2014 Aug;4(3):197-210. doi: 10.1055/s-0034-1376371. 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.

Out of these, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. Epub 2020 Jul 4. 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. The personalized evaluation of each case is always convenient since it is very important that abnormalities of the vertebral artery anatomy are ruled out as well as the possible anatomical differences regarding the layout and dimensions of the vertebral pedicles, lateral masses and other bone elements. Brainstem compression, when symptomatic, will usually cause quadriparesis along with phrenic nerve palsy. 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). This is no longer true. This will be predominantly evident on a flexion/extension scan, where the basion-dens interval (BDI) will be dynamically increased, and greater than 10-12mm (Ross & Moore, 2015; Deliganis et al. In my experience, although I usually disagree with their diagnoses, is that Medserena in London has the absolute best upright imaging quality in the world. The alignment of the atlas itself isnt really the problem; the problem is whether or not a rotation or a horizontal glide is causing encroachment of the jugular outlet. A CTV is preferable, but a general neck CT will also do if you have sensitive kidneys and would like to avoid contrast infusion. Thus, it is important to measure both the percentile overlap as well as the degree of rotation bidirectionally. But opting out of some of these cookies may affect your browsing experience. Tambin conocer las causas, los signos y los sntomas de la IAA. Anaesth pain intensive care 2020;24(1)69-86. Regardless, be it rooted in benevolent or malevolent intention, this does not change the fact that pursuing the diagnosis and especially its related treatment (conservative or surgical strategies) are extremely expensive and potentially dangerous as well. 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. In previous epidemiologic studies, the prevalence of atlantoaxial instability in persons with Down syndrome was found to be between 9% and 31%. A patient with positional brainstem compression due to TAL rupture, for example, will develop neurological (ie. And, she still had the same symptoms! In patients with Ehler Danlos syndrome, instability is present frequently in several segments, generally C0-C1-C2 (from occipital to axis). In addition to that we would start treatment for thoracic outlet syndrome. Surgery is often challenging because of the shape of the C1 and C2 bones, and because the vertebral arteriespass in and around these two bones on the way to the brain. 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 the patient is indeed positionally symptomatic, however, and there is compatible imaging evidence, either atlantoaxial fusion, transverse foraminotomy or certain physical therapies may be warranted depending on how severe the findings and symptoms are. The joint between the upper spine and base of the skull is called the atlanto-axial joint. Atlanto-axial instability (AAI) is a condition that affects the bones in the upper spine or neck under the base of the skull. The joint between the upper spine and base of the skull is called the atlanto-axial joint. In people with Down syndrome, the ligaments (connections between muscles) are lax or floppy. We'll assume you're ok with this, but you can opt-out if you wish. These cookies will be stored in your browser only with your consent. My experience is that most of these patients suffer from craniovascular pathologies, not CCI and AAI. 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. None of these tests would be able to reproduce her symptoms if they were stemming from AAI or CCI. I completely disagree with this and, once again, refer to common sense thinking that if the joint positions are within normal limits then there is very little risk, if any, of any damage to the spinal cord or segmental arteries. Wake up and walking begins on the second day after surgery. If you have an atlanto-dens interval (ADI) of 5mm or greater, you have instability by definition. Global Spine J. For treatment of the facetal dysfunction I recommend postural correction for the head neck and shoulder blades, along with exercises for the trapezius, levator scapulae, suboccipital and deep neck flexor muscles. If the patient turns their head and passes out, and a catheter scan demonstrates dominant vertebral arterial compression, then certainly this is a case of AAI and atlantoaxial fixation may be a viable option, at least if the transverse foraminae are normal. If someone has an ADI of 4.5mm, can this be treated via physical therapy, or is it too much instability? Dashti SR, Nakaji P, Hu YC, Frei DF, Abla AA, Yao T, et al. Learn about career opportunities, search for positions and apply for a job. The renowned scholar and neurosurgeon professor Atul Goel was the first person, to the best of my knowledge, to acknowledge and document the notion of horizontal misalignment of the craniocervical facet joints and that this would often be present despite a completely normal-looking mid-sagittal slice (where most craniovertebral junction measurements are done). If the latter, could be JOS obstruction, or could be placebo. That said, yes, it is my opinion that the treatment is nonsense. Then, if there are not even sufficient findings for surgery, how can one possibly give such a fatal prognosis? 