The recurrence rate after primary carpal tunnel release is approximately 2%. The success rate of surgery to relieve symptoms depends on the definition of “success” and the metrics applied. For example, with respect to alleviation of symptoms, up to 90% success is reported. Yet with respect to patient satisfaction, approximately 50% is reported.
Each year, doctors perform 400,000 to 600,000 carpal tunnel release surgeries — one type of surgery used to treat the condition — making this one of the most common upper-extremity procedures.
Carpal tunnel surgery has a clinical success rate of 75-90%. [26] Success is most frequently measured with the Boston Carpal Tunnel Questionnaire, physical examination (sensory function, motor function, pain, electrodiagnostic, trophic function), and patient self-assessments.
Carpal tunnel syndrome (CTS) is a nerve compression syndrome associated with the collected signs and symptoms of compression of the median nerve at the carpal tunnel in the wrist. Carpal tunnel syndrome usually has no known cause, but there are environmental and medical risk factors associated with the condition. [1] [6] CTS can affect both wrists.
The Chow device is a two-portal device, while the 3M Agee endoscopic carpal tunnel release system is a single-portal device. The Chow device was produced by Dyonics and early papers documented its success. It was heralded by its corporate manufacturer as a breakthrough in carpal tunnel surgery.
The development of carpal tunnel syndrome was of particular interest for other idiopathic tardy nerve palsies. Carpal tunnel served as a model for how nerves could be squeezed by narrow anatomic compartments and soon other tunnel syndromes were conceptualized, such as cubital tunnel syndrome, and tarsal tunnel syndrome.

In the human body, the carpal tunnel or carpal canal is a flattened body cavity on the flexor (palmar/volar) side of the wrist, bounded by the carpal bones and flexor retinaculum. It forms the passageway that transmits the median nerve and the tendons of the extrinsic flexor muscles of the hand from the forearm to the hand . [ 1 ]
Thread carpal tunnel release (TCTR) is a minimally-invasive procedure of performing carpal tunnel release using a piece of surgical dissecting thread as a dividing element. [1] This is instead of using a scalpel as in the situation of open carpal tunnel release (OCTR) or endoscopic carpal tunnel release (ECTR).
