Evaluating Cervical Ligaments with Flexion, Extension and Alar X-Ray

In this video Dr. J Hartley walks you through the cervical flexion, extension and alar x-ray series, anatomy and analysis. When the cervical vertebrae are held in place as expected by normal ligament function the bones of the neck are held together tightly. When excessive motion is seen it is a sign of ligament damage or ligamentous instability. In cervical flexion if the bones of the neck slide forward it is an indication of posterior longitudinal ligament damage. In cervical extension if bones of the neck slide backward it is a sign of anterior longitudinal ligament damage. A slippage of 3.0mm or more indicates ligament damage. With the alar view or cervical lateral bending open mouth view stability of the alar and accessory ligaments are evaluate. If the lateral mass of the Atlas or first cervical slide off the second cervical or Axis it is a sign of alar and/or accessory ligamentous damage or instability. A slippage of 1.7mm or more indicates ligament damage. Ligaments in the upper neck maybe damaged in the birth process, fall on the head as a kid, sports head trauma or auto accidents. Ligament instability in the upper cervical spine ( Occiput, C1-Atlas, C2-Axis) is one of the theoretical cause of Scoliosis. The upper cervical spine houses the postural control center, thus imbalance in this area may lead to Scoliosis.
