Gweon HM, Chung TS, Suh SH. 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. 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. DMX. 2019) have documented numerous symptomatic cases of jugular vein stenosis at the craniovertebral junction. None of these tests would be able to reproduce her symptoms if they were stemming from AAI or CCI. How is possible for them to have results when there is no symptomatic AAI/CCI? Search for condition information or for a specific treatment program. This site complies with the HONcode standard for trustworthy health information: verify here. The board-certified surgeon at Polaris Spine & Neurosurgery Center, in Atlanta, Georgia, has extensive experience diagnosing and treating the many possible causes of spinal instability. Copyright statement If the patients neck often completely locks up due to facetal luxations, then atlantoaxial fixation may certainly be a viable option for treatment, especially if conservative stabiization fails (capsular and alar ligamentous prolotherapy, postural corrections, strengthening of the suboccipital, longus capitis and levator scapulae muscles). Global Spine J. Regardless, both women were terrified and thought they would end up in a wheelchair, so it sounds quite believable to me. This conformation may be associated with thickening of the interarcuate ligament (atlantoaxial band), which has been interpreted as an indicator for instability in the atlantoaxial joint [79]. Org. Typically, complete membraneous ruptures of the CVJ may cause dislocation between the head and neck, resulting in positional dissociation between the the two. Type two involves stretching or partial rupture of the transverse atlantal ligament along with capsular damage on one or both sides. Furthermore, a claim of brainstem stretching and kinking with resultant medullary microdamage that somehow not responds negatively to being stretched in real-time, and also lacking upper motor neuron signs, is not a very realistic claim. 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. We are committed to providing expert caresafely and effectively. 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. Surgery to address problems in this area can be risky. 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. A lot of things that cause temporary results are just placebo. Most dogs with AA instability will develop clinical signs within the first 2 years of life, often after a seemingly mild traumatic event. 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. It is mandatory to procure user consent prior to running these cookies on your website. 1963). 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. I, personally, although I created my own manipulation protocol for this problem ALMOST NEVER use it. A 3D rendered CT scan should easily demonstrate the luxation in cases where the sagittal slices appear normal or close to normal, whereas cases of dens migration will also appear obviously abnormal in the sagittal planes of imaging. 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. Instability in the hip can result in dislocation, ligament tears, muscle damage and wear of the joint. Atlantoaxial subluxation frequently occurs in ligamentous and articular hypermobility syndromes such as Ehler Danlos syndrome. 10 things you should know about Cervical Disc Replacement. A review of the diagnosis and treatment of atlantoaxial dislocations. Conveniently, she was sent out to a colleague for very expensive nonsense therapy (again, regardless of lacking serious findings that would require surgery) and sent tens of thousands of euros on stemcell and prolotherapy procedures in a desperate attempt to avoid the inevitable wheelchair. Imaging will prove brainstem compression on [flexion/extension] MRI, and an increased atlantodental interval on flexion/extension CT or x-ray. This website uses cookies to improve your experience while you navigate through the website. 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. 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. I told her that, although I dont think theres any evidence to suggests that the AAI is causing your symptoms, we should still treat it to prevent the risk of future frank luxations of the joints. Neurol India. If the latter, could be JOS obstruction, or could be placebo. Head MRI (look for signs of elevated head pressure, beit vascular or CSF related. 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. Radiologic spectrum of craniocervical distraction injuries. Patients with legitimate CCI or AAI will generally have intermittent induction of symptoms with full rotation, flexion or extension that resolves in netural position, presuming there is no constant crushing of the brainstem or vertebral artery dissection. 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. Supine cervical MRI including T2-w sagittal-oblique sequences at 2mm slice thickness (disc and foraminal health is best evaluated on a supine MRI). 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). Atlantoaxial instability will generally imply axial hypermobility of the atlantoaxial joint itself, which when symptomatic will result in Bow hunters syndrome (positional After hospital discharge, doctors usually control patients at least once a week after discharge on an outpatient basis, to make sure everything is correct before flying back home, thus we recommend to stay in Barcelona after discharge for 10-15 days. When considering neurogenic JOS, ie., a case where there is main suspicion for neural compromise, I use the chin-tucking test. I believe that most of these practitioners mean well. Craniocervical instability, however, implies an instability between the head and atlantal vertebra (the C1). The atlanto-axial (AA) joint is the joint between the first (atlas) and second (axis) vertebrae (bones) in the neck. 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. 2012). 