A single blinded RCT for adult patients with spine pain. One group had a lumbar laminectomy with denervation of the facet joint at the level decompressed. The other group had a lumbar laminectomy without facet joint denervation. Both groups had their back pain and functional limitations measured using a 10 cm visual analogue scale and the Oswestry disability index (ODI). All measures were taken before surgery and at patients' 6, 12 and 24 week follow-up clinic visit.

Change in Visual analog scale for pain (VAS)
10 centimeter scale with a minimum of 0 indicating no pain and a maximum of 10 indicating worst pain.
Time frame: change from baseline score at 24 weeks
Change in Modified Oswestry Disability score (ODI)
The ODI is divided into ten sections designed to assess limitations of various activities of daily living. Each section is scored on a 0-5 scale. The range of scores is 0 to a maximum of 60. The total score is multiplied by 2 and expressed as a percentage. A score of 0 to 20 points indicates minimal disability; 20 to 40 points, moderate disability; and 40 to 60 points, severe disability.
Time frame: change from baseline score at 24 weeks
