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...

The vertebral column is situated in the median line, as the posterior part of the trunk. It (backbone) consists of a series of 26 individual irregular bones called vertebrae, separated by fibrocartilaginous intervertebral discs and are secured to each other by interlocking processes and binding ligaments. There are 7 cervical, 12 thoracic, 5 lumbar, 5 fused sacral, and 4-5 fused coccygeal verte...

Vertebrae tracking in lumbar spinal video-fluoroscopy is the first step in the analysis of vertebrae kinematic in patients with lower back pain. This paper presents a technique to track the vertebrae using particle filters with image gradient based likelihood measurement. In the first X-ray frame, the vertebrae are semi-automatically segmented and a bi-spline curve is fitted to the landmark poi...

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 ...
