Brief Summary
All patients scheduled for lumbar spine surgery due to discogenic low back pain and/or sciatica, will be screened by the principal investigator for presence of inclusion/exclusion criteria. Their baseline neurological function before surgery will be assessed and recorded for recruitment into one of the three study groups. MRI scans will be assessed for the calculation of disc protrusion size. Experimental sensory and pain assessments and questionnaires will be performed at list 24 hours before surgery. Blood sample for pro-inflammatory mediator will be obtained at the same time as the experimental sensory and pain tests. Pre-operative pain and MPQ will be assessed pre-operatively (back and leg pain separately), and again on day 30 after surgery. Blood tests for ESR, CRP will be drawn before surgery, during the surgery, and on 30 after surgery. During surgery, intervertebral disc material will be harvested and divided into 4 specimens for culture and inflammatory mediator analysis. Repeat neurological assessment will be performed 30 after surgery.
