LUMBAR INTERBODY FUSION
COMPARISON OF POLYETHERETHERKETONE CAGES WITH FEMORAL CORTICAL BONE ALLOGRAFT AS A SINGLE PIECE INTERBODY SPACER IN TRANSFORAMINAL LUMBAR INTERBODY FUSION.
Cutler, A.R., Siddiqui, S., Mohan, A.L., Hillard, V.H., Cerabona, F., Das, K., 2006, Journal of Neurosurgery: Spine 5 (6), pp.534-539.
Study Detail: 39 patients underwent single-level TLIF and in whom either a PEEK cage (I8 patients) or FCA (21 patients) was placed as an interbody spacer were evaluated in a retrospective study.
Radiographically documented fusion occurred in all patients in the PEEK group and 95.2% of those in the FCA group. Pseudarthrosis developed in one patient in the FCA group, and this patient underwent additional surgery. In both groups, the mean lordotic angle changed by less than 2.20 degrees during the postoperative period, and the mean postoperative ODI score was more than 40 points lower than the mean preoperative score. There was no significant difference between the two groups in mean change in lordotic angle (p =0.415) and mean change in Oswestry Disability Index (ODI) score (p =0.491).

Author's Conclusions: Both PEEK cages and FCAs are highly effective in promoting interbody fusion, maintaining postoperative disc space height, and achieving desirable clinical outcomes in patients who undergo TLIF with pedicle screw fixation. The advantages of PEEK cages include a lower incidence of subsidence and their radiolucency, which permits easier visualization of bone growth.

腰椎椎体间融合术
椎间孔腰椎椎体间融合术中聚醚醚酮椎间融合器和股骨皮质骨异体移植物作为单个椎体间隔区的比较
Cutler, A.R., Siddiqui, S., Mohan, A.L., Hillard, V.H., Cerabona, F., Das, K., 2006, 神经外科杂志:脊柱5(6), pp.534-53。
研究详情: 39例患者进行单级椎间孔腰椎椎体间融合术,并对以PEEK椎间融合器(18例患者)或股骨皮质骨异体移植物(21例患者)作为椎体间隔区在追溯性研究中进行评估。
X射线检测显示所有的PEEK组患者和95.2%的FCA组患者中出现了融合。FCA组中有1患者出现假关节,对该患者进行了其他手术。手术后期间,两组患者的平均脊柱前凸角改变小于2.20度,手术后平均ODI值比手术前平均值低40多个点。两个组脊柱前凸角的改变平均值(P=0.415)和Oswestry功能障碍指数(ODI)的变化平均值均(P=0.491)无显著性差异。

作者结论: PEEK椎间融合器和FCAs在用椎弓根螺钉固定进行椎间孔腰椎椎体间融合术的患者中对改善椎体融合、保持手术后椎间盘空间高度和取得符合要求的临床结果方面都有很好的效果。PEEK椎间融合器的优点包括低消退发生率和X光可透性,使骨的生长易于观察。
