Both tests should evaluate the movements of the occipitoatlantoid and atlantoaxial joints. Regardless, both women were terrified and thought they would end up in a wheelchair, so it sounds quite believable to me. These problems are much more constant than AAI CCI, which are, for the most part, positional problems. English. Epub 2019 Jun 21. Acta Otolaryngol. 2019 Oct;130:129-132. doi: 10.1016/j.wneu.2019.06.100. 2011, Dashti et al. The atlantoaxial subluxation may exist in patients neutral position (without neck movement) or may occur in relation to neck rotation movements (when the patient moves the neck to the right and left). Unfortunately, she was not compliant to the treatment that I prescribed (TOS, TOS CVH) other than the treatment for AAI, which she was convinced that was her problem. How is possible for them to have results when there is no symptomatic AAI/CCI? Musa A, Farhan SA, Lee YP, Uribe B, Kiester PD. Otolaryngology Case Reports Volume 16, September 2020, 100201, Larsen K, Galluccio FC, Chand SK. The BDI indicates vertical-, and the BAI horizontal structural integrity. He also found that severe misalignment of these joints were often associated with Chiari malformation, basilar invagination, and various other pathologies. (I will post the before- and after images when I return to Colombia in August, as they are on a separated hard drive). I, personally, although I created my own manipulation protocol for this problem ALMOST NEVER use it. Stay put for 30-60 seconds, look for worsening of symptoms while in the test. In BI, the compression tends to be constant. The atlantoaxial complex refers to the first two bones of the neck (C1, the atlas, and C2, the axis) as well as the associated collection of J Korean Soc Magn Reson Med. Clunking and popping that occurs in the upper neck can be scary, but is usually just a sign of facetal rigidity with reduction, meaning that they get stuck and then pop back into place. All patients were treated with atlantoaxial plate and screw fixation using techniques described in 1994 and 2004. And, fair enough, I do not expect blind trust nor compliance. With the increasing dependence on smartphones, computers, and other devices in our modern Neurol India. Moreover, genuine cases of brainstem compression causes paralysis and other upper motor neuron signs, and will present with syringobulbia or compressive bulbopathy. In late stages, even the CTV will show severe compression, and at this stage, surgery may be the best option for resolution if there is clinical correlation. If someone has an ADI of 4.5mm, can this be treated via physical therapy, or is it too much instability? In some circumstances, gradual degenerative basilar invagination can also occur due to gradual and progressive degenerative horizontal misalignment of the atlantoaxial joints (Goel 2014), due to certain diseases such as rheumatoid arthritis, but it is usually caused by head and neck trauma. Symptoms of VBI develop rapidly in patients with legitimate and adequate degrees of vertebral artery compression when placed in the triggering position. A patient with positional brainstem compression due to TAL rupture, for example, will develop neurological (ie. Would this mean that upper cervical chiropractors (orthogonal, blair technique, gonstead, etc.) 3.

Dr. Vicen Gilete, MD, Neurosurgeon & Spine Surgeon. What Is Atlanto-Axial Instability (AAI)? A caveat here may be if the the translational value is very high, as this would be a reasonable indication of foreseeable joint damage, but there is no consensus in the literature with regards to how much that is. Clearly, the expenses involved, including the health risks, may be well worth it if the diagnosis is correct and the patient has legitimate CCI or AAI with strong clinical and radiological evidence. Surgical reduction and fixation would be the only appropriate treatment. This is a major component in the workup for TOS CVH). Last Update [site_last_modified date_format=Y-m-d H:i:s]. Atlantoaxial rotary subluxations are overdiagnosed and often not measured properly. It will rarely cause frank luxation, however where the facets dislocate and lock laterally. In previous years, doctors thought all people with Down syndrome should have regular X-rays to check for AAI. The most commonly used measures in the radiological evaluation of craniocervical instability and atlantoaxial instability are CXA, Grabb, BDI, BAI, ADI. DRAMMEN, NORWAY, Home In the Axis, pedicle screws are usually the first choice although, depending on the patients anatomy, placement of isthmic screws may be considered. For example, if the brainstem is compressed due to a ruptured transverse atantal ligament or due to basilar invagination, a brutally high Grabb-oakes measurement would be expected, and would be a nice extra detail in the report along with the actual information that there is indeed anterior-posterior compression of the brainstem. If the latter, could be JOS obstruction, or could be placebo. Get the latest news on COVID-19, the vaccine and care at Mass General. World Neurosurg. This is important to understand, because maximal rotation will induce, and neutral position will stop the symptoms in patients with legitimate vascular conflict in AAI. Evaluation of the Cause of Internal Jugular Vein Obstruction on Head and Neck Contrast Enhanced 3D MR Angiography Using Contrast Enhanced Computed Tomography. In the cases where it is not possible to obtain autologous bone graft, heterologous graft (artificial bone) may also be used. In severe (very bad) cases, your son/daughter might need neck surgery. 