背景：据我们所知，没有对在老年患者行后路椎体间融合术的手术结果任何报告。
BACKGROUND: We are aware of no reports on the surgical results of posterior lumbar interbody fusion in elderly patients.
目的：比较后路椎体间融合(PLIF)联合后外侧融合(PLF)与单纯PLIF治疗腰椎退行性疾病的疗效。
Objective To study the clinical outcomes of posterior lumbar interbody fusion (PLIF) with and without posterolateral lumbar fusion (PLF) in treatment of degenerative lumbar disease.
结论：尽管实现了节段间的后路椎间融合，椎体缺血性坏死仍会在没有创伤的情况下发生。
Conclusion. Despite solid posterior fusion segments, avascular necrosis of a vertebral body developed without trauma.
结论后路减压并椎体间融合是治疗退变性腰椎管狭窄症的有效方法。
Conclusion Posterior lumbar spinal canal decompression and interbody fusion is an effective method for the treatment of degenerative lumbar spinal stenosis.