404-256-2633. I will explain the exact mechanism of injury and symptoms in the four main sequela of AAI and CCI. 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! Ann Rheum Dis. Presuming the central venous pressure being normal, then I am not so interested in the pre and post-stenotic gradients as they tend to be unreliable. Both tests should evaluate the movements of the occipitoatlantoid and atlantoaxial joints. That is why they are much less affected by actual neck position than legitimate CCI AAI patients are, and certainly do not become symptom free in neutral positions. The patient should demonstrate some brainstem symptoms, and may develop quadriparesis if the compression is sufficiently hard and constant. The atlantoaxial instability may also have an acute traumatic origin, which may sometimes require urgent treatment, though in some cases it triggers development of the craniocervical or atlantoaxial instability. Craniocervical Instability (CCI), also known as the Syndrome of Occipitoatlantialaxial Hypermobility. Patient resources for the Down Syndrome Program. Explore fellowships, residencies, internships and other educational opportunities. Apr 2, 2022 Any experience of Atlantoaxial instability? PMID: 32623537; PMCID: PMC8121728. had been excluded by her primary care physicians and local hospital. Maybe they temporary fix some compression? Although there were no current grounds for surgery? The BDI was 6mm and the BAI was 8mm, which are all farily normal. She was never evaluated for clinical correlation for these alleged findings, ie., no one evaluated if these findings had actual compatibility with her clinical symptoms and, especially, triggers. Something I often see reported as alleged evidence of sinister CCI, is a translational BDI or BAI (the basion-axial interval is the horizontal distance between the tip of the clivus and the posterior wall of the odontoid process. The atlanto-occipital joint allows your head to move up and down, while the atlantoaxial joint lets your head rotate. 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. Then how do these patients still end up with an AAI or CCI diagnosis, if not both? Sometimes, the symptoms may trigger within a few minutes after the test as well, depending on various factors which exceed the scope of this article. However, can we say the same if there is major guesswork involved in the rendering of the diagnosis? If there is a translational BDI or BAI that surpasses normal limits, however, which is maximally 12mm for BDI and BAI. 1927;11(1):155157. 1. Her symptoms, however, did not at all change when changing her neck position and she had never had torticollis. Bow hunters syndrome revisited: 2 new cases and literature review of 124 cases. In the cases where it is not possible to obtain autologous bone graft, heterologous graft (artificial bone) may also be used. In previous years, doctors thought all people with Down syndrome should have regular X-rays to check for AAI. Yang SY, Boniello AJ, Poorman CE, Chang AL, Wang S, Passias PG. Identifying The Signs Of Cervical Instability. Patients with genuine and symptomatic rotational vertebral artery compression will develop symptoms of vertebrobasilar insufficiency when they fully rotate their heads to one or both directions, and may be further worsened if done simultaneous with neck extension (DeKleyn 1927). See my youtube channel for appropriate training. Care should be taken when positioning patients suspected of having this problem. Sometimes flexion-extension and rotational imaging is necessary. 9/2017. 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. It is not a substitute for medical advice and should not be used to treatment of any medical conditions. Finally, beware that many of these uMRI clinics render horrible images that barely show any anatomy, yet somehow still manage to determine various complicated diagnoses from them. However, I also told her that she may end up having fixation surgery in the future to prevent foreseeable compressive damage to the brainstem. This is what I said from the beginning; AAI is not the cause of these symptoms, the exam and triggers do not fit. https://doi.org/10.13104/jksmrm.2011.15.1.41. How is possible for them to have results when there is no symptomatic AAI/CCI? In most cases it is convenient to put bone graft, usually