SUMMARY OF BACKGROUND DATA
The association between the facet tropism and the development of lumbar disc herniation has been studied; however the results remain controversial.
OBJECTIVE
To determine the association between the facet tropism and the development of lumbar disc herniation.
STUDY DESIGN
A cross-sectional study.
MATERIAL AND METHOD
MRI of 34 patients with lumbar disc herniation was evaluated. Two orthopedic surgeons measured facet joint angle and determined the degenerative status of L3-4, L4-5, and L5-SI. Facet tropism was defined as the difference between the angle of the right and left facet more than 5 degrees.
RESULTS
The average difference of facet joint angle of HNP group was higher than normal group in the same level. There was no statistically significant correlation between the facet tropism and lumbar disc herniation.
CONCLUSION
These results do not indicate any relationship between the facet tropism and lumbar disc herniation.
背景数据总结
小关节不对称与腰椎间盘突出症发生之间的关联已被研究；然而结果仍存在争议。
目的
确定小关节不对称与腰椎间盘突出症发生之间的关联。
研究设计
一项横断面研究。
材料与方法
对34例腰椎间盘突出症患者的MRI进行评估。两名骨科医生测量小关节角度并确定L3 - 4、L4 - 5和L5 - S1的退变状态。小关节不对称定义为左右小关节角度差异超过5度。
结果
腰椎间盘突出症组在同一节段的小关节角度平均差异高于正常组。小关节不对称与腰椎间盘突出症之间无统计学显著相关性。
结论
这些结果并未表明小关节不对称与腰椎间盘突出症之间存在任何关系。
