Prolotherapy and non-surgical treatment of lumbar radiculopathy

non-surgical treatment of lumbar radiculopathy

Ross Hauser, MD
In this article, Ross Hauser, MD discusses Prolotherapy as a non-surgical treatment of lumbar radiculopathy.

The best conventional medicine has to offer for lumbar disc herniation and associated lumbar radiculopathy are surgeries that do not work that well.

Let’s look at research from August 2017 appearing in the British journal of neurosurgery:

“Though different techniques have been successfully employed in the treatment of recurrent lumbar disc herniation, the one which should be considered most ideal has remained a controversy, (minimally invasive surgical techniques).”

“In view of the currently available data and evidence, minimally invasive techniques for revision of recurrent disc herniation do not really appear to be superior to the conventional open surgical approaches and vice-versa. Spinal fusion should not be undertaken in all recurrences but should only be considered as an option for revision when spinal instability, spinal deformity or associated radiculopathy is present.”(1)

  • In other words, the best conventional medicine has to offer for lumbar disc herniation and associated lumbar radiculopathy are surgeries that do not work that well. Please see my article: Non-surgical treatment of a herniated disc.

Unfortunately, treatments with less than great results in the medical literature are given until “all has failed,” and the patient is sent to surgery. Please see this supporting article on our website: failed back surgery risk factors.

Lumbar Radiculopathy can be confusing. In recent research doctors call some cases “so-called Lumbar Radiculopathy” because it is not radiculopathy

In our experience, many individuals who are diagnosed with lumbar radiculopathy, are more likely to have a “pseudo” radiculopathy. This is a condition where radicular pain comes and goes with changes in activity or changes in position, pinching the nerve intermittently.

L5 lumbar instability causing sciatica pain

If this is the case, then we can look for an underlying spinal instability caused by ligament injury to the lumbar spine which is often overlooked in pre-surgical consults. If ligament injury is there, we can offer the patient Prolotherapy as a non-surgical means to repair the damage, strengthen the spine, alleviate the pain and symptoms of lumbar radiculopathy.

Doctors writing in the Swiss Medical Review (Revue médicale suisse) highlight:

A lumbar disc herniation is a condition frequently encountered in primary care medicine. It may lead to a “compressed nerve,” leading to a nerve root irritation,“a so-called radiculopathy”, with or without a sensorimotor deficit (varying levels of loss of sensory or motor skills).

The majority of lumbar disc herniations can be conservatively treated with physical therapy, analgesics (pain killers), anti-inflammatory therapy or corticosteroids, which may be eventually administered by infiltrations (various injection or infusion techniques).

If a clinico-radiological (MRI and other scans) correlation is present and moderate neurological deficit appears suddenly, if it is progressive under conservative treatment or if pain is poorly controlled by well-conducted conservative treatment performed during four to six months, surgery is then recommended.(2)

What is described above is the typical road to surgery.


Researchers at Penn State University writing in the medical journal Clinical spine surgery found:

Doctors writing in the Journal of back and musculoskeletal rehabilitationnote that even one epidural steroid injection can be effective in the short term, suggesting radiculopathy can be a transient condition that can be treated without surgery.(4)

Back to the Penn State research, the doctors also found that patients with pain with lumbar extension (most commonly a popular exercise where patients “stretch” their spine by bending backwards) was negatively and significantly related to length of relief duration from the caudal epidural steroid injections.

  • The average length of relief duration is 38.37 weeks for individuals without painful lumbar extension and 14.68 weeks for individuals with painful lumbar extension. The mean length of relief following a caudal injection is reduced by 62% in patients who exhibit pain with lumbar extension.(3)

Epidural steroid injection

It is interesting that patients who failed to have their symptoms managed with epidural injections are treated with epidural injections before and after failed surgery for radiculopathy, only with stronger and more frequent doses.

Epidural steroid injections ease pain temporarily by reducing the size of stressed nerve roots. However concerns over short-term gain long-term costs in the use of epidural steroid injection side-effects have been noted.

Epidurals are part of the common treatments for light cases of lumbar radiculopathy which usually include NSAIDs (non-steroidal anti-inflammatory drugs), physical therapy, or chiropractic treatment. Although many patients respond very well to these treatments, they are only temporary fixes that can help ease the pain and only relieve some symptoms of the condition.

Further, research in the Journal of the American Medical Association, JAMA said that oral steroids as compared to placebo, offered minor improvement in function but did not improve pain conditions.(5)

Diagnosis and Treatment of Lumbar Radiculopathy

Many patients will be sent off for physical therapy. These patients often see mixed results.

