14 Mar Sunset Chiropractic & Wellness Research Review: Correlative analysis of cervical curvature and atlantoaxial instability
“After analyzing over a 100,000 of cervical static and motion based x-rays research is finally catching up with what we have observed in patients for the last 15 years of practice.”
Dr. Berry and Dr. Alfonso
“Cervical curvature straightening and inverse arch are the cause of atlantoaxial instability, the smaller the cervical curvature, the more serious the atlantoaxial instability.”
Objective: To investigate the correlation between the changes of cervical curvature and atlantoaxial instability.
Methods: The correlation between the changes of cervical curvature and atlantoaxial instability was retrospectively studied in 50 outpatients with abnormal cervical curvature (abnormal cervical curvature group) from January
2018 to December 2019. There were 24 males and 26 females in abnormal cervical curvature group, aged from 18 to 42 years old with an average of(30.62±5.83) years. And 53 patients with normal cervical curvature (normal cervical curvature group) during the same period were matched, including 23 males and 30 females, aged from 21 to 44 years with an average of(31.98±6.11) years. Cervical spine X-ray films of 103 patients were taken in lateral position and open mouth position. Cervical curvature and variance of bilateral lateral atlanto-dental space(VBLADS) were measured and recorded, Pearson correlation coefficient analysis was used to study the correlation between the changes of cervical curvature and atlantoaxial instability.
Results: Atlantoaxial joint instability accounted for 39.6%(21/53) in normal cervical curvature group and 84.0%(42/50) in abnormal cervical curvature group. There was significant difference between two groups(P<0.01). VBLADS in abnormal cervical curvature group was (1.79±1.01) mm, which was significantly higher than that in normal cervical curvature group(0.55±0.75) mm(P<0.01). Pearson correlation coefficient analysis showed that the size of cervical curvature was negatively correlated with VBLADS.
Conclusion: Cervical curvature straightening and inverse arch are the cause of atlantoaxial instability, the smaller the cervical curvature, the more serious the atlantoaxial instability.
Digital Motion X-Ray (DMX) uses advanced technology to detect ligament injuries that could never be seen before because of the lack of motion. Static x-rays, MRI and CT commonly miss injuries because you don’t or can’t move for the exam. The symptoms of a cervical disc injury are usually numbness and tingling in the upper extremities. The upper 30% of the spine and posterior aspect of the spine contain no discs, just ligaments. Headaches and posterior neck pain are commonly caused by stretched ligament injuries which cannot be detected by MRI.
Digital motion x-ray is just the opposite. It can find injuries that are evident only when you move. If your pain increases with movement, common sense tells you that your injuries should be examined “in motion”. DMX can reveal these sub-failure ligament injuries allowing the doctor to specifically determine which ligaments are injured.
Digital Motion X-Ray (DMX) helps doctors make a fast and accurate diagnosis for patients with ligament damage. In addition, Digital Motion X-Ray allows doctors to:
Make the most informed and reliable diagnosis
Provide proof of injury
Increase patient compliance and understanding
Detect ligament injuries objectively
Substantiate patient care
Anyone who has been in a motor vehicle accident (even a minor one), or has had a traumatic fall or injury can benefit from the digital motion X-ray analysis.
