摘　　要：目的比较在双侧椎弓根内固定情况下,腰椎后外侧横突间植骨融合、应用融合器行后方椎间融合治疗短节段腰椎不稳的临床效果。方法回顾分析65例融合内固定术治疗的短节段腰椎不稳病人资料,对患者术前及随访时症状进行JOA评分,比较PLF术和PLIF术式术前及随访时JOA评分改善程度、手术出血量、手术时间、术后并发症和手术节段融合效果。结果全部患者均顺利完成手术,PLIF组随访的39例患者中,植骨达到100%融合,PLF组随访的12例患者中,确切融合达到41.67%。结论短期随访中,PLF术在患者症状改善情况上与PLIF术相近,融合效果较PLIF术差。Objective To investigate the clinical outcome of the treatment of pest lateral lumbar fusion（ PLF）, pest lumbar interbody fusion with wedge- shaped cage（PLIF） in short -segmental unsettled （internal bilateral internal fixation is used mall cases）. Methods The clinical records of 65 patients with short - segmental unsettled treated by fusion techniques with internal fixation are investigated retrospectively. The change of JOA score between pre - operation and pest operation, operation time, blood loss, complications and fusion effects in radiographs were measured and checked by statistic method. Results All the patients were operated safely. In the 39 available radiographs of PLIF group, the fusion rate is 100% and in the 12 radiographs of PLF group, the fusion rate is 41.67%. Conclusion The fusion rate of PLF technique is lower than PLIF technique; the incidence of pest operational low back pain is statistically the same with the two techniques.
