Failed back surgery syndrome treatment options
Ross Hauser, MD.
- injection of steroid appears to be effective in only a minority of patient
- doctors should not recommend surgery if patients exhibit no pain despite positive MRI finding
- as lumbar surgery continues to grow in prevalence, so will the number patients suffering from (failed surgery)
- patients complained of “persistent back and/or leg pain despite having “completed spinal surgery
Spinal surgery cannot only fail to relieve pain; it may in fact cause more pain. Most of the time the surgery itself is causing more complications than it fixes. For example in a discectomy (removal of the disc), the surgeon must spread muscle and cut various ligaments in order to perform the surgery. The surgery itself can potentially lead to ligament laxity and instability of the spine. Further removal of a disc or fusion at one level can lead to disc herniation at the same level or at different levels in the future. It is very common for Prolotherapists to see a patient with “one level fixed,” while another segment of the spine is now unstable, degenerated, and causing pain. Another way surgery causes harm is that in a discectomy, a large portion of the disc remains behind. This is the portion that, if removed, will cause great risk to the patient. The remaining disc can be as much as 40% of the original disc and it can also re-herniate.
Spinal surgery is very radical, it injures and damages a lot of tissue not even associated with the painful area. So what if there is pain following surgery? What are the options?
In recent research, doctors noted that failed back surgery patients were showing up at doctor’s offices in “overwhelming numbers.” These patients complained of “persistent back and/or leg pain despite having “completed spinal surgery.” They also noted “As lumbar surgery continues to grow in prevalence, so will the number patients suffering from (failed surgery).”
To fix the patient: ”The most invasive treatment option, short of revision surgery, is spinal cord stimulation. This intervention has a number of studies demonstrating its efficacy and cost-effectiveness in this population. Finally, revision surgery may be used when indicated such as with progressive neurological impairment or with issues regarding previous surgical instrumentation.”1
Therefore it is not uncommon for people to undergo a complicated spinal surgery only to be left with chronic low back pain. The diagnosis for this scenario is “failed back surgery syndrome,” or FBSS.
Failed back surgery caused by MRI
“Nearly one-fourth of patients undergoing lumbar discectomy had positive scans for recurrent disc herniation following the surgery, the majority of which were asymptomatic. 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.
When obtaining MRI evaluation within the first 2 years of discectomy, providers should expect that radiographic evidence of reherniation may be encountered and that treatment should be considered only when correlating radicular symptoms exist.”2
If the patient does not complain of back pain – but the MRI shows herniated disc – Do not recommend surgery!
Here is what researchers in Germany found when they tested steroid injection in patients with chronic back and radicular pain after surgery: “Of 479 patients who underwent microsurgical lumbar disc surgery, 69 had persistent radicular pain. . . injection of steroid achieved pain reduction of at least 50% in 26.8% of these patients. The success rate was higher (43%) in patients without a recurrent disc herniation. “Here is the big finish: ” injection of steroid appears to be effective in only a minority of patients with radicular pain persisting after disc surgery…” PLEASE NOTE 479 PATIENTS – 69 HAD persistent radicular pain – ABOUT 15%.1
In other words – if the patient does not complain of back pain – but the MRI shows herniated disc – leave the patient ALONE! If low back surgeries are so unsuccessful, why do surgeons continue to perform them? The main reason is because they find abnormalities on MRI scans – as mentioned above.
Ironically most MRI findings have nothing to do with why the person has pain and this is the reason for most back surgery failures. Nearly one in three 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
“Recurrence of back or leg pain after discectomy is a well-recognised problem with an incidence of up to 28%. Once conservative measures have failed, several surgical options are available and have been tried with varying degrees of success….The debate around which procedure is the most effective for these patients remains controversial. Our results show that less invasive posterior lumbar interbody fusion (LI-PLIF) is as effective as any other surgical procedure. However, given that it is less invasive, we feel that it should be considered as the preferred option.”2
Note that the above study cites 28% rate of post-surgical pain. The researchers also note that controversy exists over the best revision surgery for pain after surgery. Their conclusion is that surgeons may as well choose the least invasive surgery since there’s no one revision surgery that is better than the other. As mentioned above, surgery of any kind interferes can cause harm to soft tissue, revision surgery is likely not the best answer.
“Spinal cord stimulation has become a widely used and efficient alternative for the management of refractory chronic pain that is unresponsive to conservative therapies. Technological improvements have been considerable and the current neuromodulation devices are both extremely sophisticated and reliable in obtaining good results for various clinical situations of chronic pain, such as failed back surgery syndrome, complex regional pain syndrome, ischemic and coronary artery disease. This technique is likely to possess a savings in costs compared with alternative therapy strategies despite its high initial cost. Spinal cord stimulation continues to be a valuable tool in the treatment of chronic disabling pain.”3
When surgery fails, when narcotics fail, electrical technology is brought in. The spinal cord stimulator provides a small electric current to the person’s spinal cord so the impulses of pain and injury are lessened. In most patients we see, the spinal cord stimulator does not replace the need for narcotic medication. Additionally, a foreign device is placed in the body, which is nearly never the best option.
Mind over body?
“Mindfulness-based stress reduction (MBSR) is frequently used for pain conditions. While systematic reviews on MBSR for chronic pain have been conducted, there are no reviews for specific pain conditions. Therefore a systematic review of the effectiveness of MBSR in low back pain was performed….This review found inconclusive evidence of effectiveness of MBSR in improving pain intensity or disability in chronic low back pain patients. However, there is limited evidence that MBSR can improve pain acceptance.”4
In other words, just live with the pain. Mental strength can help, but the reality is that there is an underlying cause of the pain that needs to be addressed. So what are other options for pain after back surgery?
Comprehensive Prolotherapy for failed disc surgery: realistic goals
Comprehensive Prolotherapy is a treatment designed to strengthen weakened soft tissue in the spine and bring stability to the area through injections, not surgery. More stability, less unnatural movement, less pain. We recommend a consultation for those on narcotics and those with spinal cord stimulators. In the case of spinal stimulators, we ask patients to bring in their X-rays showing exactly where the spinal cord stimulator is placed. As long as we can see where the stimulator electrodes are located we can safely do Prolotherapy.
Prolotherapy attacks the problems of a damaged spine instead of suppressing the symptoms. It offers a fix when all else fails. While Prolotherapy is an alternative to disc surgery, it can also help when disc surgery has already occurred yet failed to address the root issue.

How does Prolotherapy help radiculopathy?
Radiculopathy by definition means a nerve is being compromised leading to symptoms in the extremity. We find that 90% of people coming in with the diagnosis of radiculopathy (Lumbar Radiculopathy) do not have a pinched nerve. The majority has referred pain down the extremity (leg or arm) from a ligament injury in their pelvis, lower back, neck, or upper back. Three to six Prolotherapy sessions and the majority of these pains subside. For the other 10 percent that 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 the case of a true pinched nerve, most Prolotherapists will get the person some pain control while the Prolotherapy is working. 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 best approach, in our opinion, is to give a steroid injections right around where the disc herniation is located. This is called a nerve block. 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 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. Up to three of these are done. At the two-week point, sometimes another Prolotherapy session is done. Up to four Prolotherapy sessions are sometimes needed. The above approach has been used at Caring Medical Rehabilitation Services 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!
