腰椎间盘突出症快速牵引后CT随访观察

CT follow-up on lumbar disc hernias after rapid traction

目的:观察快速牵引治疗腰椎间盘突出症突出物的 CT 变化。方法:32例中央型和侧后型突出患者,随访时间3个月～4年,平均12.04个月。采用 AB×CD/EF×GH 比值法,在 CT 片上测量突出物。结果:32例腰椎间盘突出症无一例突出物完全消失,其中27例突出物缩小占84%;5例突出物稍增大占16%。比值测定:侧后型20例治疗前为0.183 0±0.066 3,随访时为0.130 3±0.061 8(P<0.05);中央型12例治疗前为0.233 7±0.085 8,随访时为0.157 2±0.074 9(P<0.05)。结论:快速牵引可使突出物部分缩小,但不能完全消失。

Objective:The purpose of this study was to assess the change of protruding material in lumbar disc hernias after rapid traction.Methods:32 cases of lumbar disc hernia who suffered from the medial or post-lateral protrusion were followed-up three months to four years after rapid traction. The protruding materials were measured on CT screen ,the ratio of AB×CD/EF×GH was adopted.Re- sults:In these patients,none of protruding materials were completely regressed.The protruding materi- als of 27/32 cases were shortened(84%),5 enlarged slightly(16%).The ratio determination in 20 post- lateral hernia patients at pre-treatment and follow-up duration was 0.1830±0.0663 and 0.1300± 0.0618 respectively,in 10 cases with medial protrusion,the ratio was respectively 0.2337±0.0858 and 0.1572±0.0749(P<0.05)at pre-treatment and follow-up period.Conclusion:It is indicated that the rapid traction can shorten the protruding materials,but cannot make it regression completely.While the clinical effect isn't related to the decrease of protruding materials obviously.
