Abbreviations: BDI: basion dens interval, CXA: clivo axial angle, BAI: basion-axial interval, ADI: Atlantoaxial interval. 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. DOI: https://doi.org/10.35975/apic.v24i1.1230. Bow hunters syndrome revisited: 2 new cases and literature review of 124 cases. Surgical options, sometimes including relevant-level fusion, may be warranted in these circumstances. Medical management entails strict cage rest and placing a neck brace (from in front of the ears to the mid-chest) to prevent the vertebrae of the neck from moving and causing more damage to the spinal cord. 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. A positive test would be interpreted by unbearable head pressure, lightheadedness, worsening of headache, etc., within about 20-30 seconds. Rather, it must be compressed by the dens ventrally, and flaval ligament and lamina posteriorly. This is one of the biggest offenders along with DMX and CXA, causing massive confusion, coercion, and misdiagnosis. The triggers would be especially relevant, seeing as various symptoms can heavily overlap between hundreds if not thousands of diagnoses. Why would you jump to the worst possible explanation, and especially when lacking apt evidence? I am not saying it is easy. 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. Ann Rheum Dis. Atlantoaxial subluxation frequently occurs in ligamentous and articular hypermobility syndromes such as Ehler Danlos syndrome. La inestabilidad atlantoaxoidea (IAA) es una enfermedad que afecta los huesos de la parte superior de la columna vertebral. 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). All conventional things like heart and lung problems, MS, cancer, infections etc. Magnetic resonance imaging assessment of the alar ligaments in whiplash injuries: a case-control study. 1. Another patient was told by a well-known pain physician in the US that she had brainstem compression and required several expensive prolotherapy procedures. Secondly, and perhaps more importantly, the extent of facetal overap must be measured. Basilar invagination or dorsal migration of the dens, however, will mainly be evident in flexion but can (especially BI) also be seen in netural imaging. Moreover, craniovascular disorders often fluctuate depending on whether or not the patient is upright or lying down (sometimes lying down is worse, sometimes standing up makes it worse), and do certainly not return to normal, symptom-free status when the neck is placed in neutral position. Most dogs with AA instability will develop clinical signs within the first 2 years of life, often after a seemingly mild traumatic event. 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. 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. 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. 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. Because this article is, in essence, just another opinion piece, let us then focus on logical reasoning and objective arguments. A patient with positional brainstem compression due to TAL rupture, for example, will develop neurological (ie. I have seen several patients misdiagnosed and become almost paralyzed by anxiety due to an increased Grabb-Oakes measurement where the dens is just barely in tangent with the brainstem, despite zero evidence of actual compression nor signal changes in the brainstem and with normal neurological examinations without any upper motor lesion signs! Moreover, genuine cases of brainstem compression causes paralysis and other upper motor neuron signs, and will present with syringobulbia or compressive bulbopathy. However, can we say the same if there is major guesswork involved in the rendering of the diagnosis? In addition to that we would start treatment for thoracic outlet syndrome. 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. The success rate of this surgery is 80% or greater; however, there are many potential complications and a mortality rate of 5-10%. If unavailable, a CT angiogram can be used, but is less sensitive. My experience is that most of these patients suffer from craniovascular pathologies, not CCI and AAI. If nicely timed, around 20 secs after infusion, beautiful visualization of both arteries and veins is permitted). Therefore, when I hear about patients being operated on with no other abnormality than a CXA of 140 degrees, my opinion is that this is reckless butchery. Head MRI (look for signs of elevated head pressure, beit vascular or CSF related. Does it matter whether these are done laying or sitting down? Rather, she would feel awful in general and felt worsening with stress and arm- & shoulder loading, and being upright vs. lying down. 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. Clunking, clicking and pain in the upper neck. A CTV is preferable, but a general neck CT will also do if you have sensitive kidneys and would like to avoid contrast infusion. As mentioned initially in this article, craniocervical instability is mainly associated with jugular outlet obstruction and basilar invagination, whereas atlantoaxial instability can cause posteriorization of the dens and brainstem compression, or rotational dysfunction resulting in either bow hunters syndrome, Cock Robin syndrome or other variants of segmental luxations. 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. And if yes, do they completely normalize when resuming neutral position? He also found that severe misalignment of these joints were often associated with Chiari malformation, basilar invagination, and various other pathologies. 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. 2014 Aug;4(3):197-210. doi: 10.1055/s-0034-1376371. ADI laxity is mainly caused by head and neck trauma, so as long as you avoid future collisions, it will probably not deteriorate. You also have the option to opt-out of these cookies. We also use third-party cookies that help us analyze and understand how you use this website. Learn about career opportunities, search for positions and apply for a job. Additionally, spinal instability in the form of spondylolisthesis The renowned scholar and neurosurgeon professor Atul Goel was the first person, to the best of my knowledge, to acknowledge and document the notion of horizontal misalignment of the craniocervical facet joints and that this would often be present despite a completely normal-looking mid-sagittal slice (where most craniovertebral junction measurements are done). It is not a substitute for medical advice and should not be used to treatment of any medical conditions. 