The purpose of this study was to examine the preventive effect of exercise on lumbar vertebrae in ovariectomized rats. Three-month-old female Wistar rats were divided into 3 groups: control group (A, n = 10); non-exercised ovariectomized group (B, n = 7) and exercised ovariectomized group (C, n = 7). The rats from group C were subjected to treadmill exercise (15 m/minute in the initial six week...

Autosomal dominant sacral agenesis is characterised by a partial agenesis of the sacrum typically involving sacral vertebrae S2-S5 only. Associated features include anorectal malformation, a presacral mass, and urogenital malformation. Together, these features have been defined as the Currarino syndrome. Recently, HLXB9 has been identified as the major causative gene in Currarino syndrome allow...

Background: The objective of this anatomical study was to perform the morphometry dried lumbar vertebrae in human cadavers. Methods: This utilized 200 adult cadaveric vertebrae. digital Vernier calipers used measurements. height, antero-posterior length, transverse length body vertebrae, interpedicular distance at lateral ends, lamina height and thickness, superior inferio...

This paper presents three-dimensional static modeling of the human lumbar spine to be used in the formation of anatomically-correct movement patterns for a fully cable-actuated robotic lumbar spine which can mimic in vivo human lumbar spine movements to provide better hands-on training for medical students. The mathematical model incorporates five lumbar vertebrae between the first lumbar verte...

Bone mineral density of the lumbar vertebrae (L2-4BMD) in involutional osteoporosis was measured by dual photon absorptiometry to investigate its relationship with the incidence of osteoporotic vertebral fractures of the thoracic and lumbar spine. In addition to monitor L2-4BMD, the author also examined the progress of vertebral fractures during drug treatments by means of radiographs. L2-4BMD ...

Context : The sacrum generally is composed of five vertebrae fused to form a triangular bony mass with four pairs of sacral foramina. The sacrum may contain six vertebrae, by development of an additional sacral element or by incorporation of the fifth lumbar or first coccygeal vertebrae produces five pairs of sacral foramina. Sacralization is entirely undiagnosable without an X-ray examination ...
