OBJECTIVES To test whether the position of lumbosacral dermatomes varies in the presence of transitional vertebrae. MATERIAL AND METHODS Fifty consecutive male patients were tested for thoracolumbar and lumbosacral transitional vertebrae by radiography and for the position of the dermatome gap between the lumbar dermatomes L1, L2, L3, and the sacral dermatomes S2 and S3. The dermatome gap was...

Transforaminal lumbar interbody fusion (TLIF) is commonly used procedure for spinal fusion. However, there are no reports describing anterior cage dislodgement after surgery. This report is a rare case of anterior dislodgement of fusion cage after TLIF for the treatment of isthmic spondylolisthesis with lumbosacral transitional vertebra (LSTV). A 51-year-old man underwent TLIF at L4-5 with post...

Study Design Descriptive cross-sectional study. Purpose To determine the frequency of lumbosacral transitional vertebrae (LSTV) in patients with low back pain (LBP) and the role of iliolumbar ligament (ILL) origin from L5 in LSTV cases. Overview of Literature Transitional vertebrae are developmental variants of the spine. LSTV is a common congenital abnormality, and failure to recognize thi...

OBJECTIVES This study sets out to prospectively investigate the incidence of transitional vertebrae and numerical variants of the spine. MATERIALS AND METHODS Over a period of 28 months, MRIs of the whole spine were prospectively evaluated for the presence of transitional lumbosacral vertebrae and numerical variants of the spine. RESULTS MRI of the whole spine was evaluated in 420 patients,...

OBJECTIVE Lumbosacral transitional vertebra (LSTV) and spina bifida occulta (SBO) are widespread within the lumbosacral spine. Their connection to lumbar disc herniation (LDH) and/or lower back pain has been debated in the current literature; however, there is no consensus. The purpose of this study is to evaluate the relationship between the frequency of LSTV and SBO with that of LDH among you...
