摘　　要：目的提出椎间盘的测量方法并测量正常成人颈椎间盘相关参数,为设计人工颈椎间盘提供参数依据。方法从深圳市第二人民医院和深圳市南山医院提取正常成人颈椎MRI数据219例,测量C4/5、C5/6、C6/73个颈椎间盘的椎间盘前高,中高,后高,椎间角,矢径及横径6组数据并作统计学分析计算。结果颈椎间盘前高为(4.27±0.73)mm,中高为(5.63±0.83)mm,后高为(3.24±0.59)mm,颈椎间盘角度为(4.73±1.57)°,颈椎间盘矢径为(15.50±1.70)mm,横径为(22.20±2.56)mm。结论上述6组数据存在性别间的显著差异性和节段间的显著差异性,设计人工颈椎间盘应设计一系列不同参数的假体以满足不同性别不同颈椎节段的需求。Objective To present a method for measuring cervical intervertebral discs of Chinese people, and provide basis for designing artificial disc. Methods MRI data of Cervical vertebra of 219 healthy Chinese adults free from cervical disease were selected. The anterior height, the middle height, the posterior height, the intervertebral angle, the sagittal diameter and the transverse diameter of cervical intervertebral discs were measured and analyzed, respectively. Results The anterior, middle and posterior heights of discs varied from 2.5mm to 6.9mm, 3.4mm to 9.3mm, and 1.9mm to 6.5mm, respectively. The intervertebral angle varied from 1.2° to 10° , the sagittal diameter varied from 11.1mm to 21.4m, while the transverse diameter varied from 16.1mm to 29.6mm. Conclusions Significance can be detected for references of cervical discs, between both gender and different segments, which is helpful for guiding the design of artificial cervical disc.
