Although it was just a simple sentence about work assignment, Li Jiahong once again affirmed Wang Chen's level.

Because the level of a doctor can be seen from the first time he meets the patient, because after seeing a patient's condition, the first thing a doctor usually considers is what the patient is like.

Which treatment plan is the best.

Now, the first thing this patient needs to do is to reset his condition.

Patients mainly suffer from dislocation between the metacarpophalangeal joints and fractures of the phalanges.

After all, Li Jiahong is the leader in the field of hand and foot trauma in Shandong Province, and he is very good at treating this kind of joints.

Under normal circumstances, if the fracture of the phalanx is not displaced, it is mainly reduced by manual reduction.

An open fracture like this patient requires incision and internal fixation, such as Li Jiahong's Kirschner wire fixation at this time. This method is strong, reliable and commonly used clinically.

Fixation surgery for open fractures of the phalanges is a frequently required surgery in hand surgery. Li Jiahong has been doing this kind of surgery for half his life. He has rich experience and is very skilled in technique.

Therefore, Li Jiahong is quite confident in this aspect.

Even Wang Chen had to admit that Jiang Hao was very old, and Director Li did a really good job with the phalangeal surgery!

The treatment of phalangeal fractures requires not only accurate reduction and firm fixation, but also functional exercises as early as possible to restore the flexible movement of the fingers.

The most important thing that affects the surgical effect is accurate reduction and firm fixation.

The fracture surgery ended quickly, and Li Jiahong couldn't help but breathe a sigh of relief.

Wang Chen said with a smile: "Director Li did a really good job with the surgery on the broken phalanges. I saw it before at the annual meeting. I didn't expect you to be even more powerful now than before!"

Has Wang Chen attended the annual meeting of hand and foot trauma before? No, then why do you say this? It’s just business flattery. Today, Wang Chen has become a bit of a philistine.

When Li Jiahong heard what Wang Chen said, he smiled happily, and then said seriously: "Dr. Wang, the rest will be left to you."

Wang Chen nodded, the next work is the top priority.

The orthopedic surgery only takes ten minutes and does not affect the nerves and blood vessels of the hand.

Li Jiahong looked at the back of the little boy's hand with a worried look. Even though the back of his hand had been debrided, it still looked terrible.

Both the ulnar artery and the radial artery have been completely ruptured. According to effective clinical data, the survival rate of the hand of injured patients with complete rupture of the ulnar artery and radial artery can only reach about one-third.

One-third means that two-thirds of the cases fail, so this little boy's hands are really worrying...

In order to stop the bleeding, the artery has been ligated before the operation. All that needs to be done now is to anastomose the damaged blood vessels.

This is also due to the rupture of the artery in the hand. If it had been elsewhere, the chance of recovery might not be even one-tenth.

Because the blood supply of the hand is extremely rich, the main sources are the radial artery and the ulnar artery, in addition to the anterior interosseous artery and the posterior interosseous artery.

Of course, there are also people with amazing bones. For a small number of people, the median artery can also supply blood to their hands. I just don’t know if such people are martial arts prodigies and can they practice the Tathagata Palm?

The blood vessels of the hand form a smooth traffic channel in the form of arterial mesh or arterial arch, and provide blood to various areas of the hand to ensure that the hand can complete, hold, grasp, hold a variety of functions.

It is precisely because the above blood vessels are rich in each other and have good compensation capabilities that the hand can have more than 30 % of the opportunity to recover even if the radial artery and ulnal artery are broken.

Wang Chen picked up a needle with a needle and was carefully prepared to start suture. The blood vessels were fortunate to say that the nerves need to be sutured. Therefore, hand surgery is generally called micro -surgery.

Generally speaking, the multiple of the microscope is OK from 6 to 10 times. Wang Chen is used to using an eight -fold mirror.

This multiples are operated with the field of vision.

Wang Chen's operation is very delicate and exquisite.

Li Jiahong on the side, watched the operation seriously.

He felt that Wang Chen's operation seemed to be light weightlifting, because he sutured the surrounding small blood vessels and the gap of large arteries to give people the same, which was a bit powerful ...

The radial artery is sutured, and then the ulnar artery, as well as the surrounding small blood vessels, such as the back side arteries of the bone ...

This is too fast, Li Jiahong is a little dumbfounded. Is this sutured surrounding blood vessels? How can it be faster than the intestinal tube ...

It didn't take long for the blood vessel suture to complete it.

Li Jiahong quickly loosen the ligated arteries and test blood!

Looking at the fingertips, I couldn't help laughing and said, "Perfect!"

Wang Chen smiled and said nothing, and then began to suture the nerves.

The difficulty of suture of the nerves is even greater than the blood vessels.

Generally speaking, the injury of the hand nerves must be repaired in principle, the better the function recovery.

Therefore, when Li Jiahong was in the provincial hospital, he was so anxious to send the patient. He was worried that the longer the delay, the worse the patient's nervous recovery.

The main method of hand nerve repair is also suture, including externally suture and suture of the beam membrane.

When neurotransmitters are damaged, it is generally only necessary to suture the outer outer membrane.

In the nervous sensation, the exercise branch can be sutured with a beam film when separated.

It is to separate the nerves, the shallow branch, and then suture the beam film separately.

However, when Wang Chen pulled the nerve to prepare for suture, he suddenly felt that there was tension, which showed that the length of the nerve was not enough.

This is no wonder, because the patient is worn, not cutting the injury.

Li Jiahong naturally found this problem. He frowned and looked at Wang Chen and asked: "Doctor Xiao Wang, isn't it long enough? Do you want nervous transplantation?"

Wang Chen thought about it for a moment, then shook his head and said, "Now the tension is relatively large, I try to relax the joint position, will it improve?"

Li Jiahong looked at the disconnected nerves and was a little worried, saying, "I'm worried that even if it is loosened, it may not be enough!"

However, if the nerve transplantation is certainly not as good as the direct stitching of this, and the nerves in other areas are transplanted, it can easily cause the lack of nervousness after the supply area.

It is equivalent to dismantling the east wall to make up the West Wall. This is just a last resort. However, Wang Chen is unwilling to destroy the original nervous veins.

Wang Chen began to be careful to leave the two nerve breaks, and then changed the position of the joints to make nerve movement.

After some operations, Wang Chen found that the nerves at both ends did grow longer, how much is it? 1 mm!

Seeing this situation, Li Jiahong was embarrassed, because with these 1 mm, the two breaks of the nerves became a state of not next to each other.

May be able to sew.

Li Jiahong was silent because he didn't know what to do.
Chapter completed!
