Traumatic Distortions of the Primate Head and Chest: Correlation of Biomechanical, Radiological and Pathological Data

Abstract

<div class="htmlview paragraph">High speed cinefluorographic studies were performed on anesthetized primates during graded, experimental blunt impacts of the head or chest. Cineframe data were analyzed frame by frame to identify dynamic anatomic movement patterns during each injury. The results indicate that the brain and heart undergo significant displacements within the first few milliseconds (ms) post-impact and these transient interior motions were correlated with physiologic and pathologic changes as well as impact force and deceleration.</div>
