Ligament laxity and spinal instability | Back pain treatments
Spinal instability can be at the root of many back pain conditions but the cause of the instability can be confusing and complex.
In this article we will provide information on: failed back surgery syndrome, non-surgical treatment of lumbar radiculopathy, lumbar disc herniation, sacroiliac joint pain treatment, and obesity and depression and their effects on low back pain as well as discussing the challenges of identifying spinal instability caused by spinal ligaments.
Identifying nonspecific back pain
Recently researchers in Germany discussed the problems of assessing the true cause of back pain. To summarize their findings, the researchers noted that:
- The most examined spinal problem is low back pain and low back pain for the most part is caused by a nonspecific problem that is difficult to diagnosis.
- Inflammation of the spine is not as widespread. Only a small amount of patients have axial (low back sacroiliac joint) inflammation as the major cause of their back complaints with chronic inflammatory back pain as the most prominent clinical feature of spondyloarthritis (inflammatory/rheumatoid arthritis)
- Numerous diseases such as:
- degenerative disc disease,
- degenerative changes in the intervertebral (facet) joints and the associated ligaments,
- spinal instability,
- herniation of the intervertebral disc,
- and spinal stenosis
- have to be differentiated in interpreting imaging of the spine. (Ross Hauser MD has written on article on this site on how the MRI is a risk factor for failed back surgery)1
When a patient comes into Caring Medical we look for the familiar characteristic features of a patient with spinal instability. This helps us determine the role of discs and ligaments in the patient’s complaint of spinal instability.
1. The patient reports their back cracks a lot
Typically a patient will report that they hear a crack every time they turn over in bed or stretch out their back. This can be a tell tale sign of spinal instability. With regular movements such as these, it isn’t normal for vertebrae to shift enough to make a cracking sound, also known as crepitation.
2. Patient reports that they get frequent chiropractic adjustments
Needing frequent chiropractic treatments or therapy to relieve chronic pain is not typical. This means that the patient is suffering from constant dislocations of the vertebrae. It is likely that the reason the vertebrae continue to move out of position is ligament laxity, or the inability of ligaments to hold the spine in place.
When capsular ligaments and other soft tissues along your spine stretch out, the vertebrae are able shift out of alignment. Even if you have them put back in place through repeated care and adjustments, the ligaments still remain loose and can allow for repeated shifting.
3. Patient continuously self-manipulates
Self-manipulation of the spine is very abnormal finding, yet is a common thing that we see. Whenever a new patient comes to Caring Medical for neck or low back pain, it is highly likely that they will tell us they crack their back or neck habitually.
Self or chiropractic manipulation has the potential to further loosen the spinal ligaments and cause more instability.
4: Intermittent pain down the arm or leg
Spinal subluxations (slipped/herniated disc) can pinch on nerves as they exit the spinal cord. The pain of the pinched nerve is not constant but instead only occurs when the vertebrae shift and pinch on the nerve. This is usually a good prognostic indicator for ligament damage as the cause of spinal instability.
5: Tightness or spasm in the neck and back muscles, even at rest
What causes muscle spasms in the back? It isn’t normal to get knots, trigger points, or tender points in muscles. Neck, upper back, or lower back muscle spasms are a sign of spinal instability. The reason these painful spasms do not go away is because they are trying to stabilize the spine. The tightness and spasm are a clue that the ligaments have become weakened and injured. When there is ligament instability there is spinal instability the surrounding muscles contract as a way to help keep stability.
What is the answer for patients with back pain?
A recent paper examined the top 20 research studies of 2015 that had the most impact on family practice doctors. Among the top 20 was “avoiding early imaging (MRIs et al) and not adding cyclobenzaprine or oxycodone to naproxen for patients with acute low back pain; and encouraging patients with chronic or recurrent low back pain to walk.”2
At Caring Medical we have to agree that concerns about treatment plans based on MRIs, painkillers and lack of movement in patients would back pain is something that needs to be looked into and corrected.
In a recent study, researchers followed
- Fifty patients with lumbar spondylolisthesis,
- Fifty patients with stenosis, and
- Fifty patients with disc herniation who had symptoms persisting after 6 weeks of medical management and who were eligible for surgical treatment were followed after deciding on nonsurgical treatment.
The non-surgical treatment was:
- Spinal steroid injections,
- physical therapy,
- muscle relaxants,
- anti-inflammatory medication,
- and narcotic oral agents.
The maximum health gain in back pain, leg pain, disability, quality of life, depression, and general health state did not achieve statistical significance by 2 years of medical management, except for pain and disability in patients with disc herniation and back pain in patients with lumbar stenosis.
- Eighteen patients (36%) with spondylolisthesis,
- 11 (22%) with stenosis, and
- 17 (34%) with disc herniation eventually required surgical management due to lack of improvement.
In all cases, comprehensive medical management included spinal steroid injections, physical therapy, muscle relaxants, anti-inflammatory medication, and narcotic oral agents was not cost effective and the patients went on to surgery.3
Sometimes a patient will come in with a list of muscle relaxers they have been prescribed. The more common names and types they come in with are: Diazepam (Valium), Carisoprodol (Soma), which is habit forming. These and other drugs given for muscle spasms/relaxation are part of a class of drugs known as Benzodiazepines – anxiety medication / tranquilizers.
In new research doctors found that muscle relaxants do provide temporary benefit for acute back pain. But for long-term chronic low back pain problems – there is no evidence for the efficacy of benzodiazepines.4
Physical therapy for low back pain
Doctors examined the the work-related load experienced by physiotherapists and the occurrence of the musculoskeletal system overload in providing physical therapy. A job requiring stooping, lifting, carrying loads and multiple repetitions of the same movement patterns leads to overloading the musculoskeletal system. The most common musculoskeletal complaints were as follows: 70 physiotherapists (64.8% ) reported low back pain, 60 (55.6% ) cervical pain, and 34 (31.5% ) pain in the wrists and fingers.5
Physical therapy is the major component of the conservative approach to low back pain. The Caring Medical experience is that the results are often disappointing.
