Welcome to ChiroGeek.com, a pop-up and ad-free site created and managed by Dr. Douglas M. Gillard, BS, DC, Associate Professor of Clinical Sciences, Published Spine Researcher, and former Coordinator of Radiology - Palmer West

Note: The pages on ChiroGeek.Com are best viewed with the latest versions of Google Chrome, Firefox, or Safari on a PC or MAC.

Please note that it is absolutely mandatory to read my disclaimer before viewing the pages on this website, and never act on any of the information you glean from these pages without first discussing it with your primary health care provider.

The information on this website is for educational purposes only. Furthermore, none of the opinions expressed by Dr. Gillard on this website or during his coaching sessions are those of Palmer College of Chiropractic, which is a completely separate entity and has nothing to do with this personal website.

The purpose of this website, which has been written in an easy-to-understand language, is to educate the layperson, healthcare profession student, and healthcare professional about the common causes of chronic back and leg pain, as well as the available evidence-based treatment options for these conditions.

My Philosophy

Because I consider myself a professional spine researcher (recently employed by the prestigious Steadman Philippon Research Institute and currently working with a world-class neurospine surgeon, Dr. Burak Ozgur, MD), a published author (read my recent publications), an Associate Professor of Clinical sciences, and a licensed chiropractor with 31 years' of experience, as well as the unfortunate victim of a botched microdiscectomy which left me with a significant permanent disability, I felt compelled to create a website based upon science (i.e., evidence-based) and the results of recent quality research as published in top-tier peer-review medical journals.

In other words, I'm not just some idiot spitting out unsupported statements on these pages. There are plenty of those idiots/quacks running wild on YouTube right now, so watch out for them! This stuff is my life, and I take great pride in putting logic, science, and research behind my writing as demonstrated by the numerous references that I have painstakingly placed within these pages. I like to think of myself as the "Mr. Spock" of spine-related on-line medical journalism.

I believe such responsible evidence-based medical journalism (i.e., supporting what you say by referencing quality medical research) should be the gold standard of which all healthcare websites and YouTube videos should adhere to. However, that is definitely not the case, for there are truly a lot of misleading healthcare websites and videos out there peddling all sorts of garbage, so please be very careful of what you read! Always make sure that the author of the page or video is using scientific references (or footnotes) to back up what he or she is saying and never act and anything without running it by your primary health care provider.

In Closing

I hope you enjoy this ad-free website and conquer your pain in the very near future.

Please feel free to e-mail me any short question that you may have, and I will try to answer it in a timely manner.

And finally, let's not forget that I do offer a very popular "Coaching Service" in which you and I will go over your images together (via GoToMeeting) and then formulate a plan of action based on my knowledge, experience, and the current medical literature, which I have full access to.

Radiologists Did a Poor Job at Picking out Common Pain Generators on MRI! [full story]

I've been saying for years how terrible many radiologists are at picking out common pain-causing disorders of the lumbar spine from MRI images, but now I have some evidence based proof that this is true. Herzog et al just (2017) published the results of their semi-diabolical study which sent a single patient, who was known to have three common lumbar spinal disorders (spondylolisthesis, spinal stenosis, and disc herniation) to 10 randomly-chosen radiology centers for MRI and report within a three-week period. These 10 reports were then analyzed. You would think that all these board-certified radiologists would have caught the three common problems and their reports would be at least somewhat identical, but this was far from the case! I'll let you read the full review in my research blog, but to give you an idea of how poorly these radiologists did as a group, here's a fact from the study: 60% of the radiologists completely missed the severe spinal stenosis at L2/3 and only 10% of them actually saw it and described it correctly!

XLIF Paper Submitted for Publication Consideration:

I just wrote and submitted the results of a very interesting experiment which was carried out by Dr. Burak Ozgur, MD (a prominent neurosurgeon in Newport Beach, California) and his team, to the Journal of Neuroscienc. The paper demonstrated that traditional XLIF cage packing techniques do not do a very good job in filling the gap between the top and bottom of the cage surfaces and the vertebral endplates. However, by using new surgical technology, we were able to demonstrate in this cadaver study that it is possible to add significantly (P<0.05) more bone graft material to cages, even though they were already in position. So what? it stands to reason that by adding extra bone graft material, you should get an increased rate of successful interbody fusion which is known to increase clinical outcomes, including patient satisfaction.

The Dangers of Discography:

I have added a new review to the "Spine Research Page" which discusses the classic Carragee discography study. As I have predicted for years, this award-winning study demonstrated that a needle-stick-injury to the disc significantly increases the chances of future herniation, degenerative disc disease, Modic change, and discopathy compared to discs that are not stuck with the needle.

The Spondylolisthesis Page Has Been Updated:

I have completely updated the General and the Isthmic portions of theSpondylolisthesis page and included new spine research which has actually changed my treatment opinions on the subject.

Dr. Gillard Begins Work with a New Spine Surgeon

Dr. Gillard has begun working with a new spine surgeon who is located in the Los Angeles area.

The first paper describes results of a new bone graft-loading system, as tested in a cadaver spine, which allows the surgeon to fill the fusion cage after the cage has been inserted into the disc space.

The hypothesis is that by filling the cage in situ, you will get a greater volume of graft material within the cage and better fusion mass/endplate contact, which theoretically should increase rates of fusion.

He will also be using select students to participate in the paper creation, which has some of the more research-oriented students quite excited about.
