腰椎间盘和腰椎小关节的退变顺序及其与年龄的相关性分析

Analysis on relationship between lumbar disc and lumbar facet joint degeneration sequence with age

目的探讨腰椎间盘和腰椎小关节退变的顺序及其与年龄的相关性。方法选取2014年1月至2016年6月在该院就诊的影像学资料齐全的腰腿痛患者600例,应用Pfirrmann方法对椎间盘退变进行判定,应用Weishaupt分级标准对腰椎小关节退变进行判定,对所有患者L_(3~4)、L_(4~5)、L_5~S_1节段椎间盘和小关节进行分级评判,并分别记录各退变级别的发生率和年龄段分布,分析椎间盘及小关节退变与年龄的相关性及二者退变的顺序。结果腰椎间盘退变和腰椎小关节退变与年龄增长呈正相关(r=0.56、0.62,P<0.05)。<45岁患者腰椎小关节退变率大于腰椎间盘退变率;≥45岁患者椎间盘退变率大于腰椎小关节退变率。结论腰椎间盘及小关节退变与年龄密切相关;早期以腰椎小关节退变为主,后期以腰椎间盘退变为主。

Objective To analyze the correlation between the lumbar disc and lumbar facet joint degeneration sequence with the age.Methods Six hundreds patients with lumbocrural pain and intact imaging data in this hospital from January 2014 to June 2016 were selected.The intervertebral disc degeneration was judged by using the Pfirrmann method and the Weishaupt classification criterion was used to judge the degeneration of lumbar facet joint.The intervertebral discs and facet joints at L 3-4,L 4-5 and L 5-S 1 were performed the graded evaluation.The incidence and age group distribution of each degenerative grade were recorded.The correlation between the degeneration of intervertebral disc and facet joint with the age and the degeneration sequence were analyzed.Results The lumbar disc degeneration and lumbar facet joint degeneration were positively correlated with the age increase(r=0.56,0.62,P<0.05).The lumbar facet joint degeneration rate in the patients aged less than 45 years old was greater than the lumbar disc degeneration rate,however the lumbar disc degeneration rate in the patients aged≥45 years old was greater than lumbar facet joint degeneration rate.Conclusion Lumbar intervertebral disc and facet joint degeneration closely correlated with the age.The lumbar facet joint degeneration is predominant in the early stage and the lumbar intervertebral disc degeneration is predominant in the later stage.
