atlantoaxial instability specialist

The report claimed that there were signs of ligamentous rupture and bidirectional subluxation upon rotation in the atlantoaxial joints. The aim of surgery is to stabilize the AA joint internally to prevent future spinal cord injury. 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. Due to the instability in the craniocervical junction deformation can occur to the brainstem, upper spinal cord, and cerebellum. the section on bow hunters syndrome. If its caused by rotation (rare), manipulation may temporarily improve jugular outlet passage, but it will not last. This is a major component in the workup for TOS CVH). We use cookies and other tools to enhance your experience on our website and Atlanto-axial instability (AAI) is a condition that affects the bones in the upper spine or neck under the base of the skull. 2020). Post count: 8446. Compare the two to obtain the degree of rotation. 2012 Mar;70(3):E795-9. 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. 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. 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. 2014 Feb;11(1):75-82. ncbi.nlm.nih.gov/pubmed/24321024, Higgins JN et al. This category only includes cookies that ensures basic functionalities and security features of the website. Symptoms of VBI develop rapidly in patients with legitimate and adequate degrees of vertebral artery compression when placed in the triggering position. Accessory nerve compression can cause weakness of the trapezius and sternocleidomastoid muscles, but can also cause cervical dystonia. It mainly consists of the posterior fusion of the affected vertebrae, in this case, the atlas (C1) and the axis (C2). 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). 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. This 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. 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). Get the latest news, explore events and connect with Mass General. He also found that severe misalignment of these joints were often associated with Chiari malformation, basilar invagination, and various other pathologies. A positive test would be interpreted by unbearable head pressure, lightheadedness, worsening of headache, etc., within about 20-30 seconds. Early stage) and constant compression (if seen on mri, moderate, if seen on CT, severe) of these structures may occur. In addition to reproducible clinical triggers (positions), the patient should preferably undergo a dynamic catheter angiography of the neck. 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. This, however, is very rarely the case with this patient group in my experience. 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. 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. 404-256-2633. 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. 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 surgical treatment for Atlantoaxial instability, when it manifests alone without occipitocervical instability, it mainly consists of a posterior fusion of the first cervical vertebra (C1 or Atlas) and the second cervical vertebra (C2 or Axis). A patient with positional brainstem compression due to TAL rupture, for example, will develop neurological (ie. Your email address will not be published. With the increasing dependence on smartphones, computers, and other devices in our modern The diagnosis can be made by means of an Upright MRI (magnetic Resonance Imaging) or with a cervical CT scan with 3D reconstruction. I have not receiving anything that comes close of what they produce. Atlantoaxial instability (AAI) is a potential complication of all forms of EDS. Sometimes, an X-ray shows AAI when there are no symptoms. Diagnosis is often based on survey radiographs, alth Atlantoaxial Instability Faris AA, Poser CM, Wilmore DW, et al.. Radiologic visualization of neck vessels in healthy men. 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. For more information about these cookies and the data https://doi.org/10.13104/jksmrm.2011.15.1.41. Testimonials If the latter, could be JOS obstruction, or could be placebo. 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. Facetal locking with rigid torticollis (Cock Robin syndrome) or similar, in cases where there is no neurological compromise, is less dangerous. Rather, just like with the CXA, it is an indication of the present spinal health status and perhaps also an indicator as to non-surgical prognosis as well as an indicator of likely outcome if nothing is done. Atlantoaxial fixation: overview of all techniques. 914 390 028 Followup, as mentioned above, can be a CTV, volume flow doppler exam, and potentially catheter venography and manometry as one additional confirming pre-surgical step to ascertain actual raised intravenous pressures. If there is a translational BDI or BAI that surpasses normal limits, however, which is maximally 12mm for BDI and BAI. It is different from other joints in the vertebral Why would you jump to the worst possible explanation, and especially when lacking apt evidence? In previous years, doctors thought all people with Down syndrome should have regular X-rays to check for AAI. 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. I diagnosed her with mild (benign) atlantoaxial instability and TOS CVH. 2009 Sep;11(3):326-9. doi: 10.3171/2009.4.SPINE08689. 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). I recommend sticking to clinics that have good reputations and good imaging protocols. This website uses cookies to improve your experience while you navigate through the website. In such a case, however, certain important measurements (not mere CXA (norm: 150-180 degrees) or Grabb-Oakes (norm. Symptoms of brainstem compression are respiratory crisis and quadriplegia, but can also manifest more diffusely. J Bone Joint Surg Am. Copyright Dr Gilete Neurosurgery & Spine Surgery. My poor baby has become completely lame and incontinent in the last 48 hours. Thanks for your help! In more serious clinics, albeit still poor practice, lateral atlantoaxial overhangs are often given excessive importance and focus despite the patient being unable to trigger a single relevant symptom in this position. The success rate of this surgery is 80% or greater; however, there are many potential complications and a mortality rate of 5-10%. 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. If your child has symptoms of AAI, the doctor will suggest an X-ray. 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. It is, as we say, in tangent with the dens and tectoral ventrally alone. When I reviewed both of these patients imaging and cases, the only findings were slightly low CXAs and a Grabb-Oakes around 9mm. 2.

