Surgeons with the Indiana Spine Group performed the first
artificial cervical implant surgery in the United States. SpineUniverse talked with
Rick Sasso, M.D., one of the spine surgeons who performed the surgery. Dr. Sasso
is also a SpineUniverse Editorial Board member.
SpineUniverse: Dr. Sasso, congratulations on this remarkable surgery!
Can you tell us a little bit about the procedure?
Dr. Sasso: Thank you. We performed the surgery at St. Vincent Hospital
in Indianapolis. The procedure utilized an artificial cervical disc, which resembles
a normal human disc but is made out of titanium with a polyurethane nucleus.
The artificial disc was inserted into the damaged disc space of the patient
in order to restore disc height, improve mobility and flexibility, and eliminate
his debilitating pain.

SpineUniverse: What type of cervical condition did the patient have?
Dr. Sasso: Our patient was a 41-year-old male who suffered from a herniated
cervical disc as a result of an injury he sustained in an automobile crash 6
months prior. His injury severely limited his neck movement and caused severe
left arm pain. He was an ideal candidate for the implant surgery; especially
since the numerous pain management strategies he tried were ineffective.

SpineUniverse: How has this type of surgery traditionally been performed?
Dr. Sasso: The current standard surgical procedure, called anterior
cervical fusion, involves the use of instrumentation such as a metal plate or
pins to help stabilize the neck. The surgery also involves fusion - when a piece
of bone taken from either the patient's hip or a human cadaver is implanted
into the disc space in order to fuse the vertebrae together. The purpose of
the surgery is to limit movement in the spine and thereby reduce or eliminate
pain.

SpineUniverse: How is using an artificial disc better than relying on fusion?
Dr. Sasso: The use of the new artificial disc eliminates the need for
both instrumentation and bone grafts. This is preferable because there are disadvantages
to bone grafting including the need for an additional incision, pain and soreness
at the graft site (which often last well after the surgery), as well as the
potential surgical complications that accompany grafting. Even when we use a
patient's own bone, 100% fusion rates are not always achieved. In addition,
fusion surgery results in a significant loss of neck mobility. The artificial
disc provides patients with more normal neck movement than the traditional fusion
surgery.
SpineUniverse: Are artificial cervical discs available everywhere?
Dr. Sasso: Not yet. We are very proud to be one of only 20 centers in
the United States with access to this technology. However, as more of these
surgeries are performed, and the outcomes are measured, we are hopeful that
this technology will become the new standard surgical procedure for disc problems
- not just in the cervical spine but in other areas of the spine as well.
SpineUniverse: Thank you Dr. Sasso. We look forward to hearing more
about these surgeries in the future.
Dr. Sasso: My pleasure. I will be sure to keep you informed on our research
in this area.
