stabilization is a revolutionary concept in spinal surgery.
For many years surgeons had limited tools to treat low back
pain. Patients were treated with conservative measures
such as physical therapy, and epidural steroid injections.
Failing these, the surgeon had the option of a decompression
surgery or a fusion. There is a large population of
patients for whom decompressions is not enough, but are not a
candidate for the more complicated and potentially risky fusion.
For these people, there is a new treatment paradigm:
dynamic stabilization. Dynamic stabilization includes many
different classes of products. For example, artificial
discs, represent a promising new market segment. Posterior
dynamic stabilization is highlighted by Zimmer’s Dynesys
product. Dynesys consists of pedicle screws with a rope
and a spacer instead of a rigid rod. It provides support
and takes a load off a degenerative disc or vertebral segment.
percutaneous (much smaller incisions are necessary) product
offers several advantages over the current Dynesys product:
to adjust the amount of support needed from one level to
risk of infections
stabilization is best known in the market place by the
artificial disc. The only disc cleared to market by the
FDA is Depuy’s Charite. Many more will follow. Scient’x has
a flexible rod construct (IsoLock). Several artificial facet
joints are in development phase. Medtronic is developing
transverse process stabilization. Spine Next sells Wallace. St.
Francis Medical Technologies, Inc. has X STOP. Surgicraft has
the Soft Stabilization System (SSS). Currently, Zimmer
Spine has FDA clearance to market for Dynesys only as an aid to
fusion. An IDE for dynamic stabilization completed enrollment in
January 2005. FDA clearance to market is expected in the fourth
quarter of 2007.