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). Musa et al. You also have the option to opt-out of these cookies. 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 (! our TOS CVH paper (Larsen et al 2020). 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). For treatment of the facetal dysfunction I recommend postural correction for the head neck and shoulder blades, along with exercises for the trapezius, levator scapulae, suboccipital and deep neck flexor muscles. But opting out of some of these cookies may affect your browsing experience. 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. Some top offenders may suggest full craniocervical fusion, ie. 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). This is reasonable. 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. I have not receiving anything that comes close of what they produce. Powers ratio will be abnormal in cases of both BI and craniocervical dissociation (Ross & Moore, 2015). 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. In people with Down syndrome, the ligaments (connections between muscles) are lax or floppy. Knowing this it allows to anticipate any possible problems in the postoperative period. Training is done carefully twice per week. 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. 2011, Dashti et al. More commonly, however, a due to asymmetrical tearing of the covering ligaments, rotational subluxation or frank luxation is seen according to the Fielding & Hawking classifications (1977): Type 1, 2, 3 and 4, wherein types one and two are the most commonly encountered ones. This website uses cookies to improve your experience while you navigate through the website. The surgical treatment for Atlantoaxial instability, when it manifests alone without occipitocervical instability, it mainly consists of a This means routine X-rays are not helpful. Dissection of the vertebral and carotid arteries is fairly rare and can be excluded through a doppler ultrasound or CT angiogram. Whats interesting, regardless, is that one year after we had the first consultation she underwent another uMRI (due to lack of improvement of symptoms), which showed completely resolution of the atlantoaxial subluxations, which were now overlapping at about 30%; 300% improvement (remember: >20% is normal). The atlanto-axial (AA) joint is the joint between the first (atlas) and second (axis) vertebrae (bones) in the neck. J Craniovertebr Junction Spine. Information about the identification of CVJ fractures will not be applicable for patients with chronic workups and lacking imaging findings over a long period of time. With the increasing dependence on smartphones, computers, and other devices in our modern English +34 93 220 28 09 Espaol +34 93 198 34 24 You mention to test for craniovascular pathologies, we should get a Doppler examination of the carotid and cerebral arteries done, and a CT angiogram done. 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. Dr. Christopher Williams | 07/09/2020. 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. These cookies will be stored in your browser only with your consent. It is different from other joints in the vertebral https://doi.org/10.13104/jksmrm.2011.15.1.41. 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. Fielding JW, Hawkins RJ. Why do they have results tho when they correct the atlas/axis? And, fair enough, I do not expect blind trust nor compliance. 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. In severe (very bad) cases, your son/daughter might need neck surgery. This category only includes cookies that ensures basic functionalities and security features of the website. In patients with Ehler Danlos syndrome, instability is present frequently in several segments, generally C0-C1-C2 (from occipital to axis). 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. 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. I dont recommend MRA. Out of these, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. 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, Signs of ligamentous damage. What does this mean? Foramen magnum decompression or syrinx manipulation was not performed in any patient. 2019 Feb 22;13(1):79-83. doi: 10.14444/6010. DMX. This is not good medical practice. Often, by radiologist alone, based on sparsome imaging findings (eg., alar ligament T2 FLAIR hyperintensity or mild to moderate lateral facetal overhangs) and a lacking compatible clinical workup. Get the latest news on COVID-19, the vaccine and care at Mass General. Post count: 8446. 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. had been excluded by her primary care physicians and local hospital. To schedule an appointment, call one of the offices, or book an appointment online. A review of the diagnosis and treatment of atlantoaxial dislocations. The exam should be done lying down, without a neck pillow. to get a better impression of its actual thickness. What cervical artificial disc should I choose? It means that the instability is, or will probably, shortly, become bad enough to carry the potential to damage nerves or blood vessels. 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. 333 Earle Ovington Blvd, Suite 106. Patients with hyperrotation of the atlantoaxial joints can also develop Bow hunters syndrome (BHS). Atlantoaxial instability is a congenital neurologic condition predominantly affecting toy breed dogs. We'll assume you're ok with this, but you can opt-out if you wish. Just like the CXA, this measurement is supposed to aid with objective measurements rather than just eyeballing the images, and writing down your impressions. Upright MRI has very low quality and because of this, there is a lot of guesswork involved in its interpretation. But if there is lots of space for the medulla, such invasive surgery simply is not warranted. In dogs with atlantoaxial subluxation, instability of the atlantoaxial joint results from a loss of ligamentous support of the axis, often with concurrent aplasia, hypoplasia or dysplasia of the dens. 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. 2014 Aug;4(3):197-210. 