目的:探讨可能影响退变性腰椎滑脱融合术后远期疗效的相关因素.方法:回顾性分析62例行后路减压复位融合内固定术的退变性腰椎滑脱患者5～9年的随访资料.以JOA评分改善率作为判断疗效的指标,并以此分为疗效优良组和疗效欠佳组.采用单因素筛选和Logistic回归分析患者年龄、性别、体重指数、合并糖尿病、病程、术前滑脱率、术前...

Multivariate analysis of factors affecting long-term outcomes of degenerative lumbar spondylolisthesis treated with posterior fusion

Objective： To analyze factors affecting long-term outcomes of degenerative lumbar spondylolisthesis treated with posterior fusion.Methods： Retrospective study was conducted to analyze the followed up data of 62 patients with degenerative lumbar spondylolisthesis that underwent posterior fusion treatment.The followed up data ranged from 5-9 years.According to JOA scores,these patients were categorized as good outcomes group and poor outcomes group.Age,sex,body mass index（BMI）,diabetesmellitus,duration of symptoms,preoperative slippage rate and preoperative JOA score,fusion segments,fusion method,postoperative reduction rate,increase of intervertebral height and angle,as well as follow-up duration were analyzed using univariate analysis and binary logistic regression methods.Results： Univariate analysis of preoperative JOA score,duration of symptoms,diabetesmellitus,BMI and fusion segments showed significant influence on the long-term prognosis（P〈0.05）.The results of binary logistic regression indicated that preoperative JOA score and duration of symptoms were the statistically significant factors affecting clinical outcomes（P〈0.05）.Conclusions： Many factors can affect long-term outcomes of degenerative lumbar spondylolisthesis that were treated with posterior fusion.General good long-term results can been achieved through complete intraoperative decompression,fit reduction,good fusion and fixation.
