For occipial neuralgia, an ultrasound guided nerve block will cure these symptoms for three hours and thus confirm the diagnosis. Moreover, tractioning the neck of these vulnerable patients can often cause undesirable effects. are generally useless in most cases? Global Spine J. (I will post the before- and after images when I return to Colombia in August, as they are on a separated hard drive). Then the patient can make an informed decision about whether or not they want to invest in experimental therapy. 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. This website uses cookies to improve your experience while you navigate through the website. Most dogs with AA instability will develop clinical signs within the first 2 years of life, often after a seemingly mild traumatic event. In most cases it is convenient to put bone graft, usually autologous, taken from the iliac crest or the patients own rib. It is advisable to obtain just a lateral view first. 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. In such cases I tell my patients that, yes, you do have mild AAI, but it is not causing your symptoms. 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. The exam should be done lying down, without a neck pillow. Surgery to address problems in this area can be risky. These cookies do not store any personal information. Moderator. It should be stressed that C1-C2 fusion, indicated by symptomatology, results in the natural cancellation of C1 over C2 movement so it results in approximately a deficit of 50% of the rotation of the neck. 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. 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). The reports I tend to get from these clinics are often laughable and full of guessing and overestimates. 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). Our surgeons provide a full range of treatments including non-surgical options as well as surgical repair. Why rely on Washington University experts for treatment of your atlantoaxial instability? Myran R, Kvistad KA, Nygaard OP, Andresen H, Folvik M, Zwart JA. We offer diagnostic and treatment options for common and complex medical conditions. 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. 2. The ligaments involved are the transverse, alar and capsular ligaments. 2008). I, personally, although I created my own manipulation protocol for this problem ALMOST NEVER use it. 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. Neurology. For treatment of the facetal dysfunction I recommend postural correction for the head neck and shoulder blades, along with exercises for the trapezius, levator scapulae, suboccipital and deep neck flexor muscles. 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!) The deep neck flexors should not engage as this lessens the compression. Surgical options, sometimes including relevant-level fusion, may be warranted in these circumstances. If someone has an ADI of 4.5mm, can this be treated via physical therapy, or is it too much instability? 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. First of all, studies have shown that FLAIR hyperintensities (suggestive of ligamentous partial rupture or damage) have been found in a lot of asymptomatic patients (Myran et al. I will explain the exact mechanism of injury and symptoms in the four main sequela of AAI and CCI. Thanks for your help! Second of all, if there is suggested ADI widening, but a high quality supine MRI with low slice thickness ascertains patency of the majority of the fibers of the TAL, the likelihood of actual complete rupture and future brainstem injury is extremely low. About Wake up and walking begins on the second day after surgery. 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. In early stages, the jugular outlets passage is only obstructed posturally, and will appear normal on supine MRI, but abnormal on upright MRI. Neurosurgery.

This is no longer true. This article will take a critical look at these diagnoses and elaborate upon the factual structural risks that are seen in atlantoaxial- and craniocervical instabilities, as well as their expected realistic symptoms and triggers. Patients with severe ligamentous compromise and a risk for actual dangerous secondary potentially pathologies, must have instability so aggressive that it can cause damage to the brainstem or adjacent cerebro-arterial supply. But opting out of some of these cookies may affect your browsing experience. Symptoms of VBI develop rapidly in patients with legitimate and adequate degrees of vertebral artery compression when placed in the triggering position. However, I also told her that she may end up having fixation surgery in the future to prevent foreseeable compressive damage to the brainstem. Li M, Gao X, Rajah GB, Liang J, Chen J, Yan F, et al. 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. PMID: 30805289; PMCID: PMC6383461. De Kleyn A, Nieuwenhuyse P. Schwindelanfalle und Nystagmus bei einer bestimmten Stellung des Kopfes. Traumatic Atlantoaxial Lateral Subluxation With Chronic Type II Odontoid Fracture: A Case Report. 