The aim of this study was to increase the awareness of TLTV and LSTV to reduce wrong-site surgery or diagnostic errors. Detailed knowledge of these transitional vertebrae may potentially benefit spine surgeons as well as radiologists and interventional pain medicine specialists.
Others
The presence of transitional vertebra in the thoracolumbar and/or lumbosacral regions may cause wrong-site surgery and problems while measuring spinopelvic parameters, including pelvic incidence and lumbar lordosis. The Castellvi classification of lumbosacral transitional vertebra (LSTV) addresses coronal images but not sagittal or axial images. Therefore, it is unclear how LSTV differs from the normal lumbosacral anatomy. We aimed to investigate the lumbosacral anatomy and vertebral numbering in patients with thoracolumbar transitional vertebrae (TLTV) and/or LSTV by performing computed tomography (CT) to identify TLTVs, to number presacral vertebrae accurately and to analyze morphological differences in each LSTV type.
Each LSTV type was examined to identify its morphological features on sagittal and axial CT images.

LSTVs were observed in 111/880 patients (12.6%). Castellvi type III LSTVs were the most common (42/111, 37.8%), followed by S6 LSTVs (37/111, 33.3%). TLTVs were associated with LSTVs (87/111, 78.4%) and commonly identified at T13 (59/87, 67.8%).

Degenerative lumbar diseases who underwent thoracolumbar fusion.
The medical records of 880 patients who underwent thoracolumbar fusion between July 2014 and March 2020 were evaluated for TLTV and LSTV. In this study, 124 (14.1%) of 880 patients had transitional vertebrae and/or vertebral numeric variation, with a mean age (and standard deviation) of 69.7 (12.0) years and male patients accounting for 60.5% of these 124 patients.
None
The anatomical location of the lowest thoracic vertebra was defined, and TLTV with dysplastic ribs was identified and classified. Each LSTV type was examined for its morphological features on sagittal and axial CT images.
