Case 11- Non-specific LBP

35 yo/female patient presents with non-specific LBP. This is a continuation of our prior case.

No prior trauma,  surgeries,  carcinoma, or corticosteroid regimen.



AP VIEW LUMBAR APINE. At the lumbosacral junction, a LSTV (lumbar transitional VB) is present with a large spatulated TVP on the right with pseudoarthrosis and associated degenerative change.


XRAY FINDINGS Seen above, the orginal Castellvi classification system derived in 1984.

transitional vertebrae

Lumbosacral Transitional Vertebrae: Classification, Imaging Findings, and Clinical Relevance Konin AJNR 31 Nov-Dec 2010 Konin, et al therorized in 2010 that  certain LSTV may be responsilbe for associated lower back discomfort, disc lesions, ipsilateral & contrateral facet pain & in the worst clinical scenario wrong level spinal surgery. (1)


LSTV types II and IV positively correlate with the prevalence
and severity of LBP and buttock pain according to Lorenzo Nardo, MD et al. 2012. (2)
Lumbosacral vertebrae of Castellvi types II, III, and IV are associated with greater lumbar degeneration according to MD et al. Department of Diagnostic Radiology, Oulu University Hospital, Oulu, Finland. (3)
