Cervical Neck Pain | Cervical Neck Instability

Ross Hauser, MD

In our practice, we continue to see a large number of patients with a myriad of symptoms related to cervical neck instability including severe pain, problems of balance, headaches, and loss of motion. These people have been told that their problem is a problem of degenerative cervical disc disease. After years of prolonged pain and conservative care options such as chiropractic, massage, physical therapy, anti-inflammatories, pain medications, cortisone injections, that eventually fail, the only recourse, these people are told, is surgery.

Cervical neck instability is very treatable with Prolotherapy, see our main page Prolotherapy for neck pain and cervical instability for more information.

Surgical recommendations sound like a good idea. The way the surgery is described makes sense that it may offer a solution. Cut away the cervical vertebrae bone from the nerves in a decompression – cervical fusion surgery, or replace the disc with an implant. But if these surgical options make sense, why were they not offered in the first place? The answer to that question is explained in the following articles:

Few have ever been told that their cervical ligaments need to be repaired.

Some of the most debilitating conditions attributed to problems in the neck are those due to cervical instability caused ligament laxity. The ligaments that hold the cervical vertebrae in alignment can be damaged via a sudden trauma, such as a whiplash or concussion, or through the slow stretching of ligaments, known as creep. (If you are suffering from whiplash please read this article next Whiplash and whiplash-associated disorders, please read this article if post-concussion syndrome is an issue for you.)


CREEP – cervical degenerative ligament disease

When spinal ligaments are exposed to continued compression or stress, they “Creep.” Creep is a medical condition that results from the deformity or elongation of the ligaments that hold the cervical spinal vertebrae in place. Creep can be caused by prolonged or years worth of bad posture, including the forward head posture. If bad posture is a chronic problem, the ligaments will stretch to the point of no return. In our neck, we have seven vertebrae that are held together by ligaments that can be vulnerable to CREEP.

Cervical neck instability is a problem of cervical ligaments

Without addressing the cervical ligament laxity, conditions that originate from joint instability can wreak havoc on a patient’s life in the form of chronic headaches, migraines, neck pain, TMJ syndrome, ear and mouth pain, to name a few.

There is much overlap in the symptoms caused by cervical instability and CREEP, and especially upper cervical instability (C0-C2): cervicocranial syndrome, atlanto-axial instability, whiplash, post-concussion syndrome, and vertebrobasilar insufficiency.

Cervical radiculopathy due to a pinched nerve in the neck can cause excruciating, burning pain that radiates into the arms and hands. We know cervical instability causes the facet joints to move too much and this can cause nerves to be pinched, among other symptoms. This movement can clearly be seen by using Digital Motion X-ray (DMX) technology.

Cervical instability conditions symptoms overlap

 


The concept of ligament laxity or cervical neck instability being caused by ligament damage is not so simple for doctors to understand. This may be why patients with neck problems walk around for years without hope or optimism that their problems can be solved.

An amazing study came out of the University of Waterloo in Canada and was published in the November 2017 edition of the Spine Journal.(1) Briefly here was the problem and the goal of the study:

Treating cervical ligaments

Throughout this article, I will refer back to research that our Caring Medical research team has published. In 2014 headed by Danielle R. Steilen-Matias, PA-C, we published these findings in The Open Orthopaedics Journal.(2)

The capsular ligaments (the ligaments of the joint capsule) are the main stabilizing structures of the facet joints in the cervical spine and have been implicated as a major source of chronic neck pain. Such pain often reflects a state of instability in the cervical spine and is a symptom common to a number of conditions such as disc herniation, cervical spondylosis, whiplash injury and whiplash associated disorder, post-concussion syndrome, vertebrobasilar insufficiency, and Barré-Liéou syndrome.

When the capsular ligaments are injured, they become elongated and exhibit laxity, which causes excessive movement of the cervical vertebrae.

Therefore, we propose that in many cases of chronic neck pain, the cause may be underlying joint instability due to capsular ligament laxity. Furthermore, we contend that the use of comprehensive Hackett-Hemwall Prolotherapy appears to be an effective treatment for chronic neck pain and cervical instability, especially when due to ligament laxity. The technique is safe and relatively non-invasive as well as efficacious in relieving chronic neck pain and its associated symptoms.

Identifying what is happening in the cervical spine, why ligaments are not even thought ofForward Head Posture

Physical therapists in Belgium wrote in the medical journal Manual Therapy, “Classifying nonspecific neck pain patients into subgroups based on clinical characteristics might lead to more comprehensive diagnoses and can guide effective management.” The subgroups were:

While these symptom classifications should be obvious signs of a patient in distress, the cause of the problems are not so obvious.

Cervical instability can be difficult to diagnose for the average practitioner. This is largely due to the low reliability and validity of radiographic studies including functional (motion) radiographs and many clinical examination measures that are still under debate and are rather questionable.

