Abstract

Normally, 5 human lumbar vertebrae exist. However, approximately, 4-21% of the general population and 10% of adults seen with symptomatic degenerative conditions of the low back have a lumbosacral transitional vertebra (LSTV). These anomalies are mainly failures of symmetrical or asymmetrical segmentation. In these cases, the last lumbar vertebra contains an elongated of its transverse process, with varying degrees of fusion to the “first” sacral segment. The term LSTV is now recommended over “sacralized L5” or a “lumbarized S1”. No standard method is established for vertebral numbering based solely on sagittal lumbar magnetic resonance images (MRIs). The iliolumbar ligament (ILL) is readily identifiable on axial L-spine MRI and always arises from the L5 vertebra (based on anatomic and MRI studies)[21]. Therefore, by identifying L5, physicians can increases their confidence of correctly assigning lumbar levels.
