The superficial/deep tendon of the flexor, tendon of the flexor longus, and median nerve, which is located in the most superficial layer of the carpal tunnel, issue from the distal end of the carpal tunnel to the dorsal branch and innervate the thenar muscles, are housed in the carpal tunnel.
Carpal Tunnel Syndrome (CTS) is a syndrome caused by the median nerve being catarrhally compressed and denatured within the carpal tunnel due to exogenous stress, carpal tunnel stenosis, increased carpal tunnel contents, and the like. The main manifestations include pain in the wrist, dysesthesia and loss in the median innervation area, and atrophy of the thenar muscles. Carpal tunnel syndrome is the most common clinical nerve entrapment syndrome, which is mostly seen in 30-60 years old, and women are obviously more than men.
The carpal tunnel syndrome has a plurality of treatment methods, and the conservative treatment such as brake rest, brace fixation, oral non-steroidal anti-inflammatory pain-fighting medicine can relieve symptoms, but has poor long-term curative effect. Release of the transverse carpal ligament by arthroscopy is prone to median nerve and branch damage. The traditional open surgery has large incision, long recovery time and obvious incision scar.
