An X-ray is low-cost and low-risk, but it does not always tell whether a person has AAI or not. The deep neck flexors should not engage as this lessens the compression. 2009), but this is extremely rare. A general neck MRI is usually a good idea and may show some arthritis in the atlantoaxial and atlanto-occipital joints along with minor intra-articular effusions, suggesting irritation of the joints. 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). We examined 404 patients with this chromosome disorder and observed their atlanto-dens intervals and spinal canal widths to be significantly different from children without Down syndrome. Identifying The Signs Of Cervical Instability. PMID: 18708935. our TOS CVH paper (Larsen et al 2020). It is also important to understand that the brainstem will not be damaged by being touched in the front by the tectorial membrane and dens. We are committed to providing expert caresafely and effectively. Atlanto-axial instability is a potentially dangerous condition where the ligament between the atlas (C1`) and axis (C2) vertebrae at the top of your neck is partially torn. 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. the basion-dens interval, is the distance between the tip of the clivus and tip of the C2. The CXA was 138 degrees and the Grabb-Oakes measurement was 8,3mm. 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. 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. The problem, in the patients eyes, may be a lacking reasonable counter-argument and counter-diagnosis that would explain his or her symptoms, which then prompts the patient to seek out alternative health care. Neurol India. I believe that most of these practitioners mean well. 2005 Dec;53(4):408-15. Review. In severe cases, I recommend postural corrections (appropriate, not generic) along with styloidectomy and transversectomy. Rev. It is advisable to obtain just a lateral view first. This, again, prompted the more than 1000 euro consultation with the upright imaging center in a large european country. 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. Postoperatively, the patient stays at the ICU unit for 1 day and then he/she stays in the Neurosurgical Ward. And if yes, do they completely normalize when resuming neutral position? Spine (Phila Pa 1976). Basil R. Besh, M.D. This pain tends to get worse with stress and with high heart rates, and are often also worse in the morning after lying down. These problems will mainly endanger the brainstem. Patients with severe ligamentous compromise and a risk for actual dangerous secondary potentially pathologies, must have instability so aggressive that it can cause damage to the brainstem or adjacent cerebro-arterial supply. Claims of three, four or even five-level spondylolisthesis due to a 50 micrometer (0.5mm) difference in alignment, only seen in extension, is simply scaremongering and ridiculous medical practice. Contact, Terms & conditions 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. The bones are susceptible to fracture from high-energy impact such as falls or car accidents, especially in the elderly. In other words, the vertical distance between the head and the spine. If the patient has a Grabb-Oakes of 18mm, however, and the transverse ligament is ruptured with the dens compressing the brainstem from the front and pushing it into the lamina behind it, then this is an emergency that requires timely surgical decompression. In 18 patients, dynamic images showed vertical, mobile and at-least partially reducible atlantoaxial dislocation. 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. 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. This, with or without accompanied neurological symptoms, be it vascular or neurological. He specializes in the treatment of chronic pain and has developed several distinctive protocols both with regards to diagnosis and conservative rehabilitation of difficult conditions. How is one supposed to know, if no one knows what you have in the first place? 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). -Mummaneni PV, Haid RW. 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 This may not apply for all of them, but it is a common problem which makes this patient group especially susceptible to become perfect victims of medical vulturism. And, fair enough, I do not expect blind trust nor compliance. Henderson FC Sr, Rosenbaum R, Narayanan M, Koby M, Tuchman K, Rowe PC, Francomano C. Atlanto-axial rotary instability (Fielding type 1): characteristic clinical and radiological findings, and treatment outcomes following alignment, fusion, and stabilization. However, as stated, in most cases this is just locked facets that suddenly reduce (realign) with a pop. zen , nal , Avcu S. Flow volumes of internal jugular veins are significantly reduced in patients with cerebral venous sinus thrombosis. A review of the diagnosis and treatment of atlantoaxial dislocations. Mild and often even moderate circumstances of AAI and CCI can be treated with appropriate (specific, not generic) physical therapy to strengthen the muscles that prevent hypermobility. 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. What cervical artificial disc should I choose? We did the Edens, Roos and Morleys tests for thoracic outlet syndrome, which were all positive. We offer diagnostic and treatment options for common and complex medical conditions. Surgical management is recommended for those with severe signs and for those who have tried and failed medical management. AA instability is typically diagnosed by performing radiographs (x-rays) of the neck. When the bones or ligaments of the atlantoaxial complex are injured, the spinal cord is at particular risk for injury, and surgical treatment is often indicated. 