Since then, others, including Jen Brea and Julie Rehmeyer, have been diagnosed and undergone surgery, while others [] What Are the Long Term Effects of Untreated Whiplash? Your doctor is puzzled as all your tests are normal. [53] When cervical instability is present below C2, additional vertebrae may also be fused. [5] According to Brodbelt & Flint, however, an "increased range of joint movement, caused by ligamentous laxity, is not the same as spinal instability resulting from trauma or major inflammatory arthropathies such as (historically) rheumatoid arthritis. [citation needed][42] According to Henderson FC, ventral brainstem compression may exist in flexion of the cervical spine, but appear normal on routine imaging.[5], More than twenty radiological measurements have been proposed or used in the diagnosis of CCI. "Craniocervical Instability (CCI), also known as the Syndrome of Occipitoatlantialaxial Hypermobility, is a structural instability of the craniocervical junction which may lead to a pathological deformation of the brainstem, upper spinal cord, and cerebellum. 6 Bolognese, Paolo. Down syndrome : atlanto-occipital instability due to laxity of the alar ligament. A more common technique is the open reduction and fusion stabilization procedure. In the 2018 video at 1:06:45 Dr Bolognese say that CT scans can be used to detect rotational instability of the craniocervical joint. Neuroimaging They may be referred to together as a cervicomedullary syndrome and may include[15]: In addition to producing significant pain and neurological symptoms, the compression and kinking of the brain stem can cause significant injury to the brain stem neurons by stretching the axons of the nerves to the point that they break and recoil, producing what are called axon retraction bulbs that can be seen on microscopic examination of the cells. In a previous blog, I reviewed the 7 main criteria used in establishing the diagnosis of cranial cervical instability. If supine, a 3 Tesla MRI is preferred over a 1.5 Tesla. This can be associated with pain, crunching noises, or popping sensations and may. Craniocervical instability (CCI) occurs when the craniocervical junction at the base of the brainstem becomes 'shaky'. The diagnosis of CCI is based on symptom presentation, a supportive history, demonstrable neurological findings and abnormal imaging. Traumatic ligamentous ruptures or gradual deterioration of joint stability may cause basilar invagination, which is a degenerative process causing the odontoid process to graduall migrate into the head via the foramen magnum. The procedure is called Percutaneous Implantation of Cervical Ligaments (PICL) To learn more about this groundbreaking procedure please click on the video below.

To learn more about CCI please click on the video below. Cervical and thoracic instability and discopathy in EDS can lead to a loss of the normal cervical lordosis and myelopathy. The injured disc can compress or irritate one or more nerves resulting in arm pain at night. Rarely, some people with upper cervical disorders may experience a set of symptoms called vertebrobasilar ischemia, which occurs when a change in head position puts . Because ligaments are too weak, muscles tend to tense up in order to compensate, so they get exhausted. Gaining proper range of motion and reposition of upper cervical repositioning are necessary before training with movement control exercises. The constellation of symptoms caused by craniocervical instability has been labelled the cervico-medullary syndrome. Milhorat et al. 2018;4(1):109115. Injury that causes torn tissue in ligaments or skull supporting muscles. The purpose of this study was to investigate the influence AS has on various radiologic parameters used to detect traumatic and degenerative . What are the treatment options for arm pain at night? 3. Lying with the feet somewhat higher and head lower (Trendelenberg) allows gravity to work somewhat in the patient's favor. This is especially important considering that, according to Chiari expert Paolo Bolognese, M.D., [with revision surgeries], the results are not as good as if you had done the posterior decompression well the first time.[3]. This is a very helpful measurement for determining how much a retroflexed odontoid is compressing the brain stem. "Occipito-atlanto-axial Hypermobility: Clinical Features and Dynamic Analysis of Cranial Settling and Posterior Gliding of Occipital Condyle. A perpendicular line is then drawn from the center of this line to the dura of the brain stem. A craniocervical abnormality is suspected when patients have pain in the neck or occiput plus neurologic deficits referable to the lower brain stem, upper cervical spinal cord, or cerebellum. Craniocervical instability ( CCI) is a medical condition where there is excessive movement of the vertebrae at the atlanto-occipital joint and the atlanto-axial joint, that is, between the skull and the top two vertebrae ( C1 and C2 ). In the case of the craniocervical region, its understanding becomes even more challenging, since its anatomy and physiology are more complex and it is more mobile. Published 2018 Nov 28. doi:10.1002/lio2.227. Ehlers-Danlos Syndromes and Hypermobility Spectrum Disorders (hereditary) can progress to cause CCI. Sandwiched between the bones is a disc that functions as an important shock absorber. Using condylar screws may increase the risk of injury to major vessels, particularly in the hands of a less experienced surgeon. - Craniocervical instability - also called Cranial Cervical Instability, CCJ instability, and other terms. This is an x-ray examination that is recorded in which the patient is put through various movements including bending the neck forward, backward, and to the side. Craniocervical instability, if left untreated, can result in a progression in symptoms and injury to the cervical discs, facets, muscles, and nerves. Symptoms are frequently worsened by a Valsalva maneuver or by being upright for long periods of time. https://chiaribridges.org/glossary/symptoms-of-craniocervical-instability/, https://chiaribridges.org/glossary/symptoms-of-atlantoaxial-instability/. A neurologic syndrome following injury of the spinal sympathetic nerves of the neck. CCI is typically diagnosed via a cervical MRI, whether supine or upright.

