Causes of Atlantoaxial Instability Central nervous system nerve tension is typically from upper cervical instability and not only affects the cervical spinal cord but can involve the brainstem and brain. Clin Orthop Relat Res. When there is long-term degeneration of the posterior column of the spinal cord one can get paresthesia’s of the legs, poor balance with walking, bowel and bladder problems, decrease position and vibratory sense in the lower extremities, numb feels in legs and feet, and when the anterior spinal cord corticospinal tracts degenerate muscle atrophy in the legs and feet can occur. Type 2 and 3 atlantoaxial instability, wherein there is no compression of either the dural tube or the neural structures that are labelled as central or axial atlantoaxial instability. Congenital vertebral malformations along with abnormality or absence of ligamentous structures lead to contusion or compression of the cervical spinal cord and caudal brainstem. But what about patients whose symptoms are at best difficult to understand or difficult to determine what is causing them? They tell a story of many challenges.

Atlantoaxial Instability. Xie Y, Li Z, Tang H, Li M, Guan Z. Posterior C1 lateral mass and C2 pedicle screw internal fixation for atlantoaxial instability. Based on this close anatomical relationship between the cervical spine, the vertebral arteries, and cerebral vasculature, we hypothesized that improvement in cervical hypolordosis increases collateral cerebral artery hemodynamics and circulation. [Medline]. When we first examine people as new patients, a message that we try to have them understand is that the word instability should draw a picture for them of the word destruction. The reason people tell us that their brain scans show nothing is that the scans are showing nothing while the patient is lying prone during their test. In conjunction with degenerative disc disease, a distinct but functionally related condition, facet arthropathy is believed to be one of the most common causes of lower back pain. Atlantoaxial instability (AAI) is characterized by excessive movement at the junction between the atlas (C1) and axis (C2) as a result of either a bony or ligamentous abnormality. Craniovertebral junction abnormalities in Down syndrome. Rheumatoid arthritis (RA) causes persistent synovitis which could lead to bone erosion, loss of joint cartilage and loose of ligament. Views during flexion, as tolerated by the patient, show dynamic instability of the entire cervical spine. The disorder affects cats, but is generally found in smaller breeds and is uncommon in older cats. 66 (4):568-74. This problem is caused by a combination of low tone, loose ligaments and bony changes. Asian Spine J. If the blood flow is intermittently compromised, such as only when the neck is in certain positions, it will be difficult to catch and diagnose. The most common birth defect is an absent or smaller than usual dens (called aplasia and hypoplasia, respectively). Marfan Syndrome, neurofibromatosis, connective tissue conditions like rheumatoid arthritis, or Ehlers-Danlos Syndromes (EDS), as a result of physical trauma, or infection. Atlantoaxial subluxation is misalignment of the 1st and 2nd cervical vertebrae, which may occur only with neck flexion. Object: Understanding that atlantoaxial instability is the cause of Chiari malformation (CM), the author treated 65 patients using atlantoaxial stabilization. 69 (2):136-48.

Mosby, 2007. [Medline]. Conclusion? [Medline]. Fusions at the craniovertebral junction. Cervical instability is a progressive disorder causing a normal lordotic curve to end up as an “S” or “Snake” curve with crippling degeneration. The occipitus, atlas, and axis are the three bones that comprise the craniovertebral junction. AAI can occur as a result of abnormalities or trauma associated with c1-c2… The spinal cord can be pressed by the bones and cause nerve damage. Prone positions and non-prone positions create a different blood flow.

Whether it is flexion/extension cervical x-rays, open mouth lateral flexion x-rays, flexion/extension MRI’s, MRI’s with thin slices to examine the ligaments of the craniocervical junction or doppler ultrasound of the head and neck it is best to have the tests in house, that is the only way to guarantee that the exam was done exactly what the patient needs and interpreted correctly. Laxity of Daniel Murrey, MD Co-President, OrthoCarolina Acta orthop. The disorder is uncommon in older dogs and larger breeds of dogs. This spinal disorder is most commonly seen in young, small breed dogs, such as Toy Poodles, Miniature Poodles, Yorkshire Terriers, Pomeranians, and Chihuahuas. When the cervical ligaments are healthy, your head movement is healthy, pain-free, and non-damaging. A continuation of this discussion can be found in these articles on our website: We hope you found this article informative and it helped answer many of the questions you may have surrounding how cervical spine instability disrupts blood flow into the brain and causes many neurological problems. Ilkko E, Tikkakoski T, Pyhtinen J. AAI or AAS associated with bony abnormalities can be caused by abnormal development or ossification of the odontoid or fracture with or without remodeling. Previous. Spine (Phila Pa 1976). 1987 Oct. 80 (4):555-60. Li WL, Chi YL, Xu HZ, Wang XY, Lin Y, Huang QS, et al. [Medline]. Because of the nature of his injury and ligament damage in his cervical spine, the patient underwent eight prolotherapy treatment sessions. In our research that we will demonstrate below, we were able to get good outcomes with simple dextrose Prolotherapy injections that stimulated repair and restoration of the damaged cervical neck ligaments. Cervical spine fractures can occur secondary to exaggerated flexion or extension, or because of direct trauma or axial loading.. 71 (3):381-92. for: Medscape.

