Partial Lumbosacral Transitional Vertebra: A case of unilateral sacralization and its embryological and clinical implications
Bolla SR
Abstract: 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.
