Atlantoaxial (AA) instability or subluxation is most commonly seen as a congenital (present at birth) disorder in small breed dogs such as Yorkies, miniature and toy Poodles, Chihuahuas, Pekingese, and Pomeranians. Burry HC, Tweed JM, Robinson RG, Howes R. Lateral subluxation of the atlanto-axial joint in rheumatoid arthritis. This is not dangerous, but can cause some popping, restriction in movement, and some pain upon articulation. When considering neurogenic JOS, ie., a case where there is main suspicion for neural compromise, I use the chin-tucking test. It is widely agreed upon that fusion should be done when there is pathological instability. If unavailable, a CT angiogram can be used, but is less sensitive. Post count: 8446. Type D would generally involve a dens fracture as the atlas migrates posteriorly, along with facetal luxation and capsular rupture. 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. Atlantoaxial malalignment is best visualized on a lateral view. En este folleto, aprender sobre la IAA y cmo afecta a las personas con sndrome de Down. Albeit still a surgically treated problem. 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. Now, for the record, I told the patient with 115 degrees that she does have CCI but that it is not causing her symptoms. Contact, Terms & conditions 2019) have documented numerous symptomatic cases of jugular vein stenosis at the craniovertebral junction. Wake up and walking begins on the second day after surgery. All patients were treated with atlantoaxial plate and screw fixation using techniques described in 1994 and 2004. AAI is less common in adults with Down syndrome. If its caused by rotation (rare), manipulation may temporarily improve jugular outlet passage, but it will not last. 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. Pain medications and anti-inflammatories are typically also prescribed. No improvement! 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. Dr. Nic Gay and Dr. Masi Reynolds specialize in getting to the root cause of the problem It will rarely cause frank luxation, however where the facets dislocate and lock laterally. 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. 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. Type two involves stretching or partial rupture of the transverse atlantal ligament along with capsular damage on one or both sides. 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. It mainly consists of the posterior fusion of the affected vertebrae, in this case, the atlas (C1) and the axis (C2). Another patient was told by a well-known pain physician in the US that she had brainstem compression and required several expensive prolotherapy procedures. I have not receiving anything that comes close of what they produce. 2009), but this is extremely rare. 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]. But this is rarely the case in my experience. First, need I mention the notion that there is tremendous money in this patient group, and that if treatment goes wrong, becuase they have already burned their bridges with their GPs, no one will listen nor care? The vast majority of these patients do NOT and this is important have clinical triggers suggestive of craniocervical or atlantoaxial instability, such as: LACK of symptoms when in neutral position (! PMID: 18708935. This website uses cookies to improve your experience. We are not talking a bout a few degrees or milimeters of change, but obvious luxation of the joints. Gweon HM, Chung TS, Suh SH. Request an appointment or second opinion, refer a patient, find a doctor or view test results with MGfC's secure online services. Last Update [site_last_modified date_format=Y-m-d H:i:s]. zen , nal , Avcu S. Flow volumes of internal jugular veins are significantly reduced in patients with cerebral venous sinus thrombosis. 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. 2000). Exam for bow hunters syndrome is done dynamically, but thats aother exam. BHS implies rotational compression of the vertebral arteries, which are two out of four arteries that supply the brain (two internal carotid and two vertebral arteries). 1-Craniocervical instability, levels C0-C1 (Occipital-atlas). 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). Fundus exam (must be properly zoomed, must be exported in high digital quality and resolution). 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. Necessary cookies are absolutely essential for the website to function properly. If someone has an ADI of 4.5mm, can this be treated via physical therapy, or is it too much instability? Because this article is, in essence, just another opinion piece, let us then focus on logical reasoning and objective arguments. This category only includes cookies that ensures basic functionalities and security features of the website. I consulted with her and reviewed her imaging: The quality of the images, first and foremost, was very low. Imaging will prove brainstem compression on [flexion/extension] MRI, and an increased atlantodental interval on flexion/extension CT or x-ray. These are typical signs of craniovasculo-hypertensive disorders. Atlantoaxial instability (AAI) is a potential complication of all forms of EDS. Atlas screws are generally placed in the lateral masses. 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. Journal of Neuro-Ophthalmology 2013;33:330337doi: 10.1097/WNO.0b013e318299c292, Alkhotani A. Cerebrospinal Fluid Rhinorrhea Secondary to Idiopathic Intracranial Hypertension. 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. Curr Neurovasc Res. This pain tends to get worse with stress and with high heart rates, and are often also worse in the morning after lying down. About Required fields are marked *. This is a major component in the workup for TOS CVH). The exam should be done lying down, without a neck pillow. 