Thus, beware that a low clivo-axial angle (CXA) is often overinterpreted and abused as supportive evidence. 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 Neurology. Stay put for 30-60 seconds, look for worsening of symptoms while in the test. Deliganis AV, Baxter AB, Hanson JA, et al. Treatment depends on your son/daughters symptoms. Elsevier Publishing. In other words, the vertical distance between the head and the spine. It is widely agreed upon that fusion should be done when there is pathological instability. Magnetic resonance imaging assessment of the alar ligaments in whiplash injuries: a case-control study. Pain medications and anti-inflammatories are typically also prescribed. nr. Copyright statement 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! Search for condition information or for a specific treatment program. 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. A lof patients have clicking and clunking in the neck along with severe suboccipital pain. But if there is lots of space for the medulla, such invasive surgery simply is not warranted. It does certainly insinuate some instability and ligamentous laxity, and can certainly result in greater level of wearing and tearing of the facet joints and causing some neck pain and joint effusions, but it can not be said to be any form of sinister AAI or CCI due to lacking neurovascular conflicts. Contact, Terms & conditions The atlanto-axial (AA) joint is the joint between the first (atlas) and second (axis) vertebrae (bones) in the neck. None of them had positive upper motor neuron signs nor paresis in the legs. Necessary cookies are absolutely essential for the website to function properly. If the patient is indeed positionally symptomatic, however, and there is compatible imaging evidence, either atlantoaxial fusion, transverse foraminotomy or certain physical therapies may be warranted depending on how severe the findings and symptoms are.

It is also important to understand that the brainstem will not be damaged by being touched in the front by the tectorial membrane and dens. Request Appointment. Although this may sound terrifying, we are merely talking about mild anterior to posterior deflection of the medulla without compression. If its caused by rotation (rare), manipulation may temporarily improve jugular outlet passage, but it will not last. Grabb-Oakes interval is another measurement that is often misunderstood. I diagnosed her with mild (benign) atlantoaxial instability and TOS CVH. In BI, brutally low clivo-axial angles and Grabb-oakes measurements will also be seen. 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. First, need I mention the notion that there is tremendous money in this patient group, and that if treatment goes wrong, becuase they have already burned their bridges with their GPs, no one will listen nor care? And, fair enough, I do not expect blind trust nor compliance. This may cause the patient to become afraid and to google their symptoms, which in and by itself is reasonable enough. Fielding JW, Hawkins RJ. 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. Anaesth pain intensive care 2020;24(1)69-86. Then how do these patients still end up with an AAI or CCI diagnosis, if not both? Wake up and walking begins on the second day after surgery. 10 things you should know about Cervical Disc Replacement. Although the complete differentiation between this and CCI or even occipital neuralgia is something that is complicated and must be done on individual basis after examination, we can, in essence, say that suboccipital pain that worsen with shoulder loading tends to be TOS or occipital neuralgia, whereas suboccipital symptoms that induce when lying down or being upright regardless of neck position tends to be TOS CVH. The success rate of this surgery is 80% or greater; however, there are many potential complications and a mortality rate of 5-10%. English. 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. The alignment of the atlas itself isnt really the problem; the problem is whether or not a rotation or a horizontal glide is causing encroachment of the jugular outlet. to analyze our web traffic. What does this mean? Evaluation of the Cause of Internal Jugular Vein Obstruction on Head and Neck Contrast Enhanced 3D MR Angiography Using Contrast Enhanced Computed Tomography. 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). Acta Otolaryngol. If this was the case, ie., if the brainstem and medulla was being stretched, then the patient would highly likely get neurological symptoms that improve with extension and worsen with flexion (as patients with legitimate tethered cord syndrome do), and would certainly have a positive Slump test, a test which stretches the spinal cord. 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. Clinical signs of such an injury include neck pain, weakness in all limbs, and potentially paralysis from the neck down and death. Imaging will prove brainstem compression on [flexion/extension] MRI, and an increased atlantodental interval on flexion/extension CT or x-ray. In these cases, the direct signs and indirect signs of atlantoaxial subluxation must be objectified. (2019) documented another case where a patient with RA developed odontoid fracture and subsequent anterolateral subluxation of the atlantoaxial joint. 2019) have documented numerous symptomatic cases of jugular vein stenosis at the craniovertebral junction. Two important questions arise: Does the patient actually develop (even if just from time to time) develop frank facetal luxations causing the neck to lock up? A positive test would be interpreted by unbearable head pressure, lightheadedness, worsening of headache, etc., within about 20-30 seconds. Instability in the hip can result in dislocation, ligament tears, muscle damage and wear of the joint. 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. Henderson FC Sr, Rosenbaum R, Narayanan M, Koby M, Tuchman K, Rowe PC, Francomano C. Atlanto-axial rotary instability (Fielding type 1): characteristic clinical and radiological findings, and treatment outcomes following alignment, fusion, and stabilization. PMID: 25083363; PMCID: PMC4111952. The patient had headache, dizziness, fatigue, pain in the arms and chest and often felt difficulty breathing. 2021 Jun;44(3):1553-1568. doi: 10.1007/s10143-020-01345-9. Another patient was told by a well-known pain physician in the US that she had brainstem compression and required several expensive prolotherapy procedures. 