摘　　要：目的：探讨正常成人腰椎关节突关节角和关节面曲率及其临床意义。方法120例非腰椎疾病患者,进行腰椎多层螺旋CT 扫描多平面重建,测量各节段腰椎关节突关节角度和关节面曲率,比较不同年龄、性别及腰椎不同节段上述指标的差异。结果①相同腰椎节段关节突关节角,男女性别之间及不同年龄组之间差异均无显著性（P 值均〉0.05）；各腰椎节段关节突关节角的差异有显著性（P〈0.05）。②相同腰椎节段关节突关节的关节面曲率,男女性别之间及不同年龄组之间差异均无显著性（P 值均〉0.05）；各腰椎节段的关节突关节的曲率有显著性差异（P 〈0.05）,L3~L4节段关节面曲率最大（22.1°±6.0°）。结论正常成人不同腰椎节段的关节突关节角及关节面曲率均不同,其在维持腰椎稳定性方面的作用也不同。Objective To study the angle and articular facet curvature of lumbar zygapophyseal joints in adults.Methods The lumbar zygapophyseal joints in 120 healthy subjects without lumbar diseases were detected using spiral CT and mutiple planner re-construction.The angle and articular facet curvature of zygapophyseal joints were measured.The differences in the measured param-eters between male and female or different age groups were compared.Results ①There were no significant differences in the angle of the same lumbar zygapophyseal joints between males and females or different age groups （P 〉0.05）;however,the significant differences in the angle between different lumbar segments were found （P 〈0.05）.②There were no significant differences in articu-lar facet curvature of the same lumbar zygapophyseal joints between males and females or different age groups （P 〉0.05）;however, there were significant differences in the curvature between different lumbar segments （P 〈0.05）.The maximum articular facet cur-vature of L3-L4 was 22.1°±6.0°.Conclusion The angle and articular facet curvature of lumbar zygapophyseal joints varies from different lumbar segments with different contributions for the lumbar stability.
