The hand is broken, the limb is amputated, can it grow up?

At present, it is generally considered that it is not possible, nerves and muscles are non-renewable tissues, and the broken end is filled with connective tissue to form a scar, which cannot perform the normal function of the hand.

However, each cell of the human being has a full set of genetic material, which is only specifically expressed in order to carry out the function of the cell, so it is not completely impossible to regenerate, but the current scientific and technological capabilities should not be reached.

It can't grow out at the moment.

The ability to regenerate is related to the totipotency of cells, only the liver and bone marrow have a strong ability to regenerate, **, but the regenerated scar tissue, so it is not strange that the tissue regenerates, and the fingers obviously cannot be regenerated.

1. Replantation: Generally speaking, within 8 hours, the completely severed or incomplete severed finger body is reconstructed to restore part of the function of the original finger after re-anastomosis of bone, blood vessels, nerves, tendons, and **.

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.

It's time for amputation, so I can only face it calmly.

Amputation surgery is generally necessary to improve the preoperative preparation, if there is shock, the shock should be corrected first, and the surgical method is to make a ** annular incision near the lowest position of the wound for the wound that has been infected. For fresh and non-infected wounds or amputations due to serious vascular injury, half-shaped incisions can be used, the anterior and posterior flaps of the upper limbs are of equal length, the lower limbs are long in front and short in the back, the total length of the flap should be the same as the diameter of the limb, and the plantar flap should be turned upwards as much as possible. Circumferential incision of the deep fascia along the retracted skin margin, and circumferential incision of the muscle along the edge of the retracted deep fascia, preferably cutting off the superficial muscles first, allowing them to retract and then cutting off the deep muscles, so that the section is funnel-shaped.

After the muscle to be severed is retracted upward, the periosteum is cut in a ring at its edge, and the bone is sawn flat and sawn. Double ligation is performed on the large vascular application, and one of the filaments is ligated with a through-suture. After the tourniquet is released, all bleeding points are ligated one by one, and 1%-2% lidocaine should be applied for local closure of larger nerve trunks, and then cut with a sharp blade after pulling down 2-3 cm.

Nerve cuffs are generally not ligated, the wound is flushed with sterile isotonic saline, and then the wound is bandaged, and the wound is sutured.

The affected limb is abducted and placed flat on another small operating table. Place an inflatable tourniquet. Cut the blood vessels and nerves U3000 separates the ulnar, radial artery, median nerve, and ulnar nerve, and cuts it off after conventional treatment.

Note that the anatomical position of blood vessels and nerves will vary in different truncation planes. After rubber drainage, the deep fascia and skin flap were sutured, and finally compressed and bandaged. It is recommended to take psychological care of your friend at the same time as the operation, and generally the psychological trauma to the patient is greater in this case.

1. The problem of shock. Compound injuries are hemorrhagic shock in the early stages and septic shock in the later stages. The patient not only suffered double fractures of the tibia and fibula, but also had a great impact on the active respiratory function due to pulmonary contusion and multiple rib fractures, and at the same time, due to the post-injury decubitus position, it would cause falling pneumonia, and at the same time, most of the multiple injuries were high-energy, coupled with blood loss and greater traumatic factors, and the autoimmune function was low, which could easily cause nosocomial infection, including wound and aspiration pneumonia, causing the patient's death.

2. For the treatment of double fractures of tibia and fibula, the external fixator is correct, and it is recommended to use VSD continuous negative pressure drainage to keep the wound dry, and at the same time, local dryness can be reached due to negative pressure factors, which can promote the growth of local granulation tissue and lay the foundation for the second stage of treatment. We have treated patients with large areas of left thigh, and after three changes to VSD, local infection control and stage II treatment were performed. For surgeons, a very important measure to control infection is adequate and thorough drainage.

This antibiotic cannot be replaced.

3. It is to support**. Support is very important. It is important to avoid the exacerbation of the original infection and to repair the wound. Intravenous nutritional support may be given, protein may be given, etc. Of course, at this time, it can be combined with traditional Chinese medicine, and the effect is also very good.

It is very important to fully communicate with the doctor before the deadline, fully understand the risks and pros and cons of the surgery, understand the purpose of the surgery and possible situations, follow the doctor's instructions to prepare the patient, actively cooperate with the doctor to carry out the surgery smoothly, and understand the precautions after surgery.

In general, patients who have undergone amputation surgery should not only do a good job in the postoperative care of the patient, but also do a good job in the psychological counseling of the patient in a timely manner. After amputation, it will have a certain impact on the patient's life and work, and sometimes the patient will be more depressed and lose confidence, so at this time, we must do a good job in the patient's psychological work and encourage the patient to do the best exercise in time.

Listen to the doctor and save your life first. A prosthesis can replace some of the functions of a lost limb and allow you to regain some independence and ability to work. Be strong, brother!

If there is no way to save your life, you can install a prosthetic leg in the future and look like a normal person.

Follow the doctor's advice and save your life, but if you have suicidal thoughts, it is recommended to think about yourself and the people around you.

To stay alive.

Listen to the doctor's plan!

You can go to a big hospital for a check-up.

Ask your doctor or listen to professional advice. As for the life and work after surgery, you need to adjust it slowly by yourself.

But this kind of thing really doesn't mean to say it, and the average time allocated by all employed people is not the completion rate of the task of the conference center. A person at home is a heart, can't extricate himself is equal to what it is, and won't talk about me.

You should follow the doctor's advice, I'll consult about these effects again, what's going on?

Derek Steen had to amputate his left limb in a motorcycle accident, but he was able to feel the presence of that arm after the operation, but when he looked at it, there was nothing. It's like a vicious circle, he feels phantom limb pain so he looks at his arm, and the more he looks at it, the more pain he feels. What's even stranger is that when he starts shaving again after the surgery, he feels his phantom limb start stinging again when he shaves the left side of his face.

dr.Ramachandran found that when touching the left side of Derek's face with a swab, he could not only feel the swab on his face, but also feel the swab touching his non-existent arm, and even when the swab ran across his cheek, he could feel the "slashing" sensation on his face and his non-existent left limb. In fact, each limb of the human body has a corresponding part in the cortex of the brain.

The sensory cortex of the brain is like a map of the human body, but it is out of order. <>

Amputation [jié zhī].

Amputations are divided into minor amputations and major amputations. Minor amputation refers to the limited removal of part of the tissue through open partial amputation of part of the blood vessel or limb correction while removing the infected and necrotic tissue.

A major amputation is a condition in which a serious disease state cannot be alleviated by revascularization, medication control, or minor amputation. Major amputations are divided into low amputations, which are generally amputated 10 cm below the knee, and high amputations, which require amputation at the base of the thigh. After high amputation, the mortality rate is more than 50% within 2 years and more than 80% within 5 years.

The above survival rates are all survival rates for osteosarcoma, amputation due to bone cancer. The survival rate of amputation due to normal causes (such as accidents, car accidents, etc.) is basically the same as that of normal people.

The Chinese name is amputation.
