Radiologic spectrum of craniocervical distraction injuries. I will update the article when I am back home in Colombia in the beginning of August. In reality, in legitimate cases of atlantoaxial or craniocervical instability, the instability may cause a potentially dangerous neurovascular conflict, as mentioned initially, where the brainstem or vertebral arteries can get damaged. This is what I said from the beginning; AAI is not the cause of these symptoms, the exam and triggers do not fit. Elsevier Publishing. Flexion-extension and cervical rotation on both sides should be evaluated. The atlantoaxial subluxation may exist in patients neutral position (without neck movement) or may occur in relation to neck rotation movements (when the patient moves the neck to the right and left). We use cookies and other tools to enhance your experience on our website and In 18 patients, dynamic images showed vertical, mobile and at-least partially reducible atlantoaxial dislocation. Her symptoms, however, did not at all change when changing her neck position and she had never had torticollis. If the latter, could be JOS obstruction, or could be placebo. Followup with a dynamic CT, supine MRI or similar to confirm potentially equivocal findings is warranted. -Mummaneni PV, Haid RW. Explore fellowships, residencies, internships and other educational opportunities. In such cases I tell my patients that, yes, you do have mild AAI, but it is not causing your symptoms. Your email address will not be published. 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. 2015. Dr. Christopher Williams | 07/09/2020. Search for condition information or for a specific treatment program. Clunking, clicking and pain in the upper neck. Burry HC, Tweed JM, Robinson RG, Howes R. Lateral subluxation of the atlanto-axial joint in rheumatoid arthritis. 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 positional (ie., upright. Stay put for 30-60 seconds, look for worsening of symptoms while in the test. 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. 2019 Oct;130:129-132. doi: 10.1016/j.wneu.2019.06.100. Atlanto-axial instability (AAI) is a condition that affects the bones in the upper spine or neck under the base of the skull. 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. PMID: 18708935. 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. I have seen patients with a CXA as low as 110 degrees and still did no have any frank brainstem compression. This, seriously augmented by poor hinge neck postures (Larsen 2018). World Neurosurg. Complete rupture of the transverse atlantal ligament, however, will generally promote dorsal and cranial migration of the odontoid process (the atlantodental interval (ADI) will be increased (> 3,5mm) while in flexion) causing it to compress the brainstem dorsally (in the upper neck), or to migrate into the foramen magnum and compress the brainstem there (basilar invagination), where the tip of the odontoid will be seen far above the Chamberlains line, whereas it in normal patients sits about 2mm below the line. J Craniovertebr Junction Spine. It is also important to know and evaluate patients concomitant diseases or comorbidities which are frequent in patients affected by Ehler Danlos, such as POTS, Mast Activation Syndrome, cardiac abnormalities etc. If it is, however then flexion/extension and rotational imaging to exclude positional facetal luxation is warranted. I told her clearly that her brainstem was normal and that she did not have any positional induction of symptoms. 2012). 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. These cookies will be stored in your browser only with your consent. 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). 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. Call 314-362-3577forPatient Appointments. Please understand that no matter how bad you feel, pursuing the wrong diagnosis will not help. Flexion and extension imaging fails to demonstrate any sort of brainstem compression. 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. The joint between the upper The atlantoaxial complex is primarily responsible forenabling the head to rotate, or turn to the left and right, while also protecting the spinal cord from injury. 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. Sometimes, an X-ray shows AAI when there are no symptoms. 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). Facetal rigidity and dysarticulation is very common in patients with poor cervical postures and functionality of the neck muscles, and especially the muscles that restrict rotation and attach directly onto the spinous or transverses processes in the spine. 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. Postural orthostatic tachycardia syndrome (POTS) and its relation to craniovascular dysfunction, Pectineo-femoral pinch syndrome: A common cause of groin & anterior thigh pain and weakness, Chronic spinal pain and radiculopathy: Diagnostic approach and common imaging pitfalls, Neurogenic genital pain: Pudendal neuralgia and inferior hypogastric plexalgia. 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. An X-ray is low-cost and low-risk, but it does not always tell whether a person has AAI or not. Dysautonomia when standing up is often related to craniovascular problems, whereas difficulty holding the head up suggests mumscular damage. Identifying The Signs Of Cervical Instability. 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. 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. The findings may be quite subtle and are easy to miss outside of dynamic exams. PMID: 749697; PMCID: PMC1000289. 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. A CTV is preferable, but a general neck CT will also do if you have sensitive kidneys and would like to avoid contrast infusion. The triggers would be especially relevant, seeing as various symptoms can heavily overlap between hundreds if not thousands of diagnoses. The success rate of this surgery is 80% or greater; however, there are many potential complications and a mortality rate of 5-10%. #11760. 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. The symptoms will completely resolve when returning to neutral position; usually even a few degrees reduction is enough to normalize flow. Org. Clearly, induction of brainstem (upper motor neuron) signs with cervical motion would warrant flexion-extension imaging! The atlantoaxial segment consists of the atlas (C1) and axis (C2) and forms a complex transitional structure bridging the occiput and cervical spine. Having a strong neck and good posture helps a lot as well (details on what this entails can be read in my article on atlas instability). Eur J Pediatr. This is reasonable. 