Mosby, 2007. [Medline]. Conclusion? [Medline]. Fusions at the craniovertebral junction. Cervical instability is a progressive disorder causing a normal lordotic curve to end up as an “S” or “Snake” curve with crippling degeneration. The occipitus, atlas, and axis are the three bones that comprise the craniovertebral junction. AAI can occur as a result of abnormalities or trauma associated with c1-c2… The spinal cord can be pressed by the bones and cause nerve damage. Prone positions and non-prone positions create a different blood flow.

[Medline]. [Medline]. In a 2015 paper appearing in the Journal of Prolotherapy, (3) our research team wrote that cervical ligament injury should be more widely viewed as the underlying pathophysiology (the cause of) atlantoaxial instability and the primary cause of cervical myelopathy (disease) including the problems of Vertebrobasilar insufficiency. (2) It comes in part from the National Institute of Mental Health and Neurosciences in India. Through extensive research and patient data analysis, it became clear that in order for patients to obtain long-term cures (approximately 90% relief of symptoms) the re-establishment of some lordosis, (the natural cervical spinal curve) in their cervical spine is necessary.

The neurons, as described above, are big consumers of food fuel to create energy. The reason it can not be found is that the nerve impulses are not structurally getting impeded all the time but intermittently when the body is moved in a certain way until there is too much tension on it to carry nerve impulses normally. In this group of patients, it would not take much by way of neck rotation compression to cut off blood flow to the brain in arteries that are internally clogged. 2005 May. When people suffer from unusual dysesthesias, even with a lot of MRIs, blood tests, and many visits to various specialists, no underlying etiology is found let alone a definitive curative treatment. CCI can be subdivided in to Occipito-axial Instability (OAI) also known as Atlanto-occipital Instability (AOI) and Atlanto-axial Instability (AAI), affecting 17.5% and between 6.8- 30% of people with Down Syndrome respectively.

Causes of Atlantoaxial Instability Central nervous system nerve tension is typically from upper cervical instability and not only affects the cervical spinal cord but can involve the brainstem and brain. Clin Orthop Relat Res. When there is long-term degeneration of the posterior column of the spinal cord one can get paresthesia’s of the legs, poor balance with walking, bowel and bladder problems, decrease position and vibratory sense in the lower extremities, numb feels in legs and feet, and when the anterior spinal cord corticospinal tracts degenerate muscle atrophy in the legs and feet can occur. Type 2 and 3 atlantoaxial instability, wherein there is no compression of either the dural tube or the neural structures that are labelled as central or axial atlantoaxial instability. Congenital vertebral malformations along with abnormality or absence of ligamentous structures lead to contusion or compression of the cervical spinal cord and caudal brainstem.

Where it sits in front of the transverse processes of the C1 (atlas) and C2 (axis) makes it vulnerable to compression by cervical spine instability if the C1 and C2 are unstable. Rheumatoid spondylitis, for example, primarily affects the cervical spine and can cause atlantoaxial instability or true atlas subluxation that should not be manipulated. This is one explanation for severe brain fog and mental decline in people with upper and lower cervical instability. “Vertebral arteries proceed superiorly, in the transverse foramen of each cervical vertebra and merge to form the single midline basilar artery” which continues to the circle of Willis and cerebral arteries. Spine (Phila Pa 1976). Symptoms did not develop for months. 2014 Feb. 27 (1):11-28. Associated autonomic dysfunction in cervical myelopathy patients predisposes them to hemodynamic (blood flow) changes. One of the troubling similarities amongst the wide array of symptoms is how many patients tell us that no one else has been able to find the cause.

