慢性腰背痛病变的相关CT影像分析

目的探讨慢性腰背痛病变的相关CT影像的临床应用价值。方法对164例慢性腰背痛患者经CT诊断或手术证实或随访后查明病因者的CT资料进行回顾性分析。结果164例中椎间盘退变致椎间盘程度不等膨出148例,占90.24%:椎间盘突出129例,占78.66%;骨性椎管狭窄33例,占20.12%;退行性腰椎滑脱14例,占8.5%;后纵韧带骨化或钙化26例,占15.85%;黄韧带肥厚22例,占13.41%。结论腰椎间盘病变是引起慢性腰背痛的主要原因,具有典型的CT影像改变,椎管狭窄或侧隐窝狭窄,后纵韧带骨化或钙化也是引起慢性腰背痛的原因之一,正确分析其CT影像特征,对于指导临床治疗,具有重要的意义。

A related study of the CT imaging of the chronic low back pain

Objective To study the clinical application of the C T imaging in patients with chronic low back pain. Methods CT images we re retrospectively analyzed in 164 cases of chronic low back pain. All the cases were diagnosed with CT imaging, or confirmed by operation, or pr oved in follow-up. Results Intervertebral disc bulging in different le vel as a result from the degeneration of the disc was found in 148 cases( 90.24% ) out of 164. Disc protrusion was presented in 129 cases( 78.66% ) . Bony narrowing of the spinal canal was revealed in 33 cases( 20.12% ) . Degenerative lumbar spinal instability yielded in 14 cases( 8.5% ) . O ssification or calcification of posterior longitudinal ligament was seen in 26 cases( 15.85% ) . Thickening of ligamenta flava was shown in the 22 eases( 13.41% ) . Conclusion Chronic low back pain is mainly cau sed by the disorders of the intervertebral disc, which has typical CT fin dings: narrowed spinal canal or lateral recess. Ossification or calcificat ion of posterior longitudinal ligament also plays a role in low back pain . An accurate interpretation of the CT images is essential for the clinical management.
