Preliminary results of a randomized, equivalence trial of fluoroscopic caudal epidural injections in managing chronic low back pain: Part 4--Spinal stenosis.

摘要: BACKGROUND Spinal stenosis is one of the 3 most common diagnoses low back and leg symptoms which also include disc herniation degenerative spondylolisthesis. a narrowing spinal canal with encroachment on neural structures by surrounding bone soft tissue. In United States, commonly performed interventions for managing chronic pain are epidural injections, including their use stenosis. However, there have not been any randomized trials evidence limited regards to effectiveness injections in function-limiting lower extremity secondary lumbar STUDY DESIGN A randomized, double-blind, equivalence trial. SETTING An interventional management practice, specialty referral center, private practice setting States. OBJECTIVES To evaluate caudal or without steroids providing effective long-lasting relief differences between local anesthetic steroids. METHODS Patients were randomly assigned 2 groups, Group I patients receiving (lidocaine 0.5%), whereas II received 0.5% lidocaine 9 mL mixed 1 steroid. Randomization being computer-generated random allocation sequence simple randomization. OUTCOMES ASSESSMENT Multiple outcome measures utilized included Numeric Rating Scale (NRS), Oswestry Disability Index 2.0 (ODI), employment status, opioid intake assessment at months, 6 12 months post-treatment. Significant was defined as 50% more, significant improvement disability score reduction 40% more. RESULTS (> =50%) demonstrated 55% 65% functional status ODI scores 80% patients. The overall average procedures per year 3.4 +/- 1.27 2.6 1.35 an total 30.3 19.49 weeks 23.1 21.36 over period 52 weeks. LIMITATIONS results this study lack placebo group preliminary report 20 each group, even though sample justified. CONCLUSION Caudal may be approximately 60%
