目的观察比较腰椎融合(PLIF)与非融合(腰椎椎弓根螺钉加弹性棒)内固定术对邻近阶段退变的影响.方法收集郑州大学第一附属医院2009年6月至2012年10月接受腰椎椎弓根螺钉加弹性棒内固定术(非融合组)和PLIF术(融合组)两种方法治疗腰椎退行性疾病患者30例.随访2～3年,给予复查磁共振成像(MRI)观察邻近阶段退变.结果腰5/骶1阶段术前、术后Woodend评分比较差异无统计学意义(P＞0.05)；腰3/4阶段术前、术后12个月及24个月比较差异无统计学意义(P＞0.05),术后36个月融合组(1.45 ±0.04)与非融合组(1.14 ±0.03)评分差异有统计学意义(P＜0.05),且融合组术前与术后36个月评分差异有统计学意义(P＜0.05).结论非融合术对腰椎各阶段活动影响较小,一定程度上减缓了邻近阶段发生退变的可能.

Objective To compare the influence between fusion (PLIF) and non-fusion (lumbar pedicle screws combined with elastic rod fixation) for lumbar in adjacent stages of degeneration.Methods From June 2009 to October 2012,a total of 30 patients with lumbar degenerative disease were treated.The patients in fusion group were treated by PLIF (n =16),and those in non-fusion group were treated by lumbar pedicle screws combined with elastic rod fixation (n =14).During a follow-up period of 2 to 3 years,magnetic resonance imaging (MRI) re-examination was done to observe degeneration in adjacent stages.Results Woodend indexes (L5/S1) before and after surgery in fusion group and non-fusion group had no statistically significant difference (P ＞ 0.05) ; Woodend indexes (L3/L4) before,and 12 months and 24 months after surgery in fusion group and non-fusion group had no statistically significant difference (P ＞0.05),but there was significant difference between fusion group (1.45 ± 0.04) and non-fusion group (1.14 ± 0.03) 36 months after surgery (P ＜ 0.05).At the same time,there was significant difference before and 36 months after operation in fusion group.Conclusion The surgery of non-fusion can less affect the lumbar activity in different stages,to a certain extent slowed down the degeneration of adjacent stages.
