[The truncal blocks of the foot]

Abstract

Among the five branches of principal nerves trunks supplying the ankle and foot, only the tibial nerve is sometimes difficult to block at the ankle, at the border of the medial malleolus. Using new landmarks at the level of the sustentaculum tali overcomes this problem. Blocking these five nerves make possible all surgical procedures on the foot and provide excellent postoperative analgesia. Only tourniquet is a limit for these blocks.
