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. 3. Remember how your heart was rapidly beating after wind sprints or chasing after your dog who jumped the fence? Many describe feeling like they have a bobble-head. Neck stiffness can occur at the base of the head, down to the shoulders. 3, Sept. 1997,

The light was red and the traffic was stopped. Young RM, Sherman JH, Wind JJ, Litvack Z, O'Brien J. 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. It is more common in people with a connective tissue disease, notably Ehlers-Danlos Syndrome,[2] osteogenesis imperfecta and rheumatoid arthritis. Elevated heart rate may occur as the vagus nerve gets irritated by the extra motion in the upper neck. It is characterized by slow thinking, difficulty focusing, confusion, lack of concentration, forgetfulness, or haziness in thought. The major ligaments involved are the Alar, Transverse and Accessory ligaments. 2014 Aug;21(2):239-48. doi: 10.3171/2014.3.SPINE13684. tachycardia An unusually rapid heart beat. I am a co-founder of the Centeno-Schultz Clinic which was established in 2005. Being active is a central part of my life as I enjoy time skiing, biking, hiking, sailing with my family and 9 grandchildren. Cranial Cervical Instability (CCI) is a medical condition where the strong ligaments that hold your head to your upper neck are loose or lax. Down syndrome : atlanto-occipital instability due to laxity of the alar ligament. "[27], Some of the measurement ranges in the above table are also to be found in the 2nd International CSF Dynamics Symposium Consensus Statement (2013).[43]. The doctor you consult can evaluate your condition and help you determine if the surgery was successful. The information provided at this site is not intended to diagnose or treat any illness.From MEpedia, a crowd-sourced encyclopedia of ME and CFS science and history. Insights Imaging. Lying supine can bring short-term relief. This is not your normal headache caused by your in-laws or excessive consumption of alcohol. [3] It can be brought on by a trauma, frequently whiplash; laxity of the ligaments surrounding the joint; or other damage to the surrounding connective tissue. Various specific surgical techniques are applied in craniocervical fusions. This is a debilitating headache that is constant in duration and miserable. GI problems can be due to structural and functional problems within the gut itself. [14], The complications of OCF can be serious[55] and occur in an estimated 7% to 33% of patients. Craniocervical instability is common amongst hypermobile connective disorders such as Ehler Danlos Syndrome (EDS) that affects up to 1% of the population. 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. Craniocervical Instability (CCI) also known as Syndrome of Occipitoatlantialaxial Hypermobility, is a potential complication that people with EDS (and other connective tissue disorders) can experience. 2 Bolognese, Paolo A. postural orthostatic tachycardia syndrome (POTS) - A form of orthostatic intolerance where the cardinal symptom is excessive tachycardia due to changing position (e.g. This distance should not be more than 12 mm. [4][54][3][56][53] Common complications include screw failure, wound infection, dural tear and cerebrospinal fluid leakage[3] In some cases revision surgery is needed to treat infection or to remove hardware. The Alar ligament connects the upper neck to your head. For example, headaches with dizziness may arise from tight or contracted neck muscles. Conservative treatment of craniocervical instability includes physical therapy[10][11] and the use of a cervical collar to keep the neck stable. There is a right and a left Alar ligament which is illustrated to the right. Adv Otorhinolaryngol. Other experimental treatments for CCI include prolotherapy and stem cell therapy. 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. In severe cases of CCI, patients are confined to their homes and are socially isolated. Dr. Fraser Henderson presents the results a five-year follow-up study. This can be extremely frustrating. The procedure is very demanding and only performed at the Centeno-Schultz Clinic in Broomfield Colorado. 2016;17(1):441. Craniocervical junction disorders are abnormalities of the bones at the base of the skull and top of the spine. Diagnosis and treatment. Special radiographic studies are required which include upper cervical MRI or rotatory CT scan. The upper neck provides a position sense that has to be coordinated with balance information from the eyes and inner ear. 