The rules of atlanto-axial joint movement which are observed in the present study lay theoretical basis for diagnosing and treating atlanto-axial subluxation. 观察到的功能位寰枢关节变化规律,为诊断及治疗寰枢关节不全脱位提供了理论依据。
Atlanto-odontoid joint and lateral atlanto-axial joint osteoarthritis Atlanto-Axial Osteoarthritis: Imaging Findings and Clinical Significance 寰枢关节退变性骨关节病的影像学表现及与临床的相关性
The artificial joint can not only rebuild the stability of atlanto-axial joint, but also res-erve the rotation function between atlas and axis. 人工寰齿关节的研制是既能重建寰枢关节稳定性,又能最大限度地保留寰枢关节旋转功能的可行性技术;
Conclusion: The replacement with the artificial atlanto-odontoid joint can basically restore the stability and reserve the movement of atlanto-axial shortly after operation. 结论:在术后即刻,人工寰齿关节置换术基本能达到既稳定寰枢关节又保留其运动功能的双重目的。
Objective: To observe anatomic structure of normal atlanto-axial joint in the functional position by using CT three-dimensional imaging ( 3D) method, and to establish anatomic foundation for the diagnosis of atlanto-axial subluxation. 目的:利用CT三维成像观察正常寰枢关节功能位的解剖结构,为诊断寰枢关节不全脱位探讨解剖学基础。
Objective: To discuss the relationship between atlanto-odontoid ( AO) joint and lateral atlanto-axial ( AA) joint degeneration. 目的:探讨寰齿(AO)关节与寰枢(AA)外侧关节退变的关系。
Simple AOF would not lead to increased range of movement of flexion under physiological load, but lead to change of stress-strain environment of atlanto-axial joint and increase of ligament force that limited flexion of atlanto-axial joint. 单纯寰枕融合在生理载荷下并不能直接导致寰枢椎前屈运动范围的增加,但却可以造成寰枢关节的应力应变环境发生改变,同时限制前屈运动的韧带受力增加。
