The carpal tunnel is a tough, inelastic, fibrous sheath of bone covered by the carpal bone and the transverse carpal ligament above it into a bone-fiber tunnel in which the median nerve travels. Carpal tunnel syndrome (CTS): commonly known as mouse hand, is a syndrome in which the median nerve is compressed in the carpal tunnel, causing pain and numbness in the area it innervates. Common causes (1) Mechanical factors: wrist fracture, dislocation; long-term excessive force use of the wrist, and improper sleep posture, etc., which increase the pressure in the carpal tunnel, as well as tendon sheath cysts, gout and other diseases that cause compression of the median nerve. (2) Inflammatory factors: tenosynovitis, bursitis, etc., resulting in inflammatory exudation, tissue damage in the carpal tunnel, increased pressure in the carpal tunnel, and widespread adhesions resulting in restricted movement. (3) Endocrine factors: obesity, diabetes, pregnancy, lactation, menopause and other endocrine metabolic disorders. According to research findings, heavy computer users (up to 7 hours), the risk of mouse hand up to 87%, common population: middle-aged and elderly, now increasingly young, the incidence of women is about three times that of men, can be a side or bilateral onset, the tendency is often engaged in grasping, rubbing, long-term excessive force use of the wrist, such as carpenters, chefs, computer users, gamers; suffering from gout, diabetes, hypothyroidism, rheumatoid arthritis It can occur on one or both sides of the wrist, such as woodworkers, chefs, computer users, gamers, etc.; people suffering from gout, diabetes, hypothyroidism, rheumatoid arthritis, and women during pregnancy and lactation.