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. [2] These ligaments include the alar, transverse, accessory, apical dens, 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). It frequently co-occurs with atlantoaxial instability (AAI). Pain and discomfort can be debilitating. Balance disturbances vary in severity and can make a simple walk down the hall almost impossible at times. CCI is often used to refer to the commonly seen combination of issues with the craniocervical junction, that include the instability of the joints where the skull meets the C1 vertebrae (which is true CCI), the instability of the joints between C1 and C2 (true AAI), a retroflexed odontoid, pannus formation, and a kyphotic clivo-axial angle (which are all forms of basilar impression/invagination). MR documented craniocervical ligamentous injury at age 18 months: delayed formation of OS odontoideum. The 7 most common symptoms are a painful heavy head, headache, rapid heart rate, brain fog, neck pain, visual problems, and dizziness. https://chiaribridges.org/glossary/symptoms-of-craniocervical-instability/, https://chiaribridges.org/glossary/symptoms-of-atlantoaxial-instability/. [66][67] They speculate that mechanical compression of the brainstem due to CCI, or other underlying structural conditions, have the potential to cause characteristic ME/CFS symptoms such as post-exertional malaise, although there have not been any studies regarding this particular theory. 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. 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. How is cervicalgia diagnosed? They are almost identical to one another, and refer to upward displacement of the bones of the spine. Neurosurg Rev 42:915-936. Can be caused by exercise or illness. PT, massage, and medications did not help. Additionally, spinal instability in the form of spondylolisthesis was reported in 10% of patients. Hence the bones in the neck are C1 through C7. 303-429-6448 "[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]. supine lying on the back or with the face upward. For example, in Craniocervical Instability, the neck is not strong enough to support the normal weight of the head, without elements of the spine moving in such a way that it causes pain or damage to the nervous system (spinal cord, brain stem, and even cranial nerves). speculated that the resulting compression of the brainstem might be the cause of the autonomic and other symptoms these patients were suffering from. The ideal tests to diagnose CCI and AAI are an upright MRI with flexion and extension and a 3D CT with rotational views, respectively[10]. According to a 2013 consensus statement on the assessment of CCI, a CXA of 135 degrees or less should be considered as "potentially pathological. Surgeons and patients alike should consider surgery after medical management has been maximized and the patient has shown a positive response to neck bracing[10]. Later these 20 measurements got reduced to 14 measurements. But CCI really should refer to the movement of the skull with respect to the spine. In the age of managed care and 15-minute appointments, the art and practice of physical examination by a physician is almost gone. Arm pain at night can be miserable. Act now before the symptoms and dysfunction progress. Punjabi and White define instability as the loss of the ability of the spine under physiological loads to maintain relationships between vertebrae in such a way that there is no damage or subsequent irritation of the spinal cord, (brain stem) or nerve roots, and in addition that there is development of deformity or incapacitating pain due to structural changes.[4]This means that the ligaments and muscles that normally hold the spine together, are too weak or damaged to handle the normal range of motion and weight of anatomic structures. 2014;14(4):432-436. doi:10.7861/clinmedicine.14-4-432, 3.Ischebeck BK, de Vries J, Van der Geest JN, et al. 24/7 simple tasks are nearly impossible due to a lack of strength and energy. Clin Med (Lond). February 28, 2023. AND neurological deficits referable to the craniocervical junction Testimonials are fundamentally unreliable. Severe complications can include meningitis and accidental injury of the vertebral artery by misplaced screws.[57]. There's no evidence that CCI surgery helps people with ME/CFS. Cervical spinal fusion is performed on patients with more severe symptoms. 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?

Craniocervical Instability and related pathologies of the craniocervical junction are an important topic for anyone diagnosed with Chiari 1 malformation. However, in more severe cases, a further surgery called an odontoidectomy may be needed to remove the odontoid process. Both procedures demand the hands of a very skilled and experienced surgeon because vital structures lie in and around the area. Your doctor is puzzled as all your tests are normal. These abnormalities can result in neck pain; syringomyelia; cerebellar, lower cranial nerve, and spinal cord deficits; and . The objective is to examine patient-reported outcomes in patients with Ehlers-Danlos Syndrome and Hypermobility Spectrum Disorder with craniocervical instability.
