Spatial and temporal deformation pattern of the brain from blunt trauma
… patterns of deformation within the brain during blunt trauma when changing impact parameters. A linear impactor is used to deliver controlled blows to the head surrogate, mimicking real-world blunt injury scenarios. Visual markers within head surrogates are used to motion track deformations and …

A Biomechanical Assessment Of Canine Body Armor
… response of the canine related to a behind armor blunt impact, 3) the identification of an injury criterion that will best predict canine thoracic injury as a result of behind armor blunt trauma, 4) correlation of the behind armor blunt trauma response to the standard backface testing medium …

Investigation of the Body Segment Inertial Properties and Long Bone Geometries of a Mid-Sized Male Finite Element Model
Simulations of complex blunt trauma events have become possible due to advances in computational human body modeling via finite element analysis.[3-8] These models have the potential to elucidate previously unknown injury mechanisms and can inform regulatory agencies directed at public health and …

Outcomes after thoracic endovascular aortic repair (TEVAR) in patients with traumatic thoracic aortic injuries (TTAI) - a single center retrospective review
Background: Blunt and penetrating traumatic thoracic aortic injuries constitute surgical emergencies that are attended with high mortality rates. Most patients do not survive long enough, post injury, to reach a hospital. On-site mortality rates may approach approximately 85%. Two main treatment …

Quantitative fit analysis of acromion fracture plating systems using three-dimensional anatomical modelling
… options. Methods Patients presenting to an urban trauma centre with acromial fractures sustained from blunt trauma between 2012 and 2016 were identified (n = 15, 14M / 1F). The fracture patterns were categorized according to location (Type I = 13%, Type II = 27%, Type III = 60%). Computed …

The Development and Validation of a Biofidelic Synthetic Eye for the Facial and Ocular CountermeasUre Safety (FOCUS) Headform
… left blind in at least one eye as a result of trauma. Some of the most severe eye injuries can occur in automobile accidents and from sports related impacts. Eye injuries in the military environment are even more prevalent and are generally more severe than eye injuries to civilians. The rate …

Injury Biomechanics of the Human Eye During Blunt and Blast Loading
… this thesis investigates eye injuries caused by blunt impacts and blast overpressure. This research represents part of an ongoing investigation to accurately quantify and predict eye injuries and injury mechanisms for various loading schemes. It has been shown that blunt trauma can cause severe …

Photoactivated Fixation of Cartilage Tissue
… orthopaedic conditions including fissures from blunt trauma, autograft or allograft transplantation, and replacement of focal defects with biological or synthetic constructs. In cartilage repair, initial integration between the host tissue and repair site is desirable to allow for nutrient …

Improved Cranial Fracture Metrics For Assessing The Protective Benefits Of Helmet Systems
… to cause injury, termed as Behind Helmet Blunt Trauma (BHBT). A method of assessing BHBT is required to fully understand the protective capability of a helmet system. Existing methods using synthetic head models are limited in their ability to predict injury outcome as a result of a lack …

The Molecular and Cellular Response to Pulmonary Contusion
Multi-system trauma is a significant source of patient morbidity and mortality, accounting for 140,000 deaths annually. Thoracic injuries occur in the majority of blunt trauma patients and are present in up to 75% of all trauma-related deaths. Pulmonary contusion is a common and potentially lethal …

Effective dose estimation for U.S. Army soldiers undergoing multiple computed tomography scans
Diagnosing the severity of blunt trauma injuries is difficult and involves the use of diagnostic radiological scanning. The primary diagnostic radiology modality used for assessing these injuries is computed tomography (CT). CT delivers more radiation dose than other diagnostic scanning modalities. …

The Biomechanical Response of the Eye, Face, and Orbit to Primary Blast Overpressure
… the relatively low loading rates associated with blunt trauma, little is known regarding the response of the body to the higher loading rates associated with blast trauma. While soldiers are surviving once-lethal blast events due to enhanced protective equipment, injuries such as those to the eye …

Mild traumatic brain injury augments innate immune responses through neurokinin and cholinergic signaling
… leading cause of death in the United States. Traumatic brain injury (TBI) patients have classically been considered immunosuppressed, but recent research reported that mild head trauma patients have reduced incidence of pneumonia compared to blunt trauma patients. Using our mild TBI model …

Relationship between prehospital time and 24-hour mortality following injury in patients with major trauma in New Zealand
… following injury in patients with major trauma in New Zealand (NZ). Methods: Following a systematic review to describe the incidence and characteristics of major trauma in NZ, analysis of routinely collected data from a retrospectively designed prospective cohort study was undertaken. …

Investigation of blunt injuries and the force associated with a skull fracture due to impact with a Hopkinson pressure bar : an animal model
… as a result of a firearm, sharp instrument or blunt object, may all potentially inflict severe cranial trauma. Often the lateral aspect of the cranium is fractured in homicidal assaults, however, the focus of head injury biomechanics has been the frontal bone. This is due to automotive-related …

Factors which affect the application and implementation of a spinal motion restriction protocol by prehospital providers in low resource settings: a scoping review
… and Canadian C-spine Rule (CCSR) when managing traumatic spinal injury. However, the safety and effectiveness of prehospital clinical spinal clearance or spinal motion restriction (SMR) decision support tools within poorly resourced settings are unclear. We conducted a scoping review on clinical …

Características de cães e gatos vítimas de trauma admitidos em hospital escola veterinário da região nordeste do Brasil
Trauma represents one of the main causes of morbidity and mortality in dogs and cats and constitutes the emergency challenge in veterinary medical practice. The aim of this study was to evaluate probable risk factors for not survive post-trauma in dogs and cats, as well as to analyze the usefulness …

Value of follow-up CT in head injury assessment
… follow-up CT scanning of the brain after blunt trauma to the head. RESULTS: There were 313 follow-up studies performed in 212 patients, of which the majority, 135 /313 (43.1%) were referred for neurological reasons, whilst 103/313 (32.9%) were referred for conservative management reasons …