1927;11(1):155157. Followup with a dynamic CT, supine MRI or similar to confirm potentially equivocal findings is warranted. (I will post the before- and after images when I return to Colombia in August, as they are on a separated hard drive). Stay put for 30-60 seconds, look for worsening of symptoms while in the test. Musa A, Farhan SA, Lee YP, Uribe B, Kiester PD. Remember that the main dangers of atlantoaxial hypermobility are 1. facetal luxation, and 2., risk for rotational injury to the vertebral artery. Search for condition information or for a specific treatment program. Dysautonomia when standing up is often related to craniovascular problems, whereas difficulty holding the head up suggests mumscular damage. Pain medications and anti-inflammatories are typically also prescribed. The atlanto-axial (AA) joint is the joint between the first (atlas) and second (axis) vertebrae (bones) in the neck. The atlanto-occipital joint allows your head to move up and down, while the atlantoaxial joint lets your head rotate. Patients with AAI CCI will be expected to trigger symptoms only with neck movement (being upright alone is not enough) and resolve (fully) when the neck is held still. Uniondale, NY Location HSS Long Island The Omni. Journal of Neuro-Ophthalmology 2013;33:330337doi: 10.1097/WNO.0b013e318299c292, Alkhotani A. Cerebrospinal Fluid Rhinorrhea Secondary to Idiopathic Intracranial Hypertension. PMID: 19769514. 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. 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. 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. Hopefully, this is the result of ignorance combined with poor clinical workup skills (incompetence) and not mere greed and malevolence. Radiographics 2000;20:S237-50. But opting out of some of these cookies may affect your browsing experience. Copyright Dr Gilete Neurosurgery & Spine Surgery. 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. Craniocervical Instability (CCI), also known as the Syndrome of Occipitoatlantialaxial Hypermobility. These cookies will be stored in your browser only with your consent. Headaches certainly can develop from instability of C1-2. Kjetil has also published several peer-reviewed studies on musculoskeletal and neurological topics. The patient should demonstrate some brainstem symptoms, and may develop quadriparesis if the compression is sufficiently hard and constant. Moreover, I have heard numerous similar stories from other patients. This is Bow hunters syndrome, and may be caused by legitimate atlantoaxial instability. Required fields are marked *. Goel A. Facetal alignment: Basis of an alternative Goels classification of basilar invagination. However, I also told her that she may end up having fixation surgery in the future to prevent foreseeable compressive damage to the brainstem. Postoperative hospital stay is usually around 7 days. The atlantoaxial segment consists of the atlas (C1) and axis (C2) and forms a complex transitional structure bridging the occiput and cervical spine. Upright cervical MRI in flexion, extension and maximal bi-directional rotation. Styloidectomy and Venous Stenting for Treatment of Styloid-Induced Internal Jugular Vein Stenosis: A Case Report and Literature Review. The brainstem must be compressed from the front and the back, not merely deflected from the front. Atlantoaxial subluxation frequently occurs in ligamentous and articular hypermobility syndromes such as Ehler Danlos syndrome. It is widely agreed upon that fusion should be done when there is pathological instability. 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. I will update the article when I am back home in Colombia in the beginning of August. In addition to that we would start treatment for thoracic outlet syndrome. If the brainstem compression is not positional, ie., it is seen even on neutral imaging, then the symptoms would be expected to be constant. In vertical dissociation of the CVJ, the main dangers will similarly as above involve potentially dangerous pulling and pushing on the blood supply to the brain (carotid and vertebral arteries) as well as the brainstem itself, potentially causing dissection of the arteries. I am not saying it is easy. In previous epidemiologic studies, the prevalence of atlantoaxial instability in persons with Down syndrome was found to be between 9% and 31%. Anaesth Pain & Intensive Care 2018;22(2):238-242. Abbreviations: BDI: basion dens interval, CXA: clivo axial angle, BAI: basion-axial interval, ADI: Atlantoaxial interval. 