Cervical radiographs taken one year before chiropractic attention. (A) Frontal cervical X-ray shows a tilt to the right and degenerative hypertrophy of the facets (white arrows) and uncovertebral joint (yellow arrows). Dashed red line highlights malalignment of the C-5 spinous process, indicative of a vertebral rotation. (B) Lateral cervical x-rays revealed a loss of cervical lordosis (yellow line highlights posterior vertebral body margins). Global cervical curve is 0°, using the posterior vertebral body of C2 and the posterior vertebral body of C7. The exostoses (red circles) in the spinous process interspaces indicate a chronic injury of the nuchal osteo-ligamentous attachment. The craniovertebral angle is 68°. An angle less than 50° will be defined as forward head posture.
