The radiographs of 35 consecutive adult patients with isthmic spondylolisthesis who underwent a transforaminal lumbar interbody fusion (TLIF) with one or two Brantigan carbon fiber cages and pedicle screw instrumentation were evaluated. Anterolisthesis, disk space height, and slip angle were measured in preoperative and postoperative standing neutral radiographs. Anterolisthesis was reduced and disk space height was increased with the TLIF procedure. Average slip angle, however, was not significantly altered. The restoration of lordosis across the listhetic disk space correlated with a more anterior placement of the interbody cage within the disk space. The TLIF technique, performed with the Brantigan cage and pedicle screw instrumentation, appears to be able to restore disk height and reduce forward translation in patients with isthmic spondylolisthesis, but improvement in sagittal alignment is dependent upon anterior placement of the interbody device.
对35例连续成年峡部裂型腰椎滑脱患者的X线片进行了评估，这些患者接受了使用一个或两个Brantigan碳纤维椎间融合器和椎弓根螺钉内固定的经椎间孔腰椎椎间融合术（TLIF）。在术前和术后站立位中立位X线片中测量椎体前移、椎间隙高度和滑脱角。经TLIF手术，椎体前移减少，椎间隙高度增加。然而，平均滑脱角没有显著改变。通过滑脱椎间隙的前凸恢复与椎间融合器在椎间隙内更靠前的放置相关。使用Brantigan椎间融合器和椎弓根螺钉内固定进行的TLIF技术似乎能够恢复峡部裂型腰椎滑脱患者的椎间隙高度并减少椎体向前移位，但矢状面排列的改善取决于椎间装置的靠前放置。
