腰椎间盘突出X线平片和CT诊断及手术对照(附118例分析)

目的：提高Ｘ线平片腰椎间盘突出（ＬＤＨ）诊断正确率。方法：１１８例ＬＤＨ手术病例全部摄腰椎正侧位片和ＣＴ扫描，然后加以对照分析。结果：腰椎椎间隙前窄后宽或前后等宽；椎体后下和后上缘的唇样变及骨赘形成有明确定位意义。椎体上下缘凹陷和硬化征是腰椎间盘突出最常见征象，也是本文回顾性分析新的见解。结论：充分认识腰椎间盘突出Ｘ线平片特征，能够提高Ｘ线平片的诊断正确率。

A Comparative Study on the Plain Radiographs,CT Diagnosis and Surgical Findings of LDH

Objective: TO improve the correct diagnostic rate by plain radiographs in lumbar disc herniation(LDH). Methods: There were 118 cases confirmed by operation.The AP and lateral view plain films and CT scan were taken in all cases,then we compared the radiological and surgical findings. Results: The following signs had distinct value for localizing LDH:The lumbar vertebral spaces became narrower at the anaterior part than the posterior part or the width of anterior part was equal to posterior part;the posterior margin of vertebral body existed hypertrophic changes with lipping further spur formation on the lipping.The concave and sclerotic signs on the upper and lower margin of the vertebral body were the most common signs of LDH and were also a new opinion of LDH. Conclusion: By fully understanding the plain radiograph characters of LDH can increase the correct diagnosis rate.
