Introduction Osteoid osteoma (OO) is a benign lesion accounting for approximately 12% of benign skeletal neoplasms [1]. OO maybe in different localizations involving mainly long bones of the extremities and posterior elements of the vertebrae, mostly at the thoracic and lumbar region. Localization in the vertebral body is unusual [2]. In this article a case of OO localized in the thoracic verte...

In this review, we explored the progress of the pathogenesis of Kümmell's disease intravertebral vacuum. Using different expressions of the same disease including 'Kümmell's disease', 'avascular necrosis after vertebral compression fracture (VCF)', 'post-traumatic vertebral osteonecrosis', 'vertebral pseudarthrosis', 'intravertebral vacuum (cleft or gas)', 'delayed vertebral collapse', 'VCF non...

The degree of vertebral wedging, a key structural characteristic of spinal curvatures, has recently been found to be negatively related to vertebral cross-sectional area (CSA). The purpose of this longitudinal study was to examine the relation between vertebral cross-sectional growth and vertebral wedging progression within the immature lumbar spine. Using magnetic resonance imaging (MRI), we a...

BACKGROUND AND PURPOSE The prevalence of facet joint signal change in acute/subacute lumbar vertebral body compression fractures is unknown. We hypothesized that facet joint signal change on MR imaging is more common in facet joints associated with an acute/subacute lumbar compression fracture than those associated with normal vertebral bodies or ones that have a chronic compression fracture. ...

To determine the effectiveness of the application of one stage posterior approach osteotomy with screw rod fixation and cage inserting anteriorly in late kyphosis deformity. 39 cases of late kyphosis deformity treated with one stage posterior approach osteotomy with screw rod fixation and cage inserting anteriorly were retrospective reviewed. The height of anterior and posterior margin of verte...

STUDY DESIGN Retrospective study. PURPOSE This study was conducted to compare vertebral body height restoration rate in rheumatoid arthritis (RA) patients who had undergone percutaneous balloon kyphoplasty (KP) with that of control group who had matched age, sex, body mass index, and bone mineral density. OVERVIEW OF LITERATURE There is no report on result of KP in RA patients. METHODS Po...

We report the serial MR imaging and neuropathologic findings in a patient with fibrocartilaginous embolism to the spinal cord, presumptively originating from vertebral body endplates. Extensive increased T2 signal intensity, minimal contrast enhancing foci, concomitant vertebral body bone marrow infarction, and terminal cord hemorrhagic necrosis were the main MR imaging features. Pathologic exa...

In order to provide effective options for minimally invasive treatment of spinal metastases, the present study retrospectively evaluated the efficacy and safety of image-guided minimally invasive percutaneous treatment of spinal metastases. Image-guided percutaneous vertebral body enhancement, radiofrequency ablation (RFA) and tumor debulking combined with other methods to strengthen the verteb...

The registration of cross-sectional medical images with patient anatomy is an important problem in image-guided surgery. Current registration methods such as paired-point matching can be tedious and require large incisions. Improved methods of registration for percutaneous spine procedures could potentially improve the accuracy of minimally invasive spine procedures. In this poster, we will des...