2021 Jun;44(3):1553-1568. doi: 10.1007/s10143-020-01345-9. Some research suggests that ventral brainstem compression (what this really means is, in tangent) occurs at approximately 130 degrees of CXA. But opting out of some of these cookies may affect your browsing experience. A 32 year-old female patient contacted me in 2019 as she had been diagnosed (by a radiologist alone) with craniocervical and atlantoaxial instability. The BDI indicates vertical-, and the BAI horizontal structural integrity. It means that the instability is, or will probably, shortly, become bad enough to carry the potential to damage nerves or blood vessels. medullary) symptoms when looking down, and will tend to improve when pulling the head up and back. However, can we say the same if there is major guesswork involved in the rendering of the diagnosis? Styloidectomy and Venous Stenting for Treatment of Styloid-Induced Internal Jugular Vein Stenosis: A Case Report and Literature Review. What Is Atlanto-Axial Instability (AAI)? I recommend first measuring the degree of rotation between the C1 and C2 by drawing a line from the bifid process to the middle of the anterior aspect of the vertebra, and then another line from the posterior to the anterior tubercles of the C1. Treatment depends on your son/daughters symptoms. 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). 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). 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. Privacy policy, Do you really have atlantoaxial and craniocervical instability? At Mass General, the brightest minds in medicine collaborate on behalf of our patients to bridge innovation science with state-of-the-art clinical medicine. Ann Rheum Dis. Myran R, Kvistad KA, Nygaard OP, Andresen H, Folvik M, Zwart JA. 333 Earle Ovington Blvd, Suite 106. Ujifuku K, Hayashi K, Tsunoda K, Kitagawa N, Hayashi T, Suyama K, Nagata I. Positional vertebral artery compression and vertebrobasilar insufficiency due to a herniated cervical disc. These cookies will be stored in your browser only with your consent. My experience has been that these approaches do not work, and certainly do not cause long term results. In the congenital form of AA instability, the animal is born with abnormal bony or ligamentous connections between the first two vertebrae in the neck. Suboccipital symptoms that occur only with cracking, if the MRI shows arthritis or joint effusion, especially if the neck locks in rotary fixation, then this could be a case of legitimate AAI or CCI. Necessary cookies are absolutely essential for the website to function properly. 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. Atlantoaxial instability will generally imply axial hypermobility of the atlantoaxial joint itself, which when symptomatic will result in Bow hunters syndrome (positional Training is done carefully twice per week. De Kleyn A, Nieuwenhuyse P. Schwindelanfalle und Nystagmus bei einer bestimmten Stellung des Kopfes. Fielding JW, Hawkins RJ. Common findings: Ovalization of the orbitae, dilated optic nerve sheaths, pituitary concavity, Chiari malformation, tight brain appearance, jugular vein compression with or without white-vessel signs, dilation or narrowing of the lateral and possibly third ventricles, periventricular ependymal T2 FLAIR hyperintensities), Neck MRI (general evaluation of the neck integrity), CT angiogram of the head neck and subclavian arteries with the arms raised (contrast infusion via femoral vein. In severe cases, I recommend postural corrections (appropriate, not generic) along with styloidectomy and transversectomy. Kjetil has also published several peer-reviewed studies on musculoskeletal and neurological topics. Atlantoaxial instability and craniocervical instability are spinal manifestations directly due to ligament laxity. Hopefully, this is the result of ignorance combined with poor clinical workup skills (incompetence) and not mere greed and malevolence. This is not good medical practice. collected, please refer to our Privacy Policy. 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. Tambin conocer las causas, los signos y los sntomas de la IAA. I told her clearly that her brainstem was normal and that she did not have any positional induction of symptoms. In addition to reproducible clinical triggers (positions), the patient should preferably undergo a dynamic catheter angiography of the neck. However, if the patient has symptoms regardless of being in rotation or not, and has never had a case of alantoaxial rotary fixation, then there is no evidence that this is the cause of the patients symptoms, even if it, indeed, may be a bit loose. And if yes, do they completely normalize when resuming neutral position? Lack of signal change in the cord, and especially when it is not being compressed from both sides, is not a case of brainstem compression, Mild to moderate ligamentous compromise in cases where all measurements are normal or nearly normal, and there is no neurovascular compression, is generally NOT a surgical indication nor an indication for aggressive treatment. DMX. The diagnosis can be made by means of an Upright MRI (magnetic Resonance Imaging) or with a cervical CT scan with 3D reconstruction. Save my name, email, and website in this browser for the next time I comment. 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. 2011 Apr;15(1):41-47. In the Axis, pedicle screws are usually the first choice although, depending on the patients anatomy, placement of isthmic screws may be considered. 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. Safe Care CommitmentGet the latest news on COVID-19, the vaccine and care at Mass General.Learn more. This webpage is intended to provide health information so that you can be better informed. This is Bow hunters syndrome, and may be caused by legitimate atlantoaxial instability. Radiologic spectrum of craniocervical distraction injuries. Congenital, inflammatory, traumatic, Diagnosis is often based on survey radiographs, alth Atlantoaxial Instability These problems will mainly endanger the brainstem. Now, the I was told is clearly second-hand information, and I cannot guarantee its accuracy. DOI: 10.3171/2015.1.FOCUS14791. Remember that the main dangers of atlantoaxial hypermobility are 1. facetal luxation, and 2., risk for rotational injury to the vertebral artery.