333 Earle Ovington Blvd, Suite 106. 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. 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. 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 The atlanto-occipital joint allows your head to move up and down, while the atlantoaxial joint lets your head rotate. 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. Knowing this it allows to anticipate any possible problems in the postoperative period. 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. (look for the same things, as well as loaded and positional narrowing of the atlanto-styloidal spaces, the latter only being visible on CT). 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. Atlas screws are generally placed in the lateral masses. Foramen magnum decompression or syrinx manipulation was not performed in any patient. -Dr. Vicen Gilete, MD, Neurosurgeon & Spine Surgeon. 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. Myran R, Kvistad KA, Nygaard OP, Andresen H, Folvik M, Zwart JA. After the preoperative analysis of the Magnetic Resonance Imaging (MRI) and CT scan of each patient, we perform a thin sliced preoperative CT oriented towards neuronavigation that will be carried out during surgery. This, once again emphasized if the patient also does not induce any sinister symptoms in the positions where the alleged instability occurs. Imaging will prove brainstem compression on [flexion/extension] MRI, and an increased atlantodental interval on flexion/extension CT or x-ray. These problems will mainly endanger the brainstem. Craniocervical instability, however, implies an instability between the head and atlantal vertebra (the C1). I see massive amounts of patients with alleged AAI who have normal atlantoaxial facetal overlap, and of course, also lacking clinical correlation. 2008 Aug 15;33(18):2012-6. doi: 10.1097/BRS.0b013e31817bb0bd. Get the latest news on COVID-19, the vaccine and care at Mass General. Surgery to address problems in this area can be risky. The doctor will tell you which sports and activities are safe for your son/daughter. Due to the poor practice integrity that is often associated with DMX imaging, despite these modalities indeed having some utility in certain cases, I cannot recommend having them done unless done in a serious hospital without a financial incentive (ie., without financial connections to the clinician ordering them), and without a very obvious scope of investigation that could not already be seen in MR or CT imaging. Does it matter whether these are done laying or sitting down? However, can we say the same if there is major guesswork involved in the rendering of the diagnosis? If the patient has an elevated Grabb-oakes interval of 10mm and low CXA of 130 degrees, there is some horizontalization (upwards deflection) of the medulla, but no compression from both sides. The BDI indicates vertical-, and the BAI horizontal structural integrity. Early stage) and constant compression (if seen on mri, moderate, if seen on CT, severe) of these structures may occur. We'll assume you're ok with this, but you can opt-out if you wish. Neurol India. 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. 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. Booking Patient resources for the Down Syndrome Program. Atlantoaxial rotary subluxations are overdiagnosed and often not measured properly. In severe cases, I recommend postural corrections (appropriate, not generic) along with styloidectomy and transversectomy. When these muscles get tight (due to profound weakness), due to poor posture and movement patterns, or, as well, in many cases due to head or neck trauma, restricted joint movement will occur and popping and cracking, even loud clunks can occur. DMX. Another common belief is that this mild deflection stretches the brainstem and somehow causes damage. If there are no symptoms, then what reuslts are you talking about? Most cases of mild to moderate unilateral compression, sometimes even intermittent occlusion, is asymptomatic due to contribution from the contralateral VA (Faris et al. Facetal locking with rigid torticollis (Cock Robin syndrome) or similar, in cases where there is no neurological compromise, is less dangerous. Required fields are marked *. Acta Otolaryngol. What is atlanto-axial instability? All patients were treated with atlantoaxial plate and screw fixation using techniques described in 1994 and 2004. November 19, 2014 at 8:19 pm. It is crucial to understand that the general minor instabilities involved in AAI and CCI are not the cause of symptoms. Often times if surgery is required, the bones between C1 and C2 are fused together, requiring less than 48 hours of an in-hospital stay. However, appropriate inclusive criteria must be used to render the diagnoses; subtle findings and the lack of a strong clinical correlation is not enough, and will easily lead to misdiagnosis and related anxiety and suffering. If you or your veterinarian is concerned that your pet may have AA instability, please schedule a consultation with our Neurologist by calling us at our Manchester or Newington location today. had been excluded by her primary care physicians and local hospital. Deliganis AV, Baxter AB, Hanson JA, et al. We can still treat it preventatively, but it wont resolve the symptoms. If the symptoms happen along with aggressive neurological symptoms, however, or if your neck locks up in rotary fixation, greater concern could be applicable. Request an appointment or second opinion, refer a patient, find a doctor or view test results with MGfC's secure online services. PMID: 25083363; PMCID: PMC4111952. Generally, however, in ligamentous laxity, some bowing and lateral hypermobility (evident by lateral flexion overhangs) will almost definitely not result in frank luxations down the line nor do they tend to elicit symptoms from the actual atlantoaxial facet joints. Both neurophysiological monitoring and neuronavigation guidance are safety measures for the patient. Contact, Terms & conditions Global Spine J. J Korean Soc Magn Reson Med. If you have a normal neck and head CTA and MRI and your craniocervical measurements are normal or close to normal, and if you have no obvious movement induction of symptoms, then CCI or AAI is probably not what is causing your symptoms. These cookies do not store any personal information. Curr Neurovasc Res. 