atlantoaxial instability specialist

An X-ray is low-cost and low-risk, but it does not always tell whether a person has AAI or not. 14 Postoperative care advices following cervical disc herniation surgery, 4 Predictive factors of the results in Cervical Herniated Disc surgery. Larsen K. Occult intracranial hypertension as a sequela of biomechanical internal jugular vein stenosis: A case report. Not sure what you mean here. 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. 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. 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. 2011, Dashti et al. Postural orthostatic tachycardia syndrome (POTS) and its relation to craniovascular dysfunction, Pectineo-femoral pinch syndrome: A common cause of groin & anterior thigh pain and weakness, Chronic spinal pain and radiculopathy: Diagnostic approach and common imaging pitfalls, Neurogenic genital pain: Pudendal neuralgia and inferior hypogastric plexalgia. The ligaments holding the bones together can also be injured in trauma, or weakened in certain inflammatory conditions such as rheumatoid arthritis or Downsyndrome. Tambin conocer las causas, los signos y los sntomas de la IAA. 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. 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. Because of its role in movement, it is, unfortunately, commonly injured. Diagnostic imaging: Spine, 3rd edition. The findings may be quite subtle and are easy to miss outside of dynamic exams. Imaging will prove brainstem compression on [flexion/extension] MRI, and an increased atlantodental interval on flexion/extension CT or x-ray. 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). At the very least, if the clinician has clinical suspicion but no concrete holdingpoints for their diagnosis, they must be honest about this. Knattlia 2, 3038 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. (Fixed rotatory subluxation of the atlanto-axial joint). This category only includes cookies that ensures basic functionalities and security features of the website. The atlantoaxial complex refers to the first two bones of the neck (C1,the atlas, and C2,the axis) as well as the associated collection of ligaments that connect the bones together and the blood vessels that travel through them to the brain. As always, it is important to do a clinical radiological correlation to make an accurate assessment. This, seriously augmented by poor hinge neck postures (Larsen 2018). Both patients had severe symptoms regardless of lying down, wearing a neck brace, etc., and did not get worse nor better when turning or moving their necks. Sometimes, an X-ray shows AAI when there are no symptoms. In my experience, although I usually disagree with their diagnoses, is that Medserena in London has the absolute best upright imaging quality in the world. Anaesth pain intensive care 2020;24(1)69-86. 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. Please understand that no matter how bad you feel, pursuing the wrong diagnosis will not help. ADI laxity is mainly caused by head and neck trauma, so as long as you avoid future collisions, it will probably not deteriorate. Atlantoaxial instability and craniocervical instability are spinal manifestations directly due to ligament laxity. 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. Abbreviations: BDI: basion dens interval, CXA: clivo axial angle, BAI: basion-axial interval, ADI: Atlantoaxial interval. This would apply for patients with obvious hypermobility but who do not have clinical triggers compatible with CCI or AAI (induction of symptoms in flexion, extension or rotation, and complete normalization when in neutral). 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. 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. A lot of things that cause temporary results are just placebo. Stay put for 30-60 seconds, look for worsening of symptoms while in the test. PMID: 25083363; PMCID: PMC4111952. Journal of Neuro-Ophthalmology 2013;33:330337doi: 10.1097/WNO.0b013e318299c292, Alkhotani A. Cerebrospinal Fluid Rhinorrhea Secondary to Idiopathic Intracranial Hypertension. If there are no symptoms, then what reuslts are you talking about? Get the latest news, explore events and connect with Mass General. It is also important to know and evaluate patients concomitant diseases or comorbidities which are frequent in patients affected by Ehler Danlos, such as POTS, Mast Activation Syndrome, cardiac abnormalities etc. See my other articles or YouTube videos for howtos. This website uses cookies to improve your experience. Washington University neurosurgeons have extensive experience treating problems in this area and are recognized nationally as experts in providing innovative treatments for this unique and complex area of the neck. Anaesth Pain & Intensive Care 2018;22(2):238-242. My experience is that most of these patients suffer from craniovascular pathologies, not CCI and AAI. Our surgeons can discuss with you the various treatment options for your specific condition. The most commonly used measures in the radiological evaluation of craniocervical instability and atlantoaxial instability are CXA, Grabb, BDI, BAI, ADI. Clunking, clicking and pain in the upper neck. Patients with craniovenous outlet obstruction due to JOS may induce their symptoms with a Queckenstedts test, that is in essence a manual compression test of the internal jugular veins. DOI: https://doi.org/10.35975/apic.v24i1.1230. 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). We are committed to providing expert caresafely and effectively. 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. Acta Otolaryngol. 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 joint between the upper J Craniovertebr Junction Spine. If nicely timed, around 20 secs after infusion, beautiful visualization of both arteries and veins is permitted). 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! Advanced Surgical Neuro-oncology Fellowship, Complex and Minimally Invasive Spine Deformity Fellowship, Endovascular Surgical Neuroradiology Fellowship, Neurosurgical Spine Innovation Fellowship, Neurosurgical Peripheral Nerve and Spine Fellowship. A patient with positional brainstem compression due to TAL rupture, for example, will develop neurological (ie. 2009), but this is extremely rare. Identifying The Signs Of Cervical Instability. 