| 摘 要： | 目的:研究颈椎单侧关节突交锁的旋转角度及影像学特点,为早期诊断提供依据。方法:4具C1-T1段甲醛浸泡成人颈椎标本,2男2女,年龄28～40岁。试验前摄X线片和行CT扫描,用自制夹具分别固定C2-C4、C5-T1,并施加屈曲和旋转暴力,使标本分别在侧屈旋转、前屈旋转下模拟颈椎单侧关节突交锁,并部分模拟肌肉收缩,最后进行影像学分析。结果:颈椎单侧关节突交锁平均旋转角度为19.75°,椎体平均前方移位为3.68mm。以本试验摄片标准,0°、10°、180°、190°时损伤节段下位可见椎间孔;150°、160°、00°、-10°时损伤节段上位可见椎间孔,损伤节段关节突交锁或紊乱。交锁侧前斜位椎间孔变大,对侧前斜位椎间孔变小。CT平扫可见椎体旋转、关节突裸露征、关节突骨折等特点;冠状面三维重建可见双侧不对称;矢状面重建清晰可见关节突交锁。结论:X线和CT表现都可作为颈椎单侧关节突交锁的诊断依据,CT表现能更好地诊断单侧关节突交锁。 |
