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。

Abstract:

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.
