Brief Summary
Surgery initiates a complex cascade of events involving the release of chemical compounds from nerve endings and damaged tissue which leads to an inflammatory and pain response. The purpose of this investigation is to measure various chemical mediators in the blood and cerebrospinal fluid, and to test the hypothesis that they will be decreased in patients treated with a COX-2 inhibitor.