Dissection of the vertebral and carotid arteries is fairly rare and can be excluded through a doppler ultrasound or CT angiogram. Request an appointment or second opinion, refer a patient, find a doctor or view test results with MGfC's secure online services. A review of the diagnosis and treatment of atlantoaxial dislocations. All patients were treated with atlantoaxial plate and screw fixation using techniques described in 1994 and 2004. Atlas screws are generally placed in the lateral masses. The patient should demonstrate some brainstem symptoms, and may develop quadriparesis if the compression is sufficiently hard and constant. Because it doesnt work most of the time, and doesnt cause any lasting results. I recommend doing this with a neuro-ophthalmologist, not a general ophthalmologist or opticician, as the findings are often missed. This may cause the patient to become afraid and to google their symptoms, which in and by itself is reasonable enough. See my other articles or YouTube videos for howtos. 1977;59 (1): 37-44. Does thoracic outlet syndrome cause cerebrovascular hyperperfusion? Treatment, depending on the neurological symptoms and related pain, may be surgery. 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. 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. Specialist imaging research to help diagnosis. The patient will hinge back at their neck while simultaneously flexing the cranium. And, of course, to determine whether or not the findings actually correlate with the patients symptoms and clinical exam. 2012). KL TRENING & REHAB Burry HC, Tweed JM, Robinson RG, Howes R. Lateral subluxation of the atlanto-axial joint in rheumatoid arthritis. I prefer to compare mid-jugular to the highest pressure found, usually in the torcula or SSS. 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. Stay put for 30-60 seconds, look for worsening of symptoms while in the test. We'll assume you're ok with this, but you can opt-out if you wish. 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. Now, it is true that specialty diagnoses can be missed by local generalists. At Dr Gilete we are experts in Ehlers Danlos surgery, craniocervical instability EDS,neuro and spine disorders related to EDS and whiplash. 2015. 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 (! Neuronavigation assistance guides us all through the surgery, thus it diminishes (though it does not eliminate) the risks while placing the screws for the fusion. Yang SY, Boniello AJ, Poorman CE, Chang AL, Wang S, Passias PG. That is why they are much less affected by actual neck position than legitimate CCI AAI patients are, and certainly do not become symptom free in neutral positions. Magnetic resonance imaging assessment of the alar ligaments in whiplash injuries: a case-control study. Patient resources for the Down Syndrome Program. 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. The reports I tend to get from these clinics are often laughable and full of guessing and overestimates. I will update the article when I am back home in Colombia in the beginning of August. I dont recommend MRA. Neurologic signs of a cranial cervical myelopathy typically present at a young age and can range from cervical pain (hyperesthesia) to paralysis. Both tests should evaluate the movements of the occipitoatlantoid and atlantoaxial joints. Int J Spine Surg. The joint between the upper Journal of Neuro-Ophthalmology 2013;33:330337doi: 10.1097/WNO.0b013e318299c292, Alkhotani A. Cerebrospinal Fluid Rhinorrhea Secondary to Idiopathic Intracranial Hypertension. 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). The term AAI can also be used in cases of transverse ligament rupture, in which the odontoid process (the axis of the C2) may, especially if there is also damage to the tectorial membrane, dislocate dorsally and compress the brainstem. 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. 1. PMID: 32623537; PMCID: PMC8121728. The joint between the upper spine and base of the skull is called the atlanto-axial joint. 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. Because this article is, in essence, just another opinion piece, let us then focus on logical reasoning and objective arguments. 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 The atlanto-axial (AA) joint is the joint between the first (atlas) and second (axis) vertebrae (bones) in the neck. Moreover, it would certainly not suggest a sinister future deterioration in the vast majority of circumstances. Compression of the glossopharyngeal nerve will frequently cause pharyngeal pain (back of the throat pain) whereas vagal compression may lead to dry coughing, lump in the throat feeling, ear itching and various strange things when unilateral, but has been associated with more problematic issues when bilateral such as gastroparesis (Waldock et al. If a gliding is causing it (it is usually a glide or, a glide combined with mild rotation), no manipulation can fix it. Necessary cookies are absolutely essential for the website to function properly. 