A Prospective Study to Compare Bupivacaine and Exparel Versus Bupivacaine or Exparel Alone for Postoperative Pain Relief

Combined Administration of Bupivacaine and Exparel Versus Bupivacaine or Exparel Alone for Postoperative Analgesia in Posterior Lumbar Spine Surgery - A Prospective Randomized Study


Lead Sponsor: Virtua Health, Inc.

Source Virtua Health, Inc.
Brief Summary

The purpose of this study is to collect information about how patients feel when doctors manage their pain after lumbar spine surgery using a combination of EXPAREL® and bupivacaine injected into the lumbar spine at the end of surgery, compared to the patients that doctors use only EXPAREL® or bupivacaine to manage their pain. This information will help doctors determine which approach works best for patients who will receive surgery in their lumbar spine in the future.
