Patients scheduled to have foot and ankle surgery will typically receive a single shot sciatic nerve block to serve as the primary anesthetic and as part of a multi-modal post-operative analgesic plan. The investigators are investigating the use of perineural dexamethasone together with local anesthetics can improve the quality of recovery for patients receiving sciatic nerve blocks for foot and ankle surgery.
