Nucleoplasty FAQs
What is
Nucleoplasty®?
Nucleoplasty is a procedure name used to describe a disc
decompression procedure performed using Coblation® technology to
remove tissue in the nucleus pulposus of the disc. Nucleoplasty
utilizes a minimally invasive approach to remove disc material and
decompress the disc. This is accomplished via a multifunctional
bipolar radio frequency device that utilizes Coblation technology to
ablate, or remove tissue. Because tissue removal is achieved at
temperatures of approximately 40-70ºC, thermal damage to surrounding
tissue is minimized. Coblation technology has been used in over 4.5
million procedures to date.
Are the products and technology used in this
procedure FDA approved?
Yes. The SpineWandsTM, including the Perc DLR, Perc DLG, and Perc DC
have specific FDA 510(k) clearance for "ablation, coagulation, and
decompression of disc material to treat symptomatic patients with
contained herniated discs." The products are also CE Marked.
What are the key elements of the procedure?
Nucleoplasty is performed on an outpatient basis, with minimal
anesthesia requirements. Fluoroscopic guidance is employed as an
introducer needle is placed at the nucleus/annulus junction. A
SpineWand is introduced through the passage way, and advanced into
the disc nucleus. Using Coblation, tissue is then removed by either
creating channels (lumbar spine) or spheres (cervical spine). After
sufficient tissue is removed, both the device and introducer needle
are removed, a bandage is placed on the skin and the patient is
discharged home. Patients are then usually placed on a routine
rehabilitation program as part of a standard protocol for
interventional spine procedures.
Do you need to aspirate the by-products
from ablation?
No. The low molecular weight gases produced by ablation pass out of
the disc via the introducer needle. Cadaver and animal studies,
along with anecdotal experience, and Percutaneous Lumbar Disc
Decompression (PLDD) clinical experience, confirm that aspiration is
unnecessary.
Can you do the procedure immediately after
a discogram?
Yes. The 17 gauge Crawford needle can be used for access (when
performing the discogram), and the needle can remain in place in the
annulus for the Nucleoplasty procedure. For improved imaging of the
DLR Wand, physicians have suggested a 50% dilution of the contrast
used during the discogram.
In the past both Ablation and Coagulation
mode were utilized, why does ArthroCare now recommend usage of
Ablation mode only?
ArthroCare made this recommendation a number of years ago.
Nucleoplasty has two effects, the removal of tissue (i.e.
decompression) and also positive biochemical changes. Both of these
effects occur during the Ablation mode. Based on this information,
ArthroCare’s scientific advisory board no longer recommends the use
of coagulation mode for the Nucleoplasty procedure as it not
necessary for clinical effect. Not adding any additional heat (as
used in the coagulation mode) may also increase the safety of the
procedure and potentially reduce the risk of complication.
Can more than six channels be created?
Some practitioners have used more than six channels, or used a
bilateral approach creating up to twelve channels in total.
Therefore, the clinician should determine the amount of tissue to be
removed based upon the patient's symptoms and anatomy.
Should a physician inject antibiotics after
Nucleoplasty?
Use of antibiotics is not required. However, many physicians
will administer antibiotics anytime the annulus is penetrated – due
to the increased risk of infection leading to discitis (inflammation
of the disc). They generally use the same dose as following a
discogram.
Does a Nucleoplasty patient need to wear a
brace after the procedure?
A brace is not required, since the annulus has not been compromised
by the procedure. However, a number of Nucleoplasty centers are
using a soft brace for two reasons:
- The brace reminds the patient that they have had a minimally
invasive procedure, and they should allow their back to heal (as
they progressively return to normal activities).
- The brace requires the patient to maintain good posture for their
lower spine – as part of an overall program of post-procedure
rehabilitation (to teach the patient good habits for spine posture
and conditioning). A Rehabilitation protocol is intended to support
an optimal outcome from the Nucleoplasty procedure, while helping
the patient to avoid re-injury.
Is a Rehabilitation Protocol recommended
following the procedure?
A rehabilitation protocol is recommended, but not necessarily
required. Most centers have utilized the same rehabilitation
guidelines as they utilize for other interventional spine
procedures: bed rest for several days, progressive use of stretching
and strengthening exercises, followed by staged return to more
normal activities.
What research is currently underway?
Extensive studies have been completed to document the affects of the
procedure. Basic science research includes studies of the
biochemistry, histology (acute and chronic), temperature, and
pressure relative to the Coblation assisted decompression.
Clinically, multiple centers around the world, both in University
and private practice settings are conducting clinical trials. There
are independent studies taking place in the United States, Europe,
South America, and the Far East. A number of these studies, both
basic science and clinical, have been accepted for presentation at
various clinical meetings. A number of multi-center randomized
controlled trials are currently underway comparing Nucleoplasty to a
variety of other treatment options.
