BACKGROUND: Radiofrequency heating of the intervertebral disc has been proposed for the treatment of chronic low back pain using two methods: a flexible needle inserted into the annulus fibrosus achieving a full 360 degrees penetration, or a rigid needle inserted into the nucleus pulposus. The first technique is effective on pain, but the clinical benefit of the second is uncertain. PURPOSE: To evaluate a technique for radiofrequency heating of the lumbar intervertebral disc by a needle placed into the nucleus pulposus. MATERIAL AND METHODS: The method was tested in 17 patients according to the criteria used in previous intradiscal radiofrequency studies. Before and after treatment, disability was assessed by the Oswestry disability score. A pain reduction of at least 50% was considered a success. RESULTS: Fifteen patients were responders at 1 month (88%), nine at 3 months (53%), and 12 at 6 months (70.6%). No complications were observed. CONCLUSION: A new method of providing discal radiofrequency treatment for lower back pain had a substantial clinical benefit in 71% of the observed patients. A prospective study comparing this new method with placebo should be conducted to confirm these initial results. |
