"[5], It is not unusual for CCI to co-occur with other structural neurological abnormalities such as atlantoaxial instability (AAI) and chiari malformation (CM).[41][14]. Tags. Batzdorf U, Henderson F, Rigamonti D 2015. BMC Musculoskelet Disord. Thompson-Harvey A, Hain TC. 12 Kim, Louis J., et al. Additionally, the doctor can help you understand what to expect when . I have been a patient with severe pain and know firsthand the limitations of traditional orthopedic surgery. We use advanced imaging and treatment options to diagnose and manage your condition. An uncovering of the facets that exceeds 20% is considered pathological. Craniocervical instability is common amongst hypermobile connective disorders such as Ehler Danlos Syndrome (EDS) that affects up to 1% of the population. The authors discovered that many of these patients suffered from EDS and had other structural abnormalities at the upper spine such as CCI and cranial settling. Because of this, these vertebrae lack the same amount of stability as the remainder of the spine, and ligaments are largely responsible for their stability[8]. Craniocervical instability is a . Altered head-neck awareness and oculomotor disturbances are addressed prior to the introduction of training neck movement control. The clivus is a wedge-shaped bone that normally lies above and ventral to the top of spine. Common Craniocervical Instability symptoms include: A constant to near-constant head pain that can be described as feeling like the head is too heavy for the neck to support. It is a common finding in individuals affected by Ehlers-Danlos syndrome. In Co-morbidities that complicate the treatment and outcomes of Chiari malformation. Patients with CCI can struggle with memory, concentration, and ability to complete tasks. Even worse is it does not resolve over time. Some have raised concerns about CCI surgery in patients with ME/CFS given the lack of research on OCF in this patient population.[68]. When a patient has an injury of the cervical spine for quite a long time and/or in cases of Connective Tissue Disorders, conservative treatment may be not sufficient. Although the dura is opened to partially resect the tonsils, a duraplasty is not done. Complex Posterior Fossa revisions. It affects around one in 15 patients with Ehlers-Danlos Syndrome (EDS). Manual traction, halo and invasive cervical traction may be used to aid in the diagnosis of CCI. The procedure is very demanding and only performed at the Centeno-Schultz Clinic in Broomfield Colorado. supine lying on the back or with the face upward. Craniocervical junction abnormalities are congenital or acquired abnormalities of the occipital bone, foramen magnum, or first two cervical vertebrae that decrease the space for the lower brain stem and cervical cord. What are the causes? These ligaments include the alar, transverse, accessory, apical dens, and others. objective outcome An outcome of a clinical trial that is independent of the judgement of opinion of the assessor/clinician, e.g. Craniocervical Instability (CCI) is a medical condition where the strong ligaments that hold your head to your upper neck are loose or lax (1). Various specific surgical techniques are applied in craniocervical fusions. The kyphotic clivo-axial angle is an important and relatively easy measurement to indicate potential deformative stress on the brain stem. Cervicalgia is the 4th major cause of disability. Advantages of this procedure include a smaller incision, smaller hardware, less bone removal, and a thicker bone for which to insert screws in the occiput. A newer technique adapted by Dr. Paolo Bolognese is using a less invasive Chiari decompression surgery known as MIST (minimally invasive subpial tonsillectomy) along with a fusion using screws placed in the occipital condyles. Treatment of Craniocervical Instability typically begins with more conservative medical management, such as neck bracing, activity limitation, physical therapy (including isometrics, sagittal balance, core strengthening and cardio), and pain management. Like instability, a kyphotic clivoaxial angle is often seen in patients with connective tissue disorders and, A heavy headache (often referred to as feeling like a bobblehead or feeling like the head is a bowling ball), A Chiari-type pressure headache aggravated by, Facial pain or numbness Occasionally, including, Vision problems, including double vision and downward, In more severe cases, non-epiform seizures have also been documented. Understanding what signs and symptoms to look for that may indicate that your Chiari is more complex, is vital in receiving the appropriate treatment the first time. Its main known functions are the coordination of unconscious muscle movements and the maintenance of body positional equilibrium. followed-up on patients with Chiari malformation who did not improve with treatment and surgery. For these patients, Cervical Fusion is a major surgery that involves joining one or more of the spinal bones together using screws, bolts, and plates (1). It is important to note that ventral brain stem compression may not be seen on traditional supine MR imaging, while it may be very evident on dynamic imaging. 