What are the chances of a successful replantation after the guy saws off his thumb?

Recently, a young man in Xi'an was working with a chainsaw, and his left thumb was accidentally cut off, but fortunately, after timely surgery by doctors, his thumb has been successfully "replanted".

Usually the first finger of the finger is the thumb, the thickest and shortest finger, which helps us hold things. Compared with apes, the human hand has evolved a thumb that the ape hand cannot compare, and the human thumb is far more flexible and powerful than the ape, so that humans have the ability to grasp accurately and eventually develop the ability to use tools. <

The thumb can also reflect the state of brain activity, when a baby is born, its thumb is atrophied in the palm of the hand, and when its intelligence is gradually developed, the thumb's ability to stretch and move is gradually enhanced, but when a person is about to die, the thumb will atrophy and weaken, and fall into the palm, indicating that the brain activity will be terminated. <>

In fact, the chance of successful replantation of the severed finger in the short term is very high, after the finger and other limbs are severed, although the blood nourishment is lost, it still has vitality in the short term, and after a long time, it will be degenerated and rotted. In addition, the observation and care after finger replantation are very important, which is an important part of the success of finger replantation. Moreover, if the finger can be delivered to the hospital in time within 4 to 6 hours, and the severed finger can be better preserved, the patient should have a positive psychological preparation and face the risks in the operation correctly.

However, the success of the operation is realistic. It is advisable to stay in the hospital for a week after the surgery in case of an emergency. <

However, the success rate of amputated limb replantation has a lot to do with the cause of the patient's injury, the retention of the severed finger, and the degree of injury.

Moreover, simple finger amputation replantation surgery, which has developed very maturely after decades of development, is currently a very mature operation in China, if it is an injury caused by sharp cutting, the success rate of replantation is actually very large. However, after that, you should do a good job of caring for the wound, pay attention to cold and keep warm, do not smoke and drink, and carry out regular work under the guidance of a doctor**. 。

Personally, I think the chance of successful finger reimplantation is about 80%, because the first one is very difficult to match, and the second one requires such an operation during a special period, so the risk is still relatively large.

The chances of success of finger replantation depend on time. If the broken finger is reconnected after two to four hours, there is an 80% chance of success here. Because the cells in the fingers are still energetic, the blood can still circulate when connected.

More than 80%, now the domestic medical level has improved, finger replantation is not a major surgery, its success rate has been as high as more than 80%, but after the injury, the finger should be dealt with in time, stored in a frozen environment and quickly seek medical treatment, only in this way can the success rate of surgery be improved.

Finger replantation is now a well-established technology. The success rate is only a statistic, and it is not of great practical significance for replanting. This depends on many factors, such as the mechanism of the injury, the skill of the surgeon, and the patient's ability to cooperate.

Your description should not be completely off-top. There should also be some blood vessels. This increases the chances of a successful operation.

It depends on the time of injury and the part of the injury. The shorter the time between injury and surgery, the higher the probability of success. The closer the injured area is to the end of the finger, the lower the probability of success.

[Grade 7 work-related injury] standard: 16) A thumb interphalangeal joint is severed;

17) Deformity of the interphalangeal joint of one thumb, complete loss of function;

18) In one hand, except for the thumb, the proximal interphalangeal joints of the other 2 3 fingers (including the index finger) are severed;

19) Loss of function of the proximal interphalangeal joints of 2 3 fingers (including index finger) except for the thumb of one hand;

Work-related injury grade 8] standard: 16) One hand, except for the thumb and index finger, the proximal interphalangeal joint of two fingers is severed;

17) In one hand, except for the thumb and index finger, there are two proximal interphalangeal joints that are non-functional;

Work-related injury grade 9] standard: 16) 1 2 missing part of the distal part of the thumb;

17) 2 3 segments of the index finger of one hand are missing; 18) loss of function of the interphalangeal joints of the thumb;

23) Patients without functional impairment after fracture internal fixation;

If it is eligible to replant the severed finger, but it has certain requirements, one is the degree of damage, such as a sharp wound, knife wound or cutter cut, the damage of the long Li is not serious and can be replanted, if the bone has been crushed due to the pressure of some heavier objects, then this part is not replantable bending resistance, in addition to local injury, if the time limit is too long, distal ischemia and necrosis is too long, then it is not possible to replant the severed finger at this time. But if you don't get it back at that time, you can also do finger reconstruction to restore your finger. [Click on manual consultation to learn more**plan].

