Regional Anaesthesia of the Foot Achieved from Two Cutaneous Points of Injection: An Anatomical Study
2009
Abstract
Regional anaesthesia for the lower extremity distal to the ankle joint, knows as anaesthetic ankle block or foot block, involves a series of injections of local anaesthetic to block the peripheral nerves that supply innervation to the foot. Since the tibial nerve block is not always effective, the aim of this study was to design a modified technique of anaesthetic application.
The results of this anatomical study provided a basis for a modified technique of regional anaesthesia of the foot. Its major clinical attributes involve reduced necessity to manipulate with the patient, and sensory and motor blockage of all nerves supplying innervation to the foot from only two points of injection.
