CENTER VALLEY, Pa.,
Sept. 25, 2018 /PRNewswire/ --
Aesculap Implant Systems, LLC today announced that critical
long-term data will be presented by Dr. Scott Blumenthal of the Center for Disc
Replacement at the Texas Back Institute during the NASS 2018 Annual
Meeting (Los Angeles, CA,
September 25-29, 2018). The post-hoc
analysis from the activL® Artificial Disc
Investigational Device Exemption study challenges common
misconceptions about the value of motion preservation at the
lumbosacral junction. Two different oral podium presentations will
be delivered during the NASS Annual Meeting examining the effects
of range of motion on long-term clinical outcomes. This data comes
one year after NASS panelists concluded that the body of evidence
for lumbar total disc replacement (TDR) supports lumbar TDR as a
standard of care for the treatment of discogenic chronic low back
pain.
"When we began analyzing the data specific to the performance of
these disc replacements at L5/S1, it became obvious that there are
reasons to avoid a fusion, if possible, at this level," said
Scott Blumenthal, MD. "Patients who
had six degrees of motion at L5/S1 five years postoperative
experienced 100% success in their VAS pain score improvement and
for every two degrees of motion were more likely to have Oswestry
success. That says a lot about the correlation between motion, pain
and function and why we do what we do."
The long-term data will also report on the long-term range of
motion outcomes between first and current generation lumbar disc
replacement designs and its impact on clinical outcomes and
adjacent segment disease. On average, activL® Artificial
Disc patients maintain their preoperative range of motion (6.6° vs.
6.1°, p=0.4) while ProDisc-L patients do not (6.2° vs. 4.2°,
p=0.02). This drop off in range of motion has been correlated to
increased progression of adjacent segment disease (8.8% vs. 19%,
p=0.05).
