What are the treatments for nerve injuries in the hand?

a). In principle, the sooner the nerve injury is repaired, the better the functional recovery. As long as the nerve damage is mild, the broken end is neat, and there is no obvious defect; **Those with good coverage, light wound contamination, and no infection after debridement should be immediately sutured in the first stage.

The main method of hand nerve repair is nerve suture (including adventitial suture and peritoneal suture), in general, epineurial suture is used when the nerve trunk is injured, and peritoneal suture should be used when the nerve sensory and motor branches can be separated. If there is tension during nerve suturing, the two nerve disconnects can be appropriately discontinued, the position of the joint can be changed (e.g., flexion of the wrist joint when suturing the median nerve), and nerve displacement can be done (e.g., the ulnar nerve is ruptured after the elbow, the ulnar nerve is moved to the front of the elbow, and the nerve is sutured in the elbow flexion position). At this time, the ulnar nerve should not be sutured in situ behind the elbow, and the elbow joint should be fixed in the straight position for a long time, which will affect the functional recovery of the elbow joint).

Even if the nerve defect is too large to be sutured directly, as long as the local soft tissue conditions are good, primary nerve transplantation can be performed. In order to avoid sensory loss caused by the incision of the donor nerve, the distal severed end of the incision nerve can be sutured to the adjacent normal nerve trunk by end-to-side anastomosis, and the lateral branches of the normal nerve trunk germinate, and the regenerated nerve fibers grow in and restore its sensory function.

If the nerve is partially damaged, the uninjured part should be carefully separated and protected, and the injured part should be debrided and sutured.

After surgery, the affected limb should be properly fixed with a plaster pad to keep the sutured nerve in the relaxed position to facilitate its healing. The fixation time is generally 4 to 6 weeks depending on the amount of tension at the time of its suture. Antimicrobials are used appropriately to prevent infection, and neurotrophic drugs are used appropriately to promote nerve regeneration.

After removal and fixation, functional exercises should be carried out as much as possible, supplemented by physical **. Functional exercises and local physical** play a role in promoting nerve regeneration and preventing muscle atrophy.

It is important to restore the function of the nervous system to the opponent. Special care should be taken to protect the injured limb from burns or frostbite until hand sensation has recovered, which can be difficult to heal if it occurs. Hyperesthesia is usually present in the early stages of sensory recovery, and over time the regenerated nerves mature, and the hyperesthesia phenomenon will gradually disappear.

ii) Prognosis. The effect after sensory nerve anastomosis is acceptable, but the effect after motor nerve anastomosis is not good.

Once the interruption of nerve continuity is confirmed in traumatic hand nerve injury, the sooner the repair is made, the better the functional recovery. Direct end-to-end sutures are indicated if the nerve is severed and there is no defect, and nerve grafting is generally indicated if the nerve is defective due to severe contamination or old damage. Currently, for small digital nerve defects, nerve sheath bridging can be used to avoid nerve transplantation.

After the nerve is sutured, a cast is required for about 4 weeks.

If the continuity of the nerve exists, it can be conservative for a period of time, and depending on the recovery of the nerve, it is decided whether to continue to be conservative**, or to perform nerve exploration and release surgery.

For entrapment nerve injury, it is necessary to distinguish between compression caused by pathological factors (eg, local mass) and physiological factors (ligament) compression, and if the former, prompt surgery** is required to remove pathological factors and release the nerve; If the latter is the case, it can be conservative for a period of time, and if conservative is ineffective, surgery can be performed to release the nerve.

It is important to note that there is a certain degree of uncertainty about the effect of nerve injury, because even if the doctor performs a good nerve suture or nerve release, whether the nerve can fully recover depends on the growth of the nerve and the atrophy of the target muscle of the hand.

Nerve damage may be due to nerve rupture caused by trauma, nerve damage caused by compression, or nerve damage caused by immune, poisoning, metabolism and other suspected factors. Mainly includes medications** and surgery**.

1. Drugs**:

For example, for nerve damage caused by immune, poisoning, metabolism and other factors, immunosuppressants such as glucocorticoids, antidotes and other drugs can be used in the case of identification. In addition to the drug for the cause of the disease, drugs such as vitamin B1 and vitamin B12 can also be used to nurture the nerves. For nerve rupture or nerve edema caused by compression of eggplant choppel, dehydrating drugs such as mannitol and sodium escin can also be used.

2. Surgery**

If the lumbar spine compresses the nerve due to the fracture, it is necessary to reduce the fracture site, remove the fracture fragment, and surgically relieve the compression of the nerve. If there is an open injury that causes a nerve tear, the nerve fibers should be quickly anastomosed to ensure nerve continuity.

When nerve damage occurs, you should see a doctor in time to identify the cause of the nerve damage and do it under the guidance of a doctor**.

