Summary
The aim of this study is to compare two different pain management interventions in patients
undergoing reverse total shoulder arthroplasty. The two interventions are 1) pre-operative
interscalene nerve block and 2) intraoperative injection of liposomal bupivacaine (Exparel,
Pacira Pharmaceuticals, Parsippany NJ). Specifically, the primary aims of this study are to
compare these two interventions on the following: post-operative opioid consumption, pain
scores, and patient satisfaction. Additionally, the investigators want to determine if
psychological factors, catastrophizing and resilience, are associated with post-operative
pain control and satisfaction. The investigators' hypothesis is that the two interventions
will have similar pain control efficacy and that the liposomal bupivacaine group will
experience faster post-operative recovery, earlier discharge, and improved satisfaction. The
investigators also expect patient catastrophizing and resilience to significantly predict the
degree of post-operative pain and level of patient satisfaction.
