Preamble: many of these issues I bring are small, yet each issue is just that… an issue. If you take care of the small issues, then you will be able to build and focus on the larger issues… a larger, more profitable practice along with more family time. 

“AOMSI Significance”

The following is from Ray Wiegand DC, who is arguably the “grandfather of Spinal Biomechanical Engineering analysis” worldwide. I have asked him to send snippets on a regular basis to help you further understand ligament pathology as sequella from trauma. 

Alteration of Motion Segment Integrity

AOMSI is a serious condition that has clinical consequences.  Nearly 70% of files submitted show a positive result for at least one motion segment. Of that group 40% show two or more levels of instability. 

When AOMSI is found it is indicative of injury equivalent to transecting more than 50% of the motion segment ligaments.  Yielding of the ligament is also equivalent. Yielding means the ligament has been stretched beyond its elastic limit and internal disruption to the ligament fibers has occurred. The ligament loses its ability to elastically rebound. The ligament will not provide stabilization and it is permanently injured. Two scenarios are concurrent. The ligament is broken and or it has been stretched to functional destruction. 

Injured ligaments and forward head posture lead to degeneration, compensation and destabilization.  Don’t short change your patients. All patients with a history of a sudden impact injury should be tested for AOMSI for the cervical and lumbar regions. You may be the patients’ only advocate to insure appropriate compensation today for the consequences that will occur in the future. 

Think about it.
