Lumbosacral transitional vertebrae (LSTV) are congenital anomalies of the lumbosacral spine. In lumbosacral transitional vertebrae either sacralization of the lowest lumbar segment or lumbarization of the upper sacral segment of the spine is seen. One of the sacra from macerated cadavers has shown sacralization with unilateral fusion of transverse process on right side, while on left side it was normal, there was no fusion of bodies and left transverse processes of lumbosacral transitional vertebrae and first sacral vertebrae. Since there is association between lumbosacral transitional vertebrae and low back pain (LBP) and other spinal pathology; this anomaly has increased clinical interest. The morphological details of the case, its embryological and clinical implications from the literature are reviewed.
腰骶部移行椎（LSTV）是腰骶椎的先天性异常。在腰骶部移行椎中，可见最低腰椎节段的骶化或脊柱上骶段的腰化。一具经浸软尸体的骶骨之一显示右侧横突单侧融合的骶化，而左侧正常，腰骶部移行椎与第一骶椎的椎体和左侧横突无融合。由于腰骶部移行椎与腰痛（LBP）及其他脊柱病理情况之间存在关联，这种异常增加了临床关注。本文回顾了该病例的形态学细节、其胚胎学及文献中的临床意义。
