For TOS CVH the patient will generally feel better when stress is reduced along with taking beta blockers (confer with your doctor). Abbreviations: BDI: basion dens interval, CXA: clivo axial angle, BAI: basion-axial interval, ADI: Atlantoaxial interval. 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. However, if the patient has symptoms regardless of being in rotation or not, and has never had a case of alantoaxial rotary fixation, then there is no evidence that this is the cause of the patients symptoms, even if it, indeed, may be a bit loose. (2019) documented another case where a patient with RA developed odontoid fracture and subsequent anterolateral subluxation of the atlantoaxial joint. The doctor will tell you which sports and activities are safe for your son/daughter. Neurosurg Rev. 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. However, I also told her that she may end up having fixation surgery in the future to prevent foreseeable compressive damage to the brainstem. Headaches certainly can develop from instability of C1-2. The dorsal lamina of the atlas shifts caudally and ventrally against the spinous process of the axis. Necessary cookies are absolutely essential for the website to function properly. How is possible for them to have results when there is no symptomatic AAI/CCI? Dr. Vicen Gilete, MD, Neurosurgeon & Spine Surgeon. 2014 Feb;11(1):75-82. ncbi.nlm.nih.gov/pubmed/24321024, Higgins JN et al. Another common belief is that this mild deflection stretches the brainstem and somehow causes damage. 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. 2011 Apr;15(1):41-47. 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. Foramen magnum decompression or syrinx manipulation was not performed in any patient. This category only includes cookies that ensures basic functionalities and security features of the website. 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). 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. Eur J Pediatr. Traumatic Atlantoaxial Lateral Subluxation With Chronic Type II Odontoid Fracture: A Case Report. I diagnosed her with mild (benign) atlantoaxial instability and TOS CVH. 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. Copyright Dr Gilete Neurosurgery & Spine Surgery. 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. Copyright 2007-2023. 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. 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 Diagnostic imaging: Spine, 3rd edition. Maybe they temporary fix some compression? Exam for bow hunters syndrome is done dynamically, but thats aother exam. In addition to reproducible clinical triggers (positions), the patient should preferably undergo a dynamic catheter angiography of the neck. I hope that, by now, the reader has understood the importance that clinical measurements, actual pathology and clinical triggers should go hand in hand. Patients with hyperrotation of the atlantoaxial joints can also develop Bow hunters syndrome (BHS). What cervical artificial disc should I choose? Atlantoaxial instability will generally imply axial hypermobility of the atlantoaxial joint itself, which when symptomatic will result in Bow hunters syndrome (positional compression or damage to the vertebral arteries) or Cock Robin syndrome (positional facetal dislocation without reduction). 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). Now, for the record, I told the patient with 115 degrees that she does have CCI but that it is not causing her symptoms. 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. 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. 2021 Jun;44(3):1553-1568. doi: 10.1007/s10143-020-01345-9. English. In patients with Ehler Danlos syndrome, instability is present frequently in several segments, generally C0-C1-C2 (from occipital to axis). Dr. Nic Gay and Dr. Masi Reynolds specialize in getting to the root cause of the problem 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. This is a major component in the workup for TOS CVH). This increased mobility causes headache and cervical pain as well as signs of compression of adjacent neural elements that form cervicomedullary syndrome. Another diagnostic method used is cervical cineradiology, which records joint(s) movement of the entire occipitocervical, atlantoaxial and subaxial joint system. For the sake of relevance, this article will mainly address ligamentous and muscular injuries, as these topics, especially when mild, are much more controversial than incidences of CVJ fracture. 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. Bow hunters syndrome revisited: 2 new cases and literature review of 124 cases. Kjetil Larsen is a Researcher and a injury rehabilitation specialist, and is the owner of MSK Neurology. Contact, Terms & conditions DMX I dont recommend getting a DMX. 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. 2019 Feb 22;13(1):79-83. doi: 10.14444/6010. The atlanto-axial (AA) joint is the joint between the first (atlas) and second (axis) vertebrae (bones) in the neck. If it is, however then flexion/extension and rotational imaging to exclude positional facetal luxation is warranted. The report claimed that there were signs of ligamentous rupture and bidirectional subluxation upon rotation in the atlantoaxial joints. 