The spinal cord in adults may terminate between the last thoracic and the third lumbar vertebra
, but in most cases, it ends at the first or second lumbar vertebra
The bone material density of the lumbar vertebra
, tibial neck and Ward's triangle of every research subject was measured using dual-energy x-rays absorptiometry (GE, USA).
Lumbosacral transitional vertebra is an anatomical variation of the fifth lumbar vertebra
. Transverse process becomes enlarged and forms a joint or fusion with the sacrum or ilium.
The Cohen's Kappa statistical study revealed a general index of 0.92 for the location of the thoracic apical vertebra and 0.825 for the location of the lumbar vertebra
. With a significance level of 5% the null hypothesis is rejected, which shows that the agreement between the two tests is different from zero; that is, they are concordant.

A lumbar vertebra
associated with Individual 3 exhibited nonunion of the right pars interarticularis (Fig.
Meanwhile, we performed the CT-guided needle biopsy from the osteoblastic lesion of the second lumbar vertebra
, which was diagnosed with bone metastasis by CT and bone scintigraphy, to exclude vertebral bone metastasis of prostate cancer by an orthopedic unit of another hospital, which the patient visited owing to lumbago and bilateral lower limb paralysis.
The upper and lower bars are worn on the back over the first lumbar vertebra
and the fifth lumbar vertebra
with shoulder straps and a waist belt, as pictured in Figure 4.
Traumatic lumbosacral dislocation is a rare clinical entity, characterized by unilateral or bilateral facet dislocations causing displacement at the level of the fifth lumbar vertebra
in relation to the sacrum .
Stress Analysis of Osteoporotic Lumbar Vertebra
Using Finite Element Model with Microscaled Beam-Shell Trabecular-Cortical Structure, J Appl Math 2013(2013): 1-6.
Hence, it is of great value to report our case of monostotic Paget's disease involving the lumbar vertebra
that was effectively managed by conservative modalities.
The subjects lay in the prone position on a bed, and one surgeon helped to locate the landmarks of the spinous processes of the third and seventh thoracic vertebra (T3, T7), of the first, third, and fifth lumbar vertebra
(L1, L3, L5), left and right posterior superior iliac spine (LPSIS, RPSIS), and the iliac crest (IC).
