目的 探讨腰椎间盘退变患者终板的形态特点，研究终板形态与椎间盘退变的相关性。方法 回顾性分析103例椎间 盘退变患者各节段椎间盘对应的终板形态，将存在退变的椎间盘和无退变的椎间盘分为两组进行对比分析。结果 正常组椎间盘中凹陷型终板多见，不规则型少见，从凹陷型、平坦型到不规则型呈递减改变。退变组椎间盘中平坦 型终板最多，不规则型最少，但其中不规则型终板的数量较正常组明显增多。终板形态从凹陷型到平坦型再到不规 则型变化过程中退变椎间盘所占的比重逐渐增加。结论 椎间盘退变常常伴随终板形态的平坦化或不规则形改变， 终板形态与椎间盘退变存在一定的相关性。

Objective To investigate the morphological characteristics of endplate in patients with lumbar intervertebral disc degeneration, and to study the correlation between the morphology of the end plate and the degeneration of the intervertebral disc. Methods A retrospective analysis of 103 cases of intervertebral disc degeneration, the corresponding end plate morphology of each segment, the degenerative intervertebral disc and non degeneration intervertebral disc were divided into two groups for comparative analysis. Results In the normal group, the depression type endplate is common in the intervertebral disc, and the irregular type is rare, and the subtraction changes from the depression type, the flat type to the irregular type. Intervertebral disc degeneration group flat type was the most irregular type at least, but the number of irregular endplates increased significantly compared with the normal group. The proportion of the degenerative intervertebral disc increased gradually during the process of the end plate form from the depression to the flat to the irregular. Conclusion The degeneration of intervertebral disc is often accompanied by flattening or irregular shape of the end plate. There is a certain correlation between the form of the end plate and the degeneration of the intervertebral disc.
