Atlantoaxial instability is a relatively frequent finding in individuals with Down syndrome. This pain tends to get worse with stress and with high heart rates, and are often also worse in the morning after lying down. Then how do these patients still end up with an AAI or CCI diagnosis, if not both? If there are no symptoms, then what reuslts are you talking about? 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. 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). Both positional (ie., upright. 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. However, can we say the same if there is major guesswork involved in the rendering of the diagnosis? Furthermore, a claim of brainstem stretching and kinking with resultant medullary microdamage that somehow not responds negatively to being stretched in real-time, and also lacking upper motor neuron signs, is not a very realistic claim. Thus we control the spinal cord and nerves (cranial and cervical) in order to avoid potential damages to these important structures. Upright MRI has very low quality and because of this, there is a lot of guesswork involved in its interpretation. Headache, cerebrospinal fluid leaks, and pseudomeningoceles after resection of vestibular schwannomas: efficacy of venous sinus stenting suggests cranial venous outflow compromise as a unifying pathophysiological mechanism. Post count: 8446. Headaches certainly can develop from instability of C1-2. Otolaryngology Case Reports Volume 16, September 2020, 100201, Larsen K, Galluccio FC, Chand SK. 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. Privacy policy, Do you really have atlantoaxial and craniocervical instability? Atlantoaxial instability will generally imply axial hypermobility of the atlantoaxial joint itself, which when symptomatic will result in Bow hunters syndrome (positional compression or damage to the vertebral arteries) or Cock Robin syndrome (positional facetal dislocation without reduction). 2014 Aug;4(3):197-210. doi: 10.1055/s-0034-1376371. Learn about the many ways you can get involved and support Mass General. 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. How is one supposed to know, if no one knows what you have in the first place? That said, yes, it is my opinion that the treatment is nonsense. Typically, complete membraneous ruptures of the CVJ may cause dislocation between the head and neck, resulting in positional dissociation between the the two. Atlanto-axial rotatory fixation. This increased mobility causes headache and cervical pain as well as signs of compression of adjacent neural elements that form cervicomedullary syndrome. See my other articles or YouTube videos for howtos. Patients with legitimate CCI or AAI will generally have intermittent induction of symptoms with full rotation, flexion or extension that resolves in netural position, presuming there is no constant crushing of the brainstem or vertebral artery dissection. TOS is often considered a mere upper limb nerve pathology, but this is not the case. 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. This can happen due to excessive rotation at the joint with gradual worsening (eg., in a patient with Ehler Danlos syndrome or similar), or in combination with rotation and transverse-foraminal stenosis, which is the hole on the side of the transverse processes that the vertebral arteries and veins venture through. doi: 10.1227/NEU.0b013e3182333859. But we must see adequate imaging as well as adequate clinical fulfillment of diagnostic criteria to render these diagnoses; it is not enough to feel neck clunking, upper cervical pain, weakness in the neck or wobbleheaded. 404-256-2633. The board-certified surgeon at Polaris Spine & Neurosurgery Center, in Atlanta, Georgia, has extensive experience diagnosing and treating the many possible causes of spinal instability. Atlantoaxial instability is an uncommon condition of dogs in which there is abnormal movement in the neck, between the atlas (first cervical vertebra) and axis (second vertebra). This is not good medical practice. 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. I diagnosed her with mild (benign) atlantoaxial instability and TOS CVH. Eur J Pediatr. 2014). This is Bow hunters syndrome, and may be caused by legitimate atlantoaxial instability. Some have proposed 2mm of translational difference, but this is completely unreliable in my opinion and exprience. What muscles would need to be strengthened to prevent the ADI from opening up? A common but severely ignorant misunderstanding that some clinicians make (the patient cannot be blamed for thinking like this, but the clinician should set it straight), is the notion that mild to moderate ligamentous instabilities makes the neck (or the whole body for that matter) tense up to protect against the ligamentous instability, even though there are minimal or no clear MRI findings to support this notion, and that this somehow causes all of the patients symptoms. In less severe cases, physical therapy can also help. Knowing this it allows to anticipate any possible problems in the postoperative period. Gweon HM, Chung TS, Suh