The spinal column is the central structure in the vertebrate body from which stability, movement, and posture all derive. The vertebrae of the spine are organized into four regions (listed in order from cranial to caudal): cervical, thoracic, lumbar, and pelvic. These regions are classified by their differences in curvature. The human spine usually consists of thirtythree vertebrae, seven of wh...

There is no agreement in the literature as to the time of the onset and progress of the vertebral column ossification. The aim of the present study was to determine the precise sequence of ossification of the neural arches and vertebral centra.Histological and radiographic studies were performed on 27 human foetuses aged from 9 to 21 weeks. It was found that the ossification of vertebrae commen...

A method has been developed for the objective assessment of vertebral 'squaring' based on quantitative morphometric analysis of vertebral 'concavity' in lateral radiographs of the lumbar spine. The reference range for vertebral concavity was defined as greater than 1.0-4.0 mm from measurements of 255 radiologically normal lumbar vertebrae in 51 patients with non-specific back pain. Evidence of ...

The aim of this study was to investigate features of abdominal earthquake-related crush traumas in comparison with non-earthquake injury. A cross sectional survey was conducted with 51 survivors with abdominal crush injury in the 2008 Sichuan earthquake, and 41 with abdominal non-earthquake injury, undergoing non-enhanced computed tomography (CT) scans, serving as earthquake trauma and control ...

It is the purpose of this work to investigate whether it is feasible to develop Finite Element (FE) models that take into account the geometric differences between the lumbar vertebrae of patients. It is also the purpose of this work to determine whether or not such patient specific differences affect the results of the FE analysis in such a significant way that they should be considered in fut...

Abstract Numerous studies are based on the use of animal models; however, in bipedal and tetrapedal organisms there significant differences biomechanics spinal column, which can significantly impair quality applicability results obtained. The aim this study is to obtain basic data morphometric parameters guinea pig lumbar vertebrae, analysis will indicate location biggest mechanical load. verte...

The Anatomy of the Lumbar Vertebral Column T he lumbar portion of the vertebral column has an ideal structure aiming at maintaining stability and mobility. This region has a solid structure designed to carry the weights of the head, the neck, the trunk and the extremities. The pains associated with this region are very common complaints affecting 80% of the population at least one time during t...

A detailed lumbar spine FE component model (including vertebrae, inter-vertebral discs, all ligaments and facet joints of T12-L5) was built per the Global Human Body Model Consortium (GHBMC) CAD data. The lumbar model was correlated with the Post-Mortem Human Subject (PMHS) lumbar spine tests under flexion, compression and anterior shear loading modes in the physiological ranges (Belwadi, 2008)...
