Ultrasound-guided Mid-humeral Radial Nerve Block Provides Sufficient Surgical Anesthesia at Hand Dorsum: A Novel Method and Report of Three Cases

A peripheral nerve block is a sufficient anesthesia method for hand surgeries, as it protects the patient from the complications of general anesthesia and provides postoperative analgesia. We report the first use of an ultrasound-guided mid-humeral radial nerve block in three cases of ganglion cyst excision from hand dorsum. The block provided efficient surgical anesthesia and postoperative analgesia for the excision of ganglion cysts at the hand dorsum.