Another cause of elevated heart rate is Postural Orthostatic Tachycardia Syndrome (POTS). Prolotherapy, including with stem cells, is another treatment option used,[12] but there is limited scientific evidence on this approach. However, in more severe cases, a further surgery called an odontoidectomy may be needed to remove the odontoid process. 16 Henderson, F C, et al. 2023 ICD-10-CM Range M00-M99. Why?

Henderson FCS, Francomano CA, Koby M, Tuchman K, Adcock J, Patel S (2019) Cervical medullary syndrome secondary to craniocervical instability and ventral brainstem compression in hereditary hypermobility connective tissue disorders: 5-year follow-up after craniocervical reduction, fusion, and stabilization. Cervicalgia is a medical term used to describe neck pain. Adv Otorhinolaryngol. Batzdorf U, Henderson F, Rigamonti D 2015. For example, headaches with dizziness may arise from tight or contracted neck muscles. A measurement of more than 12 mm also denotes instability. Lying supine eliminates the downward gravitational pull, reducing symptoms to some degree. Other important measurements involving ventral brain stem compression for a kyphotic clivo-axial angle and/or retroflexed odontoid include the Grabb-Oakes and Harris measurements. All the imaging studies are normal. See Figure 3. YouTube, American Syringomyelia Chiari Alliance Project, 16 Mar. Most of us have experienced rapid heart rates after vigorous exertion or exercise. Craniocervical Instability & Ehlers Danlos Syndrome: Know the Facts. In addition to cognitive impairments, many patients also report generalized mental fatigue making complex tasks almost impossible.

A detailed examination of stiff neck symptoms can determine the exact condition affecting the stiffness of ones neck. Cervical spondylosis is common, and discectomy and fusion may be necessary. A meta-study of 2274 procedures across 22 studies[53] found the following complication rates: Meta-studies place the rate of death from fusion surgery at 0-0.6%. Various specific surgical techniques are applied in craniocervical fusions. supine lying on the back or with the face upward. It is frequently co-morbid with atlanto-axial instability, Chiari malformation[1] and tethered cord syndrome. What Is the Alar Ligament? Act now before the symptoms and dysfunction progress. Fortunately, this condition is treatable, though not curable. [4][26], More recently, physicians have reported an increased prevalence of CCI in patients with hereditary connective tissue disorders.

The craniocervical junction is the area at the back of the skull which houses the brainstem, the cerebellum and the top of the spinal column. The reason that being upright is problematic is that gravity is allowing increased interaction between the brain stem and the top of the spinal column, increasing symptoms. The major ligaments involved are the Alar, Transverse and Accessory ligaments. In addition to pain, CCI can cause muscle spasms, neck stiffness and soreness, migraines, and vertigo. Measurement Techniques for Upper Cervical Spine Injuries: Consensus Statement of the Spine Trauma Study Group.Spine., U.S. National Library of Medicine, 1 Mar. 2015, . Patients with CCI can struggle with memory, concentration, and ability to complete tasks. This may be especially true in patients with cervical degenerative disease, such as ankylosing spondylitis (AS). Consequently, it only takes a slight alteration of our normal anatomy to cause injury to these delicate nervous tissues[16]. In a small case study of 20 patients, the five-year outcome of OCF was generally favorable with most patients experiencing symptom relief post-surgery. The result is that the bones that make up the lower skull and upper spine get pushed out of their normal anatomic location and begin to impinge on or cause stretching of these parts of the nervous system. [emailprotected] causing craniocervical instability. Visual disturbances can vary from mild to severe involving a number of symptoms. Common disc injuries include disc bulges, and herniations. 2. If the angle created is less than 135, it is considered pathological. Possible explanations include. There was, however, only a small increase in objective outcomes such as work resumption, with 60% of patients remaining unable to work or go to school. Motor vehicle accidents, contact sports, and forceful manipulations by chiropractors are the most common examples of trauma. Balance problems can be a significant issue (3). Conservative treatment of craniocervical instability includes physical therapy[10][11] and the use of a cervical collar to keep the neck stable. Patient-reported outcomes like questionnaires are not objectives. This is a debilitating headache that is constant in duration and miserable. Basilar Invagination and Basilar Impression are also often seen with instability. Forms of Basilar Invagination now include the prolapse of the odontoid process through the foramen magnum (the original condition described by the term), cranial settling, a kyphotic clivo-axial angle, and a retroflexed odontoid[12].
