Currently, increase in outpatient surgeries popularized regional anesthesia. Regional anesthesia is not only cost effective, but it also allows a fast ambulation. Regional anesthesia can be divided into three categories: central blocks including epidural and spinal blocks, peripheral nerve blocks and field blocks. The main advantage of peripheral nerve block over general anesthesia and other regional anesthesia techniques is that it is restricted to the area innervated by the nerve. The improvements in needle, perineural catheters and nerve stimulators, and the introduction of ultrasound to nerve blocks, increased the success rate in peripheral nerve blocks. This article mainly focuses on ankle blocks indicated for procedures of the foot that do not require a tourniquet.
