This patient was rear ended at approximately 8 mph with minimal automotive damages. He suffers from headaches, blurred vision, dizziness, neck and shoulder pain, and tingling down both arms and hands. This patient's spinal trauma resulted in loss of cervical curve demonstrated by Ruth Jackson's Angle at 2.32 degrees, interruption of George's Line throughout the cervical spine, and cervical spondylolisthesis Grade 1 at C3 and C4. This software technology also demonstrated that this patient's digital analysis revealed "Loss of Motion Integrity" at C4=5.13 mm posterior, yielding an impairment based on X-ray forensics at 25% whole person (AMA Guides, Fifth Edition).

Ruth Jackson's Angle is also known as Cervical Stress Lines, which measure by constructing lines of mensuration from the posterior bodies of C-2 and C-7. An angle will formed by these lines, which ordinarily intersect at C4-C5 disc interspace in the neutral and extension view and C5-C6 disc interspace in flexion. The intersection point represents the focus of stress when cervical spine is placed in respective position. Muscle spasms, joint fixation and degeneration may alter the stress point. Spondylolisthesis is an anterior displacement of 1mm or greater of one vertebral body in relation to the segment immediately below. 1-25% slippage is a grade one, 26-50% slippage is a grade two, and 51-75% is a grade three. Greater than 75% slippage is a grade four. Usually, anterior head carriage in the cervical and/or degenerative disc disease is seen at the level of the spondylolisthesis. These measurements can also be considered anterior offset and, if the offset exceeds 1mm, this indicates a functional pathology in the form described above.
