Procedural Technique for Wide Awake Local Anesthesia No Tourniquet Injection for Endoscopic Carpal Tunnel Release.

Carpal tunnel syndrome is the most common upper extremity peripheral neuropathy syndrome. Treatment ranges from nonsurgical methods, including night-orthosis fabrication and corticosteroid injections to surgical management via a carpal tunnel release (CTR). Carpal tunnel release alleviates nerve compression by releasing the transverse carpal ligament, and performed as either an open CTR (OCTR) or endoscopic CTR (ECTR) procedure. However, there is no consensus on the superiority of the 2 approaches. Practitioners may be limited to 1 technique because of surgeons' comfort, access to an operating room versus a procedure room, and cost. The purpose of this article was to describe the surgical technique for wide awake, local anesthesia, no tourniquet ECTR performed in an office-based setting, which would decrease operating room demand and cost.