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). Atlanto-axial instability (AAI) is a condition that affects the bones in the upper spine or neck under the base of the skull. This, however, is very rarely the case with this patient group in my experience. If unavailable, a CT angiogram can be used, but is less sensitive. Necessary cookies are absolutely essential for the website to function properly. Must be carefully evaluated and correlated with the patients symptoms). The success rate of this surgery is 80% or greater; however, there are many potential complications and a mortality rate of 5-10%. Some have proposed 2mm of translational difference, but this is completely unreliable in my opinion and exprience. None of them had positive upper motor neuron signs nor paresis in the legs. The main scope of the below studies is to 1. exclude neurovascular conflict, and 2., to look for legitimate signs of instability be it with or without neurovascular conflicts, in order to determine degree of affliction, prognosis, and treatment plan. Hopefully, this piece will prevail in explaining logical arguments for legitimate findings in CCI and AAI, and therein lead to a gradual decline and prevention for related misdiagnosis. Epub 2014 May 22. Knattlia 2, 3038 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. Once the diagnosis of atlantoaxial instabilityis made, one should consult the neurologist, neurosurgeon, and a geneticist if the patient is a child. Pearls and Other Issues The atlantoaxial segment consists of the atlas (C1) and axis (C2) and forms a complex transitional structure bridging the occiput and cervical spine. It is, technically, possible to perform traction, reduction and fusion to obtain the same result, but this would be like killing a fly with a canon. This is reasonable. Atlantoaxial instability (AAI) is a potential complication of all forms of EDS. This is a major component in the workup for TOS CVH). Ultimately, the reader must discern for themselves. For TOS CVH the patient will generally feel better when stress is reduced along with taking beta blockers (confer with your doctor). Diagnosis is often based on survey radiographs, alth Atlantoaxial Instability Epub 2019 Jun 21. 10 things you should know about Cervical Disc Replacement. This is no longer true. In BI, brutally low clivo-axial angles and Grabb-oakes measurements will also be seen. This website uses cookies to improve your experience while you navigate through the website. BDI, ie. 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. My poor baby has become completely lame and incontinent in the last 48 hours. In patients with Ehler Danlos syndrome, instability is present frequently in several segments, generally C0-C1-C2 (from occipital to axis). 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. 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. Thus, the patients in the rotary subluxation group are expected to present with severe and sudden neck pain as well as rigidity to the extent of being unable to move the neck. 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). Once in the Operating Room, surgery is performed under general anesthesia, with Neurophysiological monitoring (SSEP somatosensory evoked potentials), neuronavigation guidance and intraoperative fluoroscopy guidance. Atlantoaxial malalignment is best visualized on a lateral view. Epub 2020 Oct 16. In my experience, we would expect to see at least 20mmHg maximum venous pressures. 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. 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 Safe Care CommitmentGet the latest news on COVID-19, the vaccine and care at Mass General.Learn more. 2020). 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. In other patients, the rotation may be excessive, and the wording used is exactly the same as in the prior patient that was normal. If you have an atlanto-dens interval (ADI) of 5mm or greater, you have instability by definition. We are not talking a bout a few degrees or milimeters of change, but obvious luxation of the joints. Li M, Gao X, Rajah GB, Liang J, Chen J, Yan F, et al. 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. The same applies for conservative strategies to reduce internal jugular vein compression. This madness must stop. 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 Horizontal misalignment of the facet joints often cause dorsal migration of the C0 and C1 facets which cause approximation of the styloid process and the C1 transverse processes. Call 314-362-3577forPatient Appointments. collected, please refer to our Privacy Policy. Knowing this it allows to anticipate any possible problems in the postoperative period. Dissection of the vertebral and carotid arteries is fairly rare and can be excluded through a doppler ultrasound or CT angiogram. For example, if the patient blacks out every time she turns her head to the left, a followup dynamic catheter angiography could be done, and may demonstrate high-grade stenosis of the vertebral artery when turning to the left. This Atlas screws are generally placed in the lateral masses. Just anterior to the transverse process in patients with normal necks, emerge the internal jugular veins as well as the glossopharyngeal, vagus and accessory nerves. 2014). Upright MRI has very low quality and because of this, there is a lot of guesswork involved in its interpretation. This is a component of TOS CVH in most circumstances, in my experience, but can certainly scare the patient into believing that they have sinister CCI or AAI due to the location of the pain along with heavy cracking and other symptoms. 2-Atlantoaxial instability, levels C1-C2 (atlas-axis). In less severe cases, physical therapy can also help. 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. This is not dangerous, but can cause some popping, restriction in movement, and some pain upon articulation. Gweon HM, Chung TS, Suh SH. AAI is less common in adults with Down syndrome. The diagnosis can be made by means of an Upright MRI (magnetic Resonance Imaging) or with a cervical CT scan with 3D reconstruction. Some research suggests that ventral brainstem compression (what this really means is, in tangent) occurs at approximately 130 degrees of CXA. If your child has symptoms of AAI, the doctor will suggest an X-ray. 