[Objcctive]To evaluate the 5-ycar follow-up result of posterior lumbar interbody fusion (PLIF) with single segment using autogenous bone of vertebral appendixes.[Methods]From July 2004 to July 2005, Totally 36 cases received PLIF surgery with single segment using autogenous bone of vertebral appendixes.Hospitalized records and X-ray findings at 1, 3, 5 years post-operation were collected and Oswcstry Disability Index (ODD was evaluated to observe the fusion effect and adjacent segment degeneration (ASD).[Results]The postoperative fusion rate were 88.89％, 94.44％ and 97.22％ respectively in the first, third and fifth year.The rate of lumbar discomfort was 16.67％.The difference was significant between preopcrativc and postoperative ODI (P＜0.01).The difference was not significant among postoperative ODI in the first, third and fifth year postopcrativcly.The rate of ASD was 33.33％ in the fifth year postopcrativcly.The rate of ASD with the ODI raise was 5.56％.[Conclusion]PLIF with single segment using autogenous bone of vertebral appendixes is an effective method for lumbar diseases.The clinical efficacy was satisfying after 5-ycar postoperative follow-up.The ASD was mostly the change of imagcology.There was no corrclationship between ASD and clinical efficacy.%[目的]评价腰椎后路单节段椎间融合术应用自体附件骨融合的融合率及术后中远期的临床疗效.[方法]选择自2004年7月至2005年7月在本院接受腰椎后路内固定、单节段椎间植入自体附件骨融合术,并且获得完整随访的36例患者进行回顾性分析.通过随访获得其术前、术后1年、3年、5年的影像学资料和术后康复情况资料,观察植骨融合情况及邻近节段退变(ASD)情况,并用Oswestry功能障碍指数(Oswestry disability index,ODI)进行评分,评价临床疗效.[结果]术后1年融合率为88.89%,术后3年融合率94.44%,术后5年融合率为97.22%;术后5年部分患者遗留腰部僵硬、下坠感、腰痛等不适症状,发生率16.67%;术后1年、3年、5年ODI评分比术前均有显著性降低(P＜0.01),术后1年、3年、5年的ODI评分两两比较无显著性差异(P＞0.05);术后5年邻近节段退变发生率33.33%,具有相应症状、体征及ODI评分增加的ASD发生率为5.56%.[结论]应用后路自体附件骨椎间植骨融合内固定术治疗单节段腰椎疾患融合率高,术后中远期ODI评分临床效果好;术后5年ASD多是影像学上的变化,而与临床疗效间无明显相关性.
