Prior to surgery we perform a surgical planning of the intraoperative neuronavigation to confirm the trajectories of screws and special anatomical dispositions of structures. And, she still had the same symptoms! I have seen countless reports from DMX centers where the patient, despite having normal or virtually normal conventional imaging, the patient is delivered reports of laughable quality, typically deeming the whole neck as unstable, despite the images being virtually normal. Knattlia 2, 3038 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. Albeit still a surgically treated problem. 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. Followup with a dynamic CT, supine MRI or similar to confirm potentially equivocal findings is warranted. The success rate of this surgery is 80% or greater; however, there are many potential complications and a mortality rate of 5-10%. We offer diagnostic and treatment options for common and complex medical conditions. 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. 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. Look for upright compression of the IJVs), Dynamic CT also works well, but has much more radiation. In many circumstances, conservative treatment (Larsen 2018, atlas joint article as linked earlier) is appropriate. 14 Postoperative care advices following cervical disc herniation surgery, 4 Predictive factors of the results in Cervical Herniated Disc surgery. Last Update [site_last_modified date_format=Y-m-d H:i:s]. 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. to analyze our web traffic. Another common belief is that this mild deflection stretches the brainstem and somehow causes damage. Rather, it must be compressed by the dens ventrally, and flaval ligament and lamina posteriorly. 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. 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. This pain tends to get worse with stress and with high heart rates, and are often also worse in the morning after lying down. The utmost majority of these patients have have normal supine imaging, and many of them also normal or nearly normal upright imaging. The patient should demonstrate some brainstem symptoms, and may develop quadriparesis if the compression is sufficiently hard and constant. You also have the option to opt-out of these cookies. 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. In such cases I tell my patients that, yes, you do have mild AAI, but it is not causing your symptoms. Atlantoaxial instability (AAI) is a potential complication of all forms of EDS. For TOS CVH the patient will generally feel better when stress is reduced along with taking beta blockers (confer with your doctor). Posture is done for the rest of your life. Look for signs of retinal hypertension (subtle copper wiring, AV nicking, tortuosity of the arterioles, generalized vasospasm or papilledema. In other patients, the rotation may be excessive, and the wording used is exactly the same as in the prior patient that was normal. Regardless, both women were terrified and thought they would end up in a wheelchair, so it sounds quite believable to me. 2000). Exam for bow hunters syndrome is done dynamically, but thats aother exam. Kjetil Larsen is a Researcher and a injury rehabilitation specialist, and is the owner of MSK Neurology. 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. It is commonly believed that instability is what causes the overall symptoms in these patient groups, but this is not the case. Brainstem compression, when symptomatic, will usually cause quadriparesis along with phrenic nerve palsy. This is not dangerous, but can cause some popping, restriction in movement, and some pain upon articulation. What cervical artificial disc should I choose? Diagnostic imaging: Spine, 3rd edition. If your child has symptoms of AAI, the doctor will suggest an X-ray. For patients with post-traumatic ligamentous injuries where measurements are still within normal limits, obvious segmental effusion should be seen despite otherwise normal anatomical positioning. Pain medications and anti-inflammatories are typically also prescribed. Our surgeons can discuss with you the various treatment options for your specific condition. Required fields are marked *. Neurosurgery. If a gliding is causing it (it is usually a glide or, a glide combined with mild rotation), no manipulation can fix it. Both neurophysiological monitoring and neuronavigation guidance are safety measures for the patient. If someone has an ADI of 4.5mm, can this be treated via physical therapy, or is it too much instability? Otolaryngology Case Reports Volume 16, September 2020, 100201, Larsen K, Galluccio FC, Chand SK. I see massive amounts of patients with alleged AAI who have normal atlantoaxial facetal overlap, and of course, also lacking clinical correlation. Call 314-362-3577forPatient Appointments. PMID: 25210334; PMCID: PMC4158632. 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. 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). 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. 2008). 333 Earle Ovington Blvd, Suite 106. Copyright Dr Gilete Neurosurgery & Spine Surgery. Moreover, genuine cases of brainstem compression causes paralysis and other upper motor neuron signs, and will present with syringobulbia or compressive bulbopathy. 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. 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. It means that the instability is, or will probably, shortly, become bad enough to carry the potential to damage nerves or blood vessels. Post count: 8446. 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. 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. 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. 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. If unavailable, a CT angiogram can be used, but is less sensitive. 2019 Feb 22;13(1):79-83. doi: 10.14444/6010. We use cookies and other tools to enhance your experience on our website and Strong evidence of clinical correlation must be present from a clinician that is familiar with the signs and triggers in upper cervical instability-cases. A lof patients have clicking and clunking in the neck along with severe suboccipital pain. The report claimed that there were signs of ligamentous rupture and bidirectional subluxation upon rotation in the atlantoaxial joints. 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. Additionally, spinal instability in the form of spondylolisthesis 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. 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. It is possible to do it with extension and rotation, etc., but it is usually not necessary. 1963;13(5):386396. This is a major component in the workup for TOS CVH). E7. This would depend on whether or not the compression of the brainstem is constant, which again would depend on several factors. Not sure what you mean here. 2020). Testimonials 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. Atlantoaxial fixation: overview of all techniques. 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. I prefer to compare mid-jugular to the highest pressure found, usually in the torcula or SSS. 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. More information about surgical treatment. A critical view on the overdiagnosis of AAI/CCI. 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. I hope that, by now, the reader has understood the importance that clinical measurements, actual pathology and clinical triggers should go hand in hand. Now, the I was told is clearly second-hand information, and I cannot guarantee its accuracy.

