Ulrich Batzdorf. Little research on outcomes exists. 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. Possible explanations include. This can be extremely frustrating. Adv Otorhinolaryngol. "[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]. (Learn more: www.heart.org). Craniocervical instability (CCI) occurs when the craniocervical junction at the base of the brainstem becomes 'shaky'. However, many cases of CCI are associated with some sort of connective tissue disorder, such as a heritable disorder of connective tissue (HDCT, like Ehlers-Danlos Syndrome or Marfans), or an autoimmune condition that affects the connective tissue (such as Rheumatoid Arthritis), or a few other rarer conditions that affect the integrity of bony structures in the skull and spine. [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. The constellation of symptoms caused by craniocervical instability has been labelled the cervico-medullary syndrome. Do you suffer from chronic headaches? I am a co-founder of the Centeno-Schultz Clinic which was established in 2005. Batzdorf U, Henderson F, Rigamonti D 2015. This surgery may be done through the mouth or the nose[18]. They can cause headaches, pain and cervical instability. Unfortunately, traditional MRI and CT studies do not evaluate the upper cervical spine or alar and transverse ligaments. If you have been diagnosed with Craniocervical Instability, your doctors have concluded that you have a structural disorder at the back of your head where the base of your skull (the occipital bone) and C0 (the atlas) - C1 vertebrae (the axis) function together. Many neurosurgeons do not evaluate their patients for these conditions prior to performing Chiari decompression surgery, often resulting in the need for revision surgeries and poor results. Cervical spinal instability can be difficult to detect in the shock room setting even with the utilization of computed tomography (CT) scans. BMC Musculoskelet, Vertigo caused by disorders of the cervical vertebral column. Ehlers-Danlos syndrome (EDS) is a rare hereditary condition that can result in ligamentous laxity and hypermobility of the cervical spine. What is the Alar Ligament? Visual disturbances can happen because the upper neck supplies information to the brain to guide eye position and vice versa (2). Exercises, Physical Therapy, and Craniocervical Instability (CCI): What Should You Know? However, technically, Basilar Invagination is caused by this deformation with normal bone, while Basilar Impression results from softening of bone[11]. 2018;4(1):109115. Clin Med (Lond). This can involve the alar, accessory, and transverse ligaments. 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). "[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]. Pt I The Spinal Series, Jennifer Breas Amazing ME/CFS Recovering Story: the Spinal Series Pt. This page has been accessed 251,528 times. 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. Overcoming Pain & Discomfort - Understanding the Impact of Craniocervical Instability Sport & Fitness Center Improve Your Physical Fitness .

Fortunately, this condition is treatable, though not curable. At the Centeno -Schultz Clinic all new patient evaluations undergo an extensive physical examination. Published 2016 Oct 21. doi:10.1186/s12891-016-1284-4. The objective is to examine patient-reported outcomes in patients with Ehlers-Danlos Syndrome and Hypermobility Spectrum Disorder with craniocervical instability. Craniocervical Instability & Ehlers Danlos Syndrome: Know the Facts. Symptoms of craniocervical instability include occipital headache, neck pain and neurological abnormalities such as numbness, motor weakness, dizziness, and gait instability. 20 July 2011, Greater Metropolitan Washington Area, Greater Metropolitan Washington Area,
. What are the treatment options for arm pain at night? "Consensus statement on Cervico-Medullary Syndrome." In the patient community, the term "CCI" is often used in reference to both Craniocervical Instability and Atlantoaxial Instability (AAI). This is chronic fatigue, and it is one of the common symptoms associated with craniocervical instability. supine lying on the back or with the face upward. Pain is typically localized at the base of the skull and aggravated with flexion and rotation. [citation needed] An uncovering of the facets that exceeds 20% is considered pathological. [5] No particular symptom is mandatory for a diagnosis of CCI and each symptom listed might have a cause other than CCI. Timecode: 10:34", "Basilar Invagination, Basilar Impression and Atlantoaxial Subluxation", "A Review of Complications Associated With Craniocervical Fusion Surgery", "A systematic review of occipital cervical fusion: techniques and outcomes", "Minimum 5-year Follow-up Results for Occipitocervical Fusion Using the Screw-Rod System in Craniocervical Instability", "Occipitocervical fusion with rigid internal fixation: long-term follow-up data in 69 patients", https://centenoschultz.com/cervical-joint-degeneration/, https://regenexx.com/blog/candidacy-for-ccj-instability-procedure/, https://www.nwrestorativemedicine.com/pain-solutions/neck-pain/, https://centenoschultz.com/craniocervical-instability-cci/, "Syndrome of occipitoatlantoaxial hypermobility, cranial settling, and chiari malformation type I in patients with hereditary disorders of connective tissue". Likewise, the atlantoaxial joint [the articulation between C1 (atlas) and C2 (axis)] accounts for about half of the cervical spines ability to rotate the head. 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 ). Digital Motion X-ray is considered the most accurate method. distance walked in 6 minutes. This increased mobility of the craniocervical junction may cause neurological symptoms in these patients, either due to neuronal . It is characterized by slow thinking, difficulty focusing, confusion, lack of concentration, forgetfulness, or haziness in thought.

In order to effectively address chronic headaches, you have to first determine if the pain is caused by a problem in your neck. Patient-reported outcomes like questionnaires are not objectives. The disc between the spinal bones is often times removed and replaced with a bone graft or a spacer. A subset of patients can develop clinical instability of the craniocervical junction associated with pain and neurological dysfunction, potentially warranting treatment with occipitocervical fixation (OCF). Ehlers Danlos Syndrome (EDS) is a group of inherited disorders that affect your ligaments and connective tissues (2). Complex Posterior Fossa revisions. Instability can result either from lax ligaments and other connective tissues, soft bones (also seen in HDCTs) or from something like pannus formation, where repeated rubbing together of the joints causes a build-up of granulated tissue around bony structures and changes the way certain bones lie in relationship to one another[5]. Using condylar screws may increase the risk of injury to major vessels, particularly in the hands of a less experienced surgeon. A Grabb-Oakes measurement greater than 9 mm denotes a form of basilar invagination. The procedure is called Percutaneous Implantation of Cervical Ligaments (PICL) To learn more about this groundbreaking procedure please click on the video below.
