Intervertebral bone graft fusion and SRS pediclescrewsystem for treatment lumbar spondylolis-thesis

目的 探讨运用 Spondylolisthesis Reduction System (SRS)提拉复位系统加环锯取髂骨于椎体间行单侧或双侧植骨融合治疗峡部不连性腰椎滑脱症。方法 临床共治疗 43例腰椎峡部不连性滑脱病人 ,按手术复位 ,症状改善 ,骨性融合 ,内固定材料牢固情况进行疗效评价。结果 43例患者获得 1～ 5年 (平均 3年 2个月 )随访 ,按我们自拟疗效标准 ,优 3 3例 ,良 7例 ,可 3例 ,无症状加重病例。完全复位 3 8例。无内固定松动断裂发生。结论 环锯椎间植骨融合加 SRS系统 ,能达到很好的复位及牢固的固定 ,从而达到椎间的骨性融合。手术操作简便 ,效果满意 ,如能采取双侧椎间同时植骨 ,增加融合面积 ,效果更佳。

Objective To assess SRS elevating-pull reduction system and intervertebral circular saw iliac bone graft fusion in single or double for surgical treatment of lumbar spinal spondylolisthesis associated with isthmic spondylolysis.Methods 43 patients with lumbar spinal spondylolisthesis associated with isthmic spondylolysis were evaluated for spondylolisthesis reduction,symptom improvement, intervertebral bone fusion,internal fixation.Results The patients were followed up from 1 to 5 years (average 3 years and 2 months) in 43 patients. According to ourcriterion,excellent results were 33 patients,good in 7. No patient showed worse.Spondylolisthesis were completely reduced in 38 patients.Interverbral iliac bone fusion were completely obtained in 43 patients.No internal fixation breakage was found.Conclusion Circulas saw intervertebral bone graft fusion and SRS internal fixation system are the key of treatment.Complete reduction and firm internal fixation improve the symptoms of patients.Excellent outcome was obtained if double intervertebral bone grafts fusion and largery fusion area were applied .
