The use of ultrasound for peripheral nerve blocks has proven extremely useful for improving the accuracy and efficacy of many regional anesthetic techniques. There remain a few nerve blocks which have lagged behind in employing the assistance of ultrasound consistently, one of which is the ankle block. This block is commonly utilized for either surgical anesthesia or post-operative analgesia for a variety of foot and ankle procedures. The objective of this study was to compare the accuracy of traditional anatomical landmark-guided technique with an ultrasound-guided approach for ankle block by assessing the spread of injectate along the posterior tibial nerve (PTN) in cadaver models.