2019 Feb 22;13(1):79-83. doi: 10.14444/6010. 15 Piscataqua DriveNewington (Portsmouth), NH, 03801 603-431-3600, 8 Maple Street, Suite 2 Meredith, NH 03253 603-279-1117, 2023 All rights reserved | Sitemap | Legal | Law Firm Essentials by PaperStreet Web Design, Caudal Cervical Spondylomyelopathy (Wobblers). Why do they have results tho when they correct the atlas/axis? Adapted from Problems with the upper spine in children and adults with Down syndrome (DS) by E. Margolis, B. Henry, B. Sandella and M. Stephens. Then the patient can make an informed decision about whether or not they want to invest in experimental therapy. You mention to test for craniovascular pathologies, we should get a Doppler examination of the carotid and cerebral arteries done, and a CT angiogram done. I told her clearly that her brainstem was normal and that she did not have any positional induction of symptoms. This The brainstem must be compressed from the front and the back, not merely deflected from the front. Surgical management is recommended for those with severe signs and for those who have tried and failed medical management. Both patients had severe symptoms regardless of lying down, wearing a neck brace, etc., and did not get worse nor better when turning or moving their necks. Magnetic resonance imaging assessment of the alar ligaments in whiplash injuries: a case-control study. KL TRENING & REHAB Atlantoaxial fixation: overview of all techniques. Remember that the main dangers of atlantoaxial hypermobility are 1. facetal luxation, and 2., risk for rotational injury to the vertebral artery. If your child has symptoms of AAI, the doctor will suggest an X-ray. Atlantoaxial instability (AAI) is the term for increased motion at the joint between the 1st and 2nd cervical vertebrae (the atlas and the axis). If combined with Chiari malformation, compression of the cerebellar tonsils can cooccur and will occur with lower measurements than normally needed to cause brainstem compression alone, due to filling of the space behind it (the descended cerebellum). J Neurol Surg B. DOI: 10.1055/s-0039-1677706, Perez MA, Bialer OY, Bruce BB, Newman NJ, Biousse V. Primary Spontaneous Cerebrospinal Fluid Leaks andIdiopathic Intracranial Hypertension. Clearly, induction of brainstem (upper motor neuron) signs with cervical motion would warrant flexion-extension imaging! Information about the identification of CVJ fractures will not be applicable for patients with chronic workups and lacking imaging findings over a long period of time. Does thoracic outlet syndrome cause cerebrovascular hyperperfusion? 2014 Apr;5(2):59-64. doi: 10.4103/0974-8237.139199. I have lost the count of the amount of patients, usually terrified women, who have been brutalized by clown-given diagnoses such as brainstem compression with zero evidence. These cookies do not store any personal information. This increased mobility causes headache and cervical pain as well as signs of compression of adjacent neural elements that form cervicomedullary syndrome. Radiologic spectrum of craniocervical distraction injuries. It baffles me when I see patients with 130 degree CXA and some additional signs of mild/moderate laxities being butchered with C0-T1 surgery despite there being NO instability in the cervical spine and only mild findings in the upper neck that are not causing any neurovascular conflicts nor facetal lockups (eg., Cock Robin syndrome). More information about surgical treatment. 