We also use third-party cookies that help us analyze and understand how you use this website. En este folleto, aprender sobre la IAA y cmo afecta a las personas con sndrome de Down. Facetal locking with rigid torticollis (Cock Robin syndrome) or similar, in cases where there is no neurological compromise, is less dangerous. Symptoms of brainstem compression are respiratory crisis and quadriplegia, but can also manifest more diffusely. Both measurements tend to worsen with neck extension. 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. Last Update [site_last_modified date_format=Y-m-d H:i:s]. It will rarely cause frank luxation, however where the facets dislocate and lock laterally. 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. 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. 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. It is crucial to understand that the general minor instabilities involved in AAI and CCI are not the cause of symptoms. 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! Signs of ligamentous damage. I recommend sticking to clinics that have good reputations and good imaging protocols. Dr. Christopher Williams | 07/09/2020. Neurology. 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. Let us help you navigate your in-person or virtual visit to Mass General. Identifying The Signs Of Cervical Instability. J NS 2015, V8 issue 4. Second, because it is such a controversial topic that lacks medical consensus, poor understanding of the actual mechanism of pathology leads to misunderstandings. Dr. Vicen Gilete, MD, Neurosurgeon & Spine Surgeon. In severe cases, I recommend postural corrections (appropriate, not generic) along with styloidectomy and transversectomy. There can be, and are indeed many more potential explanations for these symptoms than just AAI and CCI. 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 In my experience, we would expect to see at least 20mmHg maximum venous pressures. What Is Atlanto-Axial Instability (AAI)? 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! 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. Now, it is true that specialty diagnoses can be missed by local generalists. Dr. Nic Gay and Dr. Masi Reynolds specialize in getting to the root cause of the problem In such a case, to avoid foreseeable medullary damage, one may reasonably opt for fusion as preventative surgery, because the medulla, once damaged, does not always recovery after surgery. The findings may be quite subtle and are easy to miss outside of dynamic exams. 9/2017. Diagnostic markers for occult craniovascular congestion. How is possible for them to have results when there is no symptomatic AAI/CCI? First of all, studies have shown that FLAIR hyperintensities (suggestive of ligamentous partial rupture or damage) have been found in a lot of asymptomatic patients (Myran et al. Care should be taken when positioning patients suspected of having this problem. The patient will hinge back at their neck while simultaneously flexing the cranium. The atlantoaxial subluxation can occur isolated or can be found in cases in which there is also craniocervical instability. When I reviewed both of these patients imaging and cases, the only findings were slightly low CXAs and a Grabb-Oakes around 9mm. This site complies with the HONcode standard for trustworthy health information: verify here. The diagnosis can be made by means of an Upright MRI (magnetic Resonance Imaging) or with a cervical CT scan with 3D reconstruction. 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. Atlantoaxial instability and craniocervical instability are spinal manifestations directly due to ligament laxity. 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. 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. The joint between the upper spine and base of the skull is called the atlanto-axial joint. 1927;11(1):155157. collected, please refer to our Privacy Policy. doi: 10.1227/NEU.0b013e3182333859. Type three involves anterior subluxation of the entire atlas due to combined full rupture of the TAL and partial rupture of the capsules and other structures. Fielding JW, Hawkins RJ. The BDI indicates vertical-, and the BAI horizontal structural integrity. The CXA was 138 degrees and the Grabb-Oakes measurement was 8,3mm. But a patient who just feels bad (even if they feel very bad), and especially if they do not have positional triggers and their imaging does also not demonstrate constant brainstem or otherwise vascular compromise that fits with the symptoms, then diagnosing such a patient with CCI or AAI and claiming its presence as the culprit of their symptoms, is madness. Treatment depends on your son/daughters symptoms. The problem, in the patients eyes, may be a lacking reasonable counter-argument and counter-diagnosis that would explain his or her symptoms, which then prompts the patient to seek out alternative health care. Both positional (ie., upright. Clunking, clicking and pain in the upper neck. 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. One or 2 out of every 100 children with Down syndrome have symptoms of AAI, but doctors do not know the exact number yet. Get the latest news, explore events and connect with Mass General. In severe (very bad) cases, your son/daughter might need neck surgery. She had been out from work for one year at the point of consultation, but her doctors could not find anything wrong with her. What does this mean? Some have proposed 2mm of translational difference, but this is completely unreliable in my opinion and exprience. We can still treat it preventatively, but it wont resolve the symptoms. 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. When Atlantoaxial instability occurs along with craniocervical instability, also known as occipitocervical instability (ie instability present also between skull and first cervical vertebra or Atlas), then fusion should consist of adding a fixation to the cranial bone through occipital or condylar screws which would give us as a whole C0 -C1-C2 posterior fusion. I am not saying it is easy. The other side of the AAI/CCI coin is the risk for facetal luxation; a less sinister-, but still a problem that warrants surgical treatment. Curr Neurovasc Res. There are no exercises that can help an instability like that. 