[摘要] 目的：探讨PLIF手术和减压加后外侧植骨两种手术方式在治疗退行性腰椎滑脱手术的临床疗效。方法：回顾性分析2001年2月～2009年2月在我院治疗的退行性腰椎滑脱患者41例，其中减压伴后外侧融合患者20例，接受PLIF手术患者21例。术前评价患者的VAS评分、滑脱等级、年龄、性别、体重指数，末次随访时评价患者的VAS评分，并对患者的术后临床效果进行评价。结果：两组之间的术前VAS评分、滑脱等级、年龄、性别、体重指数无明显的统计学差异(P>0.05)。末次随访时减压组VAS评分平均为(2.1±0.2)，内固定组VAS评分平均为(1.9±0.3)，两组之间的VAS评分无明显统计学差异(P>0.05)。按照疗效评定标准，减压组：优11例，良6例，可2例，差1例；内固定组：优13例，良6例，可1例，差1例。经Mann-Whitney U检验，两组之间术后临床效果无明显统计学差异(P>0.05)。结论：PLIF手术和减压伴后外侧植骨两种手术方式在治疗退行性腰椎滑脱术后疗效无明显差异。

[Abstract] Objective: To investigate the feasibility and clinical effect of treatment of degenerative lumbar spondylolisthesis with PLIF and lumbar posterolateral fusion and decompression. Methods: The retrospective analysis of 41 patients with degenerative lumbar spondylolisthesis from February 2001 to February 2009 was carried out. There were 20 patients with lumbar posterolateral fusion and decompression, 21 patients with PLIF. The degree of spondylolisthesis, the visual analogue score (VAS), age, sex, body mass index (BMI) were recorded before operation. All patients had an average follow-up period of 20.8 months. Then VAS and the effect of operation were compared through t-test. Results: All 41 patients had a followed-up. There were no difference between two groups in the degree of spondylolisthesis, the visual analogue score (VAS), age, sex, body mass index (BMI) (P>0.05). VAS scale was(2.1±0.2) at last follow-up in PLIF group and(1.9±0.3)in decompression group. There was no significant difference in VAS scale between two groups. 4-grade scale was excellent 11, good 6, fair 2, bad 1 in decompression group and excellent 13 good 6, fair 1, bad 1 in PLIF group; There was no significant difference in 4-grade scale between two groups (P>0 ......
