颈椎节段性不稳的分型诊断及标准初探

为探讨颈椎节段性不稳的类型井对临床治疗和预防提供依据，根据569例伴有节段性不稳的颈椎病患者的临床特点和影像学特征，将其分为前后滑移型（19例占33．9％）；轴向旋转型（108例占19％）；左右侧摆型（17例占3％）；环枢不稳型（68例占11．9％）；混合型（183例占32．2％）。发现前后滑移和轴向旋转是颈椎节段性不稳定的主要形式，纠正和预防颈椎的前后滑移和轴向旋转错位是防治此类颈椎病的重要措施。

Diagnosing Study on Cervical Segmental Spinal Instability

The purpose of this study was to determine the types of cervical segmental spinal instability.Analysing 569 cases of cervical segmental spinal instability, we found that these cases could be classified into five types by means of the clinical symptoms and the imaging examination. Type 1, displacement toward the front or rear (33. 9% ). Type 2, rotative displacement at the axis (19 % ). Type 3, side rotation on left or right (3% ). Type 4, the atlanto-axial instability (11. 9 %). Type 5, complex type (32. 2% ). Type 1 and Type 2 are the main types. The standard of diagnosis on each type was studied preliminaryly. We treated the patients direetly according to the classification. Excellent and good results have been obtained in all of the patients in the series.
