青年人下颈椎不稳症临床与X线影像分析

Clinical and X-ray analysis of lower cervical spine instability in young people

目的认识青年人下颈椎不稳(无骨质异常)的临床与影像表现。方法对下颈椎不稳症21例均采用正侧双斜位及摄X线动态颈椎侧位过曲过伸片。结果21例动态颈椎侧位过曲过伸片椎体均有不同程度的移位,均大于2mm,多见于C3,C4,C5。结论有临床症状的青年人动态颈椎侧位过曲过伸片可提示或明确本病的诊断。

Objective To understand the clinical and imaging manifestations of lower cervical spine instability in young people. Methods X-ray posteroanterior, lateral, double-oblique and dynamic lateral overflexional and overextensive views were performed on 21 patients. Results Shift of vertebral bodies was found on dynamic lateral overflexional and overextensive views in all cases. The mean distance of shift was 2 mm and the most common locations were C3,C4 and C5. Conclusion X-ray dynamic lateral overflexional and overextensive views have predictive and definitive value for the diagnosis of lower cervical spine instability in young people with clinical symptoms [
