ABSTRACT
BACKGROUND:
Radiofrequency heating of the intervertebral disc has been proposed for the treatment of chronic low back pain using twomethods:
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 ANDMETHODS:
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.