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. For example, if there is a C4-5 anterolisthesis with resultant chronic radiculopathy, C4-5 ADCF would often be utilized as operative treatment. KL TRENING & REHAB Dashti SR, Nakaji P, Hu YC, Frei DF, Abla AA, Yao T, et al. 2012). Because of its role in movement, it is, unfortunately, commonly injured. Would need a flexion extension MRI and correlate to the patients symptoms. Fielding JW, Hawkins RJ. These cookies do not store any personal information. Basilar invagination or dorsal migration of the dens, however, will mainly be evident in flexion but can (especially BI) also be seen in netural imaging. In the cases where it is not possible to obtain autologous bone graft, heterologous graft (artificial bone) may also be used. Accessory nerve compression can cause weakness of the trapezius and sternocleidomastoid muscles, but can also cause cervical dystonia. As stated, although rooted in postural dysfunction, this is not really a problem of pathological instability, and therefore I dont recommend neck fusion to treat this problem. 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. Brainstem compression, when symptomatic, will usually cause quadriparesis along with phrenic nerve palsy. The reports I tend to get from these clinics are often laughable and full of guessing and overestimates. Facetal locking with rigid torticollis (Cock Robin syndrome) or similar, in cases where there is no neurological compromise, is less dangerous. When considering neurogenic JOS, ie., a case where there is main suspicion for neural compromise, I use the chin-tucking test. had been excluded by her primary care physicians and local hospital. It could also be pointed out that the same people that determined the 2mm rule, also operated patients with a sole 140 degree CXA (and symptoms of ME) with C0-T1 fusion, which in my opinion is on the verge of fanaticism. DMX. Ann Rheum Dis. It is better to let your doctor know if your son/daughter is having symptoms. Elsevier Publishing. 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. 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. Learn about the many ways you can get involved and support Mass General. 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. Neurologic signs of a cranial cervical myelopathy typically present at a young age and can range from cervical pain (hyperesthesia) to paralysis. The ligaments holding the bones together can also be injured in trauma, or weakened in certain inflammatory conditions such as rheumatoid arthritis or Downsyndrome. Acta Otolaryngol. to analyze our web traffic. 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. TOS is often considered a mere upper limb nerve pathology, but this is not the case. Please understand that no matter how bad you feel, pursuing the wrong diagnosis will not help. If the symptoms happen along with aggressive neurological symptoms, however, or if your neck locks up in rotary fixation, greater concern could be applicable. Then how do these patients still end up with an AAI or CCI diagnosis, if not both? The General Hospital Corporation. 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. Radiologic spectrum of craniocervical distraction injuries. Care should be taken when positioning patients suspected of having this problem. TOS is also a common cause of dyspnea (respiratory difficulty), although these patients will have normal blood oxygen levels, which was also the case here. A review of the diagnosis and treatment of atlantoaxial dislocations. J Bone Joint Surg Am. In the Axis, pedicle screws are usually the first choice although, depending on the patients anatomy, placement of isthmic screws may be considered. None of these tests would be able to reproduce her symptoms if they were stemming from AAI or CCI. We'll assume you're ok with this, but you can opt-out if you wish. The joint between the upper We also use third-party cookies that help us analyze and understand how you use this website. The aim of surgery is to stabilize the AA joint internally to prevent future spinal cord injury. Washington University neurosurgeons have extensive experience treating problems in this area and are recognized nationally as experts in providing innovative treatments for this unique and complex area of the neck. Both measurements tend to worsen with neck extension. Booking Global Spine J. Last Update [site_last_modified date_format=Y-m-d H:i:s]. Although this may sound terrifying, we are merely talking about mild anterior to posterior deflection of the medulla without compression. Most imaging is tends to be normal, except certain craniovascular workups, especially a CTV of the head, TOS workups, and doppler of the carotid and vertebral arteries (not positive for hypoperfusion, but hyperperfusion). 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. Call us: 212.774.2837 Why rely on Washington University experts for treatment of your atlantoaxial instability? You also have the option to opt-out of these cookies. 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. What muscles would need to be strengthened to prevent the ADI from opening up? But opting out of some of these cookies may affect your browsing experience. 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.
