Musculoskeletal modeling is a well-established method in spine biomechanics and generally employed for investigations concerning both the healthy pathological spine. It commonly involves inverse kinematics optimization of muscle activity provides detailed insight into joint loading. The aim present work was to develop validate procedure automatized generation semi-subject-specific multi-rigid b...

conclusions managing such patients needs a proper transport facility, proper care during transport, appropriate evaluation in the hospital and prompt conservative or operative treatment. treatment is usually safe and effective by well trained professionals with good clinical and radiological outcomes. patients and methods thirty patients (22 males, 8 females) with upper cervical spine injuries ...

introduction: to examine the hypothesis that diffusion weighted imaging (dwi) in lumbosacral region could reveal sciatic nerve course swelling that lead to lower extremity pain. the aim of present article was to find and evaluate the diffusion weighted coefficients (b-values) for scrutinizing sciatic nerve tract changes in lumbosacral region. materials and methods: lumbar area was imaged in 30 ...

background metastatic spinal tumors are common and major causes of pathological spinal fractures that result in severe pain, weakness, and progressive neurological deficits. this study aims to evaluate the efficacy of percutaneous vertebroplasty (pvp) in pain-relief in patients with spinal fractures due to metastatic spinal tumors. methods we evaluated 25 documented cases of metastatic spinal t...

abstract   backgrounds: pott's disease is a rare form of extrapulmonary tuberculosis, and   presents with several clinical patterns. delay in diagnosis and management may   cause serious complications. we conducted a retrospective study between 1991-   2006 to evaluate clinical presentation, radiologic and laboratory findings, and therapeutic   approaches to spinal tuberculosis.   methods:...

The vertebral column is built from alternating bony vertebrae, interconnected with fibrocartilagenous discs and diarthrodial facet joints. In total 33 vertebrae (7 cervical, 12 thoracic, 5 lumbar, 5 sacral and 4 coccygeal) all conform to a basic plan. With the exception of the atlas and axis, all vertebra are made of an anterior approximately cylindrical vertebral body and an arch composed of p...

The facet joint is a crucial anatomic region of the spine owing to its biomechanical role in facilitating articulation of the vertebrae of the spinal column. It is a diarthrodial joint with opposing articular cartilage surfaces that provide a low friction environment and a ligamentous capsule that encloses the joint space. Together with the disc, the bilateral facet joints transfer loads and gu...

background: we aimed to define and compare the risk factors of spinal and femoral osteoporosis in postmenopausal iranian women. method: it was a multicentre based study carried out in two stages during 2002 to 2005 among post menopausal women in tehran. in first stage case group included 140 women with diagnosed spinal osteoporosis using dexa method as definition of who and controls were 167 wo...
