Overview
Brief Summary
Postsurgical pain may effectively be treated with a multimodal approach that incorporates the use of local anesthetics. Bupivacaine is a local anesthetic that has been proven to be effective at reducing postsurgical pain. Furthermore, this local anesthetic has been shown to reduce opioid use, improve functional outcomes, allow for early mobilization, and decrease hospital length of stay. However, local anesthetics, via wound infiltration, are often short-acting and do not meet the duration of postsurgical pain due to their solubility and protein-binding properties. ExparelTM is an FDA-approved liposomal formulation of bupivacaine that allows for 72 hours of postsurgical analgesia with a single injection. This formulation has been shown to have little to no adverse effects; although some studies have reported adverse effects with the use of ExaprelTM, most frequently being nausea, vomiting, and dizziness. The occurrences of these adverse events were still less than the placebo cohort.
Detailed Description
All patients undergoing surgical fixation of a lower extremity fracture(s) will be offered the opportunity to enroll in the study. Patients undergoing unilateral or bilateral surgical fixation would be included. Written, informed consent to enrollment will be recorded and included in the patient record. The study is designed around the standard of care for postsurgical pain management. There are no additional costs to the patient strictly related to this study. Patients will undergo surgical fixation of a lower extremity fracture(s) by one of surgical investigators at a single institution. A sealed, opaque envelope, selected in the pre-operative holding area, will accompany each patient participant to the operating room. The envelope will be opened at the conclusion of the fracture fixation to reveal patient assignment to either study Group 1 or Group 2. Once the total numbers of patients have completed their procedures and follow-up, the study will close.

Arms & Interventions
Control- Marcain
Group 1 will receive non-liposomal bupivacaine introduced into the soft tissue surrounding the fracture at the conclusion of the surgery.
Intervention: Bupivacaine/Exparel
Experimental- Exparel
Group 2 will receive a mixture of non-liposomal bupivacaine and Exparel introduced into the soft tissue surrounding the fracture at the conclusion of the surgery.
Intervention: Bupivacaine/Exparel
Outcomes
Primary Outcomes
Change in Pain Visual Analogue Scale (VAS)
Time Frame: 72 hours
Patients will be asked to complete a Pain Visual Analogue Scale every 2 hours for the first 12 hours of their stay (2, 4, 6, 8, 10, 12), and then again at 24, 30 and 72 hours into their hospitalization.
Secondary Outcomes
- Pain Management Satisfaction(2 weeks, post-operatively)
