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.
