摘要

最近的报告强调了非典型悬吊骨折的显著发病率，但对其生物力学方面的研究仍然不足。本研究使用经过验证的有限元模型，评估了上颈椎因涉及上、下关节突、关节旁和薄板的骨折而引起的旋转力矩特征的变化。结果显示，影响上关节突和关节间旁的骨折会导致明显的不稳定性，尤其是在轴向旋转和伸展时。然而，与 Levine-Edwards II 型绞锁骨折相比，非典型绞锁骨折并不一定会产生更大的不稳定性。

Understanding cervical spine instability: a finite element study on atypical hangman's fractures.

Recent reports have highlighted a notable prevalence of atypical hangman's fractures, yet their biomechanical aspects remain underexplored. Using a validated finite element model, this study assesses changes in rotation-moment characteristics of the upper cervical spine due to fractures involving the superior and inferior articular process, pars interarticularis, and lamina. The results revealed that fractures affecting the superior articular process and pars interarticularis led to significant instability, particularly in axial rotation and extension. However, atypical hangman's fractures did not necessarily produce greater instability than Levine-Edwards type II hangman's fractures.

期刊介绍： The primary aims of Computer Methods in Biomechanics and Biomedical Engineering are to provide a means of communicating the advances being made in the areas of biomechanics and biomedical engineering and to stimulate interest in the continually emerging computer based technologies which are being applied in these multidisciplinary subjects. Computer Methods in Biomechanics and Biomedical Engineering will also provide a focus for the importance of integrating the disciplines of engineering with medical technology and clinical expertise. Such integration will have a major impact on health care in the future.