According to Shunde Peace Surgery Hospital, finger reconstruction refers to the 1:1 restoration of the missing finger through 3D printing technology, and then accurately taken from different parts of the patient's body according to the 3D model, and finally transplanted to the hand, so as to restore the shape, function and feeling of the finger.

If you want to know more about the finger Zailing Tomb, it is recommended to consult Shunde Peace Surgery Hospital. Shunde Peace Surgery Hospital has been focusing on the research of hand surgery, and has rich clinical experience in finger replantation, finger reconstruction, and various complex hand trauma.

The severed finger can also be replanted. In the event of an accident, if there is a severed limb during the first aid process of the wounded, it needs to be properly stored and transported to the hospital with the injured person, so that the doctor can replant the severed limb and fingers. After protecting a severed limb or severed finger, it should be stored for first aid.

In general, most severed fingers can still be replanted.

1. Replantation:

Generally, it refers to the surgery to restore part of the function of the original finger after re-anastomosis of the bone, blood vessels, nerves, tendons, and ** within 8 hours.

2. Reconstruction: To put it simply, it is to reconstruct a normal finger through surgery. Finger reconstruction has undergone flap reconstruction, toe grafting, and now holomorphic reconstruction. The difference is that the flap reconstruction has no function, but simply wraps the injured finger; Toe transplantation is to take a toe from the foot and attach it to the injured hand by transplantation; Holomorphic reconstruction is a new technology extended and developed on the basis of toe transplantation, before transplantation through the modification (bone, nail flap), so that it is close to the same appearance as the normal finger, the shape of the phalanges is the same, and at the same time through the microscope anastomosis blood vessels, nerves, tendons, K-wire fixation of the bone connection site, after the later stage of the first exercise so that the reconstructed fingers can have normal grasp, sensation and perception.

Because the difficulty of holomorphic finger reconstruction is very different from that of ordinary toe transplantation, reconstruction is different from other surgeries, the difference is thousands of miles, and the whole process is operated under the microscope, so the operation time is generally more than ten hours, and there are fewer hospitals and experts who have mastered this kind of technology, and a suture mistake will lead to the failure of the entire operation.

How long have you been cutting off your finger, if it is too long, the finger is necrotic and cannot be connected, you can repair it with skin graft surgery, Chengdu Microscopic Hand and Foot Surgery Hospital can do it.

When using something as dangerous as a chainsaw, be cautious and don't get distracted by other things or talk to others, as you may become disabled. We all know that chainsaws are dangerous, but sometimes we have to use them when cutting some hard things. Mr. Tang is one of those who often needs to use a chainsaw to carry out his work, which happened on March 21 when Mr. Tang accidentally cut off one of his fingers with a chainsaw.

After this incident, Mr. Tang rushed to the hospital to try to save his finger.

The doctors at the hospital operated on Mr. Tang, and due to the relatively good preservation of the severed finger and the timely treatment of Mr. Tang, coupled with the doctor's very good skills, Mr. Tang's fingers finally succeeded in recovering his palm, and after the fingers were connected, it looked no different from before the severed fingers, and it is believed that Mr. Tang will be able to return to his job soon. I also hope that Mr. Tang will be more careful when working in the future, because his work is more dangerous, and if he is so careless next time, he may see off other fingers. Mr. Tang's work is also something that ordinary people dare not do, after all, some people feel very scared when they pick up a chainsaw.

And Mr. Tang should also thank the doctors who operated on him, if it weren't for these doctors, Mr. Tang might never have been able to return to normal life. So a good doctor is very important, and sometimes a good doctor can save a patient's doctor. I believe that doctors are benevolent, and doctors will do their best to help every patient and make their bodies healthy.

