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.

Patients will receive a local injection of liposomal bupivacaine near the end of their shoulder arthroplasty operation.
Patients will undergo a pre-operative interscalene nerve block performed by the anesthesiology team.
University of Cincinnati Medical Center
Cincinnati, Ohio, United States
Opioid Consumption
Post-operative use of opioid pain medications, measured in morphine equivalents (higher scores are worse)
Time frame: 72 hours post-operatively
Visual Analog Scale Pain Scores
Post-operative level of pain measured from 0 (no pain) to 10 (worst pain)
Time frame: 72 hours post-operatively
Patient Satisfaction: Rating
Rating of satisfaction with post-operative pain management from 0 (least satisfied) to 10 (most satisfied)
Time frame: 72 hours post-operatively
Relationship between catastrophizing, pain, and patient satisfaction
The effect of patient catastrophizing (measured using the Pain Catastrophizing Scale) on post-operative pain control and satisfaction. The Pain Catastrophizing Scale measures how individuals psychologically respond to pain and hardship, and it ranges from a minimum score of 0 to a maximum score of 52. Higher scores on the Pain Catastrophizing Scale indicate more catastrophic thinking. The patients' catastrophizing scores will be correlated with their post-operative pain scores and their satisfaction scores. A correlation closer to -1 or 1 (correlations range from -1 to 1) indicates a stronger relationship between catastrophizing with pain control and satisfaction.
Time frame: Catastrophizing will be measured pre-operatively
Relationship between resilience, pain, and patient satisfaction
The effect of patient resilience (measured using the Brief Resilience Scale) on post-operative pain control and satisfaction. The Brief Resilience Scale measures how individuals psychologically respond to pain and hardship, and it ranges from a minimum score of 1 to a maximum score of 5. Higher scores on the Brief Resilience Scale indicate greater resilience. The patients' resilience scores will be correlated with their post-operative pain scores and their satisfaction scores. A correlation closer to -1 or 1 (correlations range from -1 to 1) indicates a stronger relationship between resilience with pain control and satisfaction.
Time frame: Resilience will be measured pre-operatively