2012). A CTV is preferable, but a general neck CT will also do if you have sensitive kidneys and would like to avoid contrast infusion. Many of these patients who have been misdiagnosed with AAI or CCI may feel neck wobbliness, heaviheaded, neck weakness, and clicking or clunking in the neck upon movement, often along with upper neck pain. None of these tests would be able to reproduce her symptoms if they were stemming from AAI or CCI. Explore fellowships, residencies, internships and other educational opportunities. The natural anatomic C1-C2 movement is basically rotation and approximately implies 50% of necks total rotation movement. Accessory nerve compression can cause weakness of the trapezius and sternocleidomastoid muscles, but can also cause cervical dystonia. Atlas screws are generally placed in the lateral masses. If the X-ray results are abnormal (different than usual), the doctor will order another imaging test, like a computed tomography (CT) scan or magnetic resonance imaging (MRI) test. PMID: 24475346; PMCID: PMC3899735. The CXA was 138 degrees and the Grabb-Oakes measurement was 8,3mm. Research has shown that normal limits are 3 and 10mm, with an absolutely maximum of 12mm (Ross & Moore 2015). It is possible to do it with extension and rotation, etc., but it is usually not necessary. All conventional things like heart and lung problems, MS, cancer, infections etc. Ultimately, the reader must discern for themselves. Diagnosis is often based on survey radiographs, alth Atlantoaxial Instability We moved on to perform the Valsalva maneuver (a pressure test), the Queckenstedts test (manual venous compression test), and the cervical retraction test (TOS CVH), in which the first and third tests were positive, reproducing severe head pressure, dizziness, presyncope and profound fatigue. This conformation may be associated with thickening of the interarcuate ligament (atlantoaxial band), which has been interpreted as an indicator for instability in the atlantoaxial joint [79]. The atlantoaxial complex refers to the first two bones of the neck (C1,the atlas, and C2,the axis) as well as the associated collection of ligaments that connect the bones together and the blood vessels that travel through them to the brain. But, if a specialist points something out that is not conventionally considered, he should either 1. make sure to emphasize the notion that it is a subtle finding with unsure actual clinical applicability or 2. make sure to prove his points through objective findings. Common arguments for treatment may be claims that, although the MRI and even upright MRIs are normal, their own DMX scan is positive, or that the MRI, which was deemed normal by the local hospital, in reality shows signs of ruptured ligaments and that this fits with the patients symptoms. Moderator. However, I also told her that she may end up having fixation surgery in the future to prevent foreseeable compressive damage to the brainstem. Advanced Surgical Neuro-oncology Fellowship, Complex and Minimally Invasive Spine Deformity Fellowship, Endovascular Surgical Neuroradiology Fellowship, Neurosurgical Spine Innovation Fellowship, Neurosurgical Peripheral Nerve and Spine Fellowship. We did the Edens, Roos and Morleys tests for thoracic outlet syndrome, which were all positive. Just like the CXA, this measurement is supposed to aid with objective measurements rather than just eyeballing the images, and writing down your impressions. PMID: 19769514. In people with Down syndrome, the ligaments (connections between muscles) are lax or floppy. November 19, 2014 at 8:19 pm. We also use third-party cookies that help us analyze and understand how you use this website. Testimonials Compare the two to obtain the degree of rotation. Necessary cookies are absolutely essential for the website to function properly. Atlanto-axial rotatory fixation. One is especially predisposed to this problem if the affected vertebral artery is highly dominant (much higher caliber than its contralateral counterpart) or if the contralateral artery is extremely hypoplastic, or, finally, the contralateral artery terminates as the posterior inferior cerebellar artery rather than at the basilar artery (Josy & Daily, 2015). This, seriously augmented by poor hinge neck postures (Larsen 2018). The functional result of If the patients neck often completely locks up due to facetal luxations, then atlantoaxial fixation may certainly be a viable option for treatment, especially if conservative stabiization fails (capsular and alar ligamentous prolotherapy, postural corrections, strengthening of the suboccipital, longus capitis and levator scapulae muscles). Posture is done for the rest of your life. Facetal locking with rigid torticollis (Cock Robin syndrome) or similar, in cases where there is no neurological compromise, is less dangerous. Must be carefully evaluated and correlated with the patients symptoms). doi: 10.1227/NEU.0b013e3182333859. When Atlantoaxial instability occurs along with craniocervical instability, also known as occipitocervical instability (ie instability present also between skull and first cervical vertebra or Atlas), then fusion should consist of adding a fixation to the cranial bone through occipital or condylar screws which would give us as a whole C0 -C1-C2 posterior fusion. Although there were no current grounds for surgery? AA instability is typically diagnosed by performing radiographs (x-rays) of the neck. 1927;11(1):155157. Most cases of mild to moderate unilateral compression, sometimes even intermittent