Although the cervical spine supports and controls the kinematics of the head, it is vulnerable to injuries during mechanical loading. Severe injuries often result in damage to the spinal cord, leading to significant ramifications. The role of gender in determining the outcome of such injuries has been established as significant. In order to better understand the essential mechanics and develop treatments or preventative measures, various forms of research have been conducted. Computational modelling is one of the most useful and extensively utilised methods, as it provides information that would otherwise be difficult to obtain. As such, the primary goal of this research is to create a new finite element of the female cervical spine that will more accurately represent the group most affected by such injuries. This work is a continuation of a previous study where a model was created from the computer tomography scans of a 46-year-old female. A functioning spinal unit consisting of the C6-C7 segment was simulated as a validation procedure. The experimental data obtained from cadaveric specimens, that assessed the range of motion of different cervical segments in flexion-extension, axial rotation, and lateral bending, was used to validate the reduced model.
虽然颈椎支撑和控制着头部的运动，但它在机械负荷下容易受伤。严重的损伤通常会导致脊髓损伤，造成重大后果。性别在决定此类损伤的结果方面起着重要作用。为了更好地了解基本力学并开发治疗或预防措施，已经进行了各种形式的研究。计算建模是最有用和广泛使用的方法之一，因为它提供了否则难以获得的信息。因此，这项研究的主要目标是创建一个新的女性颈椎有限元模型，该模型将更准确地代表受此类损伤影响最大的人群。这项工作是之前一项研究的延续，该研究从一名 46 岁女性的计算机断层扫描图像中创建了一个模型。作为验证程序，模拟了由 C6-C7 节组成的功能脊柱单元。从尸体标本获得的实验数据评估了不同颈椎节段在屈伸、轴向旋转和侧屈中的运动范围，用于验证简化模型。
