What are the five manifestations of hand nerve injury? What are the treatments for nerve injuries in

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.

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.

At first, I didn't feel anything, I couldn't feel my hands, my sense of touch was gone, and after a while I started to have severe pain.

If the pain is called peripheral neuralgia, the pain can occur for a long time, memory pain, also known as phantom limb pain, the broken nerve must be connected and anastomosed to create conditions for nerve recovery, but can not restore the nerve, the nerve anastomosis after the nerve anastomosis collapses into a new nerve implicit endplate, the key to the recovery of nerve function is whether the nerve fiber and the hail head cell of the nerve can regenerate through the nerve endplate, such as the nerve can not be excited and weak after anastomosis to pass through the nerve endplate, which is both a failure of the operation, of course, there is no hope for recovery. In addition to neurotrophic drugs, traditional Chinese medicine can be used to enhance and improve local blood circulation for nerve injury. Softens the scar, prevents adhesions, improves microcirculation blood supply, and uses nerve regeneration drugs to stimulate and activate postoperative nerve cells to cross the nerve anastomosis endplate to innervate the function of the lower limbs and recover.
