A review of regional blocks for the foot

The blocking of the posterior tibial, sural, saphenous, superficial peroneal, and the deep peroneal nerves with possible alternative approaches is discussed. Digital blocks, Mayo blocks, and intravenous regional anesthesia are also discussed. The placement of the tourniquet above the ankle but below the calf muscles will avoid deep muscle pain. Lidocaine and bupivacaine cause vasodilatation in the foot.