autologous, taken from the iliac crest or the patients own rib. Search for condition information or for a specific treatment program. As mentioned initially in this article, craniocervical instability is mainly associated with jugular outlet obstruction and basilar invagination, whereas atlantoaxial instability can cause posteriorization of the dens and brainstem compression, or rotational dysfunction resulting in either bow hunters syndrome, Cock Robin syndrome or other variants of segmental luxations. Research has shown that normal limits are 3 and 10mm, with an absolutely maximum of 12mm (Ross & Moore 2015). The reason why AAI and CCI are potentially associated with so many symptoms such as headache, dizziness, etc., is due to the potential for neurovascular conflict. Facetal locking with rigid torticollis (Cock Robin syndrome) or similar, in cases where there is no neurological compromise, is less dangerous. The atlantoaxial subluxation can occur isolated or can be found in cases in which there is also craniocervical instability. In these cases, the direct signs and indirect signs of atlantoaxial subluxation must be objectified. Symptoms of brainstem compression are respiratory crisis and quadriplegia, but can also manifest more diffusely. This is reasonable. The most commonly used measures in the radiological evaluation of craniocervical instability and atlantoaxial instability are CXA, Grabb, BDI, BAI, ADI. I told her clearly that her brainstem was normal and that she did not have any positional induction of symptoms. 10 things you should know about Cervical Disc Replacement. Copyright 2007-2023. 2014 Feb;11(1):75-82. ncbi.nlm.nih.gov/pubmed/24321024, Higgins JN et al. 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. Moreover, I have heard numerous similar stories from other patients. The same principles would apply for AAI and CCI: There must be clear imaging findings, and I am not talking about a simple measurement being off, but real pathology proven to be associated with the given diagnosis. One patient was told by a famous alternative european neurosurgeon that she has CCI and AAI, and although there is no evidence for current surgery, she would probably be in a wheelchair within a few years and might even die. Some rare cases have also demonstrated rotary compression of the vertebral artery in the lower neck due to arthritis or disc bulges that fills up the transverse foraminae (Ujifuku et al. Atlanto-axial instability (AAI) is a condition that affects the bones in the upper spine or neck under the base of the skull. If you are very concerned that you have craniocervical and atlantoaxial instability, then I recommend getting workups for both these but also relevant differential diagnoses. Neuronavigation assistance guides us all through the surgery, thus it diminishes (though it does not eliminate) the risks while placing the screws for the fusion. PMID: 33064218. 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). A positive test would be interpreted by unbearable head pressure, lightheadedness, worsening of headache, etc., within about 20-30 seconds. DMX I dont recommend getting a DMX. Dr. Gilete in Spain, although I often disagree with his diagnoses, tends to order beautiful dynamic CT scans and also good craniovascular scans. Imaging will prove brainstem compression on [flexion/extension] MRI, and an increased atlantodental interval on flexion/extension CT or x-ray. It is advisable to obtain just a lateral view first. Surgery to address problems in this area can be risky. Another patient was told by a well-known pain physician in the US that she had brainstem compression and required several expensive prolotherapy procedures. Both measurements tend to worsen with neck extension. 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. Dr. Christopher Williams | 07/09/2020. Epub 2014 May 22. Education This would apply for patients with obvious hypermobility but who do not have clinical triggers compatible with CCI or AAI (induction of symptoms in flexion, extension or rotation, and complete normalization when in neutral). This website uses cookies to improve your experience while you navigate through the website. For occipial neuralgia, an ultrasound guided nerve block will cure these symptoms for three hours and thus confirm the diagnosis. (Fixed rotatory subluxation of the atlanto-axial joint). A 3D rendered CT scan should easily demonstrate the luxation in cases where the sagittal slices appear normal or close to normal, whereas cases of dens migration will also appear obviously abnormal in the sagittal planes of imaging. Basil R. Besh, M.D. Look for upright compression of the IJVs), Dynamic CT also works well, but has much more radiation. Acta Otolaryngol. 