The 5-in-2 Ankle Block for Outpatient Foot Surgery: the FIT Block Study

"The FIT block is a new approach for regional anesthetic block of the ankle. We use an optimized ultrasound guided approach for the FIT Block, based on optimal nerve anatomical locations. A one puncture proximal approach for the fibular nerves is used, while maintaining the benefit of preserved extrinsic motricity. Another one puncture approaches the sural nerve laterally, after the block of the tibial nerve during the same puncture and then the subcutaneous infiltration of the saphenous nerve. An anatomical proof of concept study has been done before the exploratory clinical study.~These approaches permit a surgical anesthetic block for foot surgery using 2 punctures (instead of 5) with a single patient's body position, compatible with sedation."
