The primary outcome measure is pain score at 24 hours, which will be obtained by phone follow up. Secondary outcomes include maximal pain score on postoperative day 1, 2 and 3, total oral opioid morphine equivalent after 3 days, and occurrence of typical opioid side effects (nausea, vomiting, drowsiness). In addition to follow up phone call on postoperative day 1, patients will keep a pain diary, documenting pain scores and opioid use for the first 72 hours, which will be collected by the surgeon in his office at the first postoperative visit. Any adverse occurrences related to nerve blockade or prolonged bupivacaine effect will also be recorded.
