It is advisable to obtain just a lateral view first. 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. Kjetil Larsen is a Researcher and a injury rehabilitation specialist, and is the owner of MSK Neurology. 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. Our surgeons can discuss with you the various treatment options for your specific condition. Last Update [site_last_modified date_format=Y-m-d H:i:s]. Beware that suboccipital pain, espeically if your imaging is normal, is a very common sympton in thoracic outlet syndrome, and is actually a migraine variant. 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. E7. This is no longer true. 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. Powers ratio will be abnormal in cases of both BI and craniocervical dissociation (Ross & Moore, 2015). Dysautonomia when standing up is often related to craniovascular problems, whereas difficulty holding the head up suggests mumscular damage. 1963;13(5):386396. We also use third-party cookies that help us analyze and understand how you use this website. Supine cervical MRI including T2-w sagittal-oblique sequences at 2mm slice thickness (disc and foraminal health is best evaluated on a supine MRI). 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). 404-256-2633. With the increasing dependence on smartphones, computers, and other devices in our modern Styloidogenic jugular venous compression syndrome: diagnosis and treatment: case report. 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. Styloidectomy and Venous Stenting for Treatment of Styloid-Induced Internal Jugular Vein Stenosis: A Case Report and Literature Review. Copyright Dr Gilete Neurosurgery & Spine Surgery. How is possible for them to have results when there is no symptomatic AAI/CCI? 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. In previous years, doctors thought all people with Down syndrome should have regular X-rays to check for AAI. https://doi.org/10.13104/jksmrm.2011.15.1.41. Required fields are marked *. This would depend on whether or not the compression of the brainstem is constant, which again would depend on several factors. Epub 2014 May 22. Symptoms of VBI develop rapidly in patients with legitimate and adequate degrees of vertebral artery compression when placed in the triggering position. Atlanto-axial rotatory fixation. We use cookies and other tools to enhance your experience on our website and ), induction of symptoms (all or nearly all of your symptoms, not some neck pain) with maximal rotation, nor during flexion or extension. ARTICLE IN PROGRESS The piece is virtually finished, but I am missing some imaging that I dont have access to here while I am on vacation in Norway. This category only includes cookies that ensures basic functionalities and security features of the website. In moderate stages, the MRI will appear abnormal, but the CTV will still appear relatively OK (because the patient tends to be placed on a neck wedge which protracts the head in the CT machine this reduces the compression). The atlantoaxial segment consists of the atlas (C1) and axis (C2) and forms a complex transitional structure bridging the occiput and cervical spine. I diagnosed her with mild (benign) atlantoaxial instability and TOS CVH. Copyright 2007-2023. 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. Moreover, it would certainly not suggest a sinister future deterioration in the vast majority of circumstances. 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. 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. (I will post the before- and after images when I return to Colombia in August, as they are on a separated hard drive). 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. Postoperatively, the patient stays at the ICU unit for 1 day and then he/she stays in the Neurosurgical Ward. Neurology. Moderator. 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. Mild to moderate cases tend to respond well to appropriate conservative therapy (not general therapy), cf., once again, my atlas joint article from 2017 linked several times earlier. Thus we control the spinal cord and nerves (cranial and cervical) in order to avoid potential damages to these important structures. 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. 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 this measurement in and by itself, when it is 9 or 10 or even higher, but there is no brainstem compression not even in flexion-extension imaging this cannot be interpreted as a surgical indicator. Maybe they temporary fix some compression? DMX. 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. Then, if there are not even sufficient findings for surgery, how can one possibly give such a fatal prognosis? 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). 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. 2014 Apr;5(2):59-64. doi: 10.4103/0974-8237.139199. This is Bow hunters syndrome, and may be caused by legitimate atlantoaxial instability. Fielding JW, Hawkins RJ. Postoperative hospital stay is usually around 7 days. Rather, just like with the CXA, it is an indication of the present spinal health status and perhaps also an indicator as to non-surgical prognosis as well as an indicator of likely outcome if nothing is done. In addition to that we would start treatment for thoracic outlet syndrome. More information about surgical treatment. PMID: 33064218. Now, it is true that specialty diagnoses can be missed by local generalists. For occipial neuralgia, an ultrasound guided nerve block will cure these symptoms for three hours and thus confirm the diagnosis. 