Historically, carpal tunnel release was performed under general anesthesia with a tourniquet, however the worldwide trend is now for 'wide awake hand surgery': with no tourniquet, no general or regional anesthesia and no sedation; which also enables carpal tunnel release to be performed under local anesthesia as a one stop procedure. [14] After ...
Nerve decompressions are still a relatively new surgery, however a picture emerges from looking at the outcomes of some of the most studied nerve decompressions: carpal tunnel release, sciatic nerve decompression, and migraine surgery. Even within these commonly performed surgeries, the measurement of outcomes is not always standardized.
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).
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.
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 ]
At the 2007 meeting of the American Society for Surgery of the Hand, a former advocate of endoscopic carpal tunnel release, Thomas J. Fischer, MD, retracted his advocacy of the technique, based on his own personal assessment that the benefit of the procedure (slightly faster recovery) did not outweigh the risk of injury to the median nerve.
Protocols vary depending on local standard procedures and the extremity being operated on. A vast majority of practitioners begin by exsanguinating the limb as Bier did with an elastic bandage (Esmarch bandage), squeezing blood proximally toward the heart, then pneumatic tourniquets are applied to the limb and inflated 30mmHg above arterial pressure to occlude all blood vessels and then the ...
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.