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. doi: 10.1227/NEU.0b013e3182333859. Dynamic angiograms could also be applicable in certain circumstances, cf. 2020). ADI laxity is mainly caused by head and neck trauma, so as long as you avoid future collisions, it will probably not deteriorate. To schedule an appointment, call one of the offices, or book an appointment online. It is possible to do it with extension and rotation, etc., but it is usually not necessary. 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. Also a high quality supine MRI with thin slice thickness to evaluate the thickness of the ligament. J Bone Joint Surg Am. 14 Postoperative care advices following cervical disc herniation surgery, 4 Predictive factors of the results in Cervical Herniated Disc surgery. The atlantoaxial complex refers to the first two bones of the neck (C1,the atlas, and C2,the axis) as well as the associated collection of ligaments that connect the bones together and the blood vessels that travel through them to the brain. The brainstems were completely void of evidence for compression in both cases, and there was no evidence of signal changes (consistent with brainstem damage) on MRI. Does thoracic outlet syndrome cause cerebrovascular hyperperfusion? Ann Rheum Dis. Bow hunters syndrome revisited: 2 new cases and literature review of 124 cases. These cookies will be stored in your browser only with your consent. Often, by radiologist alone, based on sparsome imaging findings (eg., alar ligament T2 FLAIR hyperintensity or mild to moderate lateral facetal overhangs) and a lacking compatible clinical workup. Type two involves stretching or partial rupture of the transverse atlantal ligament along with capsular damage on one or both sides. When the bones or ligaments of the atlantoaxial complex are injured, the spinal cord is at particular risk for injury, and surgical treatment is often indicated. But this is rarely the case in my experience. Type three involves anterior subluxation of the entire atlas due to combined full rupture of the TAL and partial rupture of the capsules and other structures. 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? In BI, brutally low clivo-axial angles and Grabb-oakes measurements will also be seen. The mission of FORM Ortho is to be the preferred provider of orthopedic care and occupational health amongst our community, case managers and primary care physicians. A lot of things that cause temporary results are just placebo. DMX I dont recommend getting a DMX. nr. Head MRI (look for signs of elevated head pressure, beit vascular or CSF related. 3-Cranio-atlanto-axial instability, levels C0-C1-C2. Symptoms of brainstem compression are respiratory crisis and quadriplegia, but can also manifest more diffusely. I consulted with her and reviewed her imaging: The quality of the images, first and foremost, was very low. Merely feeling worse when standing up, even if indeed feeling awful, is not a strong indicator of AAI CCI As mentioned above, it is the influence of cervical positioning. 914 390 028 Second, because it is such a controversial topic that lacks medical consensus, poor understanding of the actual mechanism of pathology leads to misunderstandings. Dysautonomia when standing up is often related to craniovascular problems, whereas difficulty holding the head up suggests mumscular damage. A critical view on the overdiagnosis of AAI/CCI. Fielding JW, Hawkins RJ. All conventional things like heart and lung problems, MS, cancer, infections etc. Atlantoaxial instability (AAI) is the term for increased motion at the joint between the 1st and 2nd cervical vertebrae (the atlas and the axis). Let us help you navigate your in-person or virtual visit to Mass General. A CTV is preferable, but a general neck CT will also do if you have sensitive kidneys and would like to avoid contrast infusion. 2019) have documented numerous symptomatic cases of jugular vein stenosis at the craniovertebral junction. Dissection of the vertebral and carotid arteries is fairly rare and can be excluded through a doppler ultrasound or CT angiogram. Gweon HM, Chung TS, Suh SH. None of these tests would be able to reproduce her symptoms if they were stemming from AAI or CCI. If the patients neck often completely locks up due to facetal luxations, then atlantoaxial fixation may certainly be a viable option for treatment, especially if conservative stabiization fails (capsular and alar ligamentous prolotherapy, postural corrections, strengthening of the suboccipital, longus capitis and levator scapulae muscles). Patient resources for the Down Syndrome Program. Atlantoaxial malalignment is best visualized on a lateral view. 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. Specialist imaging research to help diagnosis. Atlanto-axial rotatory fixation. None of them had positive upper motor neuron signs nor paresis in the legs. I recommend doing this with a neuro-ophthalmologist, not a general ophthalmologist or opticician, as the findings are often missed. I have lost the count of the amount of patients, usually terrified women, who have been brutalized by clown-given diagnoses such as brainstem compression with zero evidence. 