Pioneer(R) Surgical Technology Announces First Human Implants Of Its NuNec(TM) Cervical Arthroplasty Device

Pioneer Surgical Technology,
Inc., a leader in innovative medical devices, announced the
successful human implantation of its next generation cervical total disc
replacement (TDR), NuNec Cervical Arthroplasty Device. The surgeries were
performed by Drs. Hansen Yuan, Dewei Zou and Wenwen Wu in Beijing China, on
patients with degenerative disc disease (DDD) otherwise indicated for
standard fusion surgery.


Dr. Yuan, a designing surgeon team member for NuNec said, "This (NuNec)
is truly a one-of-a-kind, next generation cervical TDR. It features a
unique cam locking mechanism which provides optimum fixation without keel
cutting as well as an HA coating on the outer surfaces of the PEEK plates
to facilitate consistent biological fixation." Yuan added, "Unlike many
cervical disc devices, the radiolucency of the PEEK material in NuNec
causes no artifact in MRI or CT imaging."



According to Dr. Zou, an orthopedic surgeon and the President of 306
Hospital, "Our patients are fortunate to be able to benefit from this
innovative motion preservation technology. I have used several other
cervical TDRs in the past and NuNec is, by far, the easiest to implant.
These first patients have expressed immediate pain relief after receiving
the NuNec device and I am very pleased with these early results."



Pioneer's signature articulating P3(TM) Technology -- Pioneer
PEEK-on-PEEK -- is the heart of the NuNec design. Pioneer will showcase its
P3(TM) technology products -- NuBac(TM) Intradiscal Arthroplasty System,
NuNec(TM) Cervical Arthroplasty System, and BacJac(TM) Interspinous
Decompression System -- at the May 2008 Spine Arthroplasty Society (SAS)
meeting in Miami, FL.



Pioneer's CEO and President, Dr. Matthew N. Songer says, "We continue
to pioneer the P3 application in our motion preservation products. The
established biocompatibility, biodurability, radiolucency, and excellent
wear resistance of this technology provide surgeons with the most
technologically advanced design in the industry which we believe will lead
to reduced operating room times and better patient outcomes."



Earlier this year, Pioneer announced significant findings on the effect
of accelerated aging on the wear of PEEK (Poly-ether-ether-ketone). The
study, conducted in collaboration with RUSH University in Chicago,
determined that wear properties of PEEK-on-PEEK are not susceptible to the
effects of accelerated aging. The study bolsters support for the long term
durability of the company's P3 designs.
