Lateral cervical x-ray and flexion-extension views can give us complementary information in regards to atlantoaxial instability, although it does not seem indicated as the first choice method of diagnosis. Followup with a dynamic CT, supine MRI or similar to confirm potentially equivocal findings is warranted. Upright cervical MRI in flexion, extension and maximal bi-directional rotation. This madness must stop. She was never evaluated for clinical correlation for these alleged findings, ie., no one evaluated if these findings had actual compatibility with her clinical symptoms and, especially, triggers. Followup, as mentioned above, can be a CTV, volume flow doppler exam, and potentially catheter venography and manometry as one additional confirming pre-surgical step to ascertain actual raised intravenous pressures. 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. Org. In the cases where it is not possible to obtain autologous bone graft, heterologous graft (artificial bone) may also be used. Because of its role in movement, it is, unfortunately, commonly injured. The surgical treatment for Atlantoaxial instability, when it manifests alone without occipitocervical instability, it mainly consists of a If you or your veterinarian is concerned that your It is not a substitute for medical advice and should not be used to treatment of any medical conditions. Another diagnostic method used is cervical cineradiology, which records joint(s) movement of the entire occipitocervical, atlantoaxial and subaxial joint system. Faris AA, Poser CM, Wilmore DW, et al.. Radiologic visualization of neck vessels in healthy men. 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 other side of the AAI/CCI coin is the risk for facetal luxation; a less sinister-, but still a problem that warrants surgical treatment. Atlas and axis screws are joined in each side by lateral bars that are unifying the instrumented fusion system. Signs of ligamentous damage. 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. Bow hunters syndrome revisited: 2 new cases and literature review of 124 cases. As always, it is important to do a clinical radiological correlation to make an accurate assessment. Although there were no current grounds for surgery? 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. Would this mean that upper cervical chiropractors (orthogonal, blair technique, gonstead, etc.) Then, if there are not even sufficient findings for surgery, how can one possibly give such a fatal prognosis? Radiographics 2000;20:S237-50. 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. 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. Styloidectomy and Venous Stenting for Treatment of Styloid-Induced Internal Jugular Vein Stenosis: A Case Report and Literature Review.

Does thoracic outlet syndrome cause cerebrovascular hyperperfusion? PMID: 25210334; PMCID: PMC4158632. 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. 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. 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. 2019) have documented numerous symptomatic cases of jugular vein stenosis at the craniovertebral junction. Your email address will not be published. These problems will mainly endanger the brainstem. We did the Edens, Roos and Morleys tests for thoracic outlet syndrome, which were all positive. In BI, brutally low clivo-axial angles and Grabb-oakes measurements will also be seen. Secondly, and perhaps more importantly, the extent of facetal overap must be measured. This site complies with the HONcode standard for trustworthy health information: verify here. November 19, 2014 at 8:19 pm. Eur J Pediatr. 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. More information about surgical treatment. This, of course, must be evaluated on a case-to-case basis. How is one supposed to know, if no one knows what you have in the first place? the section on bow hunters syndrome. And, although there was zero evidence of brainsstem compression, she did indeed have subluxation of atlantoaxial joints with around 10% of overlap when turning to the side. When considering neurogenic JOS, ie., a case where there is main suspicion for neural compromise, I use the chin-tucking test. 1963;13(5):386396. had been excluded by her primary care physicians and local hospital. 2020). The joint between the upper spine and base of the skull is called the atlanto-axial joint. We were referred to a specialist vet (swift in Wetherby) who thinks it is AAI but unless she regains use of her legs they cannot operate 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). Look for signs of retinal hypertension (subtle copper wiring, AV nicking, tortuosity of the arterioles, generalized vasospasm or papilledema. This is a component of TOS CVH in most circumstances, in my experience, but can certainly scare the patient into believing that they have sinister CCI or AAI due to the location of the pain along with heavy cracking and other symptoms. 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. Patient resources for the Down Syndrome Program. Another patient was told by a well-known pain physician in the US that she had brainstem compression and required several expensive prolotherapy procedures. It is crucial to understand that the general minor instabilities involved in AAI and CCI are not the cause of symptoms. ), induction of symptoms (all or nearly all of your symptoms, not some neck pain) with maximal rotation, nor during flexion or extension. It is not due to mild overall instability that does not cause neurovascular conflicts. The same applies for conservative strategies to reduce internal jugular vein 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. Grabb-Oakes interval is another measurement that is often misunderstood. 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. This can result in AAI where the bones are less stable and can damage the spinal cord. PMID: 749697; PMCID: PMC1000289. The atlanto-occipital joint allows your head to move up and down, while the atlantoaxial joint lets your head rotate. Instability in the hip can result in dislocation, ligament tears, muscle damage and wear of the joint. 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. In previous years, doctors thought all people with Down syndrome should have regular X-rays to check for AAI. In addition to that we would start treatment for thoracic outlet syndrome. 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. 3. 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. If unavailable, a CT angiogram can be used, but is less sensitive. I believe that most of these practitioners mean well. Flexion and extension imaging fails to demonstrate any sort of brainstem compression. 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. Your email address will not be published. Atlas screws are generally placed in the lateral masses. It is, as we say, in tangent with the dens and tectoral ventrally alone. Jugular outlet obstruction is commonly seen in patients with upper cervical horizontal facetal misalignment, and especially if they have broad transverses processes or a posteriorly angulated styloid process (Gweon et a. When rotated to the right, making sure that the axial alignment of the imaging program is aligned with the spinal column longitudinally, compare the anterior aspect of the right facet vs. the facet of the C2, and the posterior aspect of the left facet vs. the facet of the C2 and calculate the actual percentile of overlap. With the increasing dependence on smartphones, computers, and other devices in our modern 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. The diagnosis can be made by means of an Upright MRI (magnetic Resonance Imaging) or with a cervical CT scan with 3D reconstruction. 