The orientation of the superior articular processes in thoracic and lumbar vertebrae differs. The present study was undertaken to investigate the possible mechanism for the change from a posterolaterally facing superior articular surface in the thoracic region to a posteromedially facing curved articular surface in the lumbar region. The material of the study consisted of dry macerated bones of...

IS-Tlk/Kyo, a mutant derived from IS/Kyo strain, exhibits a kinked and/or short tail, in addition to the congenital lumbar vertebral anomaly. Homozygotes of Tlk dominant gene are known to die during embryonic development. We previously reported the morphological features of the skeleton in IS/Kyo and IS-Tlk/Kyo fetuses and of the heart in IS/Kyo fetuses [19]. This study was conducted to clarify...

caudal regression syndrome (caudal dysplasia sequence) is a rare congenital malformation. it has a spectrum ranging from simple anal atresia to the absence of sacral, lumbar and possibly lower thoracic vertebrae and the most severe form called sirenomelia (mermaid syndrome). sirenomelia has a sole characteristic, which is the limbs fusion, with multiple internal structural abnormalities particu...

Introduction: Diffuse Idiopathic Skeletal Hyperostosis (DISH) is a very rare cause of dysphagia when it occurs in the cervical spine. It can also affect the lumbar region where it causes deformity. Case Report: In this article, a rare case of Diffuse Idiopathic Skeletal Hyperostosis involving both the cervical and lumbar spine, presenting with dysphagia and spinal stiffness leading to a stoopin...

Background: Variations in the number of ribs and vertebrae have been noted in other wise normal looking people with some having supernumerary while others subnumerary. Sternal variations and anomalies though have not been as widely documented. These are two cases with one having a combination of sternal anomalies, supernumerary thoracic vertebrae and ribs and subnumerary lumbar vertebrae while ...

A rare case of recurrent meningitis due to congenital anterior sacral meningocele and agenesis of the sacral and coccygeal vertebrae is described. An autosomal dominant inheritance is demonstrated for lower cord malformation, and environmental factors (chromic acid or fumes) are discussed.

Radiologist always examines X-ray to determine abnormal changes in cervical, lumbar & thoracic vertebrae. Osteophyte (bony growth) may appear at the corners of vertebrae so that vertebral shape becomes abnormal. This paper presents the idea from Image processing techniques such as customised Hough transform which will be used for segmentation which should be independent of rotation, scale, nois...

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...

Incidental detection of lumbar Paget's disease by bone densitometry SIR, Bone densitometry of the hip and lumbar spine using dual-energy X-ray absorptiometry (DXA) is used to diagnose osteoporosis. We report three patients who were referred for bone densitometry, in whom a diagnosis of Paget's disease was made after the investigation of significantly increased bone mineral density (BMD) of a si...

Direct measurements were made on 2,166 lumbar vertebrae of 433 adult negro and caucasoid skeletons. On statistical analysis, forty-five vertebrae in twenty-seven skeletons were found to be stenotic, the mid-sagittal diameter being the significantly reduced dimension. Whereas spinal stenosis syndromes are rare in South African negroes, the lumbar canal is marginally narrower in the negro. There ...