occlusion, is asymptomatic due to contribution from the contralateral VA (Faris et al. Congenital, inflammatory, traumatic, We can consider that there is atlantoaxial instability or atlantoaxial subluxation (AA subluxation) in cases where there is principally incompetence of the ligamentous elements of the atlantoaxial (C1-C2) joint, which allow a significant increase in the mobility of this area thus considered pathological mobility. My experience has been that these approaches do not work, and certainly do not cause long term results. It is not a substitute for medical advice and should not be used to treatment of any medical conditions. It mainly consists of the posterior fusion of the affected vertebrae, in this case, the atlas (C1) and the axis (C2). A lot of things that cause temporary results are just placebo. Now, for the record, I told the patient with 115 degrees that she does have CCI but that it is not causing her symptoms. Generally, however, in ligamentous laxity, some bowing and lateral hypermobility (evident by lateral flexion overhangs) will almost definitely not result in frank luxations down the line nor do they tend to elicit symptoms from the actual atlantoaxial facet joints. Styloidectomy and Venous Stenting for Treatment of Styloid-Induced Internal Jugular Vein Stenosis: A Case Report and Literature Review. Therefore, when there is evidence of equivocal findings such as signal changes in ligamentous structures without expected adherent findings such as gross hypermobility compatible with the injury at hand, this can generally not account as someting sinister. 2014 Aug;4(3):197-210. Rather, just like with the CXA, it is an indication of the present spinal health status and perhaps also an indicator as to non-surgical prognosis as well as an indicator of likely outcome if nothing is done. Styloidogenic jugular venous compression syndrome: diagnosis and treatment: case report. Atlantoaxial instability | Cervical Fusion or Prolotherapy PRP Stem Cell treatment options Surgical treatments for Cervical Instability Disc, disc, disc may be wrong, wrong, wrong In At Dr Gilete we are experts in Ehlers Danlos surgery, craniocervical instability EDS,neuro and spine disorders related to EDS and whiplash. A critical view on the overdiagnosis of AAI/CCI. 2021 Jun;44(3):1553-1568. doi: 10.1007/s10143-020-01345-9. This pain tends to get worse with stress and with high heart rates, and are often also worse in the morning after lying down. Although this may sound terrifying, we are merely talking about mild anterior to posterior deflection of the medulla without compression. I have also seen cases of seventh nerve dystonic mimicks several times in JOS, where platysmal dystonia or even oropharyngeal dystonia (hypoglossal nerve) has been identified, worsened with neck tucking (which increases the compression) and resolved with specific strategies for widening the atlanto-styloidal interval (see my atlas article as linked earlier) or Larsen 2018 in the reference list). Because of its role in movement, it is, unfortunately, commonly injured. Josy GF, Daily AT. More information about surgical treatment. An X-ray is low-cost and low-risk, but it does not always tell whether a person has AAI or not. PMID: 18708935. Then, if there are not even sufficient findings for surgery, how can one possibly give such a fatal prognosis? Pain medications and anti-inflammatories are typically also prescribed. Save my name, email, and website in this browser for the next time I comment. Upright MRI has very low quality and because of this, there is a lot of guesswork involved in its interpretation. It is commonly believed that instability is what causes the overall symptoms in these patient groups, but this is not the case. The patient will hinge back at their neck while simultaneously flexing the cranium. She was also said to have ventral brainstem compression, which particularly scared her due to her difficulties with respiration. Atlantoaxial rotatory subluxation Contact Dr. Gilete Our commitment to reliable health and medical information on the internet This site complies with the HONcode standard for trustworthy DOI: 10.3171/2015.1.FOCUS14791. There is a growing trend, however, within the (or, at least, certain) alternative medical communities, where patients with normal or virtually normal imaging, and with the absence of clinical triggers that would suggest atlantoaxial or craniocervical instability, still end up diagnosed with these relatively sinister diagnoses. It is imperative to understand that patients with dagerous craniovertebral junction injuries, although one may sometimes require a dynamic CT or x-ray to identify them, will have clear imaging findings combined with clear clinical triggers in the utmost majority of incidences. I am not saying that this applies to every DMX center nor that DMX in and by itself is never useful, but due to the overwhelming lack of competence that tends to come with these studies, I dont recommend them unless unless you have obviously abnormal imaging otherwise and want to look for occult fractures or similar sinister and stubbornly identified problem. 