Carpal tunnel syndrome is a very common disease, mainly related to occupations in which hand movements are the main focus. With this disease there will be gradual numbness, burning pain, inflexible hand movements, weakness and other symptoms. At night, the pain will intensify, and some patients may even wake up from their dreams in pain, and if it is ignored for a long time, it may lead to nerve damage, hand deformity or even necrosis. Once you have carpal tunnel syndrome, there is no need to be overly nervous. For patients with mild symptoms in the early stage, conservative treatment can be taken to restrict the movement of the wrist joint to promote the decreasing of edema in the carpal tunnel, or local closure treatment with prednisolone acetate can be used. The principle of surgery is to cut the transverse carpal ligament and the outer membrane of the median nerve to decompress the median nerve and relieve the discomfort. Traditional surgery is performed under the naked eye, which is more traumatic to the patient and can easily cause local adhesions and lead to recurrence of the disease.
