A good read to understanding alteration of motion segment integrity (AOMSI) is the article �Biomechanical Analysis of clinical instability in the cervical spine� White, et al., Clin Ortho Relat Res, 1975;(109):85-96.
AOMSI is a biomechanical analysis. It�s all about numbers that have clinical meaning and significance. Threshold values have been determined that quantify without a doubt the patient has serious injury. It is a test of structural integrity of the ligaments interconnecting the motion segments. In this case, structural integrity has to do with the material properties of ligament tissue. Those properties include strength and flexibility. When a material is both strong and flexible, it�s called a semi-rigid material. Strength is related to the composition of the material. Strength might be thought of as load carrying capacity before failure.
Mechanism of Injury: Ligaments
Ligament tissue has previously been bench tested to de
