Pathophysiology and Biomechanics

The cervical region is a highly mobile segment of the spine. At rest, in a neutral position, the normal cervical spine has a gentle lordotic configuration, due to increased disc height anteriorly. In this neutral position, the balance point between flexion and extension of the spine runs through the center of the vertebral body of C2 and the odontoid process at the occipital-cervical junction, and extends down to the cervical-thoracic junction. In this neutral position, there is a balance between flexion and extension forces across the cervical spine segment, so that minimal muscle contraction is required to maintain neck position. When the neck becomes more forward-flexed and kyphotic, more tonic paraspinal muscle contraction is required to maintain the head in the upright position.

The subaxial cervical spine facet orientation enables movements in all three primary planes. The joint spaces are flattened and horizontal, with a posterior and an inferior inclination. This configuration of the cervical facet joints enables a wide range of motion in all primary directions, including flexion/extension, lateral bending and rotation. Some of these movements can be purely in one direction and others are
