【摘要】： 目的:对寰枕关节进行形态学观测,探讨寰枕关节后路经关节螺钉固定通道的入钉点,瞄定点,钉道角度及螺钉长度。方法:观察枕骨髁和寰椎干燥标本并测量相关解剖数据,再依据相关参数在新鲜枕颈部尸体标本上行手术模拟置钉,术后摄片并行尸检以验证螺钉位置。结果:寰枕关节后路经关节螺钉固定的标准内倾角为20.3°±2.0°,标准上倾角为49.4°±2.4°,螺钉在枕骨髁内的适宜长度为13.94±0.96mm,在寰椎内的适宜长度为12.84±0.62mm。模拟置钉后见螺钉均通过寰枕关节起到固定作用且走行于舌下神经管下方,瞄定点中有68.75%在枕骨髁前上方近似于三角形的最佳区域内。结论:寰枕关节后路经关节螺钉固定在解剖上可行,以寰椎后弓与侧块下关节突移行处中点作为入钉点,把握标准内倾角及上倾角,选择适宜长度的螺钉则能有效完成寰枕关节后路经关节螺钉固定。
[Abstract]:Objective: To observe the morphological observation of atlantooccipital joint, explore the point of entry, point of sight, angle and length of screw in the fixation channel of atlantooccipital posterior approach. Methods: To observe the dry specimens of the occipital condyle and Atlas and to measure the related anatomical data, and then to simulate the operation of the fresh occipital and cervical cadavers according to the relevant parameters. Results: the standard internal obliquity of the posterior atlantooccipital joint through the articular screw was 20.3 + 2 degrees, the standard obliquity was 49.4 + 2.4 degrees, the appropriate length of the screw in the occipital condyle was 13.94 + 0.96mm, and the suitable length of the atlas was 12.84 + 0.62mm. after the atlantooccipital joint. To the fixed effect and walk below the sublingual nerve canal, 68.75% of the occipital condyles are located in the best area of the triangle. Conclusion: the posterior approach of the atlantooccipital joint is anatomically feasible, and the posterior arch of the atlas and the lower joint of the lateral mass are taken as the point of the nail, and the standard inclination angle and the obliquity are selected. Appropriate length screws can effectively achieve atlantooccipital joint posterior articular screw fixation.