Unfortunately, there is often no correlation between the hypermobility or subluxation of the joint (excessive movement of the vertebrae), clinical signs or symptoms, or neurological signs or symptoms. Sometimes there are no symptoms at all which further broadens the already very wide spectrum of possible diagnoses for cervical instability.

In one study from the Department of Neuroradiology at the University of Munich, “healthy” volunteers who experienced no neck pain or headaches had  MRI’s that showed so many things wrong that the investigators had to conclude that the MRI had “limited diagnostic value in patients with whiplash-associated disorders.” Why? because MRI cannot show the problems of the cervical ligaments. (4)

Surgical treatments for Cervical Instability – Disc, disc, disc

In medicine, there are universally accepted equations. When pain cannot be controlled using conservative treatments including physical therapy, chiropractic, and pain medications, there has to be a surgical recommendation. 

In neck and spine surgery, doctors focus on degenerative disc disease and its treatment,   anterior cervical discectomy and fusion and cervical decompression surgery to remove whole or part of the cervical vertebrae to allow space on compressed nerves and to fix the instability by fusing vertebral segments together. In the case of C1-C2 instability, these two vertebrae are fused posteriorly (behind) to limit their amount of movement.  The goal is to limit pressure on the nerves.

However, it may limit motion to such an extent that patients become completely unable to move that portion of their neck. In addition, fusion operations can accelerate the degeneration of adjacent vertebrae as the motion in the neck is distributed more on these tissues.

The rush to surgery is based on the immediate goals of the patients, that is the alleviation of pain. Spinal cervical fusion and decompression seem to offer a solution – short term. This is supported in the medical literature. In one study in the medical journal Spine (Sept 2013), patients with cervical radiculopathy, treated with surgery and physiotherapy resulted in a more rapid patient improvement during the first year after surgery, with significantly greater improvement in neck pain and global assessment scores compared to physiotherapy alone.

However, the differences between the groups decreased after two years. In this paper where surgery was touted as being so successful – the researchers concluded: “Structured physiotherapy should be tried before surgery is chosen.”(5After two years, the same result between physical therapy and surgery was seen – no difference in the outcome.

In a more detailed look at the results of the above study, the researchers looked at the factors affecting the outcome of surgical versus nonsurgical treatment of cervical radiculopathy.

They wanted to analyze factors that may influence the outcome of anterior cervical decompression and fusion (ACDF) followed by physiotherapy versus physiotherapy alone for treatment of patients with cervical radiculopathy.

They wrote that an understanding of patient-related factors affecting the outcome of cervical surgery is important for preoperative patient selection.

Sixty patients with cervical radiculopathy were randomized into two groups: One group had the surgery and the physiotherapy, one group had the physiotherapy alone.

The people who had the surgery had a favorable outcome if

The doctors report that there were no factors that positively influenced a favorable outcome in the physiotherapy alone group.

This is why we see many patients who had a cervical spinal fusion include symptoms reflective of cervical adjacent segment disease with a recommendation to revision surgery that includes more include fusion, laminoplasty, and disc replacement.

 

Stabilizing the unstable neck – the case for treating ligaments with Prolotherapy

Back to our 2014 research headed by Danielle R. Steilen-Matias, PA-C, published in The Open Orthopaedics Journal. Here we outline that the problems of the cervical neck are not always problems of degenerative disc disease but problems of degenerative ligament disease. This explains why traditional treatments focused on the discs will not be successful in the long-term.

The use of conventional modalities for chronic neck pain remains debatable, primarily because most treatments have had limited success. We conducted a review of the literature published up to December 2013 on the diagnostic and treatment modalities of disorders related to chronic neck pain and concluded that, despite providing temporary relief of symptoms, these treatments do not address the specific problems of healing and are not likely to offer long-term cures.

The objectives of this study are to provide an overview of chronic neck pain as it relates to cervical instability, to describe the anatomical features of the cervical spine and the impact of capsular ligament laxity, to discuss the disorders causing chronic neck pain and their current treatments, and lastly, to present Prolotherapy as a viable treatment option that heals injured ligaments, restores stability to the spine, and resolves chronic neck pain.

There are a number of treatment modalities for the management of chronic neck pain and cervical instability, including injection therapy, nerve blocks, mobilization, manipulation, alternative medicine, behavioral therapy, fusion, and pharmacologic agents such as NSAIDs and opiates. However, these treatments do not address stabilizing the cervical spine or healing ligament injuries, and thus, do not offer long-term curative options. In fact, cortisone injections are known to inhibit, rather than promote healing.

Research on 21 patients with cervical instability and chronic neck pain

In our research published in the European Journal of Preventive Medicine we presented the following findings:

We concluded that statistically significant reductions in pain and functionality, indicating the safety and viability of Prolotherapy for cervical spine instability.(6)
