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. How is possible for them to have results when there is no symptomatic AAI/CCI? The success rate of this surgery is 80% or greater; however, there are many potential complications and a mortality rate of 5-10%. 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. 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. 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). 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. 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. 1-Craniocervical instability, levels C0-C1 (Occipital-atlas). PMID: 18708935. We moved on to perform the Valsalva maneuver (a pressure test), the Queckenstedts test (manual venous compression test), and the cervical retraction test (TOS CVH), in which the first and third tests were positive, reproducing severe head pressure, dizziness, presyncope and profound fatigue. Dr. Gilete in Spain, although I often disagree with his diagnoses, tends to order beautiful dynamic CT scans and also good craniovascular scans. 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! Because it doesnt work most of the time, and doesnt cause any lasting results. Symptoms of VBI develop rapidly in patients with legitimate and adequate degrees of vertebral artery compression when placed in the triggering position. If you have an atlanto-dens interval (ADI) of 5mm or greater, you have instability by definition. At Dr Gilete we are experts in Ehlers Danlos surgery, craniocervical instability EDS,neuro and spine disorders related to EDS and whiplash. In the Axis, pedicle screws are usually the first choice although, depending on the patients anatomy, placement of isthmic screws may be considered. 1. 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. Postoperatively, the patient stays at the ICU unit for 1 day and then he/she stays in the Neurosurgical Ward. to analyze our web traffic. Traumatic ligamentous ruptures or gradual deterioration of joint stability may cause basilar invagination, which is a degenerative process causing the odontoid process to graduall migrate into the head via the foramen magnum. Fundus exam (must be properly zoomed, must be exported in high digital quality and resolution). Atlas and axis screws are joined in each side by lateral bars that are unifying the instrumented fusion system. Moreover, genuine cases of brainstem compression causes paralysis and other upper motor neuron signs, and will present with syringobulbia or compressive bulbopathy. Last Update [site_last_modified date_format=Y-m-d H:i:s]. BDI, ie. Exam for bow hunters syndrome is done dynamically, but thats aother exam. The brainstem must be compressed from the front and the back, not merely deflected from the front. 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 critical view on the overdiagnosis of AAI/CCI. AAI is less common in adults with Down syndrome. 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. 1927;11(1):155157. Both positional (ie., upright. The personalized evaluation of each case is always convenient since it is very important that abnormalities of the vertebral artery anatomy are ruled out as well as the possible anatomical differences regarding the layout and dimensions of the vertebral pedicles, lateral masses and other bone elements. Articles Necessary cookies are absolutely essential for the website to function properly. The symptoms will completely resolve when returning to neutral position; usually even a few degrees reduction is enough to normalize flow. 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. Dr. Vicen Gilete, MD, Neurosurgeon & Spine Surgeon. 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. 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). Ultimately, the reader must discern for themselves. In other words, the vertical distance between the head and the spine. My experience has been that these approaches do not work, and certainly do not cause long term results. 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). 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 will be stored in your browser only with your consent. And, fair enough, I do not expect blind trust nor compliance. I diagnosed her with mild (benign) atlantoaxial instability and TOS CVH. This, usually due to trauma, but can also occur gradually due to certain autoimmune disorders such as rheumatoid arthritis, gross congenital hypermobility (such as Ehler Danlos syndrome or Marfan syndrome), or certain congenital syndromes such as Downs syndrome (Yang et al. Atlantoaxial subluxation frequently occurs in ligamentous and articular hypermobility syndromes such as Ehler Danlos syndrome. 2019) have documented numerous symptomatic cases of jugular vein stenosis at the craniovertebral junction. In 18 patients, dynamic images showed vertical, mobile and at-least partially reducible atlantoaxial dislocation. Eur J Pediatr. Bow hunters syndrome revisited: 2 new cases and literature review of 124 cases. In patients with Ehler Danlos syndrome, instability is present frequently in several segments, generally C0-C1-C2 (from occipital to axis). I hope that, by now, the reader has understood the importance that clinical measurements, actual pathology and clinical triggers should go hand in hand. Advanced Surgical Neuro-oncology Fellowship, Complex and Minimally Invasive Spine Deformity Fellowship, Endovascular Surgical Neuroradiology Fellowship, Neurosurgical Spine Innovation Fellowship, Neurosurgical Peripheral Nerve and Spine Fellowship. Burry et al (1978) documented a rare case of lateral luxation in a patient with rheumatoid arthritis, in which the supporting facet had eroded away. Copyright 2007-2023. This can result in AAI where the bones are less stable and can damage the spinal cord. 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 exam should be done lying down, without a neck pillow. collected, please refer to our Privacy Policy. 