Patients with lumbosacral transitional vertebra (LSTV) have a significantly smaller sacral tilt (ST) angle, indicating a more vertical sacrum. This finding is consistent across LSTV types.
Area of Science:
- Radiology
- Orthopedic Surgery
- Anatomy
Background:
- Lumbosacral transitional vertebra (LSTV) is a common congenital anomaly.
- Limited data exists on the impact of LSTV on sacral tilt (ST).
Purpose of the Study:
- To compare sacral tilt (ST) angles in patients with and without lumbosacral transitional vertebra (LSTV).
Main Methods:
- Retrospective case-control study analyzing lumbar radiographs.
- Identified patients with Castellvi types II, III, and IV LSTV.
- Measured sacral tilt (ST) angle on lateral radiographs and compared with controls.
Main Results:
- 6.1% of 1588 radiographs showed LSTV (Castellvi types II, III, IV).
- Patients with LSTV exhibited a significantly smaller sacral tilt (ST) angle (p<0.001).
- No significant difference in ST angle was observed among LSTV types.
Conclusions:
- Lumbosacral transitional vertebra (LSTV) is associated with a reduced sacral tilt (ST) angle.
- Patients with LSTV present with a more vertically oriented sacrum compared to controls.

Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form...