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. Larger breeds can also be affected, and any dog or cat is at risk of a very similar acquired injury if they sustain trauma, such as being hit by a car. Atlantoaxial instability (AAI) is a potential complication of all forms of EDS. Another problem with regards to rotation, is that the measurements are often done wrong. Now, the I was told is clearly second-hand information, and I cannot guarantee its accuracy. What is atlanto-axial instability? The problem has received various names such as mere jugular vein compression, venous eagles syndrome, but I have called it jugular outlet syndrome (JOS), as it is a problem that not only affects the craniovenous outflow, but also several cranial nerves, and can be culpable in various strange neurological disorders (Read my atlas article (link) I also have an upcoming paper on this topic that I hope to release this or next year). Evaluation of the Cause of Internal Jugular Vein Obstruction on Head and Neck Contrast Enhanced 3D MR Angiography Using Contrast Enhanced Computed Tomography. For TOS CVH the patient will generally feel better when stress is reduced along with taking beta blockers (confer with your doctor). Atlantoaxial instability is a relatively frequent finding in individuals with Down syndrome. What Is Atlanto-Axial Instability (AAI)? Due to the instability in the craniocervical junction deformation can occur to the brainstem, upper spinal cord, and cerebellum. Neurology. -Dr. Vicen Gilete, MD, Neurosurgeon & Spine Surgeon. Anaesth Pain & Intensive Care 2018;22(2):238-242. We were referred to a specialist vet (swift in Wetherby) who thinks it is AAI but unless she regains use of her legs they cannot operate In early stages, the jugular outlets passage is only obstructed posturally, and will appear normal on supine MRI, but abnormal on upright MRI. In severe cases, I recommend postural corrections (appropriate, not generic) along with styloidectomy and transversectomy. But if there is lots of space for the medulla, such invasive surgery simply is not warranted. and craniovenous outflow obstruction) will frequently cause severe fatigue, migraine, headache, dizziness, tinnitus, pain in the upper neck/back of the head (this is hypertensive migraine, not atlas pain Larsen et al 2020), POTS, memory loss, cognitive decline or fluctuating cognitive ability, syncopal event, seizures, and even, sometimes, hemi or paraparesis and other stroke-like symptoms. This can also damage the brainstem and produce symptoms similar to what is described above. Neurol India. Traumatic Atlantoaxial Lateral Subluxation With Chronic Type II Odontoid Fracture: A Case Report. Symptoms of VBI develop rapidly in patients with legitimate and adequate degrees of vertebral artery compression when placed in the triggering position. Atlantoaxial instability is a congenital neurologic condition predominantly affecting toy breed dogs. 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. In addition to reproducible clinical triggers (positions), the patient should preferably undergo a dynamic catheter angiography of the neck. What I prefer to do is to first draw lines that show the actual rotational alignment of the C2 and C1 when looking left and right. To compress the brainstem it must be compressed from both sides, both infront and behind. 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. 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. Not sure what you mean here. I consulted with her and reviewed her imaging: The quality of the images, first and foremost, was very low. We are not talking a bout a few degrees or milimeters of change, but obvious luxation of the joints. Last Update [site_last_modified date_format=Y-m-d H:i:s]. Some have proposed 2mm of translational difference, but this is completely unreliable in my opinion and exprience. He also found that severe misalignment of these joints were often associated with Chiari malformation, basilar invagination, and various other pathologies. Type three involves anterior subluxation of the entire atlas due to combined full rupture of the TAL and partial rupture of the capsules and other structures. At Dr Gilete we are experts in Ehlers Danlos surgery, craniocervical instability EDS,neuro and spine disorders related to EDS and whiplash. Just like the CXA, this measurement is supposed to aid with objective measurements rather than just eyeballing the images, and writing down your impressions. Atlanto-axial rotatory fixation. At the very least, if the clinician has clinical suspicion but no concrete holdingpoints for their diagnosis, they must be honest about this. 2008 Aug 15;33(18):2012-6. doi: 10.1097/BRS.0b013e31817bb0bd. TOS is often considered a mere upper limb nerve pathology, but this is not the case. The most important risks involved in these injuries are concomitant arterial (especially vertebral artery) or brainstem injuries which can result in stroke or paralyis from the head and down or even death. But this is rarely the case in my experience. #11760. It is not due to mild overall instability that does not cause neurovascular conflicts. I dont recommend MRA. Copyright Dr Gilete Neurosurgery & Spine Surgery. Call us: 212.774.2837 In such a case, UMN symptoms and signs would be expected as well. English +34 93 220 28 09 Espaol +34 93 198 34 24 Patients with normal structural alignment and more or less normal or completely normal radiological imaging, without clinical correlation, end up diagnosed with CCI or AAI due to a slightly low (non-sinister) CXA, say 135 degrees, and some signal changes in the alar ligaments on T2 FLAIR imaging or slight increase in the atlantodental interval (ADI) despite normal thickness of the transverse atlantal ligament (TAL). 