Objective: Biomechanical tests were done on the occipitalization model to clarify the three dimension movement changes of occipital-cervical region caused by the occipitalization of the atlas. 目的:建立人类寰椎枕骨化模型,进行生物力学测试,阐明寰椎枕骨化畸形对枕颈部生物力学的影响。
The Motion Changes of Atlantoaxial Joint Influenced by the Occipitalization of the Atlas: An Experiment Study 寰椎枕骨化畸形对寰枢关节运动影响的实验研究
Motion changes of occipital-cervical region influenced by the occipitalization of the atlas: an experimental study 寰椎枕骨化对枕颈部生物力学影响的实验研究
Conclusion: The biomechanical characteristics of the model in this study is conformed with that of clinical occipitalization. 结论:制作的实验模型与临床寰椎枕化畸形的生物力学特性相符。
Conclusion The biomechanical changes produced by the forward tilting and asymmetric articulations in the load-bearing joints of atlantoaxial complex which are common in patients with occipitalization of the atlas may be a more direct cause of atlantoaxial dislocation in these patients. 结论寰枕融合时寰枢椎之间承重关节常呈现不同程度的前倾和不对称,这种几何形态变化导致的关节生物力学变化有可能是寰枢椎脱位的直接原因。
Objective: To construct the biomechanical model of occipitalization of the atlas. 目的:建立人类寰椎枕化畸形的生物力学模型。
Objective To study the geometric characteristics of inferior articular facets of the atlas in patients with occipitalization of atlas. 目的研究寰枕融合患者寰椎下关节面几何形态学特征。
