BACKGROUND Osteoporotic vertebral compression fracture is a serious complication of osteoporosis. Various vertebral kyphoplasty surgeries, which have their own unique features, are commonly used for osteoporotic vertebral compression fracture. Based on the anatomic property of the thoracolumbar vertebral pedicle that its horizontal diameter is twice that of the vertical diameter, we designed Ja...

STUDY DESIGN Retrospective observational study. PURPOSE To identify the role of percutaneous vertebral biopsy in histopathological diagnosis of vertebral compression fractures and to identify the frequency of unexpected malignancy in vertebral compression fractures. OVERVIEW OF LITERATURE Vertebral compression fractures are common in the Indian population. Magnetic resonance imaging and nuc...

BACKGROUND The V2 segment of the vertebral artery is very vulnerable to injury during cervical spine surgery. The incidence of vertebral artery injury during anterior cervical spine procedures is reported to be 0.22-2.77 %. This is partially due to its variable course while running in the transverse foramens of the cervical vertebrae. CASE PRESENTATION The course of the vertebral artery in th...

STUDY DESIGN The shape of the L5 vertebral body was analyzed using a computerized tomography (CT) scan. OBJECTIVE The aim of this study is to determine if the vertebral L5 body shape varies depending on the height of the CT slices through the L5 pedicle. SUMMARY OF BACKGROUND DATA The morphometry of L5 has been studied to help the introduction of pedicular screws. The shape of the vertebral...

Introduction: Vertebral collapse is associated with breakdown of vertebra resulting in decrease in height of vertebral body. Magnetic Resonance Imaging is well known method to evaluate bone and bone marrow diseases, one of the reliable markers to differentiate between benign and malignant compressive fractures and certain characteristics which aids in early differentiation of benign and maligna...

A registration method that identifies bone geometry with respect to a robotic manipulator arm is presented. Although the method is generally applicable to many orthopaedic internal fixation procedures, it was only demonstrated for the insertion of pedicle screws in vertebral bodies for spine fixation. The method relies upon obtaining an impression of the vertebral bodies. Computerized tomograph...

background: osteoporotic compression vertebral fractures are common clinical problems. in those with refractory fractures, percutaneous cement augmentation has been suggested. the aim of this study was to evaluate the functional outcome of percutaneous vertebroplasty in iranian patients with refractory osteoporotic fractures. methods: we retrospectively studied 37 osteoporotic fractures in 28 p...

Cervicogenic vertigo was known as Bow hunter's syndrome. Occlusion of vertebral artery causes vertebrobasilar insufficiency and we reported cervicogenic vertigo case which was treated by simple decompression of transverse foramen of C1. The patient was 48 years old female who had left side dominant vertebral artery and vertigo was provoked when she rotated her head to right side. Angiography sh...

Vertebral artery origin stenosis is a common occurrence among patients with ischemic events in the vertebral and basilar arterial distribution [1,2]. Of the 407 patients in the New England Medical Center Posterior Circulation Registry, 80 (20%) of patients with ischemic events in the vertebral and basilar arterial distribution had vertebral artery origin occlusion or high-grade stenosis [1]. Tr...

OBJECTIVE To investigate the relationship between MRI inflammation at the vertebral unit and the formation and growth of syndesmophytes at the same vertebral unit. METHODS An 80% random sample of the ASSERT database was analysed. MRI were scored using the ankylosing spondylitis (AS) spinal MRI activity score (at baseline, 24 and 102 weeks) and spinal x-rays were scored using the modified Stok...
