What is carpal tunnel syndrome? Carpal tunnel syndrome, also known as “mouse hand” and “keyboard wrist”, is a series of syndromes that cause sensory and motor dysfunction in the median nerve distribution area below the wrist due to increased pressure in the carpal tunnel and compression of the median nerve for various reasons. In layman’s terms, this means that the median nerve, which leads from the arm to the fingers, is compressed at the wrist. The clinical manifestations of carpal tunnel syndrome generally start with pain, numbness and other sensory abnormalities in the radial side (thumb side) of the three and a half fingers, with the progress of the disease may appear motor dysfunction, such as grasping, gripping, rubbing, twisting and other movements with great effort, inflexible movements, typical cases can be manifested as ape palm, and in the late stage of atrophy of the interphalangeal muscle. It is the most common type of peripheral nerve entrapment syndrome. Treatment of carpal tunnel syndrome Patients with early mild cases will generally receive conservative treatment, including taking some nerve-nourishing drugs, plaster fixation or ultrasonic treatment, etc.; for more serious patients, under the advice of doctors, surgical treatment may be required, including various incisional surgeries, small incision decompression and endoscopic surgery, etc. The purpose of surgery is to release the median nerve, and incisional release decompression is best performed under a tourniquet to reduce or avoid causing damage to one or even several bundles of median nerves. For muscle atrophy that is already severe enough to occur, even if surgical treatment is performed, the muscle function can only be partially restored.
