Herniated Cervical Disc Replacement
By Peter
Johnson
There are various factors which need to be considered before
herniated
cervical disc replacement is decided on
as a herniated disc treatment option as opposed to fusion
surgery or conventional decompression. The pro’s and con’s
of cervical disc replacement can only be understood with
in-depth, long term and numerous studies, this mean previous
research and cases need to be analyzed before being pursued.
Currently, a large portion of the data on cervical disc
replacement is based on theories.
In general, the
circumstances that indicate that there may be a need for
cervical disc replacement are similar to the indications for
fusion surgery or discectomy. The cervical disc of the
patient must be symptomatic, which may be resulting to pain,
numbness or weakness in the arm with some amount of neck
pain. Such symptoms may be caused by osteophytes that are
causing compression on the spinal or the surrounding nerves
and/ or a herniated disc. The methods of treatment are quite
different from other forms such as a herniated
lumbar disc.
In most examples the
patient in question must meet certain requirements before
cervical disc replacement will be considered as a viable
option. For example, the patient must have not
undergone prior surgery on the neck and he or she must go
through four up to six weeks of non-operative trial
treatments, typically including different forms of physical
therapy and medications. Overall, the patient must be
considered as a good candidate for
surgery.
Below is the
Cervical disc replacement
procedure
The standard procedure
in a cervical disc replacement surgery involves an anterior
approach, which is the same approach used for a fusion
surgery or discectomy. The surgeon will completely remove
the disc that is affected including any bone spurs or
impinging fragments of the disc. Then, then surgeon raises
the disc space to its normal height to aid in the
decompression on the nerves. This step is critical because
worn out discs usually shrink, and may result to pinched
nerves in one’s neck. Lastly, the surgeon implants the
artificial disc into the disc space with the use of x-ray or
fluoroscopy.
Like all other
surgeries, cervical disc replacement has its potential risks
including blood loss, infection, and paralysis or nerve
injury. While these risks are very serious, they occur very
rarely. Additionally, the artificial disc will naturally
wear out over time and small particles of it may cause some
reaction with the body. However, laboratory studies have
found that there over a period of ten years, there is only
minimal wearing out of the disc and that the body tolerates
the material well.
Cervical disc
replacement has benefits over a fusion surgery, one of which
is the elimination of the risks involved with using a bone
graft from the patient’s hip or the risk of infection when
the procedure uses “cadaveric” bone graft. Obviously, the
patient does not have to go through the healing process of a
bone graft with a cervical disc replacement. This procedure
allows a more normal motion for the neck and the patient is
able to perform more types of activities for longer after
the surgery.
Cervical disc
replacement should only be considered as a viable treatment
option for a herniated cervical disc when all other methods
of treatment have been exhausted. Patients will need to meet
several requirements, and this will all need to be
considered by the recommending physician or doctor who is
treating your herniated disc.
