Atlantoaxial Instability (AAI)
Instability simply means that bones move around too much, usually due to damaged ligaments. In the spine, this can cause nerves to get banged into and joints to get damaged. In the craniocervical junction, instability can cause the upper cervical spinal nerves to get irritated, leading to headaches. In addition, the C0-C1 and C1-C2 facet joints can also get damaged. In addition, there are other nerves that exit the skull here that can get irritated, like the vagus nerve, which can cause rapid heart rate. What’s the Difference Between CCI and AAI? CCI refers to instability in any part of the craniocervical junction…

Cervical Medullary Syndrome
Cervical Medullary Syndrome is a clinical condition that occurs as a result of inflammation, deformity, or compression of the lower part of the brain. Symptoms can be extensive with fluctuating severity based upon the extent of the underlying injury. For example, mild irritation of the brainstem may cause only mild, intermittent symptoms. The upper cervical spine and brain are complex with multiple structures. These structures reside within the skull and protective confines of the cervical spine. Neither expands to accommodate inflammation, injury, and disease. Rather the delicate tissues of the brain and spinal cord are irritated or compressed. The 4 major conditions that cause cervical medullary syndrome are…

Chiari Malformation Is a medical condition where a part of the brain at the back of the skull abnormally descends through an opening in the skull. It is named after Dr. Hans Chiari who was an Austrian pathologist who in the late 1880’s studied deformities of the brain.The brain is a large structure divided into different parts that reside within the skull. Important parts of the brain called the Cerebellum and Brainstem sit at the base of the skull. The Foramen Magnum is a large hole at the base of the skull that allows the brain to join the spinal canal. The Cerebellum…

Craniocervical Instability is a medical condition characterized by injury and instability of the ligaments that hold your head onto the neck. Common symptoms of Cranial Cervical Instability include a painful, heavy head, headache, rapid heart rate, brain fog, neck pain, visual problems, dizziness, and chronic fatigue.CCI or neck ligament laxity treatment options depend upon the severity of the instability and clinical symptoms. When appropriate, conservative care should always be the first-line treatment.
Craniocervical Instability Surgery is often recommended when conservative care fails. This involves a fusion of the head to the neck which is a major surgery that is associated with significant risks and complications…

Ehlers-Danlos Syndrome (EDS)
isorders that affect and weaken the connective tissues such as tendons and ligaments. It is a hereditary disorder which means you are born with it. EDS has many different signs and symptoms which can vary significantly depending upon the type of EDS and its severity. It most commonly affects the skin, joints, and blood vessels. Joints are typically hypermobile with excessive joint range of motion because of a defect in collagen formation. In most cases Ehlers-Danlos syndrome is inherited. That is to say that you are born with it. The two main ways EDS is inherited are: autosomal dominant inheritance and autosomal recessive inheritance…

The temporomandibular joint (TMJ) is the joint connection between your jaw and your skull. If you run your fingers along either side of your jaw line toward your ears, you can actually feel where the jaw bone ends and the skull bone begins. If you open and close your mouth, the difference between the two is dramatic as the jaw bone moves, thanks to the TMJ joint, while the skull bone remains stable. The TMJ and any of its surrounding structures can become painful and inflamed, and this can become so bad that it can prevent patients from even being able to move their jaw bone to chew.