It can be said that being a doctor is a very great profession and a very special profession. In the past, it was almost unimaginable to attach a severed finger back to the patient's palm, but with the development of the times, such a thing has become very commonplace. We also want to be grateful for the current era, which allows us to live a healthy and happy life without worrying about various diseases.

If we accidentally cut off our finger while using a chainsaw, be sure to bring our finger with us to the doctor and keep the broken finger safe.

If the severed finger is not preserved, it may die even if it is connected. And after the finger is broken, we should immediately seek medical attention, and if we delay for one more minute, there will be more possibility that our finger will not be connected. But if the finger is not connected, we should not blame the doctor, because the doctor did his best to save the patient's finger.

Pay attention to safety, take care of your body, etc. Pay attention to safety and avoid causing harm to the body; Take care of your body and don't take it personally.

When the finger is broken, you can take the original finger to the hospital within three hours to take the joint, and the tooth can also be broken in this way, at this time the most important thing is to rush time.

We must be cautious in life, in the event of an accidental injury, the current medical technology can realize the reconnection of the severed finger, and we must seek medical attention in time to avoid tissue necrosis.

, Lu Fanghua, an authoritative professor of Changsha annual ring orthopedics, will help you solve it.

The nature of finger amputation.

The severed finger must have a certain integrity, such as multiple fractures and severe contusions, or even vascular and nerve extraction, even if the anastomotic blood vessel is replanted, it is unlikely to survive.

The plane of the severed finger.

The distal interphalangeal joint is far away from the fracture, because the blood vessels are thin and the anatomy is not constant, some have no veins for anastomosis, and it is difficult to replant, and the survival rate is lower than that of the mesial segment.

Finger out of vivo time.

Finger replantation is time-bound. Generally, degeneration often occurs after 6-8 hours of separation in summer, and it is easy to die after replanting.

Preservation of ex vivo fingers.

It must be dried and refrigerated, such as soaking the severed finger in alcohol, new Jieer, normal saline, ice water and other liquids, it will affect the survival rate of replantation and even lose the conditions for replantation.

Age factor.

Children do not cooperate, and the blood vessel walls of the elderly have varying degrees of hardening, and the survival rate of replantation is low.

The viscosity of the patient's blood.

Different people have different blood viscosity, for patients with high viscosity, despite the application of vasodilators, the postoperative blood is still easy to form thrombus at the anastomosis to block the blood vessels, such patients often need to be re-explored after surgery, which greatly reduces the survival rate of the fingers.

Patient's mood.

Sudden accidents cause severed and damaged fingers (limbs), which brings unbearable psychological trauma to patients. Self-injurious patients often have low self-esteem, remorse, pessimism and disappointment, and depressed mood, all of which can easily lead to intermittent or even intractable spasm of posterior arterioles, so that replantation is ischemia and fails.

Active cooperation of the patient.

The patient's cooperation includes absolute bed rest during the risk period (within 10 days), immobilization of the affected limb, good mood, local and general warmth, persistent, active and passive smoking is strictly prohibited, etc., without the active cooperation of the patient, no matter how successful it is, it is often lost.

Can be replanted. But it also depends on how well your fingers are saved. According to experts from Shandong Hand and Foot Surgery Hospital, finger amputation and replantation are for injured hands, but the operation is not suitable for all cases of finger amputation, so the following aspects should be weighed before the operation

1. If the physical condition allows, under special circumstances, replantation should be considered after the general condition of Changwu is stable. 2. Replantation refers to the body must have a certain integrity and have repairable tissues and organs. 3. The isolated tissues of the severed finger have not been degenerated, and it is generally believed that the total ischemia time should not exceed 24 hours at room temperature.

Preservation of fingers: Proper preservation of severed fingers slows tissue degeneration and prolongs the time limit for replantation. The correct storage method is to use sterile wet gauze, dry gauze to wrap it successively, put it in a non-porous plastic bag, and place it in a 4-degree refrigerator sedan car.

Try to avoid being away from the end of the finger body"Febrile ischemia"State. It has also been reported that the severed finger was directly soaked in alcohol, disinfectant, etc., and the replantation was successful.
