为探讨诊断自发性环枢椎脱位的几种X线测量价值,本文对42例患者和100例年龄相当者的正常X线片进行测量分析。结果表明:环齿前距、环枢关节间隙不等、齿突与侧块间距差及本文提出的环枢棘突角是诊断本病的主要依据;环齿间距/环枕线、齿突后倾角不如前述4种的价值高;颈椎生理弧度改变等只能作为诊断的参考,但强调颈椎前凸增大应注意脊髓损害问题。
In order to explore the value of several X-ray measurements in the diagnosis of spontaneous cycloaxial vertebral dislocation, we measured and analyzed the normal radiographs of 42 patients and 100 age-matched patients. The results show that: the distance between the anterior ring of the ring teeth and the joints of the ring-and-ring joints, the difference of the distance between the odontoid and lateral masses and the spinous process angle presented in this paper are the main bases for diagnosing this disease; Inclination is not as high as the value of the aforementioned 4; changes in physiological curvature of the cervical spine can only serve as a diagnostic reference, but stressed that cervical enlargement should pay attention to spinal cord injury.
