Study Summary

The purpose of this research is to determine if both local anesthetics (mepivacaine and bupivacaine) are similar in their onset of sensory block to assess the efficiency of ultrasound-guided ankle blocks in our practice. Currently it is the standard of care to perform ankles blocks with both mepivacaine and bupivacaine. However, given similarity in their safety profile researchers would like to compare if one is non-inferior to the other in terms of onset time of ankle block.
