AbstractThe Mayo block is an extremely efficacious regional anesthetic technique used to provide anesthesia of the forefoot. Patients requiring surgical correction of hallux deformity, bunionectomy, and first metatarsal surgery may benefit from this technique. The Mayo block is a field block that anesthetizes the specific nerves of the forefoot that innervate the surgical field. This technique requires less local anesthesia than that required by direct local anesthetic infiltration and does not distort the surgical tissue planes. The Mayo block is effective. This technique has been used at one military hospital on more than 275 patients. The failure rate of the block is less than 1%. Learning this technique adds to the anesthetist's armamentarium of regional anesthesia, aids in rapid case turnover, and avoids the risks associated with major conduction and general anesthesia.
