tendinopathy: tendinitis or tendinosis?

Although most practitioners seem to be unaware of the fact, over the past several decades, medical research has conclusively shown that the major cause of “tendinopathy” is not Inflammation (aka “itis“).  The scientific studies have been leading medical researchers to the conclusion that although the immune system compounts that we collectively refer to as INFLAMMATION are probably present in tendinopathies; inflammation itself is rarely the primary culprit. 

So, if “itis” (inflammation) is not the primary cause of most of what we today refer to as ‘tendinitis’, what is?  Medical Research has shown us that the primary culprit is something called “osis”.   Thus the name, “tendon – osis” (tendinosis).  But this begs the question, what is osis?  The suffix “osis” indicates that there is a derangement and subsequent deterioration of the collagen fibers that make up the tendon. The truth is, even though doctors still use the term “tendinitis” with their patients, look on your EOB and you’ll see that their AMA-mandated Diagnosis Codes almost always indicate that the problem is “tendinosis” or “tendinopathy” (tendinopathy indicates an unspecified tendon problem).

Is the differentiation between “tendinits” and “tendinosis” really that important, or am I simply “splitting hairs” and making a big deal out of nothing?  Instead of answering that question myself, I will let one of the world’s preeminent orthopedic surgeons and tendon researchers answer it for me.

The information in the preceding paragraph (which, by the way, was not “new” when it was published well over a decade ago) is so important that it should be considered revolutionary.  The problem is that most of the medical community has, as Dr. Murrell stated above, “a limited understanding of tendinopathies“.  Why?  Why do more doctors not grasp what is going on with the majority of Tendinopathies?  Why does most of the medical community continue to ignore their own profession’s scientific data — over two decades worth of data —- and continue to treat tendinopathies with drugs and surgery? 

Unfortunately, if you are dealing with a chronic tendinopathy, you are probably being treated using a model that is at least 25-30 years behind the times as far as the medical research is concerned (HERE)!  You think not?  Read what Dr. Warren Hammer, board certified Chiropractic Orthopedist (in practice since the late 1950′s), had to say about the subject in a 1992 column from Dynamic Chiropractic:

To decipher this into plain English; if you injure a tendon, either traumatically or repetitively, you end up with fiber disorientation that looks frayed, tattered, and tangled, instead of a normal tendon that is made up of uniformly wavy and parallel fibers. 

If your doctor is still treating you for tendinitis and not tendinosis (using NSAID medications and CORTICOSTEROIDS), he / she is caught in a time warp.  Anti-inflammatory drugs are known to deteriorate collagen-based tissues (this is why they are — or should be — rationed by your doctor).  Plainly stated, the vast majority of tendinopathies are not inflammatory conditions (itis)!   They are tissue derangements that wind up causing degeneration of the collagen fibers (osis)!   For information about effectively treating tendonosis, visit our page specifically dedicated to helping people with all sorts of TENDINOSIS.