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 atlantoaxial subluxation may exist in patients neutral position (without neck movement) or may occur in relation to neck rotation movements (when the patient moves the neck to the right and left). Moreover, I have heard numerous similar stories from other patients. If combined with Chiari malformation, compression of the cerebellar tonsils can cooccur and will occur with lower measurements than normally needed to cause brainstem compression alone, due to filling of the space behind it (the descended cerebellum). It is different from other joints in the vertebral The ligaments holding the bones together can also be injured in trauma, or weakened in certain inflammatory conditions such as rheumatoid arthritis or Downsyndrome. However, if there is obvious compromise of a ligament but there is no evidence of sinister hypermobility or structural displacement (eg., very high ADI), the ligamentous should be further examined with high-resolution T2 FLAIR imaging with low slice thickness (supine imaging!) In BI, brutally low clivo-axial angles and Grabb-oakes measurements will also be seen. Epub 2019 Jun 21. 2015. 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 In these cases, the direct signs and indirect signs of atlantoaxial subluxation must be objectified. It is not due to mild overall instability that does not cause neurovascular conflicts. Surgical management is recommended for those with severe signs and for those who have tried and failed medical management. 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. 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. Facetal locking with rigid torticollis (Cock Robin syndrome) or similar, in cases where there is no neurological compromise, is less dangerous. Sometimes, an X-ray shows AAI when there are no symptoms. The atlas can sublux anteriorly, posteriorly, laterally, or vertically. Seemingly unrelated, Higgins et al (2013) and others (Dashti et al 2012, Li et al. Anaesth pain intensive care 2020;24(1)69-86. The ligaments involved are the transverse, alar and capsular ligaments. 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). This is one of the biggest offenders along with DMX and CXA, causing massive confusion, coercion, and misdiagnosis. Early stage) and constant compression (if seen on mri, moderate, if seen on CT, severe) of these structures may occur. 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. Additionally, spinal instability in the form of spondylolisthesis 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. This may cause the patient to become afraid and to google their symptoms, which in and by itself is reasonable enough. 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. Dysautonomia when standing up is often related to craniovascular problems, whereas difficulty holding the head up suggests mumscular damage. 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. Neurologic signs of a cranial cervical myelopathy typically present at a young age and can range from cervical pain (hyperesthesia) to paralysis. doi: 10.1227/NEU.0b013e3182333859. He also found that severe misalignment of these joints were often associated with Chiari malformation, basilar invagination, and various other pathologies. 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. Any cookies that may not be particularly necessary for the website to function and is used specifically to collect user personal data via analytics, ads, other embedded contents are termed as non-necessary cookies. In vertical dissociation of the CVJ, the main dangers will similarly as above involve potentially dangerous pulling and pushing on the blood supply to the brain (carotid and vertebral arteries) as well as the brainstem itself, potentially causing dissection of the arteries. 2009 Sep;11(3):326-9. doi: 10.3171/2009.4.SPINE08689. This, usually due to trauma, but can also occur gradually due to certain autoimmune disorders such as rheumatoid arthritis, gross congenital hypermobility (such as Ehler Danlos syndrome or Marfan syndrome), or certain congenital syndromes such as Downs syndrome (Yang et al. AAI is less common in adults with Down syndrome. 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. 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. 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. 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. 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). I very often receive upright MRI reports where the rotation is completely normal, and the patient is still diagnosed with AAI. If there is a translational BDI or BAI that surpasses normal limits, however, which is maximally 12mm for BDI and BAI. Evaluation of the Cause of Internal Jugular Vein Obstruction on Head and Neck Contrast Enhanced 3D MR Angiography Using Contrast Enhanced Computed Tomography. 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. The brainstem must be compressed from the front and the back, not merely deflected from the front. Explore fellowships, residencies, internships and other educational opportunities. 