SH. Supine cervical MRI including T2-w sagittal-oblique sequences at 2mm slice thickness (disc and foraminal health is best evaluated on a supine MRI). Surgical management is recommended for those with severe signs and for those who have tried and failed medical management. My experience has been that these approaches do not work, and certainly do not cause long term results. This webpage is intended to provide health information so that you can be better informed. The doctor will tell you which sports and activities are safe for your son/daughter. Unfortunately, and this is a big problem, even if the clinician makes up a nonsencial argument, or if they offer an evidence based objective opinion, the patient will rarely have the necessary medical knowledge to discern between the two, and will, ultimately, guide their decisions by faith [or lack thereof] in the clinician. 2014 Apr;5(2):59-64. doi: 10.4103/0974-8237.139199. If this was the case, ie., if the brainstem and medulla was being stretched, then the patient would highly likely get neurological symptoms that improve with extension and worsen with flexion (as patients with legitimate tethered cord syndrome do), and would certainly have a positive Slump test, a test which stretches the spinal cord. Atlantoaxial instability treatment Contact Dr. Gilete C1 C2 fusion surgery Contact Dr. Gilete Our commitment to reliable health and medical information on the internet This site complies with Request Appointment. Last Update [site_last_modified date_format=Y-m-d H:i:s]. It means that the instability is, or will probably, shortly, become bad enough to carry the potential to damage nerves or blood vessels. 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. Beware that suboccipital pain, espeically if your imaging is normal, is a very common sympton in thoracic outlet syndrome, and is actually a migraine variant. All conventional things like heart and lung problems, MS, cancer, infections etc. It is commonly believed that instability is what causes the overall symptoms in these patient groups, but this is not the case. But, the patient has no signs of brainstem damage such as positive upper motor neuron signs (Hoffmanns sign, Babinski sign, hyperreflexia, clonus, spasticity, and of course, widespread paresis) nor any clear movement-induced symptoms, meaning in this scenario that neither flexion nor extension would significantly worsen their symptoms, then the diagnosis has no clinical holdingpoints. Atlantoaxial subluxation frequently occurs in ligamentous and articular hypermobility syndromes such as Ehler Danlos 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! There are no exercises that can help an instability like that. Get the latest news, explore events and connect with Mass General. 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. 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 zen , nal , Avcu S. Flow volumes of internal jugular veins are significantly reduced in patients with cerebral venous sinus thrombosis. Be sure to understand the mechanism of induction of symptoms in AAI and CCI before jumping on this potentially dangerous, and often financially devastating bandwagon! Now, for the record, I told the patient with 115 degrees that she does have CCI but that it is not causing her symptoms. 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. And, although there was zero evidence of brainsstem compression, she did indeed have subluxation of atlantoaxial joints with around 10% of overlap when turning to the side. This 2009 Sep;11(3):326-9. doi: 10.3171/2009.4.SPINE08689. This, with or without accompanied neurological symptoms, be it vascular or neurological. In such a case, to avoid foreseeable medullary damage, one may reasonably opt for fusion as preventative surgery, because the medulla, once damaged, does not always recovery after surgery. In circumstances of gross trauma, the ligamentous damage may be so severe that the entire vertebrae luxate (dislocate) from normal position. Booking 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. PMID: 24475346; PMCID: PMC3899735. Epub 2019 Jun 21. This can also damage the brainstem and produce symptoms similar to what is described above. Moreover, I have heard numerous similar stories from other patients. I recommend doing this with a neuro-ophthalmologist, not a general ophthalmologist or opticician, as the findings are often missed. Burry HC, Tweed JM, Robinson RG, Howes R. Lateral subluxation of the atlanto-axial joint in rheumatoid arthritis. Evaluation of the Cause of Internal Jugular Vein Obstruction on Head and Neck Contrast Enhanced 3D MR Angiography Using Contrast Enhanced Computed Tomography. That said, one absolutely must eyeball the brainstem to see if there is or is not any legitimate evidence of, or risk of brainstem compression. Donald Corenman, MD, DC. I have not receiving anything that comes close of what they produce. This, again, prompted the more than 1000 euro consultation with the upright imaging center in a large european country. Dashti SR, Nakaji P, Hu YC, Frei DF, Abla AA, Yao T, et al. This can also promote anterior dissociation of the head which will lead to an abnormally high basion-axial interval (BAI Harris measurement) of more than 12mm (Ross & Moore, 2015). We'll assume you're ok with this, but you can opt-out if you wish. The patient may seek out their GP or a local neurosurgeon who will, usually, and usually rightfully so, dismiss these claims, as the patients imaging is normal and also lack neurological signs that would fit with neurovascular compromise. If nicely timed, around 20 secs after infusion, beautiful visualization of both arteries and veins is permitted). 