Distractible vertebral body replacement for the thoracic and lumbar spine.
We retrospectively evaluated the results after corporectomy and vertebral body replacement in 40 patients with thoracic or lumbar spine collapse due to tumour osteolysis, unstable fractures, spondylodiscitis and Paget's disease. They underwent posterior transpedicular instrumentation followed 7 to 21 days later by vertebral body replacement with a distractible device, the "Obelisc" cage, filled...
متن کاملMonostotic Vertebral Paget's Disease of the Lumbar Spine.
Paget's disease in the Far East is quite rare. Age at diagnosis is usually greater than 50 years, and the disease typically affects the spine. Most patients are usually diagnosed with Paget's disease following radiographic examination for other purposes. It usually occurs at multiple vertebral levels, with only 10-25% of vertebral Paget's disease being monostotic. The disease rarely causes neur...
متن کاملLumbar Spine Vertebral Motion Characters in Sagittal and Transverse Planes
Previous in-vivo studies have mostly used X-ray images to measure the vertebral rotational centers in sagittal plane. Recently, advanced medical image techniques such as CT, MRI and dual plane fluoroscopic have enabled investigation of 3D motions of the vertebral body in space. We have applied the combined dual fluoroscopic imaging system (DFIS) and MR imaging technique to investigate the 6DOF ...
متن کاملThe ossification of the vertebral column, thorax and sternum in the quail (Coturnix coturnix japonica)
The ossification centers onset of the quail vertebrae, ribs, and sternum in embryos and hatchling birds was studied. Specimens were cleared, stained with Alcian Blue and Alizarin Red S and examined using stereomicroscope. The chondral rudiments of the vertebrae were observed at the 6th day of incubation (E6). The osteogenesis of the vertebrae was accomplished with both perichondral a...
متن کاملPreliminary metrological study of the lumbar vertebral column during the foetal period.
The aim of our study was to elaborate a scheme for the development of the particular elements of the lumbar vertebral column in the foetal period based on metrological data analysis. 30 human foetuses between 31 and 183 mm C-R length were examined. The whole vertebral column and lumbar segment length, intervertebral spaces and structural elements of each vertebra were measured. Statistical anal...
