76 Dailey, Andrew T.Guideline update for the performance of fusion procedures for degenerative disease of the lumbar spine. Part 13: Injection therapies, low-back pain, and lumbar fusionThe medical literature continues to fail to support the use of lumbar epidural injections for long-term relief of chronic back pain without radiculopathy. There is limited support for the use of lumbar epidural injections for short-term relief in selected patients with chronic back pain. Lumbar intr...2014-01-01
77 Dailey, Andrew T.Guideline update for the performance of fusion procedures for degenerative disease of the lumbar spine. Part 14: Brace therapy as an adjunct to or substitute for lumbar fusionThe utilization of orthotic devices for lumbar degenerative disease has been justified from both a prognostic and therapeutic perspective.
