Various intervertebral spacers with or without posterior instrumentation use pedicle screw fixation in posterior lumbar interbody fusion (PLIF). Recently we harvested an autologous cortical bone graft from a spinous process by en bloc resection and inserted it between two intervertebral spacers during PLIF surgery. Due to better balance, this procedure provides greater mechanical strength, larger contact area, and better bilateral restoration of disc height than PLIF using intervertebral spacers only, and there is no need to take a bone graft from the iliac crest. This technique appears to result in effective spinal fusion in PLIF surgery.
各种带或不带后路内固定装置的椎间融合器在腰椎后路椎间融合术（PLIF）中使用椎弓根螺钉固定。最近，我们通过整块切除从棘突获取自体皮质骨移植，并在PLIF手术期间将其插入两个椎间融合器之间。由于更好的平衡性，该手术比仅使用椎间融合器的PLIF提供更大的机械强度、更大的接触面积以及更好的椎间盘高度双侧恢复，并且无需从髂嵴取骨。该技术似乎能在PLIF手术中实现有效的脊柱融合。