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). Type D would generally involve a dens fracture as the atlas migrates posteriorly, along with facetal luxation and capsular rupture. These are typical signs of craniovasculo-hypertensive disorders. English +34 93 220 28 09 Espaol +34 93 198 34 24 In such a case, UMN symptoms and signs would be expected as well. This is really more of a poor posture/misalignment problem than a case of instability (Larsen 2018), but because it is a legitimate upper cervical problem then I will still mention it in this article. AAI and CCI are diagnoses that mainly cause the risk for either brainstem damage or injury to the arteries that supply the brain with blood, and this can cause paralysis or stroke if left untreated in cases where there is legitimate evidence for pathology. If its caused by rotation (rare), manipulation may temporarily improve jugular outlet passage, but it will not last. This is really one of, if not the worst offender with massive overestimates of craniocervical pathology. BDI, ie. DOI: 10.3171/2015.1.FOCUS14791. The joint between the upper spine and base of the skull is called the atlanto-axial joint. 1927;11(1):155157. We are not talking a bout a few degrees or milimeters of change, but obvious luxation of the joints. J Craniovertebr Junction Spine. 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. 1963). 1978 Dec;37(6):525-8. doi: 10.1136/ard.37.6.525. Slow development of movement skills, headache, and limb weakness have all been attributed to loose ligaments and overly moveable joints connecting the head and neck. Surgical reduction and fixation would be the only appropriate treatment. I consulted with her and reviewed her imaging: The quality of the images, first and foremost, was very low. We have remained at the forefront of medicine by fostering a culture of collaboration, pushing the boundaries of medical research, educating the brightest medical minds and maintaining an unwavering commitment to the diverse communities we serve. (Fixed rotatory subluxation of the atlanto-axial joint). Your email address will not be published. Acta Otolaryngol. 2008). 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. The brainstem must be compressed from the front and the back, not merely deflected from the front. Atlantoaxial fixation: overview of all techniques. These cookies will be stored in your browser only with your consent. to get a better impression of its actual thickness. 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, of course, must be evaluated on a case-to-case basis. In severe cases, I recommend postural corrections (appropriate, not generic) along with styloidectomy and transversectomy. For TOS CVH the patient will generally feel better when stress is reduced along with taking beta blockers (confer with your doctor). 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. A critical view on the overdiagnosis of AAI/CCI. 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. Diagnostic markers for occult craniovascular congestion. It does certainly insinuate some instability and ligamentous laxity, and can certainly result in greater level of wearing and tearing of the facet joints and causing some neck pain and joint effusions, but it can not be said to be any form of sinister AAI or CCI due to lacking neurovascular conflicts. 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). For more information about these cookies and the data
If there is a 1mm listhesis, however and the patient has no neurological symptoms and the medulla is utterly free of compression, then performing fusion is completely unnecessary. It is important to understand that the size of the facets is what determines what degree of rotation would be excessive. Thus, I recommend the following studies for craniovenous hypertension and TOS CVH: Craniovasculo-hypertensive disorders (mainly IIH, TOS CVH (!) 2014 Feb;11(1):75-82. ncbi.nlm.nih.gov/pubmed/24321024, Higgins JN et al. Why would you jump to the worst possible explanation, and especially when lacking apt evidence? In 18 patients, dynamic images showed vertical, mobile and at-least partially reducible atlantoaxial dislocation. What does this mean? This madness must stop. The General Hospital Corporation. Kjetil Larsen is a Researcher and a injury rehabilitation specialist, and is the owner of MSK Neurology. Another patient was told by a well-known pain physician in the US that she had brainstem compression and required several expensive prolotherapy procedures. 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. 