1963;13(5):386396. For example, although the medical literature (almost exclusively biased reports written by people considered experts on the topics (I am also biased on the topic; all experts are) may suggest a clivo-axial angle lower than 150 degrees as abnormal, this is still a measurement used to associate concrete craniocervical angles with medullary compression. Medical management entails strict cage rest and placing a neck brace (from in front of the ears to the mid-chest) to prevent the vertebrae of the neck from moving and causing more damage to the spinal cord. If this X-ray is repeated, the AAI might go away. If a gliding is causing it (it is usually a glide or, a glide combined with mild rotation), no manipulation can fix it. Conveniently, she was sent out to a colleague for very expensive nonsense therapy (again, regardless of lacking serious findings that would require surgery) and sent tens of thousands of euros on stemcell and prolotherapy procedures in a desperate attempt to avoid the inevitable wheelchair. Search for condition information or for a specific treatment program. Type one involves sole rotary luxation of the facet joints, usually along with damage to either the alar ligaments and capsular ligaments. Because it doesnt work most of the time, and doesnt cause any lasting results. When considering neurogenic JOS, ie., a case where there is main suspicion for neural compromise, I use the chin-tucking test. Medullopathy (signal changes, cord damage) will not occur by mere deflection, which is also evident by the blatant lack of upper motor neuron findings in these alleged brainstem compression patients. To schedule an appointment, call one of the offices, or book an appointment online. I prefer to compare mid-jugular to the highest pressure found, usually in the torcula or SSS. Second, because it is such a controversial topic that lacks medical consensus, poor understanding of the actual mechanism of pathology leads to misunderstandings. This would depend on whether or not the compression of the brainstem is constant, which again would depend on several factors. Mild to moderate cases tend to respond well to appropriate conservative therapy (not general therapy), cf., once again, my atlas joint article from 2017 linked several times earlier. 1963). Patients with craniovenous outlet obstruction due to JOS may induce their symptoms with a Queckenstedts test, that is in essence a manual compression test of the internal jugular veins. Org. J Craniovertebr Junction Spine. The doctor will tell you which sports and activities are safe for your son/daughter. I told her that, although I dont think theres any evidence to suggests that the AAI is causing your symptoms, we should still treat it to prevent the risk of future frank luxations of the joints. Often, by radiologist alone, based on sparsome imaging findings (eg., alar ligament T2 FLAIR hyperintensity or mild to moderate lateral facetal overhangs) and a lacking compatible clinical workup. Call us: 212.774.2837 This article will take a critical look at these diagnoses and elaborate upon the factual structural risks that are seen in atlantoaxial- and craniocervical instabilities, as well as their expected realistic symptoms and triggers. The joint between the upper spine and base of the skull is called the atlanto-axial joint. This can be a blessing if one proceeds to be properly diagnosed based on objective criteria, but often extremely expensive and also dangerous, if not. PMID: 33064218. 914 390 028 Goel A. Facetal alignment: Basis of an alternative Goels classification of basilar invagination. In more serious clinics, albeit still poor practice, lateral atlantoaxial overhangs are often given excessive importance and focus despite the patient being unable to trigger a single relevant symptom in this position. But this measurement in and by itself, when it is 9 or 10 or even higher, but there is no brainstem compression not even in flexion-extension imaging this cannot be interpreted as a surgical indicator. Copyright Dr Gilete Neurosurgery & Spine Surgery. I believe that most of these practitioners mean well. Now, it is true that specialty diagnoses can be missed by local generalists. Donald Corenman, MD, DC. the section on bow hunters syndrome. Whats interesting, regardless, is that one year after we had the first consultation she underwent another uMRI (due to lack of improvement of symptoms), which showed completely resolution of the atlantoaxial subluxations, which were now overlapping at about 30%; 300% improvement (remember: >20% is normal). After