A meta-analysis of
the Intradiscal ELECTROTHERMAL(TM) Therapy (IDET(TM)) procedure examining
outcomes of 17 clinical studies demonstrates that patients suffering from
chronic disc-related low back pain experience a significant decrease in
pain and improvement in physical function, as well as a low incidence of
complications. The study is published in the July/August issue of Pain
Medicine, the peer-reviewed journal of the American Academy of Pain
Medicine.
Study authors Dr. Gunnar B.J. Andersson, professor and chairman of
orthopedic surgery, Rush-Presbyterian-St. Luke's Medical Center, Chicago,
and Dr. Michael Totta, physiatrist of the Spine Center at Orthopedic
Associates of Portland in Portland, Maine, systematically synthesized all
peer-reviewed published literature describing outcomes following the IDET
procedure involving more than 500 patients. The majority of clinical
studies reported outcomes assessed from six to 24-months post-treatment.
"The collective study results provide compelling evidence that the IDET
procedure can significantly improve the quality of life for patients who
suffer from chronic disc-related low back pain and are seeking relief,"
said Dr. Andersson.
Meta-Analysis Results of IDET Procedure
Meta-analytic techniques applied to measurement tools, such as the
Visual Analog Scale (VAS) and Bodily Pain (BP) and Physical Functioning
(PF) subscales of the SF-36 and the Oswestry Disability Index (ODI), were
used to examine the overall treatment effects of the IDET procedure. The
most frequently reported efficacy outcomes were the improvements in the VAS
assessment of pain, and the BP and the PF subscales of the SF-36 health
survey and ODI. The safety of the IDET procedure was evaluated by pooling
the incidence of complications among the published literature.
Based on the meta-analysis, the review concludes that a statistically
significant decrease in pain is reported post-treatment. These authors
found a mean improvement of 2.9 points on the VAS and a mean improvement of
21 points on the BP subscale of the SF 36. Statistically significant
improvements in physical function were also recorded. These improvements
following the IDET procedure were accompanied by a low incidence of
complications.
"By gathering the results from all the studies on the IDET procedure,
we have reinforced that the entire body of evidence supports the
effectiveness of the procedure," said Dr. Totta. "A meta-analysis is a
statistical method that combines the results of several independent
clinical trials. By integrating the body of evidence for a procedure, a
meta-analysis allows for a more objective appraisal of the data and can
also contribute to considerations about the consistency of the study
results."
About the IDET Procedure
Intradiscal ELECTROTHERMAL(TM) Therapy (IDET) is a minimally invasive
outpatient surgical procedure for patients suffering from chronic
disc-related lower back pain who have failed a program of aggressive
non-operative therapy. During the procedure, controlled levels of thermal
heat are applied directly to the affected disc. The heat contracts and
thickens the collagen fibers within the disc wall, cauterizing the tiny
nerve endings that cause the pain and potentially closing the cracks and
tears.
The IDET procedure can be performed in less than one hour, is safe and
has a low incidence of complications. Since 1998, over 60 peer-reviewed
articles have been published on the IDET procedure supporting the
procedure's efficacy and safety.