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. 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. 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). Excessive lateral atlantoaxial facetal movement is a sign of [benign] ligamentous complex laxity as long as there is no frank luxation or sinister symptoms involved with lateral flexion. 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. Neurol India. 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. This website uses cookies to improve your experience. 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. This category only includes cookies that ensures basic functionalities and security features of the website. If this X-ray is repeated, the AAI might go away. TOS is often considered a mere upper limb nerve pathology, but this is not the case. This iatrogenic practice must come to an end. In these cases, the direct signs and indirect signs of atlantoaxial subluxation must be objectified. 2009), but this is extremely rare. Seemingly unrelated, Higgins et al (2013) and others (Dashti et al 2012, Li et al. The atlanto-axial (AA) joint is the joint between the first (atlas) and second (axis) vertebrae (bones) in the neck. Bow hunters syndrome revisited: 2 new cases and literature review of 124 cases. 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. I believe that most of these practitioners mean well. To schedule an appointment, call one of the offices, or book an appointment online. J Bone Joint Surg Am. Atlanto-axial instability (AAI) is a condition that affects the bones in the upper spine or neck under the base of the skull. 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. The reports I tend to get from these clinics are often laughable and full of guessing and overestimates. Would need a flexion extension MRI and correlate to the patients symptoms. Type D would generally involve a dens fracture as the atlas migrates posteriorly, along with facetal luxation and capsular rupture. Some top offenders may suggest full craniocervical fusion, ie. 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 surgeon may claim that because there is translational differences, meaning that the interval increases with movement, this is evidence of sinister CCI or AAI regardless of the measurement still being within normal limits. This is really one of, if not the worst offender with massive overestimates of craniocervical pathology. Moreover, tractioning the neck of these vulnerable patients can often cause undesirable effects. In less severe cases, physical therapy can also help. 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). I dont recommend MRA. That said, yes, it is my opinion that the treatment is nonsense. 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. 2014 Feb;11(1):75-82. ncbi.nlm.nih.gov/pubmed/24321024, Higgins JN et al. 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 (! This category only includes cookies that ensures basic functionalities and security features of the website. 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. In most circumstances, even if there is poor overlap but no evidence of frank facetal luxations (clinical history or with provocation), then conservative therapy can usually prevail in management. 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. Another scenario could be that the patient has been diagnosed with atlantoaxial rotary subluxations, as little facetal overlap, lets say, 15%, is seen upon bidirectional rotation. If there are no symptoms, then what reuslts are you talking about? 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. are generally useless in most cases? In people with Down syndrome, the ligaments (connections between muscles) are lax or floppy. I, personally, although I created my own manipulation protocol for this problem ALMOST NEVER use it. Org. Knowing this it allows to anticipate any possible problems in the postoperative period. 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. If the measurements are within normal limits, the likelihood of dangerous sequelae are low, if not absent. Call us: 212.774.2837 Uniondale, NY Location HSS Long Island The Omni. Higgins N, Pickard J, Lever A. Lumbar puncture, chronic fatigue syndrome and idiopathic intracranial hypertension: a cross-sectional study. 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. I very often receive upright MRI reports where the rotation is completely normal, and the patient is still diagnosed with AAI. This is Bow hunters syndrome, and may be caused by legitimate atlantoaxial instability. To the best of my knowledge, I was the first person to document the notion that this was, in essence, a postural phenomenon that is induced due to poor posture over a long period of time (Larsen 2018). 2-Atlantoaxial instability, levels C1-C2 (atlas-axis). Another patient was told by a well-known pain physician in the US that she had brainstem compression and required several expensive prolotherapy procedures. This, seriously augmented by poor hinge neck postures (Larsen 2018). Thus we control the spinal cord and nerves (cranial and cervical) in order to avoid potential damages to these important structures. Commonly misunderstood and overemphasized measurements. 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. Neurologic signs of a cranial cervical myelopathy typically present at a young age and can range from cervical pain (hyperesthesia) to paralysis. The functional result of 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). Then, if there are not even sufficient findings for surgery, how can one possibly give such a fatal prognosis? 2021 Feb;180(2):441-447. doi: 10.1007/s00431-020-03836-9. Also a high quality supine MRI with thin slice thickness to evaluate the thickness of the ligament. Kjetil has also published several peer-reviewed studies on musculoskeletal and neurological topics. 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. Sometimes flexion-extension and rotational imaging is necessary. 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.