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. En este folleto, aprender sobre la IAA y cmo afecta a las personas con sndrome de Down. The exam should be done lying down, without a neck pillow. Myran R, Kvistad KA, Nygaard OP, Andresen H, Folvik M, Zwart JA. For occipial neuralgia, an ultrasound guided nerve block will cure these symptoms for three hours and thus confirm the diagnosis. Because it doesnt work most of the time, and doesnt cause any lasting results. JRSM Short Rep. 2013 Nov 21;4(12):2042533313507920. doi: 10.1177/2042533313507920. 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. 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. To schedule an appointment, call one of the offices, or book an appointment online. The deep neck flexors should not engage as this lessens the compression. We did the Edens, Roos and Morleys tests for thoracic outlet syndrome, which were all positive. Articles It is crucial to understand that the general minor instabilities involved in AAI and CCI are not the cause of symptoms. The CXA was 138 degrees and the Grabb-Oakes measurement was 8,3mm. 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. This can result in AAI where the bones are less stable and can damage the spinal cord. Thus, I recommend the following studies for craniovenous hypertension and TOS CVH: Craniovasculo-hypertensive disorders (mainly IIH, TOS CVH (!) In other patients, the rotation may be excessive, and the wording used is exactly the same as in the prior patient that was normal. doi: 10.1227/NEU.0b013e3182333859. 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. Epub 2020 Jul 4. Then the patient can make an informed decision about whether or not they want to invest in experimental therapy. Dr. Nic Gay and Dr. Masi Reynolds specialize in getting to the root cause of the problem The instability present between these vertebrae can cause the vertebrae to shift and injure the spinal cord. AAI and CCI are diagnoses that mainly cause the risk for either brainstem damage or injury to the arteries that supply the brain with blood, and this can cause paralysis or stroke if left untreated in cases where there is legitimate evidence for pathology. Epub 2014 May 22. 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. 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. Abbreviations: BDI: basion dens interval, CXA: clivo axial angle, BAI: basion-axial interval, ADI: Atlantoaxial interval. 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. Just like the CXA, this measurement is supposed to aid with objective measurements rather than just eyeballing the images, and writing down your impressions. Copyright Dr Gilete Neurosurgery & Spine Surgery. 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. Strong evidence of clinical correlation must be present from a clinician that is familiar with the signs and triggers in upper cervical instability-cases. However, I also told her that she may end up having fixation surgery in the future to prevent foreseeable compressive damage to the brainstem. Elsevier Publishing. The doctor will tell you which sports and activities are safe for your son/daughter. Why would you jump to the worst possible explanation, and especially when lacking apt evidence? 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. 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. 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. Commonly misunderstood and overemphasized measurements. Clunking and popping that occurs in the upper neck can be scary, but is usually just a sign of facetal rigidity with reduction, meaning that they get stuck and then pop back into place. Once in the Operating Room, surgery is performed under general anesthesia, with Neurophysiological monitoring (SSEP somatosensory evoked potentials), neuronavigation guidance and intraoperative fluoroscopy guidance. Request an appointment or second opinion, refer a patient, find a doctor or view test results with MGfC's secure online services. Common arguments for treatment may be claims that, although the MRI and even upright MRIs are normal, their own DMX scan is positive, or that the MRI, which was deemed normal by the local hospital, in reality shows signs of ruptured ligaments and that this fits with the patients symptoms. The atlanto-occipital joint allows your head to move up and down, while the atlantoaxial joint lets your head rotate. The success rate of this surgery is 80% or greater; however, there are many potential complications and a mortality rate of 5-10%. 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. If you are very concerned that you have craniocervical and atlantoaxial instability, then I recommend getting workups for both these but also relevant differential diagnoses. This, seriously augmented by poor hinge neck postures (Larsen 2018). 2008 Aug 15;33(18):2012-6. doi: 10.1097/BRS.0b013e31817bb0bd. 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. Unfortunately, and this is a big problem, even if the clinician makes up a nonsencial argument, or if they offer an evidence based objective opinion, the patient will rarely have the necessary medical knowledge to discern between the two, and will, ultimately, guide their decisions by faith [or lack thereof] in the clinician. This website uses cookies to improve your experience. Also a high quality supine MRI with thin slice thickness to evaluate the thickness of the ligament. 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. Secondly, and perhaps more importantly, the extent of facetal overap must be measured. However, as stated, in most cases this is just locked facets that suddenly reduce (realign) with a pop. One or 2 out of every 100 children with Down syndrome have symptoms of AAI, but doctors do not know the exact number yet. 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). 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. 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. 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. (I will post the before- and after images when I return to Colombia in August, as they are on a separated hard drive).

