This paper presents a new 3D reconstruction method of the scoliotic vertebrae of a spine, using two conventional radiographic views (postero-anterior and lateral), and a global prior knowledge on the geometrical structure of each vertebra. This geometrical knowledge is efficiently captured by a statistical deformable template integrating a set of admissible deformations, expressed by the first ...

vertebra plana is a radiological diagnosis that indicates complete compression of the vertebral body.(1,2) this condition was reported in langerhans cell histiocytosis including eosino-philic granuloma,(3, 12) ewing's sarcoma,(2,13,14) tuberculosis,(15,16) vertebral osteomyelitis,(17) aseptic necrosis,(18) aneurysmal bone cyst,(19) osteosarcoma,(20) neuroblastoma,(21) acute leu-kemia,(22) rhabd...

Introduction: Atlas Vertebra (1st cervical vertebra) is called “atypical vertebra” and has unusual shape andarchitecture. The dimensions of atlas vertebra are most essential in the technique cranio-vertebral regionstabilization. Retroarticular canals foramina transversaria important for transoral transpalatinalapproaches to clivus, axis.Aim objectives: To study incidence symmetry transversaria....

Accurate spine segmentation allows for improved identification and quantitative characterization of abnormalities of the vertebra, such as vertebral fractures. However, in existing automated vertebra segmentation methods on computed tomography (CT) images, leakage into nearby bones such as ribs occurs due to the close proximity of these visibly intense structures in a 3D CT volume. To reduce th...

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...

OBJECTIVE To determine the position of the aortic bifurcation and the iliocava junction in relation to the lumbar vertebra, aortic bifurcation angle, interiliac angle, and anatomical variation of the iliac veins anterior to the lumbar vertebra of Thai people. MATERIAL AND METHOD The present study was done on 65 cadavers. The mean ages of the cadavers were 73 +/- 10 years (range from 50 to 90 ...

Spondylolysis is the term used for a defect in the pars interarticularis of the vertebra. The term is from the Greek roots spondylos, meaning vertebra, and lysis, meaning break or defect. Spondylolisthesis is from spondylos and listhesis, meaning movement or slipping, and refers to the slipping forward of one vertebra on the next caudal vertebra. Spondylolisthesis was first described in 1782 by...
