METHODS: We attempted endoscopically assisted screw fixation in a patient with degenerative spondylolisthesis. Through a third portal, ipsilateral CBT screws were implanted without complications.
CONCLUSIONS: We successfully performed unilateral biportal endoscopic lumbar interbody fusion (ULIF) with CBT and reversed CBT screws. Compared with percutaneous pedicle screw (PPS) placement, this procedure is a minimally invasive, endoscopic alternative that allows precise screw placement.
方法:我们尝试对1例退行性腰椎滑脱患者进行内窥镜辅助螺钉内固定。通过第三个门户,同侧CBT螺钉植入无并发症。
结论:我们成功地进行了单侧双门镜下腰椎椎间融合术(ULIF)与CBT和反向CBT螺钉。与经皮椎弓根螺钉(PPS)置入相比,这个手术是微创的,内窥镜替代,允许精确的螺钉放置。