2008). Atlantoaxial and craniocervical instability are both real and potentially sinister diagnoses that require treatment. Copyright 2007-2023. Traumatic Atlantoaxial Lateral Subluxation With Chronic Type II Odontoid Fracture: A Case Report. This website uses cookies to improve your experience. I will update the article when I am back home in Colombia in the beginning of August. Why do they have results tho when they correct the atlas/axis? Styloidectomy and Venous Stenting for Treatment of Styloid-Induced Internal Jugular Vein Stenosis: A Case Report and Literature Review. AAI is less common in adults with Down syndrome. In such cases I tell my patients that, yes, you do have mild AAI, but it is not causing your symptoms. My experience is that most of these patients suffer from craniovascular pathologies, not CCI and AAI. BHS implies rotational compression of the vertebral arteries, which are two out of four arteries that supply the brain (two internal carotid and two vertebral arteries). 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. This is not good medical practice. Burry HC, Tweed JM, Robinson RG, Howes R. Lateral subluxation of the atlanto-axial joint in rheumatoid arthritis. It is not a substitute for medical advice and should not be used to treatment of any medical conditions. In addition to reproducible clinical triggers (positions), the patient should preferably undergo a dynamic catheter angiography of the neck. 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. Faris AA, Poser CM, Wilmore DW, et al.. Radiologic visualization of neck vessels in healthy men. The problem has received various names such as mere jugular vein compression, venous eagles syndrome, but I have called it jugular outlet syndrome (JOS), as it is a problem that not only affects the craniovenous outflow, but also several cranial nerves, and can be culpable in various strange neurological disorders (Read my atlas article (link) I also have an upcoming paper on this topic that I hope to release this or next year). Kjetil Larsen is a Researcher and a injury rehabilitation specialist, and is the owner of MSK Neurology. 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 brainstem must be compressed from the front and the back, not merely deflected from the front. Common findings: Ovalization of the orbitae, dilated optic nerve sheaths, pituitary concavity, Chiari malformation, tight brain appearance, jugular vein compression with or without white-vessel signs, dilation or narrowing of the lateral and possibly third ventricles, periventricular ependymal T2 FLAIR hyperintensities), Neck MRI (general evaluation of the neck integrity), CT angiogram of the head neck and subclavian arteries with the arms raised (contrast infusion via femoral vein. 2019 Oct;130:129-132. doi: 10.1016/j.wneu.2019.06.100. Unfortunately, she was not compliant to the treatment that I prescribed (TOS, TOS CVH) other than the treatment for AAI, which she was convinced that was her problem. Supine cervical MRI including T2-w sagittal-oblique sequences at 2mm slice thickness (disc and foraminal health is best evaluated on a supine MRI). Global Spine J. Gweon HM, Chung TS, Suh SH. Exam for bow hunters syndrome is done dynamically, but thats aother exam. 1977;59 (1): 37-44. Now, what if there is no frank compression nor clinically medullary signs and triggers, but there is a very small space both infront and behind the medulla that has been gradually getting worse. It is better to let your doctor know if your son/daughter is having symptoms. One is especially predisposed to this problem if the affected vertebral artery is highly dominant (much higher caliber than its contralateral counterpart) or if the contralateral artery is extremely hypoplastic, or, finally, the contralateral artery terminates as the posterior inferior cerebellar artery rather than at the basilar artery (Josy & Daily, 2015). Org. Moreover, craniovascular disorders often fluctuate depending on whether or not the patient is upright or lying down (sometimes lying down is worse, sometimes standing up makes it worse), and do certainly not return to normal, symptom-free status when the neck is placed in neutral position. Headaches certainly can develop from instability of C1-2. This may not apply for all of them, but it is a common problem which makes this patient group especially susceptible to become perfect victims of medical vulturism. No improvement! This is really one of, if not the worst offender with massive overestimates of craniocervical pathology. Upright cervical MRI in flexion, extension and maximal bi-directional rotation. 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. ), induction of symptoms (all or nearly all of your symptoms, not some neck pain) with maximal rotation, nor during flexion or extension. It is, as we say, in tangent with the dens and tectoral ventrally alone. More information about surgical treatment. 3. 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). 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. 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). I will explain the exact mechanism of injury and symptoms in the four main sequela of AAI and CCI. Li M, Gao X, Rajah GB, Liang J, Chen J, Yan F, et al. Atlantoaxial fixation: overview of all techniques. Treatment, depending on the neurological symptoms and related pain, may be surgery. Ultimately, the reader must discern for themselves. Albeit still a surgically treated problem. 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. In cases of hyperlaxity, It is not uncommon to find subaxial cervical alterations (levels below C3 to C7 . Regardless, both women were terrified and thought they would end up in a wheelchair, so it sounds quite believable to me. This is not dangerous, but can cause some popping, restriction in movement, and some pain upon articulation. 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). The complex anatomy of the C1 and C2 bones of your neck is unique both in appearance and function. English +34 93 220 28 09 Espaol +34 93 198 34 24 The same applies for conservative strategies to reduce internal jugular vein compression. Whats interesting, regardless, is that one year after we had the first consultation she underwent another uMRI (due to lack of improvement of symptoms), which showed completely resolution of the atlantoaxial subluxations, which were now overlapping at about 30%; 300% improvement (remember: >20% is normal). For occipial neuralgia, an ultrasound guided nerve block will cure these symptoms for three hours and thus confirm the diagnosis. I believe that most of these practitioners mean well. J Bone Joint Surg Am. I, personally, although I created my own manipulation protocol for this problem ALMOST NEVER use it. 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. 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. Because of its role in movement, it is, unfortunately, commonly injured. Atlantoaxial malalignment is best visualized on a lateral view. 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. In severe cases, I recommend postural corrections (appropriate, not generic) along with styloidectomy and transversectomy. (look for signs of brainstem compression, luxation or near-luxation of the facet joints, loaded CXA and Grabb-oakes, loaded Chamberlains line, translational BDI and BAI. Treatment is via one of two methods: 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.

