Caring Medical - Where the world comes for ProlotherapyMRI causes Failed Back Surgery

Failed Back Surgery

Ross Hauser, MD
In this article, Ross Hauser, MD explains why MRI readings may lead to INCREASED incidents of failed back surgery syndrome.

When radiologists say we are doing too many inappropriate MRIs, and that research underestimates the true extent of how many inappropriate MRIs are ordered for back pain,1 we know there is a problem in helping patients with unspecific back pain.

When “more than 50% of the patients indicated that they would undergo spine surgery based on abnormalities found on MRI, even without symptoms,” we know that that there is a problem.

The biggest problem is that this treatment course is the standard of care.

The problem is, as pointed out in the research mentioned above and below:

Where is the evidence for all this? It is all around us in the medical literature.

MRI has little value in helping patients cure their back pain

In a recent study published in the New England Journal of Medicine doctors  questioned MRI’s usefulness as a frequently performed test during follow-ups in patients with known lumbar-disc herniation and persistent symptoms of sciatica. The association, they noted, between findings on MRI and clinical outcome is controversial, with several studies showing a high prevalence of disk herniation, ranging from 20 to 76%, in persons without any symptoms.

The doctors looked at patients who had MRI performed before treatment and after treatment in two groups. Group one had surgery and group two did not and received conservative care instead.

The two groups were divided, regardless of the treatment into two groups: 1) Favorable outcome after treatment. 2) Unfavorable outcome after treatment.

After one year they compared MRIs “before and after.”

What did the doctors conclude?

Nearly 1 in 3 back pain patients should not even get an MRI according to one report because it may lead to unnecessary spinal surgery. “MRI alone may provide insufficient or inaccurate information upon which to base surgical/technical decisions in about of 30% of cases (of back pain).”3

Despite this evidence, patients are lead to believe that the MRI is the final truth.

In a recent study, doctors found that a surprisingly high percentage of patients have misconceptions regarding their MRI diagnosis and their treatment of lumbar spondylosis (degenerative – osteoarthritic changes in the spine).

The researchers asked patients questions designed to assess patient understanding of the role of MRI  imaging in the diagnosis and treatment of low-back and leg pain, and patient perception of the indications for surgical compared with conservative management.

An amazing research paper appeared in May 2015. In this medical paper, doctors wanted to know what were the 100 most influential or frequently cited studies about lumbar spinal surgery.

Many would think the most frequently cited articles would be about spinal surgery techniques or spinal pain treatments. NO it is about positive readings on MRI in pain negative patients! Clearly the medical community recognizes that spinal surgery recommendations based on MRI finding are troubling.

Here is the findings:

The top two most cited papers were studies that questioned how to interpret an “abnormal” MRI in patients who had no pain and were written more than 22 years ago.7 Nothing has changed since.

With this evidence, we tell many patients we don’t need an MRI

When we see a new patient with back pain, they will often ask:  “Do I need to get a ‘fresh’ MRI?”

We do not advocate the use of MRI’s for diagnosing the cause of pain because the main reason surgeons perform spinal surgery is the above mentioned findings of abnormalities on MRI scans. As stated, most MRI findings have nothing to do with why the person has pain and this is the reason for most back surgery failures.

In one study, researchers noted that more than 85% of patients seen have low back pain that cannot be attributed to a specific disease or an anatomic abnormality and it is well known that imaging of asymptomatic patients often reveals anatomic abnormalities, such as herniated discs.

The same thing was noted by JC Andersen of the University of Tampa in his paper determining whether or not MRI should be ordered in treating athletes with back pain.

Despite the fact that low back pain MRIs made the top five list of overused tests and treatments, according to the American Academy or Family Physicians and the American College of Physicians, and despite the fact that lumbar spine scans have a poor track record of connecting findings to clinical signs and symptoms, the number of scans has risen dramatically.10

Asking patients what hurts has significant diagnostic value

In a new study looking at ways to minimize failed back surgery, doctors suggest that “Factors such as a lack of knowledge or recognition of the common structure specific pain referral patterns, poor clinical reasoning, unappropriate referral and predilection for popular management approaches also contribute to misdiagnosis and mis-management.”11

Further that doctors should broaden their approach in managing low back pain by using patient questionnaires and health quality of life surveys. 

The amazing summary of this paper? Let’s ask the patient!

In recent research, investigators found that talking to patients about their back pain could have significant diagnostic value. Doctors explored patient diagnosis in nerve root compression in men. Things that help doctors were answers to questions such as “pain worse in leg than in back,” and “a non-sudden onset.” 12 Things that could not be determined by an MRI.

Summary – MRI for back pain

Best evidence does not support the use of MRIs for patient surgical selection

One of the most difficult things to tell a patient with significant back pain is that the MRI may not be telling the true story. This, despite an abundance of research suggesting it is not possible to accurately predict who spinal fusion will or won’t work for, using standardizing radiological scans:

Reliance on MRI for determining surgical treatment for spinal pain has been shown to be faulty, inaccurate, and leads to unnecessary surgery. This is why it is very important that the patient seek an opinion from a doctor who performs a physical examination to determine the exact cause of pain.

In one research study, doctors said that nearly one in four patients who had a lumbar discectomy had positive scans for recurrent disc herniation following the surgery, the majority of which displayed no pain symptoms.

MRI validated disc herniation which did not cause pain or other symptoms was not associated with clinical consequences in two years following surgery. Clinically silent (patient’s not reporting) recurrent disc herniation is common after lumbar discectomy.

In other words doctors are telling each other that when they order a MRI within the first 2 years of discectomy, they should expect that the MRI will show abnormalities that are of no consequence to the patient and that they should not rush to surgery.15

At Caring Medical, we perform a physical examination on each and every patient, even those who bring in MRI or X-ray results, to determine the exact cause of pain. We then chooses the best course of Prolotherapy treatment to heal the injury and rid the patient of pain. The average patient receives 3-6 treatments spaced four weeks apart. So if your doctor prescribes an MRI, take caution. Your MRI could be your Failed Back Surgery cause. A physical examination is essential in diagnosing pain.
