摘要
背景:全椎间盘置换已应用多年,但国内鲜见对人腰椎间盘结构测量的大样本系统研究。目的:为中国人腰椎间盘假体置换手术和设计提供参考数据。方法:选取中国成年尸体41具(男22例,女19例),解剖获得完整的腰椎标本。测量椎体软骨板断面厚度。随机抽取正常成年人标准腰椎正侧位X射线片157例(男89例,女68例)。测量椎体上/下横径、上/下矢状径和椎间隙高度。结果与结论:成年尸体及正常成年人标准腰椎正侧位X射线片显示腰椎间盘软骨板厚度、椎体上/下横径、矢状径和椎间隙高度均不存在性别差异(P>0.05)。除L1/2相邻椎体矢状径、L3/4相邻椎体横径和L4/5相邻椎体矢状径外,其余椎间盘相邻椎体横径或矢状径的差异有显著性意义(P<0.05),但各径线实测数值之间差距均较小。腰椎间隙自L1/2至L4/5逐渐增宽,前缘高度大于后缘高度。L5/S1椎间隙与其他腰椎间隙存在较大差异,其相邻终板间夹角明显增大。
BACKGROUND：The application of total disc replacement（TDR） is common for decade years.However,there are few systematic studies with large samples addressing lumbar disc measurement related to TDR in Chinese.OBJECTIVE：To provide a reference and theoretical principle for prosthesis design and replacement procedure of the lumbar disc in Chinese.METHODS：Forty-one intact lumbar spines were anatomized in adult cadavers（male 22,female 19）,and cartilage cross-section thickness of the vertebral body was measured.Totally 157 standard lumbar spine X-ray films of normal adult（anterior-posterior and lateral views,male 89,female 68） were randomly selected.Lower/upper transverse diameter,lower/upper anteroposterior diameter and lumbar intervertebral space height were measured.RESULTS AND CONCLUSION：X-ray films of adult cadavers and normal adult with standard lumbar spine showed that there were no gender differences in cartilage cross-section thickness of the vertebral body,lower/upper transverse diameter,lower/upper anteroposterior diameter and lumbar intervertebral space height（P 0.05）.There was significant difference in adjacent vertebral body transverse diameters or adjacent antero-posterior diameters except L1/2,L4/5 antero-posterior diameter and L3/4 transverse diameter（P 0.05）.However,the differences were all slight in measurement outcomes.Lumbar intervertebral space widened gradually,and anterior height was larger than posterior height.The angle between endplates adjacent to L5/S1 intervertebral space was larger in evidence.