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. the basion-dens interval, is the distance between the tip of the clivus and tip of the C2. (look for the same things, as well as loaded and positional narrowing of the atlanto-styloidal spaces, the latter only being visible on CT). Journal of Neuro-Ophthalmology 2013;33:330337doi: 10.1097/WNO.0b013e318299c292, Alkhotani A. Cerebrospinal Fluid Rhinorrhea Secondary to Idiopathic Intracranial Hypertension. Moreover, I have heard numerous similar stories from other patients. Basil R. Besh, M.D. For example, I have seen patients with 45 degrees of rotation (which is higher than normal) between the C1-2 that had completely normal overlap due to large facets, and I have seen patients with 30 degrees of rotation (which is usually completely normal) with poor overlap and AAI, due to small facetal surfaces. I recommend sticking to clinics that have good reputations and good imaging protocols. I recommend first measuring the degree of rotation between the C1 and C2 by drawing a line from the bifid process to the middle of the anterior aspect of the vertebra, and then another line from the posterior to the anterior tubercles of the C1. The bones are susceptible to fracture from high-energy impact such as falls or car accidents, especially in the elderly. In the cases where it is not possible to obtain autologous bone graft, heterologous graft (artificial bone) may also be used. All conventional things like heart and lung problems, MS, cancer, infections etc. In 18 patients, dynamic images showed vertical, mobile and at-least partially reducible atlantoaxial dislocation. Most cases of mild to moderate unilateral compression, sometimes even intermittent occlusion, is asymptomatic due to contribution from the contralateral VA (Faris et al. 2008 Aug 15;33(18):2012-6. doi: 10.1097/BRS.0b013e31817bb0bd. The atlantoaxial segment consists of the atlas (C1) and axis (C2) and forms a complex transitional structure bridging the occiput and cervical spine. 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). 2014 Feb;11(1):75-82. ncbi.nlm.nih.gov/pubmed/24321024, Higgins JN et al. 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. 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. However, as stated, in most cases this is just locked facets that suddenly reduce (realign) with a pop. Facetal locking with rigid torticollis (Cock Robin syndrome) or similar, in cases where there is no neurological compromise, is less dangerous. Abbreviations: BDI: basion dens interval, CXA: clivo axial angle, BAI: basion-axial interval, ADI: Atlantoaxial interval. Last Update [site_last_modified date_format=Y-m-d H:i:s].

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. Neurol India. 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. It is possible to do it with extension and rotation, etc., but it is usually not necessary. He specializes in the treatment of chronic pain and has developed several distinctive protocols both with regards to diagnosis and conservative rehabilitation of difficult conditions. Postoperatively, the patient stays at the ICU unit for 1 day and then he/she stays in the Neurosurgical Ward. Specialist imaging research to help diagnosis. Surgical management is recommended for those with severe signs and for those who have tried and failed medical management. However, appropriate inclusive criteria must be used to render the diagnoses; subtle findings and the lack of a strong clinical correlation is not enough, and will easily lead to misdiagnosis and related anxiety and suffering. 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). 1927;11(1):155157. The surgical treatment for Atlantoaxial instability, when it manifests alone without occipitocervical instability, it mainly consists of a 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. Remember that the main dangers of atlantoaxial hypermobility are 1. facetal luxation, and 2., risk for rotational injury to the vertebral artery. 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. Commonly misunderstood and overemphasized measurements. Yang SY, Boniello AJ, Poorman CE, Chang AL, Wang S, Passias PG. This means routine X-rays are not helpful. 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 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. I completely disagree with this and, once again, refer to common sense thinking that if the joint positions are within normal limits then there is very little risk, if any, of any damage to the spinal cord or segmental arteries. 2014 Aug;4(3):197-210. doi: 10.1055/s-0034-1376371.
