Introduction
It is estimated that 80-85% of the population of the
U.S. will experience significant pain as a result
of spinal conditions within their lifetime. Diseased
conditions related to the neck, also called the cervical
spine, are often associated with neck and/or arm
pain.
Your cervical spine is made up of seven bones
(vertebrae), with an intervertebral disc between
each vertebra. The
disc has a thick outer layer (annulus) that surrounds
the soft gel-like center (nucleus). Each vertebra also
contacts neighboring vertebrae in the back (posterior)
portion of the spine at the articulating joints (facets).
The natural motion of the spine involves movement between
each vertebra, compression of the disc and sliding
contact of the facet joints. The disc acts as
a shock-absorber between vertebrae.
Neck
and/or arm pain is a common aliment of the cervical
spine, which may be due to impingement (compression)
of the spinal cord or nerve roots. With normal everyday
activities and over many years, the soft nucleus may
become thinner and more brittle, causing the spaces
between the vertebrae to become narrower. This
degenerative process may result in compression of the
spinal cord or nerve roots, causing pain. Slipped or
herniated discs (herniated nucleus pulposus) are conditions
in which all or part of the nucleus protrudes through
a weakened part of the annulus. This also causes pressure
on the spinal cord or nerve roots, resulting in neck
and/or arm pain. Such pain may also be caused by excessive
growth of bone (osteophyte formation) near the spinal
cord.
Spinal fusion remains the treatment of choice
for many degenerative conditions; however the results
of standard fusion techniques vary significantly. Motion-sparing
non-fusion devices such as artificial disc replacements
may provide alternatives for treatment of these conditions.
The SECURE®-C Cervical Artificial Disc was developed
as a potential alternative to spinal fusion. SECURE®-C
is an artificial disc replacement device inserted anteriorly
into the cervical spine, designed to help alleviate
pain and retain or improve function.
Study Objectives
The objective of this clinical trial is to evaluate
the safety and effectiveness of the SECURE®-C
Cervical Artificial Disc for the treatment of symptomatic
cervical disc disease as compared to anterior cervical
discectomy and fusion.
Study Overview
This FDA controlled, prospective, randomized study
will involve several hundred randomized subjects
at up to 20 sites in the U.S. Patients having
met all inclusion/exclusion criteria, having signed
the informed consent, and deciding to participate
in the study will be included in the trial. Participants
will be randomly assigned to either the investigational
group (SECURE®-C Cervical Artificial Disc) or
the control group (anterior cervical discectomy and
fusion).
Following surgery, patients return to their study
physician for scheduled visits to report on their outcomes,
including pain relief and function, etc. These
outcomes will be used to evaluate the safety and efficacy
of the procedure.
