Lumbosacral Transitional Vertebrae Cause Spinal Level Misconception in Surgeries for Degenerative Lumbar Spine Disorders

The association between lumbar rib and lumbosacral transitional vertebrae

Lumbosacral transitional vertebrae and nerve-root symptoms.

Transitional vertebrae (TV) may be one of the risk factors for lumbar disc herniation. It is not clear, however, whether the presence of TV can affect the development of nerve-root symptoms. Our aim was to clarify this relationship. A total of 501 patients with lumbar degenerative disease and nerve-root symptoms was studied in respect of their level and the presence of TV. As a control group, 5...

Are Spinal or Paraspinal Anatomic Markers Helpful for Vertebral Numbering and Diagnosing Lumbosacral Transitional Vertebrae?

OBJECTIVE To evaluate the value of spinal and paraspinal anatomic markers in both the diagnosis of lumbosacral transitional vertebrae (LSTVs) and identification of vertebral levels on lumbar MRI. MATERIALS AND METHODS Lumbar MRI from 1049 adult patients were studied. By comparing with the whole-spine localizer, the diagnostic errors in numbering vertebral segments on lumbar MRI were evaluated...

Lumbosacral transitional vertebrae: incidence in a consecutive patient series.

BACKGROUND Great variability exists in the reported frequency of transitional vertebra in the general population as well as in symptomatic lumbar spine patients. OBJECTIVE To determine the occurrence rate of transitional vertebra in consecutive lumbar spine patients in our practice. DESIGN A prospective, observational study METHODS Plain films were viewed and the presence or absence of a ...

Incidence of numerical variants and transitional lumbosacral vertebrae on whole-spine MRI

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,...
