13. Protocolo de fotogrametria computadorizada na quantificacao angular da escoliose
The scoliosis is a three-dimensional deformation of the spine. It is a serious disease that can compromise vital organs like heart and lungs, in addition to influence the aesthetic and quality of life. His progression is generally associated with growth peak, getting in that case, the name of the adolescent idiopathic scoliosis (AIS). Thus, the pubertal peri

14. Análise fotoelástica de modelo de vértebra sob influência de parafuso pedicular / Photoelastic analysis of a vertebra model under the pedicular screw influence
O sistema de fixação vertebral utilizando o parafuso pedicular é um dos métodos mais eficientes no tratamento de patologias da coluna vertebral. Quando o parafuso estiver submetido à força de arrancamento, ele gera tensões ao redor, principalmente próximo do canal medular, situação que pode ser analisada pela técnica da fotoelasticidade. O objetiv

15. Resultados da vertebroplastia percutânea na doença vertebral cervical / Results of percutaneous vertebroplasty in the cervical spine
A vertebroplastia percutânea (VP) consiste na injeção de polimetilmetacrilato (PMMA) no corpo vertebral para alívio da dor e estabilização vertebral, porém seu uso na região cervical é restrito. No intuito de avaliar a efetividade e a segurança da VP na região cervical (VPC), foram avaliados 75 pacientes que se submeteram à VPC (n=101) por doenç

16. Ontogenia dos ossos do esqueleto da tartaruga-da-amazÃnia Podocnemis expansa Schweigger, 1812 (Testudines, Podocnemididae) / Bone ontogeny of the cranium of the giant amazon river turtle podocnemis expansa schweigger, 1812 (testudines, podocnemididae)
CHAPTER 2: The freshwater turtle Podocnemis expansa is found all over the Amazon basin and appears in almost all of its tributaries. The vertebrate skeleton is composed of cartilage and bone and represents the cell product of three different embryonic lineages. The cranium is formed by cells of the neural crest. Knowledge of the biological criterion for the

17. Comparação da prevalência das anomalias de vértebras cervicais superiores em pacientes com fissura de lábio e/ou palato e pacientes sem fissura / Prevalence comparison of upper cervical vertebral anomalies in patients with cleft lip and/or palate and noncleft patients
One of the possible mechanisms for cleft palate development is represented by the congenital anomalies of the vertebral spine. Correlation of cleft different types with associated anomalies may enhance the understanding on the embryonic phenomena and processes of malformation The studies have observed a relationship between cleft palate and vertebral anomali

18. Evaluation of vertebral bodies and intervertebral discs participation in the lumbar lordosis / Avaliação da participação dos corpos vertebrais e discos intervertebrais na composição da lordose lombar
The vertebral bodies and intervertebral discs participation in lumbar lordosis and their contribution between lumbar curves of different size were studied. 350 lumbar spine radiographs of asymptomatic adults (143 men and 207 women, average age 29 years) were evaluated. Lumbosacral (L1S1) and lumbolumbar (L1L5) curves and the angular inclination of each verte

21. A radiographic study of the human fetal spine. 3. Longitudinal growth.
Regression equations are presented which describe the growth in length of the various regions of the vertebral column in the human fetus. From 8 weeks on the thoracic is always the longest region and the sacral the shortest, while the lumbar region is longer than the cervical. From the regression equations predictions of fetal vertebral length can be made fr

22. Intraosseous neurilemmoma of the cervical spine causing paraparesis and treated by resection and grafting.
A neurilemmoma presented as an expanding lesion of the bodies of C6 and C7 vertebrae and caused local neurological signs together with a spastic paraparesis. This tumour was treated by preliminary posterior fusion, followed by its complete removal via an anterior approach and stabilization by anterior spinal fusion. Other cases in the literature are reviewed

23. Molecular and Phenotypic Characterization of a New Mouse Insertional Mutation That Causes a Defect in the Distal Vertebrae of the Spine
We have identified and characterized the phenotype of a new insertional mutation in one line of transgenic mice. Mice carrying this mutation, which we have designated TgN(Imusd)370Rpw, display undulations of the vertebrae giving rise to a novel kinky-tail phenotype. Molecular characterization of the insertion site indicates that the transgene integration has

24. A new method for the radiological assessment of vertebral squaring in ankylosing spondylitis.
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