The General Hospital Corporation. 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. What cervical artificial disc should I choose? We offer diagnostic and treatment options for common and complex medical conditions. 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. Dr. Christopher Williams | 07/09/2020. DOI: https://doi.org/10.35975/apic.v24i1.1230. Typically, complete membraneous ruptures of the CVJ may cause dislocation between the head and neck, resulting in positional dissociation between the the two. Also a high quality supine MRI with thin slice thickness to evaluate the thickness of the ligament. Spine (Phila Pa 1976). Atlantoaxial instability (AAI) is the term for increased motion at the joint between the 1st and 2nd cervical vertebrae (the atlas and the axis). Diagnostic markers for occult craniovascular congestion. Lateral bowing of the inferior atlantal facets in netural position is a sign of transverse atlantal ligament laxity. J Korean Soc Magn Reson Med. Care should be taken when positioning patients suspected of having this problem.

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. Acute or chronic spinal cord compression causing clinical signs consistent with an upper cervical myelopathy can result from this instability [2]. If there are no symptoms, then what reuslts are you talking about? 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. Org. A lot of things that cause temporary results are just placebo. 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. 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. 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 Secondly, and perhaps more importantly, the extent of facetal overap must be measured. Does it matter whether these are done laying or sitting down? Surgical reduction and fixation would be the only appropriate treatment. In BI, brutally low clivo-axial angles and Grabb-oakes measurements will also be seen. Now, what if there is no frank compression nor clinically medullary signs and triggers, but there is a very small space both infront and behind the medulla that has been gradually getting worse. Moreover, I have heard numerous similar stories from other patients. Because it doesnt work most of the time, and doesnt cause any lasting results. 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. Request Appointment. In BI, the compression tends to be constant. 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. She was also said to have ventral brainstem compression, which particularly scared her due to her difficulties with respiration. 2015. Traditional cases of atlantoaxial instability and craniocervical instability require obvious imaging findings with strong clinical correlation, and, when its criteria are met, are certainly treated (operated) in any skilled and compatible neurosurgical ward. This site complies with the HONcode standard for trustworthy health information: verify here. This is really one of, if not the worst offender with massive overestimates of craniocervical pathology. Uniondale, NY Location HSS Long Island The Omni. 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. Additionally, spinal instability in the form of spondylolisthesis our TOS CVH paper (Larsen et al 2020). Goel A. Facetal alignment: Basis of an alternative Goels classification of basilar invagination. What muscles would need to be strengthened to prevent the ADI from opening up? 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. 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. Copyright 2007-2023. Acta Otolaryngol. 2008 Aug 15;33(18):2012-6. doi: 10.1097/BRS.0b013e31817bb0bd. 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). Surgery to address problems in this area can be risky. 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). La inestabilidad atlantoaxoidea (IAA) es una enfermedad que afecta los huesos de la parte superior de la columna vertebral. 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! Kjetil Larsen is a Researcher and a injury rehabilitation specialist, and is the owner of MSK Neurology. My poor baby has become completely lame and incontinent in the last 48 hours. 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. Grabb-Oakes interval is another measurement that is often misunderstood. 14 Postoperative care advices following cervical disc herniation surgery, 4 Predictive factors of the results in Cervical Herniated Disc surgery. It is important to understand that the size of the facets is what determines what degree of rotation would be excessive. Our surgeons provide a full range of treatments including non-surgical options as well as surgical repair. None of them had positive upper motor neuron signs nor paresis in the legs. The atlanto-occipital joint allows your head to move up and down, while the atlantoaxial joint lets your head rotate. Symptoms of brainstem compression are respiratory crisis and quadriplegia, but can also manifest more diffusely. 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. Please understand that no matter how bad you feel, pursuing the wrong diagnosis will not help. 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. The utmost majority of these patients have have normal supine imaging, and many of them also normal or nearly normal upright imaging. If your child has symptoms of AAI, the doctor will suggest an X-ray. I recommend doing this with a neuro-ophthalmologist, not a general ophthalmologist or opticician, as the findings are often missed.