hospital discharge, doctors usually control patients at least once a week after discharge on an outpatient basis, to make sure everything is correct before flying back home, thus we recommend to stay in Barcelona after discharge for 10-15 days. I diagnosed her with mild (benign) atlantoaxial instability and TOS CVH. 2014 Feb;11(1):75-82. ncbi.nlm.nih.gov/pubmed/24321024, Higgins JN et al. Powers ratio will be abnormal in cases of both BI and craniocervical dissociation (Ross & Moore, 2015). Epub 2014 May 22. I consulted with her and reviewed her imaging: The quality of the images, first and foremost, was very low. No improvement! The other side of the AAI/CCI coin is the risk for facetal luxation; a less sinister-, but still a problem that warrants surgical treatment. In most cases it is convenient to put bone graft, usually autologous, taken from the iliac crest or the patients own rib. It is, as we say, in tangent with the dens and tectoral ventrally alone. Anaesth pain intensive care 2020;24(1)69-86. (Fixed rotatory subluxation of the atlanto-axial joint). For example, I have seen patients with 45 degrees of rotation (which is higher than normal) between the C1-2 that had completely normal overlap due to large facets, and I have seen patients with 30 degrees of rotation (which is usually completely normal) with poor overlap and AAI, due to small facetal surfaces. Another scenario could be that the patient has been diagnosed with atlantoaxial rotary subluxations, as little facetal overlap, lets say, 15%, is seen upon bidirectional rotation. For the sake of relevance, this article will mainly address ligamentous and muscular injuries, as these topics, especially when mild, are much more controversial than incidences of CVJ fracture. If unavailable, a CT angiogram can be used, but is less sensitive. TOS increases perfusion rates to the brain, to which the brain is very sensitive and may dysfunction depending on how high the pressures are (Larsen et al 2020), often resulting in severe fatigue, dizziness, headaches and especially occipital headaches/pain (these are hypertensive headaches, not an atlas problem). 1-Craniocervical instability, levels C0-C1 (Occipital-atlas). 2015. It is important to understand that the size of the facets is what determines what degree of rotation would be excessive. And if yes, do they completely normalize when resuming neutral position? The utmost majority of these patients have have normal supine imaging, and many of them also normal or nearly normal upright imaging. 2011 Apr;15(1):41-47. ADI laxity is mainly caused by head and neck trauma, so as long as you avoid future collisions, it will probably not deteriorate. Spinnato P, Zarantonello P, Guerri S, Barakat M, Carpenzano M, Vara G, Bartoloni A, Gasbarrini A, Molinari M, Tedesco G. Atlantoaxial rotatory subluxation/fixation and Grisels syndrome in children: clinical and radiological prognostic factors. Rather, it must be compressed by the dens ventrally, and flaval ligament and lamina posteriorly. In dogs with atlantoaxial subluxation, instability of the atlantoaxial joint results from a loss of ligamentous support of the axis, often with concurrent aplasia, hypoplasia or dysplasia of the dens. This, usually due to trauma, but can also occur gradually due to certain autoimmune disorders such as rheumatoid arthritis, gross congenital hypermobility (such as Ehler Danlos syndrome or Marfan syndrome), or certain congenital syndromes such as Downs syndrome (Yang et al. 2014 Aug;4(3):197-210. doi: 10.1055/s-0034-1376371. The surgical treatment for Atlantoaxial instability, when it manifests alone without occipitocervical instability, it mainly consists of a You can read more about these problems in my Myalgic encepalitis (link) and intracranial hypertension (linked earlier) articles as well as my 2018 and 2020 papers (Larsen 2018, Larsen et al 2020) in the reference lists if you think this may be you. 14 Postoperative care advices following cervical disc herniation surgery, 4 Predictive factors of the results in Cervical Herniated Disc surgery. These cookies do not store any personal information. If there is no medullary compression, not even in a flexion/extension scan, then we cannot say that the patient is of surgical degree, even if it is very low, unless they look so bad that it is reasonable to expect frank compression in the near future! Not sure what you mean here. One or 2 out of every 100 children with Down syndrome have symptoms of AAI, but doctors do not know the exact number yet. Compression of the glossopharyngeal nerve will frequently cause pharyngeal pain (back of the throat pain) whereas vagal compression may lead to dry coughing, lump in the throat feeling, ear itching and various strange things when unilateral, but has been associated with more problematic issues when bilateral such as gastroparesis (Waldock et al.