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. Privacy policy, Do you really have atlantoaxial and craniocervical instability? Thus, the patients in the rotary subluxation group are expected to present with severe and sudden neck pain as well as rigidity to the extent of being unable to move the neck. Dr. Gilete in Spain, although I often disagree with his diagnoses, tends to order beautiful dynamic CT scans and also good craniovascular scans. The BDI indicates vertical-, and the BAI horizontal structural integrity. Now, the I was told is clearly second-hand information, and I cannot guarantee its accuracy. Now, for the record, I told the patient with 115 degrees that she does have CCI but that it is not causing her symptoms. Atlanto-axial rotatory fixation. Once in the Operating Room, surgery is performed under general anesthesia, with Neurophysiological monitoring (SSEP somatosensory evoked potentials), neuronavigation guidance and intraoperative fluoroscopy guidance. This is no longer true. The ligaments supporting these joints are quite strong, but if they become (look for the same things, as well as loaded and positional narrowing of the atlanto-styloidal spaces, the latter only being visible on CT). PMID: 749697; PMCID: PMC1000289. In other words, the vertical distance between the head and the spine. Treatment, depending on the neurological symptoms and related pain, may be surgery. Uniondale, NY 11553. Instability in the hip can result in dislocation, ligament tears, muscle damage and wear of the joint. The joint between the upper There are no exercises that can help an instability like that. Therefore before proposing surgery, the evaluation of each case must be done really carefully. Many of these patients who have been misdiagnosed with AAI or CCI may feel neck wobbliness, heaviheaded, neck weakness, and clicking or clunking in the neck upon movement, often along with upper neck pain. This is a major component in the workup for TOS CVH). Testimonials Search for condition information or for a specific treatment program. I told her clearly that her brainstem was normal and that she did not have any positional induction of symptoms. 2000). The instability present between these vertebrae can cause the vertebrae to shift and injure the spinal cord. 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. This, again, prompted the more than 1000 euro consultation with the upright imaging center in a large european country. Neurosurgery. The doctor will tell you which sports and activities are safe for your son/daughter. Some rare cases have also demonstrated rotary compression of the vertebral artery in the lower neck due to arthritis or disc bulges that fills up the transverse foraminae (Ujifuku et al. Upright cervical MRI in flexion, extension and maximal bi-directional rotation. 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. 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). 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. This is not dangerous, but can cause some popping, restriction in movement, and some pain upon articulation. Does thoracic outlet syndrome cause cerebrovascular hyperperfusion? Both tests should evaluate the movements of the occipitoatlantoid and atlantoaxial joints. 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. Clinical signs of such an injury include neck pain, weakness in all limbs, and potentially paralysis from the neck down and death. 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. 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. Higgins N, Pickard J, Lever A. Lumbar puncture, chronic fatigue syndrome and idiopathic intracranial hypertension: a cross-sectional study. 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. 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. Burry HC, Tweed JM, Robinson RG, Howes R. Lateral subluxation of the atlanto-axial joint in rheumatoid arthritis. Let us help you navigate your in-person or virtual visit to Mass General. How is one supposed to know, if no one knows what you have in the first place? Postoperative hospital stay is usually around 7 days. Imaging will prove brainstem compression on [flexion/extension] MRI, and an increased atlantodental interval on flexion/extension CT or x-ray. Copyright Dr Gilete Neurosurgery & Spine Surgery. This madness must stop. Due to the instability in the craniocervical junction deformation can occur to the brainstem, upper spinal cord, and cerebellum. It is important to understand that the size of the facets is what determines what degree of rotation would be excessive. Atlantoaxial instability (AAI) is the term for increased motion at the joint between the 1st and 2nd cervical vertebrae (the atlas and the axis). Gweon HM, Chung TS, Suh SH. Remember that the main dangers of atlantoaxial hypermobility are 1. facetal luxation, and 2., risk for rotational injury to the vertebral artery. The report claimed that there were signs of ligamentous rupture and bidirectional subluxation upon rotation in the atlantoaxial joints. In the cases where it is not possible to obtain autologous bone graft, heterologous graft (artificial bone) may also be used. Deliganis AV, Baxter AB, Hanson JA, et al. She had been out from work for one year at the point of consultation, but her doctors could not find anything wrong with her. 2009), but this is extremely rare. Atlantoaxial instability is an uncommon condition of dogs in which there is abnormal movement in the neck, between the atlas (first cervical vertebra) and axis (second vertebra). 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. This pain tends to get worse with stress and with high heart rates, and are often also worse in the morning after lying down. Diagnosis is often based on survey radiographs, alth Atlantoaxial Instability Look for upright compression of the IJVs), Dynamic CT also works well, but has much more radiation. Elsevier Publishing. Copyright Dr Gilete Neurosurgery & Spine Surgery. medullary) symptoms when looking down, and will tend to improve when pulling the head up and back. 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.

DOI: 10.3171/2015.1.FOCUS14791. It is imperative to understand that patients with dagerous craniovertebral junction injuries, although one may sometimes require a dynamic CT or x-ray to identify them, will have clear imaging findings combined with clear clinical triggers in the utmost majority of incidences. This would depend on whether or not the compression of the brainstem is constant, which again would depend on several factors. Thus we control the spinal cord and nerves (cranial and cervical) in order to avoid potential damages to these important structures. Sometimes, an X-ray shows AAI when there are no symptoms. 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. Strong evidence of clinical correlation must be present from a clinician that is familiar with the signs and triggers in upper cervical instability-cases.
