Relationship between Cervical Spine Curvature and Risk of Injury in the Case of Sagittal Impact: a Finite Element Analysis
نویسندگان
چکیده
RISK OF INJURY AT THE CERVICAL LEVEL during automotive crashes is difficult to assess. Injury tolerance values were shown to be very dependent from intrinsic or extrinsic parameters and their relevance is still controversial. The curvature of the human neck presents a great variability (Matsumoto 1998) and may be influenced by a seated posture (Black 1996). The aim of this study is to assess the effects of various curvatures of the human cervical spine on the behavior of the neck submitted to frontal and rear-end impact using an omni-directionally validated three-dimensional FE neck model of a 50th percentile adult.

Predicting the Risk of Hearing Impairment Following the Cervical Spine Diseases by Measuring the Cervical Range of Movements: A Pilot Study
Introduction: Cervical spine abnormalities can affect the ear vessels and or nerves with different mechanisms. Ear dysfunctions following cervical spine injuries can be manifested as hearing loss, vertigo, or tinnitus. Usually, cervical spine injuries can cause pain and Range of Motion (ROM) limitation. The major objective of this study was to determine which cervical ROM limitation was accompa...

Cervical spinal instability due to ligamentous injury, degenerated disc and facetectomy is a subject of great controversy. There is no analytical investigation reported on the biomechanical response of cervical spine in these respects. Parametric study on the roles of ligaments, facets, and disc nucleus of human lower cervical spine (C4-C6) was conducted for the very first time using noninvasiv...

Background: Office workers spend a long period of time behind a computer during working hours. The relation between the posture of sitting during work with computer and neck pain is still debatable. Even though some researchers claim a significant difference in head posture between patients with neck pain and pain-free participants, the FHP (forward head posture) has not always been associate...
