This, however, is very rarely the case with this patient group in my experience. These cookies do not store any personal information. Booking Donald Corenman, MD, DC. These problems will mainly endanger the brainstem. Save my name, email, and website in this browser for the next time I comment. 2012). 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. Because it doesnt work most of the time, and doesnt cause any lasting results. 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). 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). Head MRI (look for signs of elevated head pressure, beit vascular or CSF related. 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. 3-Cranio-atlanto-axial instability, levels C0-C1-C2. Myran R, Kvistad KA, Nygaard OP, Andresen H, Folvik M, Zwart JA. 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. J Neurol Surg B. DOI: 10.1055/s-0039-1677706, Perez MA, Bialer OY, Bruce BB, Newman NJ, Biousse V. Primary Spontaneous Cerebrospinal Fluid Leaks andIdiopathic Intracranial Hypertension. 2014 Aug;4(3):197-210. doi: 10.1055/s-0034-1376371. Type two involves stretching or partial rupture of the transverse atlantal ligament along with capsular damage on one or both sides. The instability present between these vertebrae can cause the vertebrae to shift and injure the spinal cord. Neurology. November 19, 2014 at 8:19 pm. 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. If there are no symptoms, then what reuslts are you talking about? 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. Moreover, genuine cases of brainstem compression causes paralysis and other upper motor neuron signs, and will present with syringobulbia or compressive bulbopathy. 2020). 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. Strong evidence of clinical correlation must be present from a clinician that is familiar with the signs and triggers in upper cervical instability-cases. Because of its role in movement, it is, unfortunately, commonly injured. These problems are much more constant than AAI CCI, which are, for the most part, positional problems. We'll assume you're ok with this, but you can opt-out if you wish. Atlantoaxial rotatory subluxation Contact Dr. Gilete Our commitment to reliable health and medical information on the internet This site complies with the HONcode standard for trustworthy Common arguments for treatment may be claims that, although the MRI and even upright MRIs are normal, their own DMX scan is positive, or that the MRI, which was deemed normal by the local hospital, in reality shows signs of ruptured ligaments and that this fits with the patients symptoms. How is possible for them to have results when there is no symptomatic AAI/CCI? Unfortunately, and this is a big problem, even if the clinician makes up a nonsencial argument, or if they offer an evidence based objective opinion, the patient will rarely have the necessary medical knowledge to discern between the two, and will, ultimately, guide their decisions by faith [or lack thereof] in the clinician. to analyze our web traffic. Once in the Operating Room, surgery is performed under general anesthesia, with Neurophysiological monitoring (SSEP somatosensory evoked potentials), neuronavigation guidance and intraoperative fluoroscopy guidance. Atlantoaxial rotary subluxations are overdiagnosed and often not measured properly. What muscles would need to be strengthened to prevent the ADI from opening up? Diagnostic markers for occult craniovascular congestion. She was never evaluated for clinical correlation for these alleged findings, ie., no one evaluated if these findings had actual compatibility with her clinical symptoms and, especially, triggers. 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 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, Atlanto-axial instability (AAI) is a condition that affects the bones in the upper spine or neck under the base of the skull. Out of these, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. Uniondale, NY 11553. 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. When I reviewed both of these patients imaging and cases, the only findings were slightly low CXAs and a Grabb-Oakes around 9mm. Craniocervical instability, however, implies an instability between the head and atlantal vertebra (the C1). 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 TOS CVH the patient will generally feel better when stress is reduced along with taking beta blockers (confer with your doctor). This is not good medical practice. Clinical signs of such an injury include neck pain, weakness in all limbs, and potentially paralysis from the neck down and death. This website uses cookies to improve your experience. 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. AAI is less common in adults with Down syndrome. 2012 Mar;70(3):E795-9. 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). 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. Neurosurg Rev. 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). However, I also told her that she may end up having fixation surgery in the future to prevent foreseeable compressive damage to the brainstem. It mainly consists of the posterior fusion of the affected vertebrae, in this case, the atlas (C1) and the axis (C2). I recommend sticking to clinics that have good reputations and good imaging protocols. 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. This would depend on whether or not the compression of the brainstem is constant, which again would depend on several factors. Foramen magnum decompression or syrinx manipulation was not performed in any patient. 2021 Feb;180(2):441-447. doi: 10.1007/s00431-020-03836-9. TOS is often considered a mere upper limb nerve pathology, but this is not the case. Dashti SR, Nakaji P, Hu YC, Frei DF, Abla AA, Yao T, et al. 2014). Therefore before proposing surgery, the evaluation of each case must be done really carefully. The exam should be done lying down, without a neck pillow. As stated, although rooted in postural dysfunction, this is not really a problem of pathological instability, and therefore I dont recommend neck fusion to treat this problem. 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.