Based on this close anatomical relationship between the cervical spine, the vertebral arteries, and cerebral vasculature, we hypothesized that improvement in cervical hypolordosis increases collateral cerebral artery hemodynamics and circulation. [Medline]. When we first examine people as new patients, a message that we try to have them understand is that the word instability should draw a picture for them of the word destruction. The reason people tell us that their brain scans show nothing is that the scans are showing nothing while the patient is lying prone during their test. In conjunction with degenerative disc disease, a distinct but functionally related condition, facet arthropathy is believed to be one of the most common causes of lower back pain. Atlantoaxial instability (AAI) is characterized by excessive movement at the junction between the atlas (C1) and axis (C2) as a result of either a bony or ligamentous abnormality. Craniovertebral junction abnormalities in Down syndrome. Rheumatoid arthritis (RA) causes persistent synovitis which could lead to bone erosion, loss of joint cartilage and loose of ligament. Views during flexion, as tolerated by the patient, show dynamic instability of the entire cervical spine. The disorder affects cats, but is generally found in smaller breeds and is uncommon in older cats. 66 (4):568-74.

Marfan Syndrome, neurofibromatosis, connective tissue conditions like rheumatoid arthritis, or Ehlers-Danlos Syndromes (EDS), as a result of physical trauma, or infection. Atlantoaxial subluxation is misalignment of the 1st and 2nd cervical vertebrae, which may occur only with neck flexion. Object: Understanding that atlantoaxial instability is the cause of Chiari malformation (CM), the author treated 65 patients using atlantoaxial stabilization. 69 (2):136-48. Causes include: Trauma (one major trauma or repetitive microtrauma or delayed or missed diagnosis of cervical spine injury after trauma (car accident rugby neck injury) . Get our FREE 4th Edition Prolotherapy e-book! The patient had these symptoms for 3 – 4 months.

Atlanto-axial rotatory fixation. This made him fearful of sleeping. adult causes. Transcranial doppler (TCD) can track real-time, moment-to-moment changes in blood flow to the brain. Caring Medical has published dozens of papers on Prolotherapy injections as a treatment in difficult to treat musculoskeletal disorders. Whether it is flexion/extension cervical x-rays, open mouth lateral flexion x-rays, flexion/extension MRI’s, MRI’s with thin slices to examine the ligaments of the craniocervical junction or doppler ultrasound of the head and neck it is best to have the tests in house, that is the only way to guarantee that the exam was done exactly what the patient needs and interpreted correctly. Laxity of Daniel Murrey, MD Co-President, OrthoCarolina Acta orthop. The disorder is uncommon in older dogs and larger breeds of dogs.

When the cervical ligaments are healthy, your head movement is healthy, pain-free, and non-damaging. A continuation of this discussion can be found in these articles on our website: We hope you found this article informative and it helped answer many of the questions you may have surrounding how cervical spine instability disrupts blood flow into the brain and causes many neurological problems. Ilkko E, Tikkakoski T, Pyhtinen J. AAI or AAS associated with bony abnormalities can be caused by abnormal development or ossification of the odontoid or fracture with or without remodeling. Previous. Spine (Phila Pa 1976). 1987 Oct. 80 (4):555-60. Li WL, Chi YL, Xu HZ, Wang XY, Lin Y, Huang QS, et al. [Medline]. Because of the nature of his injury and ligament damage in his cervical spine, the patient underwent eight prolotherapy treatment sessions. In our research that we will demonstrate below, we were able to get good outcomes with simple dextrose Prolotherapy injections that stimulated repair and restoration of the damaged cervical neck ligaments. Cervical spine fractures can occur secondary to exaggerated flexion or extension, or because of direct trauma or axial loading.. 71 (3):381-92. for: Medscape. Like reaching above their head for something, turning their head to the side, or walking among other daily routines. Spine (Phila Pa 1976). Neva MH, Häkkinen A, Mäkinen H, Hannonen P, Kauppi M, Sokka T. High prevalence of asymptomatic cervical spine subluxation in patients with rheumatoid arthritis waiting for orthopaedic surgery. Mosby, 2007. [Medline]. Conclusion? [Medline]. Fusions at the craniovertebral junction. Cervical instability is a progressive disorder causing a normal lordotic curve to end up as an “S” or “Snake” curve with crippling degeneration. The occipitus, atlas, and axis are the three bones that comprise the craniovertebral junction. AAI can occur as a result of abnormalities or trauma associated with c1-c2… The spinal cord can be pressed by the bones and cause nerve damage. Prone positions and non-prone positions create a different blood flow.