Doctors in the United Kingdom came to a similar conclusion when they could not find clinical research evidence that physical therapy (therapist-delivered interventions) provided benefits.10
Many acute back injuries get better by themselves. Many of these patients do take some PT, whether formally at a Physical therapy facility, or more haphazardly at a chiropractor’s office, but it’s difficult to tell whether the results are any better or faster than they would be without the PT. Cases in which there is muscle weakness should have a prescribed regular program of strengthening exercises.
Physical therapists may suggest the balance ball, yoga, and pilates which placing stress on healing low back ligaments. Prolotherapy doctors usually recommend exercises such as side plank, supine plank, and regular planks. In these, as in holding yoga poses, there is no movement that stress the spinal ligaments.
Prolotherapy for back pain
There is plenty of research to support the use of Prolotherapy for back pain (especially lumbar pain), here are some of the research summaries.
- Prolotherapy can be an effective treatment for low back pain from ligament damage when performed by a skilled practitioner.5
- Prolotherapy can provide significant relief of axial pain (soft tissue damage) and tenderness combined with functional improvement, even in “failed back syndrome” patients.6
- Prolotherapy provides better and longer lasting relief than injection with anesthetics alone (see below on epidural steroid injections).7
Citing our own published research in which we followed 145 patients who had suffered from back pain on average of nearly five years, we examined not only the physical aspect of Prolotherapy, but the mental aspect of treatment as well.
- In our study, 55 patients who were told by their medical doctor(s) that there were no other treatment options for their pain and a subset of 26 patients who were told by their doctor(s) that surgery was their only option.
- In these 145 low backs, pain levels decreased from 5.6 to 2.7 after Prolotherapy; 89% experienced more than 50% pain relief with Prolotherapy; more than 80% showed improvements in walking and exercise ability, anxiety, depression and overall disability; 75% percent were able to completely stop taking pain medications.8
Ligament laxity and spinal instability
The first step in determining in whether Prolotherapy will be an effective treatment for the patient is to determine the extent of ligament laxity or instability in the lower back by physical examination. The examination involves maneuvering the patient into various stretched positions. If weak ligaments exist, the stressor maneuver will cause pain. Pain here is an indicator that Prolotherapy can be very effective for the patient.
When identified as a problem of ligament weakness causing instability, low back pain is one of the easiest conditions to treat with Prolotherapy. Ninety-five percent of low back pain is located in a 6-by-4 inch area, the weakest link in the vertebral-pelvis complex.
At the end of the spine, four structures connect in a very small space which happens to be the 6-by-4 inch area. The fifth lumbar vertebrae connects with the base of the sacrum This is held together by the lumbosacral ligaments. The sacrum is connected on its sides to the ilium and iliac crest. This is held together by the sacroiliac ligaments. The lumbar vertebrae is held to the iliac crest and ilium by the iliolumbar ligaments. This is typically the area treated with Prolotherapy for chronic low back pain.
The diagnosis of ligament laxity in the lower back can be made relatively easily. Typical referral pain patterns are elicited-the sacroiliac ligaments refer pain down the posterior thigh and the lateral foot, the sacrotuberous and sacrospinous ligaments refer pain to the heel. The iliolumbar ligament refers pain into the groin or vagina. Iliolumbar ligament sprain should be considered for any unexplained vaginal, testicular, or groin pain. Please see our companion article which talks about non-surgical treatment of lumbar radiculopathy.
The most common cause of unresolved chronic low back pain is injury to the sacroiliac ligaments which typically occurs from bending over and twisting with the knees in a locked, extended position. This maneuver stretches the sacroiliac ligaments, placing them in a vulnerable position.
Prolotherapy Treatment to the low back
Prolotherapy injections for chronic low-back pain
At Caring Medical Regenerative Medicine Clinics, we utilize comprehensive Prolotherapy as our treatment of choice because of our own documented research. We found that in 145 patients, pain levels decreased from 5.6 to 2.7 after Prolotherapy; 89% experienced more than 50% pain relief with Prolotherapy; more than 80% showed improvements in walking and exercise ability, anxiety, depression and overall disability; 75% percent were able to completely stop taking pain medications.8
If our study, mentioned above, was solely based on getting 75% of patients off their pain medications, that would be wildly successful in itself. But the fact that Prolotherapy was able to strengthen the patient’s spines and decrease overall disability and return these people to a normal lifestyle. That is not pain management, that is a pain cure. the medical research, doctors found that Intra-articular prolotherapy provided significant relief of sacroiliac joint pain, and its effects lasted longer than those of Epidural Steroid Injections. Also please review our article on facet joint injections by Dr. Tim Speciale.
Here is a more detailed review of our published paper in the Journal of Prolotherapy:
We looked at :
- One hundred forty-five patients, who had been in pain an average of four years and ten months, were treated quarterly with Prolotherapy. This included a group of 55 patients who were told by their medical doctor(s) that there were no other treatment options for their pain and a subset of 26 patients who were told by their doctor(s) that surgery was their only option.
- Patients were contacted an average of 12 months following their last Prolotherapy session and asked questions regarding their levels of pain, physical and psychological symptoms and activities of daily living, before and after their last Prolotherapy treatment.
In these patients:
- 89% experienced more than 50% pain relief with Prolotherapy;
- more than 80% showed improvements in walking and exercise ability, anxiety, depression and overall disability;
- 75% percent were able to completely stop taking pain medications.7