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). Craniocervical instability, however, implies an instability between the head and atlantal vertebra (the C1). Then the patient can make an informed decision about whether or not they want to invest in experimental therapy. This Congenital, inflammatory, traumatic, Epub 2019 Jun 21. Seemingly unrelated, Higgins et al (2013) and others (Dashti et al 2012, Li et al. Postoperatively, the patient stays at the ICU unit for 1 day and then he/she stays in the Neurosurgical Ward. 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. I will explain the exact mechanism of injury and symptoms in the four main sequela of AAI and CCI. 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. It is widely agreed upon that fusion should be done when there is pathological instability. 15 Piscataqua DriveNewington (Portsmouth), NH, 03801 603-431-3600, 8 Maple Street, Suite 2 Meredith, NH 03253 603-279-1117, 2023 All rights reserved | Sitemap | Legal | Law Firm Essentials by PaperStreet Web Design, Caudal Cervical Spondylomyelopathy (Wobblers). 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. Some top offenders may suggest full craniocervical fusion, ie. 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 914 390 028 It is not due to mild overall instability that does not cause neurovascular conflicts. Higgins N, Pickard J, Lever A. Lumbar puncture, chronic fatigue syndrome and idiopathic intracranial hypertension: a cross-sectional study. 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. 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. What does this mean? In the congenital form of AA instability, the animal is born with abnormal bony or ligamentous connections between the first two vertebrae in the neck. Pain medications and anti-inflammatories are typically also prescribed. 2019) have documented numerous symptomatic cases of jugular vein stenosis at the craniovertebral junction. Dashti SR, Nakaji P, Hu YC, Frei DF, Abla AA, Yao T, et al. It mainly consists of the posterior fusion of the affected vertebrae, in this case, the atlas (C1) and the axis (C2). Flexion and extension imaging fails to demonstrate any sort of brainstem compression. Epub 2020 Oct 16. This category only includes cookies that ensures basic functionalities and security features of the website. In addition to that we would start treatment for thoracic outlet syndrome. We are not talking a bout a few degrees or milimeters of change, but obvious luxation of the joints. At Dr Gilete we are experts in Ehlers Danlos surgery, craniocervical instability EDS,neuro and spine disorders related to EDS and whiplash. 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. Second of all, if there is suggested ADI widening, but a high quality supine MRI with low slice thickness ascertains patency of the majority of the fibers of the TAL, the likelihood of actual complete rupture and future brainstem injury is extremely low. This can also damage the brainstem and produce symptoms similar to what is described above. 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. 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. Basil R. Besh, M.D. Does thoracic outlet syndrome cause cerebrovascular hyperperfusion? Call 314-362-3577forPatient Appointments. 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). 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. Type one involves sole rotary luxation of the facet joints, usually along with damage to either the alar ligaments and capsular ligaments. In addition to reproducible clinical triggers (positions), the patient should preferably undergo a dynamic catheter angiography of the neck. 2014 Apr;5(2):59-64. doi: 10.4103/0974-8237.139199. Lateral bowing of the inferior atlantal facets in netural position is a sign of transverse atlantal ligament laxity. Why do they have results tho when they correct the atlas/axis? This is what I said from the beginning; AAI is not the cause of these symptoms, the exam and triggers do not fit. More information about surgical treatment. Neurol India. 1963;13(5):386396. A common but severely ignorant misunderstanding that some clinicians make (the patient cannot be blamed for thinking like this, but the clinician should set it straight), is the notion that mild to moderate ligamentous instabilities makes the neck (or the whole body for that matter) tense up to protect against the ligamentous instability, even though there are minimal or no clear MRI findings to support this notion, and that this somehow causes all of the patients symptoms. Second, because it is such a controversial topic that lacks medical consensus, poor understanding of the actual mechanism of pathology leads to misunderstandings. Radiologic spectrum of craniocervical distraction injuries. Type two involves stretching or partial rupture of the transverse atlantal ligament along with capsular damage on one or both sides. A critical view on the overdiagnosis of AAI/CCI. In people with Down syndrome, the ligaments (connections between muscles) are lax or floppy. Dissection of the vertebral and carotid arteries is fairly rare and can be excluded through a doppler ultrasound or CT angiogram. If there is a 1mm listhesis, however and the patient has no neurological symptoms and the medulla is utterly free of compression, then performing fusion is completely unnecessary. Patients with hyperrotation of the atlantoaxial joints can also develop Bow hunters syndrome (BHS). Kjetil Larsen is a Researcher and a injury rehabilitation specialist, and is the owner of MSK Neurology. 1927;11(1):155157. This is Bow hunters syndrome, and may be caused by legitimate atlantoaxial instability. Due to the instability in the craniocervical junction deformation can occur to the brainstem, upper spinal cord, and cerebellum. 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. 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. Eur J Pediatr. DOI: 10.3171/2015.1.FOCUS14791. In less severe cases, physical therapy can also help. Ross & Moore. TOS is often considered a mere upper limb nerve pathology, but this is not the case. This website uses cookies to improve your experience while you navigate through the website. 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. Yang SY, Boniello AJ, Poorman CE, Chang AL, Wang S, Passias PG. This, of course, must be evaluated on a case-to-case basis. No improvement! had been excluded by her primary care physicians and local hospital. 