摘要
目的 :为研制颈椎异体骨螺纹融合支架提供中下颈椎体解剖学数据。方法 :对 5 5具成年颈椎干燥骨标本和 35例正常颈段CT扫描片进行测量 ,确定椎体相关数据的正常范围。结果 :CT测量值大于干燥骨标本测量值 ;椎体矢状径测量值为 16 .86～ 19.5 3mm ;椎体前缘高度与椎体中间高度不等 ,最高相差可达 2～ 3mm。结论 :临床上应以CT测量值为准 ,ATFC最佳的长度为 12～ 14mm ,ATFC在椎间隙部分的高度应为 2～ 3mm。
Objective: To provide anatomical data of mid lower cervical vertebrae for the design of Allagraft Threaded Fusion Cage(ATFC).Methods:55 cervical vertebral specimens and 35 CT scan film were observed and measured to calculate the normal values of mid lower cervical vertebrae.Results:The mean value of CT scan films was greater than that of specimens.The anterior posterior diameter of mid lower cervica lvertebrae was 16.86～19.53 mm.The height of cervical vertebrae in the border was 2～3mm greater than that in certral area.Conclusion The favorite length of ATFC is about 12～14 mm,and the favorite height of ATFC is about 2～3mm.
