Nerve damage to the finger, which normally only recovers a small percentage on its own, should be treated aggressively by the patient to help and promote recovery of finger function. Nerve cells are permanent cells and do not regenerate after damage and necrosis. If the nerve injury is mild, with only a mild tear of the nerve surface fibers, and the ability to repair itself is strong, through early surgical treatment and subsequent rehabilitation, it may return to a basic normal state, and is not a major obstacle to life. However, if the nerve damage is more serious, such as nerve rupture, often may cause permanent damage, can not be repaired to a normal state, can affect the function of the finger. When a nerve injury to the finger occurs, the patient should be cleared and sutured as soon as possible, strengthen the wound anti-infection treatment, and it is recommended to promptly consult the hand and foot surgery, and the doctor will determine the specific treatment plan.
