What is lumbar transitional syndrome?
Lumbosacral transitional vertebra is an anatomical variation of the fifth lumbar vertebra in which an enlarged transverse process can form a joint or fusion with the sacrum or ilium. The association of that variant with low back pain and the change in the biomechanical properties of the lumbar spine is called Bertolotti’s syndrome.
What is transitional lumbar?
Lumbosacral transitional vertebrae (LSTV) are congenital spinal anomalies, in which an elongated transverse process of the last lumbar vertebra fuses with varying degree to the “first” sacral segment. Likewise, people ask, what is a transitional vertebrae in human?
What is a transitional lumbar vertebrae?
“Transitional vertebra” is a fairly common spinal deformity, in which the lowest vertebrae of the spine, the fifth lumbar vertebra, is partially fused to the top of sacrum. This odd hybrid bone is not a proper lumbar vertebra, and certainly not a sacral segment either — thus, it is a “transitional” vertebra.
What does partial lumbarization of S1 mean?
Lumbarization of S1 or lumbarization of first sacral vertebra is a condition in which the first sacral vertebra is not completely attached to its fused sacral components but instead this first sacral vertebra appears like the other lumbar vertebrae. It is also called as an extra vertebra, additional lumbar vertebra or transitional vertebra.

What is a lumbosacral transitional vertebrae?
Lumbosacral transitional vertebrae (LSTV) are increasingly recognized as a common anatomical variant associated with altered patterns of degenerative spine changes. This review will focus on the clinical significance of LSTV, disruptions in normal spine biomechanics, imaging techniques, diagnosis, and treatment.
What is LSTV in spine?
LSTV are associated with alterations in biomechanics and anatomy of spinal and paraspinal structures, which have important implications on surgical approaches and techniques. LSTV are often inaccurately detected and classified on standard AP radiographs and MRI. The use of whole-spine images as well as geometric relationships between the sacrum and lumbar vertebra increase accuracy. Uncertainty regarding the cause, clinical significance, and treatment of LSTV persists. Some authors suggest an association between LSTV types II and IV and low back pain. Pseudoarticulation between the transverse process and the sacrum creates a “false joint” susceptible to arthritic changes and osteophyte formation potentially leading to nerve root entrapment.
What is the association between LSTV and morphological alterations of neural arch elements and auricular surfaces?
The association between LSTV with morphological alterations of neural arch elements and auricular surfaces is well established. Considering the biomechanical importance of these morphological alterations in maintaining stability of the lumbar spine, Mahato suggests re-defining and modifying the current classification of LSTV. Including facet and auricular surface status would allow clinicians to clearly delineate the entire range of information required to visualize and clinically interpret any subtype of LSTV affliction (Table 1).2
What is the weak iliolumbar ligament?
The weak iliolumbar ligaments result in vertebral segment instability and could subsequently lead to early disc degeneration. The formation of an articulation or boney union between vertebra and sacrum through the transverse process may represent an adaptive mechanism to compensate for a weak iliolumbar ligament and to preserve stability.20

Why is the lumbosacral junction important?
Their importance stems both because the altered anatomy can be symptomatic (e.g. cervical rib causing thoracic outlet syndrome) or because they can lead to confusion when describing findings and thus lead to an incorrect level operation.
What is a lumbosacral transitional vertebrae?
BACKGROUND CONTEXT: Lumbosacral transitional vertebrae (LSTVs) are a congenital vertebral anomaly of the L5-S1 junction in the spine. This alteration may contribute to incorrect identification of a vertebral segment, leading to wrong-level spine surgery and poor correlation with clinical symptoms. Although several studies describe the occurrence of this anomaly in back pain populations, investigation of the prevalence in the American general population is lacking.
