The primary aim of this study is to assess the impact of intrathecal morphine on
post-operative pain following instrumented fusion for degenerative lumbar spine disease.
Secondary objectives of this study aim to assess side effects, overall narcotic use and
duration of hospital stay following administration of intrathecal morphine.
Based on our literature review, we expect a significant improvement in pain scores and
functional status and minimal side effects with the use of intrathecal morphine. With
improved pain and function we would also expect shorter hospital stays in those patients
receiving intrathecal morphine.