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. 2014). Early stage) and constant compression (if seen on mri, moderate, if seen on CT, severe) of these structures may occur. She was also said to have ventral brainstem compression, which particularly scared her due to her difficulties with respiration. But this is rarely the case in my experience. Look for jugular vein compression, dural sinus and neck vein integrity, exclude typical patholgies such as aneurysms etc., exclude vertebral or carotid dissections, evaluate the thoracic outlet for interscalene, costoclavicular or subpectoral stenosis), Doppler of the carotid and vertebral arteries (look for signs of hypertension, cf. 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. I recommend doing this with a neuro-ophthalmologist, not a general ophthalmologist or opticician, as the findings are often missed. Surgical management is recommended for those with severe signs and for those who have tried and failed medical management. If the latter, could be JOS obstruction, or could be placebo. Atlantoaxial instability is an uncommon condition of dogs in which there is abnormal movement in the neck, between the atlas (first cervical vertebra) and axis (second vertebra). 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 BDI was 6mm and the BAI was 8mm, which are all farily normal. 2012). JRSM Short Rep. 2013 Nov 21;4(12):2042533313507920. doi: 10.1177/2042533313507920. This site complies with the HONcode standard for trustworthy health information: verify here. It is, as we say, in tangent with the dens and tectoral ventrally alone. See my other articles or YouTube videos for howtos. 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). Clunking, clicking and pain in the upper neck. 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. Another patient was told by a well-known pain physician in the US that she had brainstem compression and required several expensive prolotherapy procedures. 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. 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. Otolaryngology Case Reports Volume 16, September 2020, 100201, Larsen K, Galluccio FC, Chand SK. Some top offenders may suggest full craniocervical fusion, ie. My poor baby has become completely lame and incontinent in the last 48 hours. Musa et al. (Fixed rotatory subluxation of the atlanto-axial joint). Because it doesnt work most of the time, and doesnt cause any lasting results. This website uses cookies to improve your experience while you navigate through the website. Suboccipital symptoms that occur only with cracking, if the MRI shows arthritis or joint effusion, especially if the neck locks in rotary fixation, then this could be a case of legitimate AAI or CCI. The joint between the upper spine and base of the skull is called the atlanto-axial joint. Spine (Phila Pa 1976). The doctor will tell you which sports and activities are safe for your son/daughter. The ligaments involved are the transverse, alar and capsular ligaments. If its caused by rotation (rare), manipulation may temporarily improve jugular outlet passage, but it will not last. 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. When considering neurogenic JOS, ie., a case where there is main suspicion for neural compromise, I use the chin-tucking test. Atlantoaxial and craniocervical instability are both real and potentially sinister diagnoses that require treatment. Another common belief is that this mild deflection stretches the brainstem and somehow causes damage. Radiologic spectrum of craniocervical distraction injuries. This will be predominantly evident on a flexion/extension scan, where the basion-dens interval (BDI) will be dynamically increased, and greater than 10-12mm (Ross & Moore, 2015; Deliganis et al. Abbreviations: BDI: basion dens interval, CXA: clivo axial angle, BAI: basion-axial interval, ADI: Atlantoaxial interval. Please understand that no matter how bad you feel, pursuing the wrong diagnosis will not help. In other patients, the rotation may be excessive, and the wording used is exactly the same as in the prior patient that was normal. And, fair enough, I do not expect blind trust nor compliance. Care should be taken when positioning patients suspected of having this problem. J NS 2015, V8 issue 4. An X-ray is low-cost and low-risk, but it does not always tell whether a person has AAI or not. Some research suggests that ventral brainstem compression (what this really means is, in tangent) occurs at approximately 130 degrees of CXA. 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. More information about surgical treatment. Magnetic resonance imaging assessment of the alar ligaments in whiplash injuries: a case-control study. This increased mobility causes headache and cervical pain as well as signs of compression of adjacent neural elements that form cervicomedullary syndrome. The report claimed that there were signs of ligamentous rupture and bidirectional subluxation upon rotation in the atlantoaxial joints. 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. 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). The atlantoaxial complex is primarily responsible forenabling the head to rotate, or turn to the left and right, while also protecting the spinal cord from injury. Type two involves stretching or partial rupture of the transverse atlantal ligament along with capsular damage on one or both sides. A review of the diagnosis and treatment of atlantoaxial dislocations. 