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. The same applies for conservative strategies to reduce internal jugular vein compression. Acta Otolaryngol. #11760. Second, because it is such a controversial topic that lacks medical consensus, poor understanding of the actual mechanism of pathology leads to misunderstandings. Due to the instability in the craniocervical junction deformation can occur to the brainstem, upper spinal cord, and cerebellum. Instability in the hip can result in dislocation, ligament tears, muscle damage and wear of the joint. En este folleto, aprender sobre la IAA y cmo afecta a las personas con sndrome de Down. Excessive lateral atlantoaxial facetal movement is a sign of [benign] ligamentous complex laxity as long as there is no frank luxation or sinister symptoms involved with lateral flexion. This website uses cookies to improve your experience while you navigate through the website. DOI: https://doi.org/10.35975/apic.v24i1.1230. 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. Some top offenders may suggest full craniocervical fusion, ie. Get the latest news on COVID-19, the vaccine and care at Mass General. If there is no medullary compression, not even in a flexion/extension scan, then we cannot say that the patient is of surgical degree, even if it is very low, unless they look so bad that it is reasonable to expect frank compression in the near future! had been excluded by her primary care physicians and local hospital. And, of course, to determine whether or not the findings actually correlate with the patients symptoms and clinical exam. Sometimes flexion-extension and rotational imaging is necessary. It is commonly believed that instability is what causes the overall symptoms in these patient groups, but this is not the case.

This site complies with the HONcode standard for trustworthy health information: verify here. 10 things you should know about Cervical Disc Replacement. 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. If unavailable, a CT angiogram can be used, but is less sensitive. Either way, if positive, move on to confirm narrowing of the jugular passage between the styloid process and C1 transverse process on a CT scan. Clunking, clicking and pain in the upper neck. It is mandatory to procure user consent prior to running these cookies on your website. I see massive amounts of patients with alleged AAI who have normal atlantoaxial facetal overlap, and of course, also lacking clinical correlation. Patient resources for the Down Syndrome Program. 10 things you should know about Cervical Disc Replacement. 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. If there are no symptoms, then what reuslts are you talking about? 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. A positive test would be interpreted by unbearable head pressure, lightheadedness, worsening of headache, etc., within about 20-30 seconds. 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. Atlantoaxial instability | Cervical Fusion or Prolotherapy PRP Stem Cell treatment options Surgical treatments for Cervical Instability Disc, disc, disc may be wrong, wrong, wrong In Posture is done for the rest of your life. 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. What is atlanto-axial instability? We did the Edens, Roos and Morleys tests for thoracic outlet syndrome, which were all positive. About Radiologic spectrum of craniocervical distraction injuries. In late stages, even the CTV will show severe compression, and at this stage, surgery may be the best option for resolution if there is clinical correlation. Dashti SR, Nakaji P, Hu YC, Frei DF, Abla AA, Yao T, et al. Treatment depends on your son/daughters symptoms. 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. Ann Rheum Dis. Brainstem compression, when symptomatic, will usually cause quadriparesis along with phrenic nerve palsy. Although there were no current grounds for surgery? Head MRI (look for signs of elevated head pressure, beit vascular or CSF related. 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? This website uses cookies to improve your experience while you navigate through the website. Call us: 212.774.2837 As touched upon in the beginning of this article, that prompted me to write this article, is a huge massive influx of patients over the last few years who have been illegitimately diagnosed with AAI or CCI. PMID: 18708935. Spine (Phila Pa 1976). The atlantoaxial joint is normally stabilized by a projection off the axis called the dens, which fits into the atlas, as well as several ligaments between the two bones. There are two causes for the instability, trauma and birth abnormalities. Traumatic instability occurs after forceful flexion of the head, The success rate of this surgery is 80% or greater; however, there are many potential complications and a mortality rate of 5-10%. In most circumstances, even if there is poor overlap but no evidence of frank facetal luxations (clinical history or with provocation), then conservative therapy can usually prevail in management. 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.
