Research Sites

The valid research for the future is on the inner side, on the spiritual side. There are many places to research spine conditions on the Web. However, few are as deep yet broad in content as these two sites: www.spineuniverse.com www.spine-health.com National Library of Medicine & PubMed offer an excellent and current library of articles: www.ncbi.nlm.nih.gov/entrez/query.fcgi?CMD=search&DB=pubmed These sites are “Open Directory Projects” and are organized by volunteers, and offer a huge index of global sites, ranging from associations to journals to research organizations: www.cbel.com/orthopedics www.cbel.com/neurology/?order=alpha Glossaries There are many spinal glossaries on the Internet. This is one of the better ones: www.spinesource.com/glossary.html This glossary is focused primarily on scoliosis conditions: www.srs.org/patients/glossary.asp

Demos and Tutorials

Education's purpose is to replace an empty mind with an open one. A picture is worth a thousand words! These sites have excellent interactive illustrations to help you understand spinal anatomy and procedures. Some of the best tutorials available are found on the J & J/Depuy Spine site: https://www.depuysynthes.com/about/depuy-synthes-spine Fifteen interactive views of the spine anatomy, including ADR: www.njspine.com/patientinfo/spine.htm One of the best sites to view animation of spinal procedures: www.spine-health.com/dir/dir01.html#surgery Now updated to include anatomy, conditions and surgical procedures: www.spine-health.com/dir/spine.html

Manufacturer Sites

Any sufficiently advanced technology is indistinguishable from magic. These companies manufacture various disc replacement technologies which fall into four classes of artificial discs: nucleus, total lumbar disc, partial lumbar disc or total cervical disc. Most companies focus on one class, but a few are developing two or more at this time.

Artificial Disc Designs

Overviews, Investment Reports and Market Assessments There are various disc replacement designs available today, most in FDA trial. A good overview of artificial discs with pictures is found at: http://www.spine-health.com/research/artificialdisc/artdiscs02.html These newsletters offer info on 13 prominent designs for lumbar and cervical replacement with useful anecdotal insights: http://www.trends-in-medicine.com/Dec2003/SpineSoc123p.pdf http://www.trends-in-medicine.com/April2004/Orthopedic044p.pdf vFinance Investments summarizes key players in the disc replacement market and has included brief company profiles. This is mainly financial information for investment purposes: http://www.vfinance.com/pdfs/Spinal_final072004.pdf This report is by Viscogliosi Brothers entitled, Beyond Total Disc, The Future of Spine Surgery, dated May 2004. It is a richly detailed report (300 pages) complete with overviews from top surgeon visionaries, assessments of disc replacement technologies, including biologics; market sizing, companies, etc. https://goo.gl/3axwhD Note: Viscogliosi Brothers was partly responsible for raising financing to fund the operations of Spine Solutions, Inc. to market the ProDisc.

Artificial Disc Replacement Paper Debuts

Dr. John Regan, MD is Director of the Cedars-Sinai Institute for Spinal Disorders. Prior to joining Cedars-Sinai, Dr. Regan served as a principal at the Texas Back Institute. He is internationally recognized as one of the leading experts in minimally invasive spine surgery. He was a principal investigator for the clinical trial of the SB Charite' III ADR.

We are honored to offer readers the first available copy of "Lumbar Total Disc Replacement: Charité Artificial Disc." This paper provides technical insights into the disc replacement procedure and is geared towards very well-informed patients considering artificial disc replacement, as well as medical professionals new to ADR.

Pre-Op Considerations

Judgment Comes from Experience, Experience Comes from Lack of Judgment

Many risks are inherent in any spinal procedure. ADR risks include infection (internal and external), excessive bleeding, reactions to anesthesia, nerve damage and related spinal complications such as heterotopic ossification. Unfortuntately, there is little published in the area of post-op complications, which is tragic if you are a patient assessing the risks of a spinal procedure. Thus, the lack of references cited below.

The following post-op complications are loosely ranked in terms of actual occurrence (after an artificial disc replacement procedure):

 

There are other complications that can and do occur post operatively. Additional post op risks include thrombophlebitis, lung problems, implant migration (including subsidence), spinal cord injury, transitional syndrome and pseudoarthrosis. A succinct summary article describing these conditions is found at:

If you are considering ADR as a surgical option, research these conditions to help you converse intelligently with your doctor(s). Visit Interactive Tutorials or Spine Research Sites to learn more.

Post-Op Recovery

Post-Op Recovery Chance Favors the Prepared Mind At this time, there are few papers or resources available to help patients prepare for ADR recovery. The best advice is to work very closely with your doctor (and staff) and prepare for each and every visit. As products are granted FDA approval, we expect to see more educational materials and papers made available to patients. Pain management after ADR is a real challenge for most patients. Since many people are on strong pain killers before surgery, it is difficult to make a transition to a chemical-free life. These complex issues are tough to sort out, but are handled nicely on a personal level on the interactive forums. However, these resources are helpful to help you frame the issues you should discuss with your doctor or other medical professionals.
