Nerve damage to the finger cannot recover on its own. Patients should receive prompt treatment in neurology to restore finger function as much as possible. When a nerve is damaged, it may cause the death of nerve cells, which are permanent cells that do not regenerate after necrosis and only compensate by producing synaptic connections through other adjacent cells. If the nerve damage is mild, with only a mild tear of the nerve surface fibers, and the ability to repair itself is strong, after timely treatment, it can usually be restored to normal and does not affect the normal function of the finger. If the patient has severe finger nerve injury, most of them cannot return to normal and can affect the function of the fingers. When the finger nerve injury, if the injury is mild, should be as soon as possible to clear the wound suture, strengthen the incision anti-infection treatment. If the injury is severe, nerve end replantation should be performed in a timely manner.
