It happened in a flash. The traffic light turned red, cars halted, and then – bam! An SUV crashed into your rear. Since then, relentless headaches and dizziness have become your unwelcome companions, stubbornly resisting all treatments. Doctors are baffled because your tests come back normal. Could it be Craniocervical Instability (CCI)? What role does the Alar Ligament play? And crucially, what are the 7 major criteria for an accurate Cervical Instability Diagnosis? Let’s delve into understanding cervical instability diagnosis and shed light on these critical questions.
What is Craniocervical Instability (CCI)?
Craniocervical Instability (CCI) is a medical condition characterized by the loosening or laxity of the robust ligaments that connect your head to your upper neck (1). The primary ligaments affected are the Alar, Transverse, and Accessory ligaments. These ligaments are essential for maintaining the stability of your head and neck.

Understanding the Alar Ligament’s Role in Cervical Stability
Ligaments, acting as strong bands of connective tissue, bridge bone to bone. The Alar ligaments specifically link the upper neck to the skull. As illustrated, a pair of Alar ligaments, right and left, work in tandem to provide crucial stability to your head and neck.

7 Key Criteria for Diagnosing Cervical Instability
Accurate cervical instability diagnosis is paramount for effective treatment and optimal patient outcomes. Diagnosing craniocervical instability involves a comprehensive evaluation based on 7 main criteria:
1. Mechanism of Injury: Uncovering the Cause
Understanding how and when the injury occurred is a critical first step in cervical instability diagnosis. Trauma and underlying medical conditions that predispose individuals to ligament laxity are the two most prevalent causes of CCI (2). Common traumatic events include motor vehicle accidents, participation in contact sports, and forceful chiropractic manipulations. Furthermore, conditions like Ehlers Danlos Syndrome (EDS), a group of inherited disorders affecting connective tissues and ligaments, can also lead to CCI (2). Identifying the mechanism of injury provides valuable context for cervical instability diagnosis.
2. Symptom Evaluation: Recognizing the Signs of Cervical Instability
The range and severity of symptoms associated with CCI can vary significantly depending on the degree of instability. However, some of the most frequently reported symptoms that contribute to cervical instability diagnosis include:
Debilitating Headaches
These are not typical headaches. CCI-related headaches are often described as severe, persistent, and significantly impacting daily life. They are a key indicator in cervical instability diagnosis, distinct from common tension headaches.
Upper Neck Pain
Pain localized at the base of the skull is a hallmark symptom. This pain is often exacerbated by neck flexion and rotation. Patients may describe the pain radiating upwards towards the top of the head, the base of the skull, or even behind the eyes. The specific location and aggravating factors of neck pain are important clues in cervical instability diagnosis.
Dizziness and Balance Issues
Balance disturbances in CCI can range from mild unsteadiness to severe vertigo, sometimes making even simple tasks like walking challenging. These balance problems are a significant symptom to consider in cervical instability diagnosis.

Visual Disturbances
Visual symptoms can manifest in various forms, including blurred vision, reduced visual acuity, and alterations in peripheral vision (3). These visual disturbances are crucial to note during cervical instability diagnosis as they reflect neurological involvement.

Brain Fog
Cognitive difficulties, often described as “brain fog,” are common in CCI patients. This can include challenges with memory, concentration, and task completion. Patients may feel a persistent sensation of mental cloudiness. Brain fog is an increasingly recognized symptom in cervical instability diagnosis.

3. Physical Examination: The Importance of Hands-On Assessment
In today’s healthcare environment, where appointment times are often constrained, the thorough physical examination is sometimes overlooked. At Centeno-Schultz Clinic, every new patient undergoes a comprehensive physical evaluation. This is because a holistic view of the body is essential in cervical instability diagnosis. Physical findings in the neck, head, shoulder, and lower back can provide valuable insights into CCI. A detailed physical exam remains a cornerstone of accurate cervical instability diagnosis.
4. Radiographic Studies: Imaging for Cervical Instability
Various radiographic studies, including X-rays, CT scans, and MRIs, play a crucial role in medical diagnosis. However, standard MRI and CT scans are often inadequate for evaluating the upper cervical spine and the alar and transverse ligaments. Cervical instability diagnosis often necessitates specialized radiographic techniques, such as upper cervical MRI or rotatory CT scans. Furthermore, dynamic studies, where imaging is performed during patient movement, are particularly useful for identifying instability. Examples include upright MRI with flexion and extension views. The video below illustrates this process.

Digital Motion X-ray (DMX) is another valuable tool in establishing a cervical instability diagnosis. DMX is a recorded X-ray examination capturing neck movements in real-time, including flexion, extension, and lateral bending. To learn more about DMX, please watch the video below.

5. Response to Conservative Care: Gauging Treatment Effectiveness
The symptoms of CCI can overlap with other conditions. For instance, headaches and dizziness can also stem from tight neck muscles. Therefore, assessing the response to conservative treatments is essential in cervical instability diagnosis. These conservative measures typically include rest, heat therapy, stretching exercises, physical therapy, massage, and chiropractic care. While some patients experience symptom relief with conservative therapy, persistent symptoms despite these interventions may strengthen the suspicion of CCI and support cervical instability diagnosis.
6. Response to Diagnostic Injections: Pinpointing the Pain Source
Diagnostic injections involve precisely injecting a specific structure to determine if it is the source of pain. This technique can be highly informative in evaluating patients for cervical instability diagnosis. These injections are always performed under image guidance, such as ultrasound, X-ray, or both, to ensure accuracy. Examples of diagnostic injections used in cervical instability diagnosis include:
- C0-1 and C1/2 facet injections
- Occipital nerve blocks
- Superficial Cervical Plexus Blocks
- Ligament injections
The patient’s response to these injections provides critical information for confirming cervical instability diagnosis.
7. Level of Disability: Assessing Functional Impact
In many CCI cases, the severity of symptoms significantly impairs a patient’s ability to perform daily domestic and professional tasks. In severe cases, individuals may become homebound and socially isolated. The level of disability experienced by the patient is an important factor considered in cervical instability diagnosis, reflecting the functional consequences of the condition.
Percutaneous Implantation of Cervical Ligaments (PICL): A Non-Surgical Treatment Option
Centeno-Schultz Clinic pioneered a groundbreaking non-surgical treatment for cervical instability in 2015. This innovative procedure, known as Percutaneous Implantation of Cervical Ligaments (PICL), involves injecting a patient’s own bone marrow-derived stem cells into the damaged alar and transverse ligaments. PICL is a technically demanding procedure exclusively performed at the Centeno-Schultz Clinic in Broomfield, Colorado. To gain a deeper understanding of this advanced treatment option, please watch the video below.

Conclusion: Taking Steps Towards Cervical Instability Diagnosis and Treatment
Cranial Cervical Instability (CCI) is a condition marked by the laxity of ligaments supporting the head and upper neck. Accurate cervical instability diagnosis relies on a combination of 7 key criteria: injury mechanism, symptoms, physical examination findings, radiographic studies, response to conservative care, response to diagnostic injections, and level of disability. The PICL procedure offers a promising non-surgical approach to treating CCI by utilizing a patient’s stem cells to repair damaged upper cervical ligaments, presenting a less invasive alternative to surgery and its associated risks.
If you or someone you know has experienced an injury and is suffering from persistent headaches, dizziness, and brain fog that haven’t responded to conventional treatments, cervical instability might be the underlying issue. We encourage you to schedule either an in-office or telemedicine consultation with a board-certified, fellowship-trained physician to determine if your symptoms align with the criteria for cervical instability diagnosis. Early action is crucial to prevent symptom progression and expand your treatment options.
