目的：探讨改良后路椎间植骨融合术（PLIF）治疗腰椎退行性疾病的临床效果。方法将186例腰椎退行性病变伴腰腿痛的患者分成两组，分别使用改良 PLIF 和传统 PLIF 治疗。记录所有患者术前、术后 VAS 评分和 JOA 评分。结果两组术后住院时间差异无统计学意义（P ＞0．05），而手术时间及术中出血量改良 PLIF组均优于传统 PLIF 组（P ＜0．05）。患者均获随访，时间6～36个月。JOA 评分：两组术后3个月和末次随访与术前比较差异均有统计学意义（P ＜0．05），术后3个月与末次随访比较差异均无统计学意义（P ＞0．05）。末次随访时两组 JOA 评分、VAS 评分比较差异均无统计学意义（P ＞0．05）。结论改良 PLIF 治疗腰椎退行性疾病可以获得与传统 PLIF 相同的临床效果，且具有手术时间短、术中出血少及组织损伤轻等优点。

Objective To explore the clinical outcomes of modified posterior lumbar interbody fusion (PLIF)in the treatment of degenerative lumbar disease.Methods 186 patients with degenerative lumbar disease were divided into 2 groups and treated with traditional PLIF and modified PLIF respectively.Visual analogue scale (VAS)scores and Japanese Orthopaedic Association (JOA)scores were recorded before and after the treatment.Results The postop-erative hospital stay was not different (P >0.05 ),but there were significant differences between the 2 groups in terms of operation time and blood loss (P <0.05).The duration of follow-up was range from 6 to 36 months for all the patients.In both modified PLIF group and the traditional PLIF group,JOA score was significantly increased and VAS score was significantly decreased at 3 months after surgery and at the final follow-up as compared with the score before surgery (P <0.05).There was no significant difference in VAS score between 3 months postoperatively and the final follow-up in both groups (P >0.05).Neither was the JOA score (P >0.05).Conclusions Functional outcome of modified PLIF is similar to traditional PLIF technique in the treatment of degenerative lumbar disease.But it has shorter operation time,and less blood loss and tissue damage.