2008 Aug 15;33(18):2012-6. doi: 10.1097/BRS.0b013e31817bb0bd. You also have the option to opt-out of these cookies. Moderator. Let us look closer at these clinical entities and their associated symptoms, imaging findings, and, importantly, clinical triggers. 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. 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. Booking 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. My experience has been that these approaches do not work, and certainly do not cause long term results. In cases of hyperlaxity, It is not uncommon to find subaxial cervical alterations (levels below C3 to C7 . Signs of ligamentous damage. Fielding JW, Hawkins RJ. In such cases I tell my patients that, yes, you do have mild AAI, but it is not causing your symptoms. Another common belief is that this mild deflection stretches the brainstem and somehow causes damage. This website uses cookies to improve your experience while you navigate through the website. 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. 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. Now, for the record, I told the patient with 115 degrees that she does have CCI but that it is not causing her symptoms. 2. Org. Instability in the hip can result in dislocation, ligament tears, muscle damage and wear of the joint. 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. In previous epidemiologic studies, the prevalence of atlantoaxial instability in persons with Down syndrome was found to be between 9% and 31%. Case Rep Neurol 2019;11:295298, Waldock WJ, Higgins NJ, Axon P. A case report of gastroparesis resolved by styloidectomy. Thus, it is important to measure both the percentile overlap as well as the degree of rotation bidirectionally. Moreover, I have heard numerous similar stories from other patients. We offer diagnostic and treatment options for common and complex medical conditions. Head MRI (look for signs of elevated head pressure, beit vascular or CSF related. Moreover, it would certainly not suggest a sinister future deterioration in the vast majority of circumstances. Thus, beware that a low clivo-axial angle (CXA) is often overinterpreted and abused as supportive evidence. If the latter, could be JOS obstruction, or could be placebo. Radiographics 2000;20:S237-50. 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. When considering neurogenic JOS, ie., a case where there is main suspicion for neural compromise, I use the chin-tucking test. Although there were no current grounds for surgery? Complete rupture of the transverse atlantal ligament, however, will generally promote dorsal and cranial migration of the odontoid process (the atlantodental interval (ADI) will be increased (> 3,5mm) while in flexion) causing it to compress the brainstem dorsally (in the upper neck), or to migrate into the foramen magnum and compress the brainstem there (basilar invagination), where the tip of the odontoid will be seen far above the Chamberlains line, whereas it in normal patients sits about 2mm below the line. The atlantoaxial segment consists of the atlas (C1) and axis (C2) and forms a complex transitional structure bridging the occiput and cervical spine. You also have the option to opt-out of these cookies. Symptoms of brainstem compression are respiratory crisis and quadriplegia, but can also manifest more diffusely. The complex anatomy of the C1 and C2 bones of your neck is unique both in appearance and function. Then, if there are not even sufficient findings for surgery, how can one possibly give such a fatal prognosis? Necessary cookies are absolutely essential for the website to function properly. For example, if there is a C4-5 anterolisthesis with resultant chronic radiculopathy, C4-5 ADCF would often be utilized as operative treatment. 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. Int J Spine Surg. 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. Strong evidence of clinical correlation must be present from a clinician that is familiar with the signs and triggers in upper cervical instability-cases. Articles The success rate of this surgery is 80% or greater; however, there are many potential complications and a mortality rate of 5-10%. This is easily seen on imaging, especially on CT, as the alignment of the joint will be unequivocally abnormal to the extent that would not be achievable without tremendous ligamentous injury. 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. J Neurosurg Spine. 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. 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. 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. 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. 10 things you should know about Cervical Disc Replacement. 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. This is a major component in the workup for TOS CVH). PMID: 32623537; PMCID: PMC8121728. 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). 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. If the brainstem compression is not positional, ie., it is seen even on neutral imaging, then the symptoms would be expected to be constant. The report claimed that there were signs of ligamentous rupture and bidirectional subluxation upon rotation in the atlantoaxial joints. 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. 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). And, of course, to determine whether or not the findings actually correlate with the patients symptoms and clinical exam. Just anterior to the transverse process in patients with normal necks, emerge the internal jugular veins as well as the glossopharyngeal, vagus and accessory nerves. Grabb-Oakes interval is another measurement that is often misunderstood. Must be carefully evaluated and correlated with the patients symptoms). Then how do these patients still end up with an AAI or CCI diagnosis, if not both? Accessory nerve compression can cause weakness of the trapezius and sternocleidomastoid muscles, but can also cause cervical dystonia. If the measurements are within normal limits, the likelihood of dangerous sequelae are low, if not absent. Moreover, tractioning the neck of these vulnerable patients can often cause undesirable effects. 333 Earle Ovington Blvd, Suite 106. This is reasonable. 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.