Physical Therapy:

  • Research in the medical journal Spine reported: “Physical therapy is commonly sought by people with lumbar disc herniation and associated radiculopathy. It is unclear whether physical therapy is effective for this population.” The research did find that for up to 10 weeks physical therapy provided symptom relief, but the effects were not long-lasting.(6)


Lower Back Prolotherapy


Back to Pseudo-Radiculopathy | Structural radiculopathy vs intermittent or transient radiculopathy | Realistic treatment options with Prolotherapy

  • Testing for Radiculopathy: An EMG or nerve conduction study seeks to determine if the nerves are getting pinched. If the nerve is getting pinched then we have to figure out is it a structural radiculopathy (constant pain) or is it a radiculopathy that’s intermittent (pain and numbness comes and goes).

In utilizing Prolotherapy as a treatment, diagnosing lumbar radiculopathy as an intermittent of transient pain, as mentioned above, requires a physical examination, manipulation, and palpitation of the suspect area. During the physical examination we are looking for  underlying ligament injury to the lumbar spine. When the ligaments become weaker and allow for more movement than normal the vertebrae then move excessively, rotate, and the nerve can get pinched. This pinching causes extreme pain down the legs and feet. If the lumbar radiculopathy is intermittent, then this pain will be occasional or intermittent. Prolotherapy to the injured and weakened areas will stabilize the lumbar vertebrae. Intermittent radiculopathy generally responds very well to Prolotherapy. Three to six Prolotherapy sessions and the majority of these pains subside.

For the people who have a true radiculopathy the following is typically present:

  • Crippling pain.
  • The MRI shows an acute herniated disc
  • The MRI finding is consistent with the person’s symptoms and exams
  • The EMG collaborates the MRI

In our office when a person with structural or true radiculopathy comes in, and we think we can help, we may offer nerve blocks with steroids along with the Prolotherapy. If the vertebrae is rotated and that is what is causing the problems of pinched or compressed nerves, and we are going to try to rotate it back with Prolotherapy, we may offer nerve blocks because Prolotherapy to work effectively will need time. Certainly a lot less time than surgical repair recovery. The person with a true radiculopathy needs to decrease the inflammation of the disc material pressing on the nerve while the Prolotherapy helps stabilize the herniated areas.

The key is time. When there is the presence of bone spurs and they are pinching on the nerves a person may be tempted try decompressive laminectomy or other surgical procedure.

In the case of a true pinched nerve, most Prolotherapists will get the person some pain control while the Prolotherapy is working.

  • A nerve block can be performed where the disc is herniated.
  • Sometimes an epidural is done, but we like putting the medication directly where the problem is located.
  • The person is also prescribed muscle relaxers and rarely oral steroids. These steps are only immediate-level treatments.
  • Simultaneously, Prolotherapy works on the long-term cure. Yes, the steroids may block some of the Prolotherapy effect, but the person needs immediate pain relief.
  • A medication to help sleep is also warranted sometimes.

Obviously, the person gets Prolotherapy to the areas.

  • The person is seen in follow-up in one week. At this time if they still have a lot of pain, then another steroid injection is given to the painful area.
  • At the two-week point, sometimes another Prolotherapy session is done.

Four to six Prolotherapy sessions are sometimes needed. The above approach has been used at Caring Medical for years. It has kept a lot of people out of surgery.

In our experience, the above approach even with herniated discs is around 90% successful. Of course, we have our handful of cases that have needed surgical consultation and surgery. We are grateful the surgeons are there for back-up. Even for an acute herniated disc, the surgeon is second-line therapy, or the person with a pseudo- or true radiculopathy the treatment of choice is Prolotherapy.

Cervical and Lumbar radiculopathy Prolotherapy Results

Our research: Published research from Caring Medical and Rehabilitation Services

In addition to the in-house data analyzed from consecutive cervical and lumbar radiculopathy cases, Caring Medical published research in the Journal of Prolotherapy demonstrating the effectiveness of Prolotherapy for unresolved back pain.

In our research, we reported on 145 patients who experienced low back pain an average of 58 months, who were treated on average with four sessions of dextrose (12.5%) Prolotherapy, quarterly, at a charity clinic.

The patients were contacted on average 12 months after their last Prolotherapy session.In these patients:

  • pain levels decreased from 5.6 to 2.7 (numerical rating scale NRS , 1-10 scale);
  • 89% experienced more than 50% pain relief

Results were similar in the patients who were told by at least one medical doctor that there was no other treatment option (55 patients) or that surgery was the only option (26 patients).(7)

The approach to back pain used in these studies was the foundation used in our clinics today. You can read more about the regenerative methods to treating spine pain conditions here.
