| 摘 要： | 目的：研究人体寰椎横韧带的拉伸性能。方法：新鲜寰椎标本８例，制备成拉伸试件，进行定速率单向拉伸至横韧带断裂。结果：寰椎横韧带平均最大载荷为３１１．６Ｎ，最大变形量为６．０ｍｍ，刚度为７２．９Ｎ／ｍｍ。结论：寰椎侧块间的分离超过６．０ｍｍ，就可存在横韧带断裂。 |
| 关 键 词： | 寰椎横韧带 拉伸强度 断裂 |

| Abstract: | Objective:To analysis the tensile strength of the transverse ligament of atlas.Methods:Eight fresh adult transverse ligament specimens were subjected to fracture by a tensile force at a constant tensile speed. Results:The maximum tensile force,deformation and stiffness of the transverse ligaments were 311.9N,6.0 mm and 72.9N/mm respectively.Conclusions:The transverse ligament might fracture when two lateral masses of the atlas separated over 6.0 mm. |
| Keywords: | Transverse ligament Fracture Tensile strength |