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. In previous epidemiologic studies, the prevalence of atlantoaxial instability in persons with Down syndrome was found to be between 9% and 31%. 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). The aim of surgery is to stabilize the AA joint internally to prevent future spinal cord injury. The ligaments holding the bones together can also be injured in trauma, or weakened in certain inflammatory conditions such as rheumatoid arthritis or Downsyndrome. 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 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. Upright MRI has very low quality and because of this, there is a lot of guesswork involved in its interpretation. It is crucial to understand that the general minor instabilities involved in AAI and CCI are not the cause of symptoms. She had been out from work for one year at the point of consultation, but her doctors could not find anything wrong with her. 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. Moreover, tractioning the neck of these vulnerable patients can often cause undesirable effects. Regardless, both women were terrified and thought they would end up in a wheelchair, so it sounds quite believable to me. My experience is that most of these patients suffer from craniovascular pathologies, not CCI and AAI. Both neurophysiological monitoring and neuronavigation guidance are safety measures for the patient. Dissection of the vertebral and carotid arteries is fairly rare and can be excluded through a doppler ultrasound or CT angiogram. 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. In my experience, we would expect to see at least 20mmHg maximum venous pressures. The success rate of this surgery is 80% or greater; however, there are many potential complications and a mortality rate of 5-10%. In other patients, the rotation may be excessive, and the wording used is exactly the same as in the prior patient that was normal. (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. Yang SY, Boniello AJ, Poorman CE, Chang AL, Wang S, Passias PG. The findings may be quite subtle and are easy to miss outside of dynamic exams. Josy GF, Daily AT. It is mandatory to procure user consent prior to running these cookies on your website. Although there were no current grounds for surgery? Powers ratio will be abnormal in cases of both BI and craniocervical dissociation (Ross & Moore, 2015). The dorsal lamina of the atlas shifts caudally and ventrally against the spinous process of the axis. Horizontal misalignment of the facet joints often cause dorsal migration of the C0 and C1 facets which cause approximation of the styloid process and the C1 transverse processes. 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. Adapted from Problems with the upper spine in children and adults with Down syndrome (DS) by E. Margolis, B. Henry, B. Sandella and M. Stephens. 2011, Dashti et al. 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. PMID: 30805289; PMCID: PMC6383461. Kjetil Larsen is a Researcher and a injury rehabilitation specialist, and is the owner of MSK Neurology. 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. 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. The problem, in the patients eyes, may be a lacking reasonable counter-argument and counter-diagnosis that would explain his or her symptoms, which then prompts the patient to seek out alternative health care. The joint between the upper Evaluation of the Cause of Internal Jugular Vein Obstruction on Head and Neck Contrast Enhanced 3D MR Angiography Using Contrast Enhanced Computed Tomography. Must be carefully evaluated and correlated with the patients symptoms). 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. In many circumstances, conservative treatment (Larsen 2018, atlas joint article as linked earlier) is appropriate. KL TRENING & REHAB This website uses cookies to improve your experience. PMID: 25210334; PMCID: PMC4158632. I am not saying it is easy. Articles Or do you mean that there are positive improvement in symptoms despite the imaging being labeled as negative? 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 General Hospital Corporation. Our surgeons can discuss with you the various treatment options for your specific condition. 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. 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. It is not a substitute for medical advice and should not be used to treatment of any medical conditions. 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. 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). 3. 2015. Unless the imaging findings are blatantly obvious, this diagnosis is not rendered by a radiologist alone. See my youtube channel for appropriate training. At Mass General, the brightest minds in medicine collaborate on behalf of our patients to bridge innovation science with state-of-the-art clinical medicine. The patient will hinge back at their neck while simultaneously flexing the cranium. This may cause the patient to become afraid and to google their symptoms, which in and by itself is reasonable enough. Posture is done for the rest of your life. 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. I prefer to compare mid-jugular to the highest pressure found, usually in the torcula or SSS. If it is, however then flexion/extension and rotational imaging to exclude positional facetal luxation is warranted. Sometimes, an X-ray shows AAI when there are no symptoms. Ross & Moore. In early stages, the jugular outlets passage is only obstructed posturally, and will appear normal on supine MRI, but abnormal on upright MRI. Another patient was told by a well-known pain physician in the US that she had brainstem compression and required several expensive prolotherapy procedures. One or 2 out of every 100 children with Down syndrome have symptoms of AAI, but doctors do not know the exact number yet. Explore fellowships, residencies, internships and other educational opportunities. Headaches certainly can develop from instability of C1-2. Yang SY, Boniello AJ, Poorman CE, Chang AL, Wang S, Passias PG. Instability in the hip can result in dislocation, ligament tears, muscle damage and wear of the joint. Rev. It means that the instability is, or will probably, shortly, become bad enough to carry the potential to damage nerves or blood vessels. In such a case, to avoid foreseeable medullary damage, one may reasonably opt for fusion as preventative surgery, because the medulla, once damaged, does not always recovery after surgery. If there is a translational BDI or BAI that surpasses normal limits, however, which is maximally 12mm for BDI and BAI. In other words, the vertical distance between the head and the spine. This increased mobility causes headache and cervical pain as well as signs of compression of adjacent neural elements that form cervicomedullary syndrome. This site complies with the HONcode standard for trustworthy health information: verify here. Thus, I recommend the following studies for craniovenous hypertension and TOS CVH: Craniovasculo-hypertensive disorders (mainly IIH, TOS CVH (!) Deliganis AV, Baxter AB, Hanson JA, et al. Search for condition information or for a specific treatment program. 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. Her symptoms, however, did not at all change when changing her neck position and she had never had torticollis. This category only includes cookies that ensures basic functionalities and security features of the website. the section on bow hunters syndrome. Presuming the central venous pressure being normal, then I am not so interested in the pre and post-stenotic gradients as they tend to be unreliable. Dynamic angiograms could also be applicable in certain circumstances, cf. Li M, Gao X, Rajah GB, Liang J, Chen J, Yan F, et al. 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). 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). Org. But this is rarely the case in my experience. The bones are susceptible to fracture from high-energy impact such as falls or car accidents, especially in the elderly. Your email address will not be published. Patient resources for the Down Syndrome Program. This is really more of a poor posture/misalignment problem than a case of instability (Larsen 2018), but because it is a legitimate upper cervical problem then I will still mention it in this article. And, of course, to determine whether or not the findings actually correlate with the patients symptoms and clinical exam. 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. 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.