2008). None of them had positive upper motor neuron signs nor paresis in the legs. Radiographics 2000;20:S237-50. PMID: 25083363; PMCID: PMC4111952. 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. English. Patients with horizontal instability of the craniovertebral junction but without rotary subluxation may not necessarily demonstrate the same level of rigidity, but may show induction or resolution of symptoms as they venture into flexion vs. extension. De Kleyn A, Nieuwenhuyse P. Schwindelanfalle und Nystagmus bei einer bestimmten Stellung des Kopfes. -Mummaneni PV, Haid RW. Atlantoaxial instability and craniocervical instability are spinal manifestations directly due to ligament laxity. The patient had headache, dizziness, fatigue, pain in the arms and chest and often felt difficulty breathing. She worsened with arm-loading, and often worsened when lying down, especially the breathing dysfunction tended to exacerbate and become more pronouned at night-time, resulting in anxiety and insomnia. 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. Musa A, Farhan SA, Lee YP, Uribe B, Kiester PD. For patients with post-traumatic ligamentous injuries where measurements are still within normal limits, obvious segmental effusion should be seen despite otherwise normal anatomical positioning. I recommend doing this with a neuro-ophthalmologist, not a general ophthalmologist or opticician, as the findings are often missed. This is easily seen on imaging, especially on CT, as the alignment of the joint will be unequivocally abnormal to the extent that would not be achievable without tremendous ligamentous injury. ARTICLE IN PROGRESS The piece is virtually finished, but I am missing some imaging that I dont have access to here while I am on vacation in Norway. Second, because it is such a controversial topic that lacks medical consensus, poor understanding of the actual mechanism of pathology leads to misunderstandings. Merely feeling worse when standing up, even if indeed feeling awful, is not a strong indicator of AAI CCI As mentioned above, it is the influence of cervical positioning. When rotated to the right, making sure that the axial alignment of the imaging program is aligned with the spinal column longitudinally, compare the anterior aspect of the right facet vs. the facet of the C2, and the posterior aspect of the left facet vs. the facet of the C2 and calculate the actual percentile of overlap. Safe Care CommitmentGet the latest news on COVID-19, the vaccine and care at Mass General.Learn more. We can still treat it preventatively, but it wont resolve the symptoms. There can be, and are indeed many more potential explanations for these symptoms than just AAI and CCI. 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. 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. AAI is less common in adults with Down syndrome. I have seen several patients misdiagnosed and become almost paralyzed by anxiety due to an increased Grabb-Oakes measurement where the dens is just barely in tangent with the brainstem, despite zero evidence of actual compression nor signal changes in the brainstem and with normal neurological examinations without any upper motor lesion signs! Burry et al (1978) documented a rare case of lateral luxation in a patient with rheumatoid arthritis, in which the supporting facet had eroded away. The same applies for conservative strategies to reduce internal jugular vein compression. Org. Must be carefully evaluated and correlated with the patients symptoms). Four broad categories of atlantoaxial problems were observed-atlantoaxial rotatory subluxation in six patients, anterior-posterior atlantoaxial instability caused by ligamentous injury or congenital ligamentous laxity (10 patients), atlantoaxial fracture with or without dislocation (five patients), and atlantooccipital dislocation (two patients). Clinical signs of such an injury include neck pain, weakness in all limbs, and potentially paralysis from the neck down and death. The success rate of this surgery is 80% or greater; however, there are many potential complications and a mortality rate of 5-10%. 1978 Dec;37(6):525-8. doi: 10.1136/ard.37.6.525.
