Experimental determination of cervical spine mechanical properties.
نویسندگان
چکیده
The results of research into human cervical spine mechanical parameters necessary for process modelling are presented. Our tests were divided into identification of tissues mechanical features and determination of data useful for validating human cervical spine models. Mechanical properties of the whole cervical spine as well as the stiffness of ligaments and discs were identified on the basis of tests on cadaveric spinal specimens. Thanks to our cooperation with medical practitioners, physiological cross-section areas of neck muscles were analysed using MRI. Functional computed tomography was used to determine kinematics of cervical vertebrae during head movement in sagittal and frontal planes.

Loading rate effect on mechanical properties of cervical spine ligaments.
Mechanical properties of cervical spine ligaments are of great importance for an accurate finite element model when analyzing the injury mechanism. However, there is still little experimental data in literature regarding fresh human cervical spine ligaments under physiological conditions. The focus of the present study is placed on three cervical spine ligaments that stabilize the spine and pro...
متن کاملMechanical Properties of Human Craniovertebral Ligaments
During physiological motion, cervical spine ligaments limit the range of motion of the neck. However, the integrity of these ligaments can be compromised under excessive loading, specifically during vehicle crash scenarios, which is the leading cause of upper cervical spine injury [1]. Techniques to predict injury, such as the use of finite element models, require accurate mechanical properties...

Background & Aim: Osteoarthritis is the most common joint disease among all the joints. It is one of the major agents of physical disabilities. Degenerative changes of the joints begin from second decade of life. Ninety percent of people have degenerative changes at 40 years of age in weight bearing joints. Osteoarthritis is common in spinal joints especially cervical spine, because of its ...

متن کاملNonlinear finite-element analysis of the lower cervical spine (C4-C6) under axial loading.
This study was conducted to develop a detailed, nonlinear three-dimensional geometrically and mechanically accurate finite-element model of the human lower cervical spine using a high-definition digitizer. This direct digitizing process also offers an additional method in the development of the finite-element model for the human cervical spine. The biomechanical response of the finite-element m...
