The Treatment of Steuosis of Lumbar Vertebral Canal by Opening-door Plasty of Lumbar Vertebral Canal

我院自１９９２年８月采用腰椎管开门成形术治疗腰椎管狭窄症５４例．男３８例，女１６例．年龄３２～６３岁，平均４８岁．病程５个月～８年，平均３年９个月．５４例术前都进行Ｘ线摄片检查，ＣＴ或ＣＴＭ检查。手术方法，采用单开门式３７例，双开门式１７例．全部经过门诊定期复查，随访时间最短６个月，最长３年２个月，平均１年４个月。术后半年Ｘ线摄片复查见椎板及小关节融合良好，腰腿痛症状减轻或消失，下肢行走有力。根据优、良、可、差，四级评分标准。５４例中，优３８例，良１０例，可５例，差１例。优良率占８８．９％。

In order to maintain the stability of lumbar vertebrae and minimize the postopera tive adhesion. We have treated 54 cases of stenosis of lumbar vertebral canal using method of opening-door plasty,of which 38 cases are male and 16 female. The ages range from 32 to 63 years old averaging 48. All the 54 cases underwent X ray, CT or CTM examination before operation. 37 cases were treated by unilateral opening-door plasty,while 17 by bilateral opening-door plasty. All cases were followed up and the duration averaged 1 year and 4 months. Half year after the op- eration,X-ray film showed the fusions of lumbar vertebral lamina and facet joints were good. The signs of lumbar and lower extremities were alleviated or disappeared. The patients could walk energeticly. The rate of excellent and good was 88. 9%.
