Sonographically guided percutaneous carpal tunnel release - An anatomic and cadaveric study

Minimally invasive techniques have become the standard of care for multiple procedures. This paper demonstrates both the surgeons' capacity to perform an accurate anatomic evaluation of the hand and forearm (n = 10) and the use of this anatomic information to accurately perform sonographically guided, percutaneous carpal tunnel release using a single-portal endoscope without direct or indirect visualization in a cadaver model (n 6). Open dissection was then performed to confirm complete ligament transection and to evaluate the surrounding structures for injury. In all 6 cadavers, the transverse carpal ligament was transected completely without injury to any surrounding structures. With further investigation, this novel technique may offer a less invasive, office-based method for the surgical treatment of carpal tunnel syndrome that may offer patients an expedited recovery.
