Brief Summary:
The primary objective of this pilot study is to assess the feasibility of comparing two standardized approaches to manage post-operative pain following spine surgery: one approach using Patient Controlled Analgesia (PCA) devices to deliver opioid analgesics, and the other approach using EXPAREL® infiltration at the site of surgery and nurse-administered opioid analgesics.

Condition or disease Intervention/treatment
Pain Management Analgesia Anesthetic Drug: Opioids delivered through PCA Drug: EXPAREL® infiltration

Detailed Description:
The study will assess the feasibility of the methods proposed, including recruitment, eligibility, standardization of both post-operative pain management approaches, and assessment of clinical, hospital efficiency, medication use, health services use, and economic outcomes.