If the finger nerve is damaged, it depends on the severity of the problem, whether it is necessary**, listen to the doctor. Alternatively, you can also take some supplements to help you recover. You can try the health care products of NMN, which can improve motor nerve function, it is recommended that you can eat and see the probiotic NMN, I have been eating.

You can speed up to find out.

This is caused by nerve damage caused by hand trauma, the hand can not be opened, you can use local hot compress with oral nutrition nerve drugs**, you can also acupuncture massage, slowly can**,

Surgical anastomosis or release of adhesions of broken or damaged nerves only creates conditions for nerve recovery, but can not restore nerves, (the reason why nerves cannot be restored is that new endplates or scars will form at the place where the nerve anastomosis occurs after nerve anastomosis), the key to the recovery of nerve function is whether nerve fibers and nerve cells can regenerate through this nerve scar or endplate, such as after anastomosis the nerve can not be excited and weak to pass through this nerve endplate, which is both a failure of surgery and of course no hope for recovery. No information can only be provided for you to provide a theoretical **plan,** to recover the disease, it is necessary to use traditional Chinese medicine to enhance the local blood circulation of nerve injury. Soften the scar, prevent adhesions, improve the blood supply of microcirculation, and cooperate with the nerve regeneration pill to stimulate and activate the postoperative nerve to cross the nerve anastomosis endplate to obtain regeneration, so as to innervate various functions of the limb as soon as possible**.

The key to recovery lies in the early stage. If you need guidance, please send a detailed medical record, and electromyography will guide you (from the **time, you have passed the **period, and whether you can get further recovery through ** depends on the condition).

Hello, nerve damage is indeed very slow in recovery, need to recover little by little, may take a few years or longer, during the recovery period must be confident that massage and acupuncture can be used for **, in addition to adhere to ** training, step by step.

Nerves refer to all nerves except the brain and spinal cord, including ganglia, nerve trunks, plexuses, and nerve terminal devices, which are distributed throughout the body. In general, early injuries are recommended for surgery**, and drugs to protect blood vessels and nutrition nerves should be used; middle and late stage injury, massage, massage training, massage, massage training, sensory training; During the whole process, attention should be paid to the safety protection of the affected limb, to prevent scalding and crushing, and to keep warm.

The main thing is to do some functional exercises The most important thing after finger nerve injury surgery is functional exercise You have been working for so long The best effect of exercising now is to maintain the status quo No more muscle atrophy may you be soon**.

Clause. 1. After the nervous system of the hand is damaged, the flexion and extension muscles of the wrist and fingers and their innervated nerves will be affected, especially the median nerve, and the injury to the ulnar nerve is the most important to pay attention to. Therefore, wrist and finger flexion and extension are the most important things to pay attention to.

Clause. Second, the patient's median nerve damage is manifested as thumb and index finger, there is an obvious phenomenon in terms of dysfunction, the sensory dysfunction of the fingers and semi-palmar surface will be affected, the main manifestation is sensory loss, some patients are gradually disappearing, and some patients are completely gone, which proves that the severity of the patient's joint injury should be controlled as soon as possible to avoid the aggravation of finger joint injury.

Clause. 3. After the nerve of the palm and finger parts of the finger joint is damaged, the sensory dysfunction of the two fingers adjacent to each other or the sensory dysfunction of one side of the finger is the most obvious. According to the phenomenon of nerve damage in the patient's fingers, the severity of joint injury can be effectively controlled and the problems caused by joint injury can be avoided.

Clause. Fourth, the patient's radial nerve site will also have problems, manifested as sensory impairment on the radial side of the dorsum of the hand and the proximal interphalangeal joint on the proximal side of the three and a half fingers, and the sensory function of the patient's tiger mouth will be reduced and completely lost. The impaired function of the finger can be prevented based on the actual presentation and complications.

The problem of nerve damage in the finger part has been briefly introduced, the patient will have a lot of complications after the occurrence of the disease, when the adjacent disease and related parts have problems, it should be controlled as soon as possible, the finger muscles and the important parts of the innervation of the nerves, when the patient's nervous system has obvious sensory impairment, it needs to be adjusted as soon as possible.

The human hand is mainly innervated by the ulnar nerve, median nerve and radial nerve, of which the radial nerve is a single sensory nerve, and after the radial nerve injury, the radial nerve in the hand is mainly manifested as semi-numbness on the radial side of the back of the hand, or loss of sensation, and the deformity of the vertical wrist. Median nerve injury manifests as hypoesthesia in the three half-fingers on the radial side of the palm, thenar atrophy, thumb adduction weakness, and thumb-to-palm weakness. Ulnar nerve injury, manifested by decreased sensation in one and a half fingers of the ulnar border of the palm, thenar atrophy, semi-numbness of the ulnar side of the dorsum of the hand, inability to adduct the thumb, and claw-shaped hand.
