DR在腰椎不稳诊断中的应用

Application of DR in diagnosis of lumbar instability

目的:探讨数字化X线摄影(digital radiography,DR)在腰椎不稳诊断中的应用,为临床提供可靠诊断、治疗的依据。方法:对198例可疑腰椎不稳的腰腿痛患者进行常规DR腰椎正侧位片、过伸过屈位片检查,分析腰椎椎体向前、后移位,椎体成角和棘突分离或相互靠近情况。结果:根据国外White和Panjabi提出的方法,筛查出35例腰椎不稳患者。结论:与常规腰椎正侧位、斜位片相比,腰椎过伸过屈位片可发现腰椎失稳和功能改变,可对临床提供治疗依据及观察治疗前后疗效对比起到一定的指导作用。

Objective To apply DR to the diagnosis of lumbar instability. Methods Totally 198 patients suspected with lumbar instability underwent routine lateral side DR radiograph and examination of flexion-extension position to analyze the forward and backward displacements of the lumbar. Results Totally 35 patients with lumbar instability were determined based on the method proposed by White and Panjabi. Conclusion Film of flexion-extension position gains advantages over films of lateral position and oblique position in lumbar instability and malfunction, and thus helps for clinical diagnosis and efficacy observation.
