摘要
采用腰椎应力摄片（站立和拉伸位），通过数学式计算出“应力滑移率”（Ｓｔｒｅｓｓｓｌｉｐｐａｇｅｒａｔｅ，ＳＳＲ），发现应力滑移率与临床症状和体征成正比。用这一概念可指导脊柱滑脱的治疗。ＳＳＲ≥３０％的腰椎峡部裂并滑脱１８例，采用了轴向牵引复位、Ｓｔｅｆｅｅ钢板两钉固定、后外侧植骨融合，按Ｓｔｅｆｆｅｅ评定标准１００％恢复到５级。ＳＳＲ＜３０％１２例中保守治疗４例，椎板切除植骨融合８例，５例达５级，３例达４级。
Taking stress films of lumbar spine in erect and stretched position and calculating the stress slippage rate (SSR), We found that symptoms and signs of spondylolisthesis were directly propportional to SSR. We used SSR to guide the treatment of spondylolisthesis. 18 patients of spondylolisthesis with slippage (SSR ≥30%)received reduction by axial traction, fixation with Steffee steelplate of two screws and grafting bone fusion in the posterolateral. Assessed according to Steffee' s criterion, 100% of the patients recovered to Grade Ⅴ. Of the other 12 patients (SSR<30%),4 received conservative treatment ,8 submitted laminectomy. 5 patients recovered to Grade Ⅴand 3 to Grade Ⅳ.Author' s address (Department of Spinal Surgery, Wendeng City Orthopadic,Shadong,264400 )