1927;11(1):155157. Let us look closer at these clinical entities and their associated symptoms, imaging findings, and, importantly, clinical triggers. Uniondale, NY Location HSS Long Island The Omni. medullary) symptoms when looking down, and will tend to improve when pulling the head up and back. You can also get these images done to get peace of mind if you do not have strong neurological sequelae related to the popping, but beware that many of these specialist clinics diagnose AAI CCI no matter what your imaging looks like, and therefore I generally recommend working with larger hospitals. Surgery is often challenging because of the shape of the C1 and C2 bones, and because the vertebral arteriespass in and around these two bones on the way to the brain. Bow hunters syndrome revisited: 2 new cases and literature review of 124 cases. to analyze our web traffic. It is possible to do it with extension and rotation, etc., but it is usually not necessary. Evaluation of the Cause of Internal Jugular Vein Obstruction on Head and Neck Contrast Enhanced 3D MR Angiography Using Contrast Enhanced Computed Tomography. and craniovenous outflow obstruction) will frequently cause severe fatigue, migraine, headache, dizziness, tinnitus, pain in the upper neck/back of the head (this is hypertensive migraine, not atlas pain Larsen et al 2020), POTS, memory loss, cognitive decline or fluctuating cognitive ability, syncopal event, seizures, and even, sometimes, hemi or paraparesis and other stroke-like symptoms. Surgical reduction and fixation would be the only appropriate treatment. If you or your veterinarian is concerned that your It will rarely cause frank luxation, however where the facets dislocate and lock laterally. If the symptoms happen along with aggressive neurological symptoms, however, or if your neck locks up in rotary fixation, greater concern could be applicable. Styloidogenic jugular venous compression syndrome: diagnosis and treatment: case report. The triggers would be especially relevant, seeing as various symptoms can heavily overlap between hundreds if not thousands of diagnoses. Search for condition information or for a specific treatment program. The utmost majority of these patients have have normal supine imaging, and many of them also normal or nearly normal upright imaging. Anaesth pain intensive care 2020;24(1)69-86. Rather, she would feel awful in general and felt worsening with stress and arm- & shoulder loading, and being upright vs. lying down. En este folleto, aprender sobre la IAA y cmo afecta a las personas con sndrome de Down. 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. Anesthesia, Critical Care & Pain Medicine, Billing, Insurance & Financial Assistance, Inestabilidad Atlantoaxoidea: (IAA): Lo Que Necesita Saber, Change in the way your son/daughter walks, Pain, numbness or tingling in the neck, shoulder, arms or legs, Loss of bladder control (having accidents). And, fair enough, I do not expect blind trust nor compliance. 2008). Although the complete differentiation between this and CCI or even occipital neuralgia is something that is complicated and must be done on individual basis after examination, we can, in essence, say that suboccipital pain that worsen with shoulder loading tends to be TOS or occipital neuralgia, whereas suboccipital symptoms that induce when lying down or being upright regardless of neck position tends to be TOS CVH. It is mandatory to procure user consent prior to running these cookies on your website. I hope that, by now, the reader has understood the importance that clinical measurements, actual pathology and clinical triggers should go hand in hand. #11760. In BI, the compression tends to be constant. 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. English. 2019 Oct;130:129-132. doi: 10.1016/j.wneu.2019.06.100. 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). It means that the instability is, or will probably, shortly, become bad enough to carry the potential to damage nerves or blood vessels. The most commonly used measures in the radiological evaluation of craniocervical instability and atlantoaxial instability are CXA, Grabb, BDI, BAI, ADI. 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. Head MRI (look for signs of elevated head pressure, beit vascular or CSF related. 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. We are committed to providing expert caresafely and effectively. to get a better impression of its actual thickness. Another diagnostic method used is cervical cineradiology, which records joint(s) movement of the entire occipitocervical, atlantoaxial and subaxial joint system. 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. Donald Corenman, MD, DC. 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. Call 314-362-3577 for Patient Appointments. 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. 1978 Dec;37(6):525-8. doi: 10.1136/ard.37.6.525. 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 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. Fundus exam (must be properly zoomed, must be exported in high digital quality and resolution). Dysautonomia when standing up is often related to craniovascular problems, whereas difficulty holding the head up suggests mumscular damage. Please understand that no matter how bad you feel, pursuing the wrong diagnosis will not help. My experience is that most of these patients suffer from craniovascular pathologies, not CCI and AAI. This is Bow hunters syndrome, and may be caused by legitimate atlantoaxial instability. 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. 10 things you should know about Cervical Disc Replacement. Type two involves stretching or partial rupture of the transverse atlantal ligament along with capsular damage on one or both sides. But this is rarely the case in my experience. The atlantoaxial segment consists of the atlas (C1) and axis (C2) and forms a complex transitional structure bridging the occiput and cervical spine. 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. 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. Diagnostic imaging: Spine, 3rd edition. Brainstem compression, when symptomatic, will usually cause quadriparesis along with phrenic nerve palsy. 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. Case Rep Neurol 2019;11:295298, Waldock WJ, Higgins NJ, Axon P. A case report of gastroparesis resolved by styloidectomy. 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.
