background: spine of an adult is made up of five areas that include 7 cervical vertebrae, 12 thoracic vertebrae, 5 lumbar vertebrae, sacrum and finally coccyx. selecting appropriate assumptions for modeling and biological analysis of the spine components has a significant impact on the accuracy of results in biomechanical simulation for different modes. methods: in the present study, biomechani...

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,...

The German Shepherd is among the breeds most prone to pathologies of lumbosacral spine. aim study was examine how presence spine pathology affects shape lumbar and dimensions individual vertebrae. Mathematical analysis consisted three measurements for each vertebra. Based on analysis, it concluded that there a correlation between height first five vertebrae occurrence transitional vertebra (LTV...

purpose many factors such as lumbar instability and spinopelvic alignment are associated with low back pain. our purpose was to analyze the pelvic incidence - one of spinopelvic alignment parameters- and spine instability correlations in patients with chronic low back pain. methods fifty-two patients suffering from chronic low back pain entered this case control study. lateral spine radiography...

introduction: cauda equina secondary to metastatic follicular thyroid cancer of the lumbosacral area is a rare entity.   case report: we report an unusual case of a 52-year-old male who presented with backache, lower limb weakness, and perianal numbness. a ct-scan of the lumbosacral area showed an enhancing mass at the l4, l5 and s1 vertebrae. histopathology after excision revealed a metastatic...

Vertebral fractures commonly occur at the thoracolumbar junction. These fractures can be treated with mild residual deformity in many cases, but are reportedly associated with increased risk of secondary vertebral fractures. In the present study, a three-dimensional (3D) whole spine model was constructed using the finite element method to explore the mechanism of development of compression frac...

Radiologists are often plagued by limited time for completing their work, with an ever increasing workload [31]. A picture archiving and communication system (PACS) is a platform for daily image reviewing that improves their work environment, and on that platform for example spinal MR images can be reviewed. When reviewing spinal images a radiologist wants vertebrae labels, and in Sectra’s PACS...

In this paper we will describe our experiments with x-ray image analysis for vertebra detection in juvenile/adolescent patients with idiopathic scoliotic spines. We will focus on detecting vertebrae location in a anterior-posterior x-ray image in a fully automatic way. For accomplishing this, we propose a set of techniques for (i) isolating the spine by removing other bone structures (e.g. ribs...

background: cervical spine sustains most of thevertebral column injuries, among other injuries, the disc degeneration and damage that lead to replacement of the damaged disc with cage or artificial disc. methods: the c4 to c6 vertebrae of a normal subject and a person with interbody fusion cage were 3d modelled and then analyzed using finite element method. the results of maximum stress and str...

The lumbosacral region of the spine is most susceptible to pathology in large breed dogs. common pathologies this segment include intervertebral disk discopathy, distortion vertebral vertebrae, narrowing canal and congenital defects spine. This area commonly affected by physical trauma or aging-related conditions leading a wide range symptoms, such as pain loss mobility.
