目的:探讨无骨折脱位型颈椎“挥鞭样”损伤(WAD)对损伤节段及邻近节段关节突(Facet)关节倾角的影响。方法:2017年8月到2019年12月在郑州大学第一附属医院骨科门诊或急诊就诊的因WAD所致的颈(C)5/6椎间盘突出症患者40例(排除颈椎骨折脱位)，选取同期以颈部不适就诊的非颈椎病患者40例，分为外伤组和对照组。测量所有患者C4～C7的Facet关节倾角，并对C4～C7椎间盘退变和关节突退变的分级进行统计分析。采用重复测量的方差分析、秩和检验、n t检验和n χ2检验等。n 结果:重复测量数据的方差分析结果表明：C4～C7每个颈椎Facet关节倾角在两组内椎间比较差异有统计学意义(n F椎间＝45.630，n P椎间0.05)，但差异均无统计学意义(n P>0.05)；Mann-Whitneyn U秩和检验显示：外伤组C5/6椎间盘的退变与对照组比较更为严重(n UC5/6＝12，n P0.05)；Kendall’s tau-b秩相关分析表明：外伤组C5椎体Facet关节倾角与C5/6椎间盘退变程度呈负相关(n rs＝-0.842，n P0.05). Mann-Whitney U rank sum test shows: Compared with the control group, the C5/6 intervertebral disc degeneration in the trauma group was more severe than that in the control group. The difference was statistically significant (n UC5/6=12, n P0.05). Kendall’s tau-b rank correlation analysis showed that: The C5 vertebral Facet joint inclination angle of the trauma group was negatively correlated with the degree of C5/6 intervertebral disc degeneration (n rs=-0.842, n P<0.05).n Conclusion:Facet joint angle of the upper and lower vertebral body became smaller after WAD. The stability of the injured segment is decreased. But it has little effect on the Facet joint inclination angle of the adjacent segment. WAD may immediately aggravate intervertebral disc degeneration in injured segments. However, influence of WAD for facet degeneration needs to be determined by long-term follow-up.
