Re-analysis of monkey head impact experiments to clarify traumatic brain injury kinematics and thresholds
نویسندگان
چکیده
A series of 43 traumatic head impact experiments on non-human primates carried out in the past were simulated with a validated finite element model of the specimens. From these simulations, brain tissue response and head accelerations were extracted. Based on these accelerations, existing global head injury criteria (HIC, BRIC, GAMBIT and RIC) were calculated. Correlation between the local brain tissue mechanical parameters, the global head injury criteria and the injuries scored in the experiments were analyzed. Based on this analysis, global head injury criteria that best correlate with concussion score for saggital impacts were identified and injury risk functions for brain tissue that can be used for human FE models are proposed.

ABSTRACT Background: High resolution CT scan has made early diagnosis of intraventricular hemorrhage (IVH) easier. Posttraumatic intraventricular hemorrhage has been reported to a greater extent because of the CT scan. Methods: 904 patients were admitted in the NSICU from March 2001 to March 2002 with severe closed head injury, of those only 31 patients with intraventricular hemorrhage (GCS le...

Purpose: Blast-induced traumatic brain injury (bTBI) is one of the causes of death or permanent invalidity which can occur unexpectedly in both military and civilian populations. This study set out to conduct a combined Eulerian-Lagrangian computational analysis of the interaction between a single planar blast wave and a human head in order to assess the extent of intracranial shock w...
متن کاملNon-visible penetrating brain trauma: a case report
Objective: One of the most frequent causes of death and acquired disability in the pediatric population is the Traumatic Brain Injury (TBI). TBI is secondary to falls, road traffic and vehicle collisions, child abuse and assaults. Penetrating brain injury is a severe form of traumatic brain injury. Blunt head injury is more frequent than TBI in children, but the second one carries a poor progno...