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. Rev. Case Rep Neurol 2019;11:295298, Waldock WJ, Higgins NJ, Axon P. A case report of gastroparesis resolved by styloidectomy. Our surgeons provide a full range of treatments including non-surgical options as well as surgical repair. I consulted with her and reviewed her imaging: The quality of the images, first and foremost, was very low. Diagnostic imaging: Spine, 3rd edition. 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. We are committed to providing expert caresafely and effectively. But opting out of some of these cookies may affect your browsing experience. 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. Styloidectomy and Venous Stenting for Treatment of Styloid-Induced Internal Jugular Vein Stenosis: A Case Report and Literature Review. Spine (Phila Pa 1976). This website uses cookies to improve your experience while you navigate through the website. It is not due to mild overall instability that does not cause neurovascular conflicts. 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. 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. 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. It is different from other joints in the vertebral 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). Another diagnostic method used is cervical cineradiology, which records joint(s) movement of the entire occipitocervical, atlantoaxial and subaxial joint system. 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. The problem begins when certain nonsensical articles about CCI and AAI, that do not properly explain relevant clinical correlation nor imaging requirements, but rather, just lists a set of associated symptoms, finds favor in the patient. Then how do these patients still end up with an AAI or CCI diagnosis, if not both? Atlantoaxial Instability Treatment. Look for jugular vein compression, dural sinus and neck vein integrity, exclude typical patholgies such as aneurysms etc., exclude vertebral or carotid dissections, evaluate the thoracic outlet for interscalene, costoclavicular or subpectoral stenosis), Doppler of the carotid and vertebral arteries (look for signs of hypertension, cf. 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. The atlantoaxial joint is normally stabilized by a projection off the axis called the dens, which fits into the atlas, as well as several ligaments between the two bones. There are two causes for the instability, trauma and birth abnormalities. Traumatic instability occurs after forceful flexion of the head, Some have proposed 2mm of translational difference, but this is completely unreliable in my opinion and exprience. 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. 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. 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. Atlantoaxial instability (AAI) is a potential complication of all forms of EDS. The procedure also comes with various inevitable side effects such as risk of screw failure, severe loss of neck mobility, risk of dural vein puncture as I have seen in several cases of c0-2 fusion, and more. If your son/daughter does not need surgery, it is important for him/her to be very careful playing sports or doing other physical activities. Sometimes flexion-extension and rotational imaging is necessary. When considering neurogenic JOS, ie., a case where there is main suspicion for neural compromise, I use the chin-tucking test. Prior to surgery we perform a surgical planning of the intraoperative neuronavigation to confirm the trajectories of screws and special anatomical dispositions of structures. 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. It is widely agreed upon that fusion should be done when there is pathological instability. 3. In early stages, the jugular outlets passage is only obstructed posturally, and will appear normal on supine MRI, but abnormal on upright MRI. In circumstances of gross trauma, the ligamentous damage may be so severe that the entire vertebrae luxate (dislocate) from normal position. You also have the option to opt-out of these cookies. Josy GF, Daily AT. 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). Uniondale, NY Location HSS Long Island The Omni. Neurosurgery. Privacy policy, Do you really have atlantoaxial and craniocervical instability? Maybe they temporary fix some compression? 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. Diagnostic markers for occult craniovascular congestion. 1927;11(1):155157. J Bone Joint Surg Am. are generally useless in most cases? DOI: 10.3171/2015.1.FOCUS14791.

Because it doesnt work most of the time, and doesnt cause any lasting results. PMID: 19769514. If the measurements are within normal limits, the likelihood of dangerous sequelae are low, if not absent. In moderate stages, the MRI will appear abnormal, but the CTV will still appear relatively OK (because the patient tends to be placed on a neck wedge which protracts the head in the CT machine this reduces the compression). 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. zen , nal , Avcu S. Flow volumes of internal jugular veins are significantly reduced in patients with cerebral venous sinus thrombosis. Magnetic resonance imaging assessment of the alar ligaments in whiplash injuries: a case-control study. 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. Dr. Vicen Gilete, MD, Neurosurgeon & Spine Surgeon. 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). 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. 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. That said, yes, it is my opinion that the treatment is nonsense. 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. In addition to reproducible clinical triggers (positions), the patient should preferably undergo a dynamic catheter angiography of the neck. Atlantoaxial (AAI) and craniocervical instability (CCI) are two potentially sinister diagnoses that cause damage to the segmental neurovascular structures due to overmobility of the upper cervical spine. However, I also told her that she may end up having fixation surgery in the future to prevent foreseeable compressive damage to the brainstem. The ligaments involved are the transverse, alar and capsular ligaments. English +34 93 220 28 09 Espaol +34 93 198 34 24 If you or your veterinarian is concerned that your Atlantoaxial instability will generally imply axial hypermobility of the atlantoaxial joint itself, which when symptomatic will result in Bow hunters syndrome (positional This site complies with the HONcode standard for trustworthy health information: verify here. 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.