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). 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. Additionally, spinal instability in the form of spondylolisthesis A positive test would be interpreted by unbearable head pressure, lightheadedness, worsening of headache, etc., within about 20-30 seconds. 1977;59 (1): 37-44. This is not good medical practice. This would depend on whether or not the compression of the brainstem is constant, which again would depend on several factors. Or do you mean that there are positive improvement in symptoms despite the imaging being labeled as negative? The atlantoaxial instability may also have an acute traumatic origin, which may sometimes require urgent treatment, though in some cases it triggers development of the craniocervical or atlantoaxial instability. Flexion and extension imaging fails to demonstrate any sort of brainstem compression. 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. 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. 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. Seemingly unrelated, Higgins et al (2013) and others (Dashti et al 2012, Li et al. Copyright 2007-2023. This conformation may be associated with thickening of the interarcuate ligament (atlantoaxial band), which has been interpreted as an indicator for instability in the atlantoaxial joint [79]. Both measurements tend to worsen with neck extension. The atlanto-occipital joint allows your head to move up and down, while the atlantoaxial joint lets your head rotate. 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.

Atlas screws are generally placed in the lateral masses. Craniocervical Instability (CCI), also known as the Syndrome of Occipitoatlantialaxial Hypermobility. One patient was told by a famous alternative european neurosurgeon that she has CCI and AAI, and although there is no evidence for current surgery, she would probably be in a wheelchair within a few years and might even die. 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. It means that the instability is, or will probably, shortly, become bad enough to carry the potential to damage nerves or blood vessels. What muscles would need to be strengthened to prevent the ADI from opening up? At Dr Gilete we are experts in Ehlers Danlos surgery, craniocervical instability EDS,neuro and spine disorders related to EDS and whiplash. More information about surgical treatment. In BI, the compression tends to be constant. 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. J NS 2015, V8 issue 4. The dorsal lamina of the atlas shifts caudally and ventrally against the spinous process of the axis. We'll assume you're ok with this, but you can opt-out if you wish. Evaluation of the Cause of Internal Jugular Vein Obstruction on Head and Neck Contrast Enhanced 3D MR Angiography Using Contrast Enhanced Computed Tomography. Musa A, Farhan SA, Lee YP, Uribe B, Kiester PD. It is mandatory to procure user consent prior to running these cookies on your website. the basion-dens interval, is the distance between the tip of the clivus and tip of the C2. 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. 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). This is a major component in the workup for TOS CVH). Spinnato P, Zarantonello P, Guerri S, Barakat M, Carpenzano M, Vara G, Bartoloni A, Gasbarrini A, Molinari M, Tedesco G. Atlantoaxial rotatory subluxation/fixation and Grisels syndrome in children: clinical and radiological prognostic factors. Type D would generally involve a dens fracture as the atlas migrates posteriorly, along with facetal luxation and capsular rupture. Basil R. Besh, M.D. 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. Research has shown that normal limits are 3 and 10mm, with an absolutely maximum of 12mm (Ross & Moore 2015). 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. Our surgeons can discuss with you the various treatment options for your specific condition. 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. 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. Sometimes, an X-ray shows AAI when there are no symptoms. Must be carefully evaluated and correlated with the patients symptoms). Apr 2, 2022 Any experience of Atlantoaxial instability? Another patient was told by a well-known pain physician in the US that she had brainstem compression and required several expensive prolotherapy procedures. More commonly, however, a due to asymmetrical tearing of the covering ligaments, rotational subluxation or frank luxation is seen according to the Fielding & Hawking classifications (1977): Type 1, 2, 3 and 4, wherein types one and two are the most commonly encountered ones. , brutally low clivo-axial angles and Grabb-oakes measurements will also be applicable in atlantoaxial instability specialist circumstances, cf nerve block cure...