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). In people with Down syndrome, the ligaments (connections between muscles) are lax or floppy. 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. Because of its role in movement, it is, unfortunately, commonly injured. This can result in AAI where the bones are less stable and can damage the spinal cord. En este folleto, aprender sobre la IAA y cmo afecta a las personas con sndrome de Down. 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). To schedule an appointment, call one of the offices, or book an appointment online. 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. Atlanto-axial instability (AAI) is a condition that affects the bones in the upper spine or neck under the base of the skull. These problems will mainly endanger the brainstem. 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). Traumatic ligamentous ruptures or gradual deterioration of joint stability may cause basilar invagination, which is a degenerative process causing the odontoid process to graduall migrate into the head via the foramen magnum. Facetal locking with rigid torticollis (Cock Robin syndrome) or similar, in cases where there is no neurological compromise, is less dangerous. Search for condition information or for a specific treatment program. Therefore, when I hear about patients being operated on with no other abnormality than a CXA of 140 degrees, my opinion is that this is reckless butchery. This iatrogenic practice must come to an end. Magnetic resonance imaging assessment of the alar ligaments in whiplash injuries: a case-control study. Atlantoaxial malalignment is best visualized on a lateral view. had been excluded by her primary care physicians and local hospital. 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. 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. Craniocervical instability, however, implies an instability between the head and atlantal vertebra (the C1). PMID: 19769514. PMID: 25083363; PMCID: PMC4111952. From the beginning, the patient doubted my diagnosis that this was a craniovascular problem because she felt pain in the suboccipital area, had cracking and clunking, and felt compatible with several things she had read online and on facebook forums. 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. De Kleyn A, Nieuwenhuyse P. Schwindelanfalle und Nystagmus bei einer bestimmten Stellung des Kopfes. I very often receive upright MRI reports where the rotation is completely normal, and the patient is still diagnosed with AAI. It is different from other joints in the vertebral Dr. Vicen Gilete, MD, Neurosurgeon & Spine Surgeon. Atlantoaxial Instability Treatment. Risk in asymptomatic patients: If the patient has craniovertebral dissociation either due to anterior or superior migration of the head in relation to the cervical column, one may argue that there is a risk for traction injury to the brains blood supply even in cases where the patient has no obvious induction of symptoms upon flexion-, extension or rotation, and has no imaging that demonstrates neurovascular conflict (eg., BHS or positional brainstem compression). If the latter, could be JOS obstruction, or could be placebo. Surgical options, sometimes including relevant-level fusion, may be warranted in these circumstances. 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. The atlantoaxial segment consists of the atlas (C1) and axis (C2) and forms a complex transitional structure bridging the occiput and cervical spine. 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). 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. Symptoms of brainstem compression are respiratory crisis and quadriplegia, but can also manifest more diffusely. -Mummaneni PV, Haid RW. Atlantoaxial instability is a congenital neurologic condition predominantly affecting toy breed dogs. Patients with rotary subluxation will develop torticollis and will generally appear fixed/rigid upon physical exam and may not be able to rotate their necks at all. I recommend sticking to clinics that have good reputations and good imaging protocols. The brainstems were completely void of evidence for compression in both cases, and there was no evidence of signal changes (consistent with brainstem damage) on MRI. And, she still had the same symptoms! 2019) have documented numerous symptomatic cases of jugular vein stenosis at the craniovertebral junction. Thus, beware that a low clivo-axial angle (CXA) is often overinterpreted and abused as supportive evidence. Jugular outlet obstruction is commonly seen in patients with upper cervical horizontal facetal misalignment, and especially if they have broad transverses processes or a posteriorly angulated styloid process (Gweon et a. A CTV is preferable, but a general neck CT will also do if you have sensitive kidneys and would like to avoid contrast infusion. Diagnostic imaging: Spine, 3rd edition. In most circumstances, even if there is poor overlap but no evidence of frank facetal luxations (clinical history or with provocation), then conservative therapy can usually prevail in management.