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. These cases usually involve the presence of a genetic connective tissue disorder and are thought by experts to be the cause of most Chiari decompression failures[2]. [53] Screw and rod fixation methods have lower complication rates and higher rates of successful fusion. - Craniocervical instability - also called Cranial Cervical Instability, CCJ instability, and other terms. What Are the Long Term Effects of Untreated Whiplash? The objective is to examine patient-reported outcomes in patients with Ehlers-Danlos Syndrome and Hypermobility Spectrum Disorder with craniocervical instability. For our purposes, this distinction is less important, but we will discuss any displacement in terms of Basilar Invagination, or BI for short. Interestingly, during the flexion of the normal spine, it stretches 17% of its length. [52] Although, in most cases these offer little relief. I quit a successful career in anesthesia and traditional pain management to pursue and advance the use of PRP and bone marrow concentrate for common orthopedic conditions. [14], The complications of OCF can be serious[55] and occur in an estimated 7% to 33% of patients. This is chronic fatigue, and it is one of the common symptoms associated with craniocervical instability. Case-based review 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. Digital Motion X-ray is considered the most accurate method. To learn more about CCI please click on the video below. Ehlers-Danlos Society Annual Conference 2015, 14 Aug. 2015, Baltimore, . 1.Offiah CE, Day E. The craniocervical junction: embryology, anatomy, biomechanics and imaging in blunt trauma. Another cause of elevated heart rate is Postural Orthostatic Tachycardia Syndrome (POTS). If non-invasive treatments for CCIfail to work, occipito-cervical fusion (OCF) can be considered. Diagnosis and treatment. If you or a loved one sustained an injury and have symptoms that include headache, dizziness, and brain fog which is unresponsive to conservative care you may have cranial cervical instability. Read here to learn the symptoms, diagnosis, and treatment options. Therefore, ligamentous laxity, as seen in connective tissue disorders, make these areas of the spine particularly prone to pathologic instability. The procedure allows patients to avoid the serious risks and complications associated with surgery. Cervical spinal fusion is performed on patients with more severe symptoms. This results in excruciating pain close to your neck, skull, and shoulders. Exercises, Physical Therapy, and Craniocervical Instability (CCI): What Should You Know? Symptoms can include cognitive impairments, muscle pain, trouble remaining upright (orthostatic intolerance), sleep abnormalities, and gastro-intestinal impairments, and others. 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 ). "Occipito-atlanto-axial Hypermobility: Clinical Features and Dynamic Analysis of Cranial Settling and Posterior Gliding of Occipital Condyle. "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. As CCI can lead to a compression of the brainstem, a number of experts believe it contributes to autonomic symptoms such as orthostatic tachycardia, dizziness and pre-/syncope that are frequently seen in patients with Ehlers Danlos Syndromes (EDS). The level of disability is important in diagnosing craniocervical instability (CCI). PEM may be referred to as a "crash" or "collapse" and can last for days or weeks. White III, Manohar M. Panjabi, et al. Using condylar screws may increase the risk of injury to major vessels, particularly in the hands of a less experienced surgeon. 1.Offiah CE, Day E. The craniocervical junction: embryology, anatomy, biomechanics and imaging in blunt trauma. The common symptoms of CCI can also arise from different clinical conditions. 3, Sept. 1997, . Pt I The Spinal Series, Jennifer Breas Amazing ME/CFS Recovering Story: the Spinal Series Pt. This procedure involves stabilizing the head with screws, making an incision that exposes the occiput through C2, and fixing plates to the occiput which attach to the C1 and C2 (and sometimes C3) vertebrae with rods. Jeff Wood's remarkable recovery from severe ME/CFS following spinal surgery to correct craniocervical instability (CCI) and other problems shocked the ME/CFS community. Unfortunately for some individuals, the ringing in the ears is not due to an external event. 2013, . 2017;8(1):2947.
