改良腰椎后路椎体间植骨融合术的临床疗效分析

目的对比研究改良腰椎后路椎体间植骨融合术(PLIF)与经椎间孔入路腰椎椎间植骨融合术(TLIF)治疗腰椎退行性疾病的临床疗效。方法选择本院2008年1月—2009年6月收治的52例腰椎退行性疾病患者,随机分为改良PLIF组30例及TLIF组22例,对比2组患者术前、术后第1周,术后第6、12个月腰、腿视觉模拟评分(VAS)及日本骨科学会(JOA)评分,以及术后并发症情况。结果 52例患者切口均一期愈合。2组患者临床疗效及术后并发症发生率无显著差异(P>0.05)。结论改良PLIF减少了术后并发症,提高了手术优良率和手术成功率,且降低了术后翻修率,是一种安全、可靠和可行的方法。

Clinical curative effect of modified posterior lumbar interbody fusion

Objective To evaluate the clinical outcome of modified posterior lumbar interbody fusion(PLIF) and transforaminal lumbar interbody fusion(TLIF) with pedicel screw system for several lumbar degenerative disease.Methods From January 2008 to June 2009,52 patients with lumbar spine of degenerative disease were divided into modified PLIF group(n=30) and TLIF group(n=22).The clinical outcome and fusion rate in these two groups were compared.Results All patients had primary healing incision.There was no significant difference in clinical curative effect and postoperative complications between the two groups(P>0.05).Conclusion Modified PLIF can reduce the postoperative complications,improve the excellent rate and success rate,reduce the postoperative overhaul rate.It′s a safe,reliable and feasible method.
