Mechanical Properties of Human Craniovertebral Ligaments

چکیده
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, at relevant deformation rates. Currently, there is very limited experimental data for the craniovertebral ligaments connecting the skull to the spine although much of the motion in the neck occurs at this joint, where the structure is very complex, making ligament isolation and testing difficult. The published data are limited to failure force and elongation values at quasi-static rates [2]. The purpose of this study was to investigate the tensile mechanical properties of the craniovertebral ligaments at different deformation rates, to support the development and validation of a detailed cervical spine finite element model.

A Nano-indentation Identification Technique for Viscoelastic Constitutive Characteristics of Periodontal Ligaments
Introduction: Nano-indentation has recently been employed as a powerful tool for determining the mechanical properties of biological tissues on nano and micro scales. A majority of soft biological tissues such as ligaments and tendons exhibit viscoelastic or time-dependent behaviors. The constitutive characterization of soft tissues is among very important subjects in clinical medicine and espe...

Periodontal ligament is a thin layer of soft tissue that connects root of a tooth to the surrounding alveolar bone. These ligaments play an important role in initiating tooth movement when loads are applied to teeth with orthodontic appliances. The majority of such soft tissues exhibit as viscoelastic bodies or have a time-dependent behavior. Due to the viscoelastic behavior of the periodontal ...