Congenital, inflammatory, traumatic, Anaesth pain intensive care 2020;24(1)69-86. 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. Neurosurg Rev. 1977;59 (1): 37-44. Patients with genuine and symptomatic rotational vertebral artery compression will develop symptoms of vertebrobasilar insufficiency when they fully rotate their heads to one or both directions, and may be further worsened if done simultaneous with neck extension (DeKleyn 1927). J Bone Joint Surg Am. 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 (! The surgical treatment for Atlantoaxial instability, when it manifests alone without occipitocervical instability, it mainly consists of a The BDI was 6mm and the BAI was 8mm, which are all farily normal. 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. I have seen patients with a CXA as low as 110 degrees and still did no have any frank brainstem compression. Our surgeons can discuss with you the various treatment options for your specific condition. 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. Posture is done for the rest of your life. The ligaments holding the bones together can also be injured in trauma, or weakened in certain inflammatory conditions such as rheumatoid arthritis or Downsyndrome. She had been out from work for one year at the point of consultation, but her doctors could not find anything wrong with her. This is no longer true. 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). #11760. Ann Rheum Dis. 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. This 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. Copyright 2007-2023. Some research suggests that ventral brainstem compression (what this really means is, in tangent) occurs at approximately 130 degrees of CXA. 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). Would need a flexion extension MRI and correlate to the patients symptoms. 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. La inestabilidad atlantoaxoidea (IAA) es una enfermedad que afecta los huesos de la parte superior de la columna vertebral. In these cases, the direct signs and indirect signs of atlantoaxial subluxation must be objectified. These cookies do not store any personal information. Luxation of the atlantoaxial joints, ie., luxation that surpasses what is seen in Cock Robin syndrome, can also occur with traumatic and gross ligamentous rupture. 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. 14 Postoperative care advices following cervical disc herniation surgery, 4 Predictive factors of the results in Cervical Herniated Disc surgery. In less severe cases, physical therapy can also help. 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. The dorsal lamina of the atlas shifts caudally and ventrally against the spinous process of the axis. 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. This website uses cookies to improve your experience while you navigate through the website. My symptoms are mostly sitting or standing but better laying down, wont doing the CT angiogram then become useless if I do it laying down (my symptoms are dysautonomia-like when standing). 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. Remember that the main dangers of atlantoaxial hypermobility are 1. facetal luxation, and 2., risk for rotational injury to the vertebral artery. If the patient has an elevated Grabb-oakes interval of 10mm and low CXA of 130 degrees, there is some horizontalization (upwards deflection) of the medulla, but no compression from both sides. The 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. Another diagnostic method used is cervical cineradiology, which records joint(s) movement of the entire occipitocervical, atlantoaxial and subaxial joint system. The patient will hinge back at their neck while simultaneously flexing the cranium. Kjetil has also published several peer-reviewed studies on musculoskeletal and neurological topics.
