Because spinal disorders
often occur in multiple levels of the spine and can range from the neck
(cervical spine) to the upper middle back (thoracic spine), there was
a great need for a flexible fixation system that would offer physicians
multiple options while treating these difficult cases. The VERTEX® Reconstruction
System utilizes various attachment mechanisms, which allow the physician
the freedom to choose what "instrumentation" will be best for the specific
patient they are operating on. Mechanically and conceptually this system
is somewhat like several other systems, which have been used successfully
for years: CD HORIZON® Multi-Axial Screws, Low Profile CROSSLINK® Plates
and the number one used cervical plate the ATLANTIS™ System.
By developing "modular
elements" Medtronic Sofamor Danek created a system that allows the surgeon
to tailor each construct to the individual patient's requirements. This
"customization" means a greater emphasis can be placed on the individual
patient's needs because the physician does not have to focus on making
the patient's anatomy fit the construct.
In order to provide
today's spine surgeon with the tools needed to address instability of
the cervico-thoracic junction, Medtronic Sofamor Danek introduces the
VERTEX® Reconstruction System. The junction between the cervical and
thoracic spines is a complex anatomic structure and stabilization of
this junction is difficult because it is the site of transition between
a flexible cervical spine and a rigid thoracic spine.
The unique complexities
of the cervico-thoracic junction, combined with the frequent occurrence
of spinal instability at this site (traumatic injuries to the cervico-thoracic
junction have been reported to occur in as many as 9% of all cervical
spine injuries), necessitate a specially designed fixation system in
order to optimize clinical outcomes.
The VERTEX® System
has been designed as a comprehensive modular implant system, utilizing
multiple fixation options while minimizing the profile of the hardware
in order to accommodate changes in flexibility and anatomy at this site.
To achieve these goals, the VERTEX® Reconstruction System utilizes multi-axial
screws for the thoracic region, lateral offset connectors, hooks, and
CROSSLINK® Connectors. The modular nature of this implant system allows
the surgeon to tailor each construct to individual patient requirements.
The VERTEX®
System utilizes a clinically proven cancellous bone screw design with
a reverse angle on the backside of the thread to enhance bone purchase
and pull-out resistance. This screw is well known to surgeons as part
of the fixation system of the ATLANTIS™ Anterior Cervical Plate System.
In the VERTEX® System, a multi-axial rod to screw connector permits
3 dimensional freedom of screw placement and trajectory which maximizes
bony purchase and minimizes the amount of rod contouring necessary to
reduce the spine to the rod.
It is important
that you discuss the potential risks, complications, and benefits of
VERTEX® Reconstruction System with your doctor prior to receiving treatment,
and that you rely on your physician's judgment. Only your doctor can
determine whether you are a suitable candidate for this treatment.
