human feet. In fact, there is a certain degree of surprise.

In fact, the upper and lower limbs also have different lengths. If the length of the lower limbs exceeds two centimeters, it will exceed the compensatory ability of the human body, and a limp will appear, and it is called a so-called limp when walking.

There are three difficulties in hip replacement surgery, and the most frightening one is the occurrence of uncontrollable fat embolism.

As the saying goes, eating meat is worse than gnawing bones, and gnawing bones is worse than licking fingers. The fragrance is because of a fat.

There is a lot of fat in the marrow cavity of the bone, and the essence of the bone marrow is actually phospholipid, which is the so-called fat.

Once this is opened, a large amount of fat tissue will liquefy and then enter the blood. To be honest, this situation is unavoidable according to the current medical level.

Fat embolism is one of the biggest uncertainties in orthopedic surgery. How scary is this uncertainty? It can be said that once the fat embolism enters a more important organ, such as the lungs, to be honest, even if the patients are in the hospital, most of them are too late to be rescued.

In order to avoid it as much as possible, orthopedic surgeons try to speed up the operation and reduce the damage as much as possible, but orthopedic surgery is almost a destructive treatment, so it is very contradictory.

However, Zhang Fan's method saves time, which means that his method can more likely avoid fat embolism in patients.

Zhang Fan said while doing. Whether it's Dr. Wang on the operating table or the doctors in the electronic classroom, their brains quickly want to repeat Zhang Fan's way.

Difficult, too difficult. Especially Dr. Wang, the bean-sized beads of sweat on the tip of the nose under the mask slowly seeped out.

It's too difficult, my head hurts, and it's too difficult to copy.

"Prepare the bone cement, it will set in two minutes." Zhang Fan didn't stop. He said something to the big girl Dongshan who was on the edge of the operating table.

And Dongshan girl looked at Zhang Fan with admiration. Although she couldn't understand what Zhang Fan said, she could hear every word Zhang Fan said clearly, but when they were connected together, it was like a pile of gibberish characters. .

However, Dongshan girl just felt that what Zhang Fan said was very lofty. She has been on the operating table of countless experts, none of which made her feel that the operation can be done so easily, and it can make people feel tall.

Especially when encountering some doctors with poor techniques, a single measurement, to be honest, almost becomes the target of an eye-to-eye missile.

With one eye closed, she bent down and aimed at one of the patient's legs. To be honest, sometimes she felt unreliable, but although Zhang Fan didn't measure it, she just made her think it was reliable.

Perhaps this is a woman's sixth sense.

The prosthesis of the hip joint is like a pistol or the upper end of the leg bone that everyone usually gnaws on.

When installing this thing, first put the prepared bone cement into the expanded medullary cavity, and then insert and fix it, so that the prosthesis and the bone are permanently bonded together.

Bone cement is not the kind of cement that is usually used to build houses. The bone cement used in the operating room solidifies very quickly, and it takes seven to eight minutes to form and solidify. If it is slower, the prosthesis will not fit well.

So, when Dongshan girl was about to prepare bone cement, Dr. Wang was still in a daze with an obsessive expression on his face.

"Hehe, what's the matter, have you figured it out? It's very simple."

Zhang Fan asked with a smile like a devil.

"No!" Dr. Wang returned to his soul, and then asked in a very urgent tone.

When Zhang Fan was talking and doing it, he could see that Zhang Fan was not talking nonsense, he really improved the operation!

And the doctors in the electronic classroom have good eyesight. As Zhang Fan's surgery continues, they can also see that Zhang Fan has improved the operation method of the hip joint.

Finally, Dr. Wang asked the question in everyone's mind, and the question that everyone was very concerned about, "How did you do it?"

Dr. Wang looked at Zhang Fan longingly, just like a little doll looking at other girls holding popsicles but he didn't, looking longingly at Zhang Fan.

All I have to say is: can you give me a word?