1963;13(5):386396. 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). The ligaments holding the bones together can also be injured in trauma, or weakened in certain inflammatory conditions such as rheumatoid arthritis or Downsyndrome. Radiographics 2000;20:S237-50. 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. 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. The success rate of this surgery is 80% or greater; however, there are many potential complications and a mortality rate of 5-10%. Global Spine J. 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. Instability in the hip can result in dislocation, ligament tears, muscle damage and wear of the joint. 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. 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. This is what I said from the beginning; AAI is not the cause of these symptoms, the exam and triggers do not fit. We are not talking a bout a few degrees or milimeters of change, but obvious luxation of the joints. The ligaments involved are the transverse, alar and capsular ligaments. Necessary cookies are absolutely essential for the website to function properly. This website uses cookies to improve your experience while you navigate through the website. 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. 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 (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. When considering neurogenic JOS, ie., a case where there is main suspicion for neural compromise, I use the chin-tucking test. 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. 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. 2011 Apr;15(1):41-47. This category only includes cookies that ensures basic functionalities and security features of the website. 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). Second of all, if there is suggested ADI widening, but a high quality supine MRI with low slice thickness ascertains patency of the majority of the fibers of the TAL, the likelihood of actual complete rupture and future brainstem injury is extremely low. 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. 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). Either way, if positive, move on to confirm narrowing of the jugular passage between the styloid process and C1 transverse process on a CT scan. Yang SY, Boniello AJ, Poorman CE, Chang AL, Wang S, Passias PG. Atlanto-axial instability (AAI) is a condition that affects the bones in the upper spine or neck under the base of the skull. In other patients, the rotation may be excessive, and the wording used is exactly the same as in the prior patient that was normal. Remember that the main dangers of atlantoaxial hypermobility are 1. facetal luxation, and 2., risk for rotational injury to the vertebral artery. This means routine X-rays are not helpful. Upright cervical MRI in flexion, extension and maximal bi-directional rotation. To compress the brainstem it must be compressed from both sides, both infront and behind. If the X-ray results are abnormal (different than usual), the doctor will order another imaging test, like a computed tomography (CT) scan or magnetic resonance imaging (MRI) test. Anaesth Pain & Intensive Care 2018;22(2):238-242. 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. 2012 Mar;70(3):E795-9. Atlantoaxial and craniocervical instability are both real and potentially sinister diagnoses that require treatment. 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. 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. 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. Safe Care CommitmentGet the latest news on COVID-19, the vaccine and care at Mass General.Learn more. Org. 333 Earle Ovington Blvd, Suite 106. Diagnostic markers for occult craniovascular congestion. Does it matter whether these are done laying or sitting down? The doctor will tell you which sports and activities are safe for your son/daughter. 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. Please understand that no matter how bad you feel, pursuing the wrong diagnosis will not help. Would this mean that upper cervical chiropractors (orthogonal, blair technique, gonstead, etc.) Another patient was told by a well-known pain physician in the US that she had brainstem compression and required several expensive prolotherapy procedures. Thus, I recommend the following studies for craniovenous hypertension and TOS CVH: Craniovasculo-hypertensive disorders (mainly IIH, TOS CVH (!) Dr. Nic Gay and Dr. Masi Reynolds specialize in getting to the root cause of the problem In circumstances of gross trauma, the ligamentous damage may be so severe that the entire vertebrae luxate (dislocate) from normal position. Rev. Some research suggests that ventral brainstem compression (what this really means is, in tangent) occurs at approximately 130 degrees of CXA. 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. About If the symptoms happen along with aggressive neurological symptoms, however, or if your neck locks up in rotary fixation, greater concern could be applicable. It mainly consists of the posterior fusion of the affected vertebrae, in this case, the atlas (C1) and the axis (C2). 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. 