14 Postoperative care advices following cervical disc herniation surgery, 4 Predictive factors of the results in Cervical Herniated Disc surgery. 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. Headaches certainly can develop from instability of C1-2. 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. For TOS CVH the patient will generally feel better when stress is reduced along with taking beta blockers (confer with your doctor). 3-Cranio-atlanto-axial instability, levels C0-C1-C2. 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 people with Down syndrome, the ligaments (connections between muscles) are lax or floppy. Global Spine J. 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. This, again, prompted the more than 1000 euro consultation with the upright imaging center in a large european country. 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. Both positional (ie., upright. Rev. The bones are susceptible to fracture from high-energy impact such as falls or car accidents, especially in the elderly. If there are no symptoms, then what reuslts are you talking about? 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. The procedure also comes with various inevitable side effects such as risk of screw failure, severe loss of neck mobility, risk of dural vein puncture as I have seen in several cases of c0-2 fusion, and more. In BI, the compression tends to be constant. Neurosurgery. 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. 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. This can result in AAI where the bones are less stable and can damage the spinal cord. Tambin conocer las causas, los signos y los sntomas de la IAA. Both measurements tend to worsen with neck extension. If you have an atlanto-dens interval (ADI) of 5mm or greater, you have instability by definition. 2008). 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. TOS is also a common cause of dyspnea (respiratory difficulty), although these patients will have normal blood oxygen levels, which was also the case here. 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. 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. 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. Atlas screws are generally placed in the lateral masses. 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. Flexion-extension and cervical rotation on both sides should be evaluated. Seemingly unrelated, Higgins et al (2013) and others (Dashti et al 2012, Li et al. Symptoms of brainstem compression are respiratory crisis and quadriplegia, but can also manifest more diffusely. Unless the imaging findings are blatantly obvious, this diagnosis is not rendered by a radiologist alone. However, can we say the same if there is major guesswork involved in the rendering of the diagnosis? 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. This can be a blessing if one proceeds to be properly diagnosed based on objective criteria, but often extremely expensive and also dangerous, if not. Exam for bow hunters syndrome is done dynamically, but thats aother exam. 1. 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. We examined 404 patients with this chromosome disorder and observed their atlanto-dens intervals and spinal canal widths to be significantly different from children without Down syndrome. Booking Often times if surgery is required, the bones between C1 and C2 are fused together, requiring less than 48 hours of an in-hospital stay. 2000). A patient with positional brainstem compression due to TAL rupture, for example, will develop neurological (ie. Patients with normal structural alignment and more or less normal or completely normal radiological imaging, without clinical correlation, end up diagnosed with CCI or AAI due to a slightly low (non-sinister) CXA, say 135 degrees, and some signal changes in the alar ligaments on T2 FLAIR imaging or slight increase in the atlantodental interval (ADI) despite normal thickness of the transverse atlantal ligament (TAL). There are no exercises that can help an instability like that. We did the Edens, Roos and Morleys tests for thoracic outlet syndrome, which were all positive. Copyright Dr Gilete Neurosurgery & Spine Surgery. zen , nal , Avcu S. Flow volumes of internal jugular veins are significantly reduced in patients with cerebral venous sinus thrombosis. 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, These cookies do not store any personal information. The ligaments holding the bones together can also be injured in trauma, or weakened in certain inflammatory conditions such as rheumatoid arthritis or Downsyndrome. My experience is that most of these patients suffer from craniovascular pathologies, not CCI and AAI. 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. (2019) documented another case where a patient with RA developed odontoid fracture and subsequent anterolateral subluxation of the atlantoaxial joint. Request Appointment. Patients with rotary subluxation will develop torticollis and will generally appear fixed/rigid upon physical exam and may not be able to rotate their necks at all. And, she still had the same symptoms! Would need a flexion extension MRI and correlate to the patients symptoms. Wake up and walking begins on the second day after surgery. Gweon HM, Chung TS, Suh SH. 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). We'll assume you're ok with this, but you can opt-out if you wish.
