文题释义:
腰椎人工椎间盘:既往腰椎手术中,单纯的髓核摘除虽然可以解除突出组织对神经根及脊髓压迫,缓解腰部及下肢疼痛麻木,但是形成了椎间盘内的空洞,从而导致椎间盘高度丢失,小关节容易移位,椎管狭窄。而腰椎融合手术虽然稳定了腰椎但却改变了力学,加速相邻椎间盘退变。因此,临床工作者一直寻求一种更好的方法,而腰椎人工椎间盘就是理想代替方案。
矢状位平衡:近期研究发现,腰椎术后的临床效果与腰椎矢状位平衡有紧密联系。因此,人工椎间盘置换成为解决方案之一,其通过维持矢状位平衡、保持高度、维持力学、保护神经、早期康复而阻止相邻节段退变及病变引发疼痛。
 
摘要
背景:人工椎间盘需要高度、宽度、形状尽可能和原有椎间盘相似,才能更好的分布载荷。目前大部分数据来自国外或应用X射线、MRI等仪器测量得出,但都存在一定不足。
目的:对正常腰椎椎间盘进行CT测量,以期为脊柱疾病诊断及设计适合国人的腰椎人工椎间盘装置提供数据。
方法:收集2012年1月至2017年5月于柳州市工人医院行腰椎CT检查患者共2 235例,经严格纳入排除标准后符合条件者共62例,其中男45例,女17例。从20岁起,10年为界限,分为20-30,31-40,41-50及>50岁组,共4组,节段范围L1-S1。测量指标包括椎间盘前后径距离、横径距离,椎间盘体积大小,椎间隙矢状位前中后高度,冠状位左右高度及椎间隙角度。
结果与结论:①在年龄方面,在L1/2、L2/3、L3/4这些节段上大部分指标差异有显著性意义(P < 0.05),需考虑年龄差异;而L4/5、L5/S1节段上大部分指标差异无显著性意义(P > 0.05);②各节段矢状位上前高与中高、后高高度比较,差异均有显著性意义(P < 0.05);③L2/3、L3/4、L4/5、L5/S1椎间隙角度之间差异均有显著性意义(P < 0.05),但是L4/5与L5/S1之间角度变化最大;④冠状位上左右两侧高度比较,两者间差异无显著性意义(P > 0.05);⑤相邻横断面上前后径及横径比较,两者间差异有显著性意义(P < 0.05);⑥结果显示,节段越往下,各节段测量指标统计学差异越小。表明腰椎人工椎间盘或椎间融合器设计上,在L1/2、L2/3、L3/4这些节段上需考虑年龄差异;腰椎人工椎间盘可从中间或侧方放置;人工椎间盘需设计成锲形而不是矩形。这些将为设计国产腰椎人工椎间盘提供良好的解剖学依据。

Abstract:

BACKGROUND: The artificial disc requires a height, a width, and a shape as much as possible to be similar to the original intervertebral disc in order to perfectly distribute the load. At present, most of the data are from foreign countries or measured using X-ray and magnetic resonance imaging, but there are some shortcomings.

OBJECTIVE: To diagnose the spinal disease and provide data for the design of a native lumbar disc device by measuring the normal lumbar intervertebral disc using computer tomography (CT).
METHODS: A total of 2 235 patients who underwent lumbar CT examination in Liuzhou Worker’s Hospital from January 2012 to May 2017 were collected and analyzed. There were 62 cases, including 45 males and 17 females, after being strictly met the inclusion and exclusion criteria. From the age of 20, they were divided into four groups: 20-30, 31-40, 41-50 and more than 50 years old. The range was from L1 to S1. The measurement index include intervertebral disc anteroposterior diameter, transerverse diameter, disc volume, sagittal anterior, middle and posterior height, coronal left and right height, and interverterbral angle.
RESULTS AND CONCLUSION: (1) In terms of age, there was a statistically significant difference in measurement indexes between L1/2, L2/3 and L3/4 (P < 0.05). Therefore, the factor of age should be taken into account. However, there was no statistically significant difference between L4/5 and L5/S1 segments (P > 0.05). (2) There was a statistical difference between the anterior and middle height of the sagittal position in L4/5 and L5/S1 (P < 0.05). (3) There were statistical differences between the angles of L2/3, L3/4, L4/5, L5/S1 intervertebral space (P < 0.05), but the difference of angle between L4/5 and L5/S1 was the most. (4) There was no statistical difference in the height between the left and right sides of the coronal position (P > 0.05). (5) There was statistical difference between the anteroposterior and transverse diameters of the disc on the adjacent cross section (P < 0.05). (6) The results showed that the lower the segment, the smaller the statistical difference between each group. It is indicated that the age difference should be considered on the L1/2, L2/3, and L3/4 segments in the design of lumbar disc or interbody fusion. The lumbar artificial intervertebral disc can be placed in the middle or side. The artificial disc should be designed into the wedge shape instead of a rectangle. These will provide a good anatomical basis for the design of domestic lumbar artificial intervertebral discs.