14 Postoperative care advices following cervical disc herniation surgery, 4 Predictive factors of the results in Cervical Herniated Disc surgery. Dysautonomia when standing up is often related to craniovascular problems, whereas difficulty holding the head up suggests mumscular damage. The patient should demonstrate some brainstem symptoms, and may develop quadriparesis if the compression is sufficiently hard and constant. If it is, however then flexion/extension and rotational imaging to exclude positional facetal luxation is warranted. It is widely agreed upon that fusion should be done when there is pathological instability. Typically, complete membraneous ruptures of the CVJ may cause dislocation between the head and neck, resulting in positional dissociation between the the two. This, with or without accompanied neurological symptoms, be it vascular or neurological. Because this article is, in essence, just another opinion piece, let us then focus on logical reasoning and objective arguments. to get a better impression of its actual thickness. Then the patient can make an informed decision about whether or not they want to invest in experimental therapy. Most dogs with AA instability will develop clinical signs within the first 2 years of life, often after a seemingly mild traumatic event. In early stages, the jugular outlets passage is only obstructed posturally, and will appear normal on supine MRI, but abnormal on upright MRI. I, personally, although I created my own manipulation protocol for this problem ALMOST NEVER use it. Spine (Phila Pa 1976). (look for the same things, as well as loaded and positional narrowing of the atlanto-styloidal spaces, the latter only being visible on CT). Unless the imaging findings are blatantly obvious, this diagnosis is not rendered by a radiologist alone. Apr 2, 2022 Any experience of Atlantoaxial instability? En este folleto, aprender sobre la IAA y cmo afecta a las personas con sndrome de Down. The mission of FORM Ortho is to be the preferred provider of orthopedic care and occupational health amongst our community, case managers and primary care physicians. In BI, the compression tends to be constant. 1978 Dec;37(6):525-8. doi: 10.1136/ard.37.6.525. Basil R. Besh, M.D. PMID: 32623537; PMCID: PMC8121728. Craniocervical Instability (CCI), also known as the Syndrome of Occipitoatlantialaxial Hypermobility. This is a major component in the workup for TOS CVH). In less severe cases, physical therapy can also help. The natural anatomic C1-C2 movement is basically rotation and approximately implies 50% of necks total rotation movement. 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. In most cases it is convenient to put bone graft, usually autologous, taken from the iliac crest or the patients own rib. Li M, Gao X, Rajah GB, Liang J, Chen J, Yan F, et al. Explore fellowships, residencies, internships and other educational opportunities. 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). I am not saying that this applies to every DMX center nor that DMX in and by itself is never useful, but due to the overwhelming lack of competence that tends to come with these studies, I dont recommend them unless unless you have obviously abnormal imaging otherwise and want to look for occult fractures or similar sinister and stubbornly identified problem. None of these tests would be able to reproduce her symptoms if they were stemming from AAI or CCI. 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. In addition to that we would start treatment for thoracic outlet syndrome. The most commonly used measures in the radiological evaluation of craniocervical instability and atlantoaxial instability are CXA, Grabb, BDI, BAI, ADI. PMID: 24475346; PMCID: PMC3899735. Get the latest news on COVID-19, the vaccine and care at Mass General. And if yes, do they completely normalize when resuming neutral position? As always, it is important to do a clinical radiological correlation to make an accurate assessment. 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. The patient had headache, dizziness, fatigue, pain in the arms and chest and often felt difficulty breathing. 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. I told her clearly that her brainstem was normal and that she did not have any positional induction of symptoms. 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. JRSM Short Rep. 2013 Nov 21;4(12):2042533313507920. doi: 10.1177/2042533313507920. Fielding JW, Hawkins RJ. This madness must stop. In the cases where it is not possible to obtain autologous bone graft, heterologous graft (artificial bone) may also be used. ADI laxity is mainly caused by head and neck trauma, so as long as you avoid future collisions, it will probably not deteriorate. Testimonials Merely feeling worse when standing up, even if indeed feeling awful, is not a strong indicator of AAI CCI As mentioned above, it is the influence of cervical positioning.

This website uses cookies to improve your experience while you navigate through the website. 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. 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. A positive test would be interpreted by unbearable head pressure, lightheadedness, worsening of headache, etc., within about 20-30 seconds. What Is Atlanto-Axial Instability (AAI)? 2. Uniondale, NY Location HSS Long Island The Omni. Atlas screws are generally placed in the lateral masses. A review of the diagnosis and treatment of atlantoaxial dislocations. Signs of ligamentous damage. The report claimed that there were signs of ligamentous rupture and bidirectional subluxation upon rotation in the atlantoaxial joints. This, again, prompted the more than 1000 euro consultation with the upright imaging center in a large european country. Both neurophysiological monitoring and neuronavigation guidance are safety measures for the patient. I recommend sticking to clinics that have good reputations and good imaging protocols. 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. 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. 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. Just like the CXA, this measurement is supposed to aid with objective measurements rather than just eyeballing the images, and writing down your impressions. For occipial neuralgia, an ultrasound guided nerve block will cure these symptoms for three hours and thus confirm the diagnosis. https://doi.org/10.13104/jksmrm.2011.15.1.41. 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.
