The block has been well described in the anesthesia community since it was first introduced by Hebbard and Royse in 2007 . In 2017, Luftig first described the block's use in the ED setting for a variety of indications . This nerve block has classically been described to provide extensive anesthesia for procedures distal to the shoulder, such as elbow dislocations, distal radius fractures, and surgical procedures.",[70],"Pain Management","2026-05-02",{"date":73,"type":74},"2026-05-07","ACTUAL",{"date":76,"type":74},"2026-04-01",{"date":78,"type":64},"2026-12-01",{"name":5,"class":6},1]