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. 2014 Apr;5(2):59-64. doi: 10.4103/0974-8237.139199. Sometimes, an X-ray shows AAI when there are no symptoms. Dr. Christopher Williams | 07/09/2020. Exam for bow hunters syndrome is done dynamically, but thats aother exam. This website uses cookies to improve your experience. AAI is less common in adults with Down syndrome. Acute or chronic spinal cord compression causing clinical signs consistent with an upper cervical myelopathy can result from this instability [2]. Her symptoms, however, did not at all change when changing her neck position and she had never had torticollis. 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. Our surgeons can discuss with you the various treatment options for your specific condition. Pain medications and anti-inflammatories are typically also prescribed. Patients with hyperrotation of the atlantoaxial joints can also develop Bow hunters syndrome (BHS). If someone has an ADI of 4.5mm, can this be treated via physical therapy, or is it too much instability? Now, the I was told is clearly second-hand information, and I cannot guarantee its accuracy. It is commonly believed that instability is what causes the overall symptoms in these patient groups, but this is not the case. Yang SY, Boniello AJ, Poorman CE, Chang AL, Wang S, Passias PG. However, as stated, in most cases this is just locked facets that suddenly reduce (realign) with a pop. Neurosurg Rev. 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. What Is Atlanto-Axial Instability (AAI)? This may cause the patient to become afraid and to google their symptoms, which in and by itself is reasonable enough. The reason why AAI and CCI are potentially associated with so many symptoms such as headache, dizziness, etc., is due to the potential for neurovascular conflict. Medullopathy (signal changes, cord damage) will not occur by mere deflection, which is also evident by the blatant lack of upper motor neuron findings in these alleged brainstem compression patients. I am not saying it is easy. 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). 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. Another problem with regards to rotation, is that the measurements are often done wrong. 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. nr. This, however, is very rarely the case with this patient group in my experience. Education 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. 1-Craniocervical instability, levels C0-C1 (Occipital-atlas). The complex anatomy of the C1 and C2 bones of your neck is unique both in appearance and function. 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. About 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. As stated, although rooted in postural dysfunction, this is not really a problem of pathological instability, and therefore I dont recommend neck fusion to treat this problem. Why rely on Washington University experts for treatment of your atlantoaxial instability? 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! 2011, Dashti et al. Posture is done for the rest of your life. 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). Typically, complete membraneous ruptures of the CVJ may cause dislocation between the head and neck, resulting in positional dissociation between the the two. 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. But if there is lots of space for the medulla, such invasive surgery simply is not warranted. Atlantoaxial fixation: overview of all techniques. 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. 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. In less severe cases, physical therapy can also help. From the beginning, the patient doubted my diagnosis that this was a craniovascular problem because she felt pain in the suboccipital area, had cracking and clunking, and felt compatible with several things she had read online and on facebook forums. The symptoms will completely resolve when returning to neutral position; usually even a few degrees reduction is enough to normalize flow. 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. Postoperatively, the patient stays at the ICU unit for 1 day and then he/she stays in the Neurosurgical Ward. 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. Articles The instability present between these vertebrae can cause the vertebrae to shift and injure the spinal cord. #11760. My poor baby has become completely lame and incontinent in the last 48 hours. Aggressive craniovertebral junction ligamentous injuries can also result in vertical displacements. 2012). We also use third-party cookies that help us analyze and understand how you use this website. 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. If it is, however then flexion/extension and rotational imaging to exclude positional facetal luxation is warranted. A review of the diagnosis and treatment of atlantoaxial dislocations. We can still treat it preventatively, but it wont resolve the symptoms. If your child has symptoms of AAI, the doctor will suggest an X-ray. Craniocervical Instability (CCI), also known as the Syndrome of Occipitoatlantialaxial Hypermobility. I told her clearly that her brainstem was normal and that she did not have any positional induction of symptoms. Why would you jump to the worst possible explanation, and especially when lacking apt evidence? 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. zen , nal , Avcu S. Flow volumes of internal jugular veins are significantly reduced in patients with cerebral venous sinus thrombosis. Necessary cookies are absolutely essential for the website to function properly. It baffles me when I see patients with 130 degree CXA and some additional signs of mild/moderate laxities being butchered with C0-T1 surgery despite there being NO instability in the cervical spine and only mild findings in the upper neck that are not causing any neurovascular conflicts nor facetal lockups (eg., Cock Robin syndrome). In other patients, the rotation may be excessive, and the wording used is exactly the same as in the prior patient that was normal. Both positional (ie., upright. 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. PMID: 33064218. Supine cervical MRI including T2-w sagittal-oblique sequences at 2mm slice thickness (disc and foraminal health is best evaluated on a supine MRI). 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. 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. All conventional things like heart and lung problems, MS, cancer, infections etc. BDI, ie. 2015. Training is done carefully twice per week. Imaging will prove brainstem compression on [flexion/extension] MRI, and an increased atlantodental interval on flexion/extension CT or x-ray. Uniondale, NY Location HSS Long Island The Omni. The doctor will tell you which sports and activities are safe for your son/daughter. 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).
