Injections were administered in a standardized fashion and included injection of a 1:1 mixture of a 40 mL solution consisting of 1.3% Exparel and sterile saline (interventional) or a 40 mL injection of normal saline (control) into the surrounding periosteal, peritendinous, surrounding muscles and subcutaneous tissue of the surgical incision(s).<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Main Outcome Measurements:<\/jats:title>\n            <jats:p>Pain medications administered and pain according to the Visual Analogue Scale was recorded at scheduled postoperative time points: 4, 24, 48, 72, and 336 hours (14 days).<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results:<\/jats:title>\n            <jats:p>Thirty-nine patients were randomized to the control group and 37 to the interventional group (mean age = 42 \u00b1 15 years), with no statistically significant differences between groups with regards to severity of injury and patient demographics. Pain scores were significantly lower in the interventional group versus control up to 2 weeks after surgery. Percocet ingestion at 4 hours was significantly lower in the interventional group (0.7 vs. 1.3, <jats:italic toggle=\"yes\">P<\/jats:italic> = 0.004), while it approached significance at 48 hours postoperatively (2.8 vs. 3.69, <jats:italic toggle=\"yes\">P<\/jats:italic> = 0.07). No other significant differences were noted for Percocet ingestion postoperatively at other time points assessed. The overall satisfaction with pain control was not statistically different between the 2 groups (<jats:italic toggle=\"yes\">P<\/jats:italic> = 0.93).<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusion:<\/jats:title>\n            <jats:p>Local intraoperative infiltration of liposomal bupivacaine administered with standard bupivacaine for ankle fractures requiring Open Reduction Internal Fixation (ORIF) affords improved pain relief in the immediate postoperative period resulting in a reduction in Percocet ingestion, with resultant effects seen up to 2 days postoperatively.
