To investigate the relationship between radiographic signs of subluxation in the cervical vertebrae and their clinical diagnostic value.
Controlled, clinical study.
Institute of Clinical Anatomy and Biomechanics and NanFang Hospital of the First Military Medical University, Guangzhou, China.
Eighty-seven subjects with cervicodynia and 21 asymptomatic volunteers.
Radiological signs of subluxation from anteroposterior, lateral, open-mouth and dynamic radiographs of the cervical vertebrae of the subjects were measured and analyzed.
The right and left odontoid lateral mass interspace, divergence of the spinous processes, sign of double contour and position of odontoid process were studied.
The bilateral odontoid lateral mass interspaces were asymmetrical in most cases, and the divergence of spinous processes, sign of double contour and position of odontoid process were also common. Cervical vertebrae C5, C4 and C6 showed no special variations.
There was little evidence to support the contention that signs of subluxation in the cervical vertebrae are of diagnostic significance. Subluxation should be defined in two ways: as a purely roentgenological diagnosis and as a combination of roentgenological signs with clinical signs.
探讨颈椎半脱位的影像学征象与其临床诊断价值之间的关系。
对照临床研究。
中国广州第一军医大学临床解剖与生物力学研究所及南方医院。
87例颈痛患者和21名无症状志愿者。
对研究对象颈椎的前后位、侧位、开口位及动力位X线片上的半脱位影像学征象进行测量和分析。
研究左右齿突侧块间隙、棘突间距、双轮廓征及齿突位置。
多数情况下双侧齿突侧块间隙不对称，棘突间距、双轮廓征及齿突位置异常也较常见。C5、C4和C6颈椎未见特殊变异。
几乎没有证据支持颈椎半脱位征象具有诊断意义这一观点。半脱位应从两种方式进行定义：作为一种单纯的放射学诊断以及作为放射学征象与临床征象的结合。
