The direct lateral interbody fusion (DLIF), a minimally invasive lateral approach for placement of an interbody fusion device, does not require nerve root retraction or any contact with the great vessels and can lead to short operative times with little blood loss. Due to anatomical restrictions, this procedure has not been used at the lumbosacral (L5-S1) junction. Lumbosacral transitional vertebrae (LSTV), a structural anomaly of the lumbosacral spine associated with low back pain, can result in a level being wrongly identified pre-operatively due to misnumbering of the vertebral levels. To our knowledge, use of the DLIF graft in this patient is the first report of an interbody fusion graft being placed at the disc space between the LSTV and S1 via the transpsoas route. We present a review of the literature regarding the LSTV variation as well as the lateral placement of interbody fusion grafts at the lumbosacral junction.
直接侧方椎间融合术（DLIF）是一种微创的侧方入路，用于放置椎间融合器，不需要神经根牵拉，也不需要与大血管接触，手术时间短，出血量少。由于解剖学限制，该手术未应用于腰骶部（L5-S1）交界处。腰骶移行椎（LSTV）是腰骶部脊柱的一种结构异常，与腰痛有关，由于椎体编号错误，术前可能会错误地确定一个节段。据我们所知，在这位患者中使用 DLIF 移植物是首例通过经椎间孔途径将椎间融合移植物放置在 LSTV 和 S1 之间的椎间盘间隙的报告。我们回顾了有关 LSTV 变异以及腰骶部椎间融合移植物侧方放置的文献。
