经皮腰椎间盘髓核切吸术疗效分析

目的　探讨CT水平面图像腰椎间盘突出角度、矢状面图像突出髓核中心位置与APLD疗效的关系。方法　将 49例经皮切吸术治疗的病例分为两组。A组 :CT水平面图像 ,椎间盘突出角≥ 1 1 0°,矢状面图像突出髓核中心位于该节段椎间盘间隙高度内 2 2例 ;B组 :CT水平面图像 ,椎间盘突出角 <1 1 0° ,矢状面图像突出髓核中心在该节段椎间盘间隙高度之外 2 7例。结果　 49例随访 1 6～ 35个月 ,平均 2 2 9个月。A组有效率 90 91 % ,B组有效率 59 2 6% (P <0 .0 5)。结论　通过对CT扫描水平面图像腰椎间盘突出角度、矢状面图像突出髓核中心位置的仔细分析能基本预测APLD的疗效。

Evaluation of effect of automatic percutaneous lumbar discectomy

Objective To study the relations between the efficacy of APLD and the angle of the lumbar disc herniation on the horizontal CT films and the central location of the herniated disc nucleus pulposus on the sagittal CT films.Methods Forty nine cases of APLD were classified into two groups.Twenty two cases in group A had the angle of the lumbar disc herniation on the horizontal CT films more than or equal to 110 degrees,and their central location of the herniated disc nucleus pulposus on the sagittal CT films was in the vertical height of the crevice of its corpur vertebrae.Twenty seven cases in group B had the angle of the lumbar disc herniation in the horizontal CT films less than 110 degrees,and their central location of the herniated disc nucleus pulposus in the sagittal CT films was out of the vertical height of the crevice of its corpur vertebrae.Results Forty nine cases were followed up for 16 months to 35 months,with an average of 22.9 months.The effective rate was 90.91% in group A and 59.26% in group B( P <0.05).Conclusion The efficacy of APLD can be primarily predicted by analyzing carefully the angle of the lumbar disc herniation on the horizontal CT films and the central location of the herniated disc nucleus pulposus on the sagittal CT films.
