摘要
从2000年到2008年80例腰椎不稳患者经过双侧椎板减压并碎骨块椎体间植骨融合，采用椎弓根钉内固定。腰椎不稳通过X、CT或MK，了解是否合并存在椎间盘撕裂或椎管狭窄情况；76例（95％）患者达到坚强的融合，有4例（5％）融合失败。没有病人抱怨术后术口疼痛。而且无伤口感染；植骨窗的良好建立和椎板减压过程中的碎骨块的去软组织化是融合成功的关键因素；达到的融合率与自体髂骨块移植达到的融合率相当。它是一种行椎体间融合所需的自体髂骨块移。植良好的代替品。
We retrospectively reviewed the outcome of posterior lumber interbody fusion （PLIF） in 80 patients with lumbar spondylolisthesis （IS）, who had undergone posterior decompression laminectomy with foraminotomy and PLIF using laminectomy bone chips as bone graft, with reduction of the slipped vertebra with transpedicle screws, between 2000 and 2008. Diagnosis of LS was confirmed by plain lumbar radiography, with computed tomography （CT） scan or magnetic resonance imaging （MRI） studies performed to confirm an associated condition, such as ruptured disc and spinal stenosis. The outcome of spinal fusion was good with 76 （95%） patients attaining solid fusion, while failed fusion was noted in 4 （5%） patients. None of our patients complained of excessive postoperative wound pain. Additionally, no complications, such as wound infection, were encountered. Proper decortication of the posterior paravertebral gutters with an osteotome and removal of all soft tissues from the laminectomy bone chips are significant factors contributing to the successful outcome of the laminectomy bone chips in PLIF. The fusion rate obtained with this type of autogenous bone graft is comparable to that of the iliac bone crest autogenous graft; hence, it is a good substitute for the iliac crest bone autogenous graft in performing PLF in treating lumbar spondylolisthesis.
