When the transverse carpal ligament thickens or the pressure in the carpal tunnel increases due to various reasons such as long-term activity and strain, it can compress the median nerve and cause a series of hand symptoms, including numbness in the thumb, index finger, middle finger and half of the ring finger, accompanied by hand muscle atrophy, a series of syndromes called carpal tunnel syndrome, also known as carpal tunnel. Carpal tunnel is also known as carpal tunnel syndrome, commonly known as mouse hand. The median nerve in the hand passes through the wrist, making a specific track in the wrist called the carpal tunnel. The posterior part of the carpal tunnel is a bony channel consisting of the lunar and navicular bones and other carpal bones, preceded by a plagiocephalic transverse carpal ligament, and the tunnel contains the median nerve and the nine tendons that innervate the fingers.
