dissection of the vertebral artery is an important but rare cause of cerebrovascular accidents. here we report a 48-year-old man with toothache since 4 days before who presented to the emergency department with neck pain and final diagnosis of dissecting right vertebral artery pseudoaneurysm. to our knowledge, this maybe the first report of odontogenic pain as the first manifestation of vertebr...

STUDY DESIGN Comparative ex vivo biomechanical study. OBJECTIVE To determine the strength and stiffness of osteoporotic vertebral bodies subjected to compression fractures and stabilized via bipedicular injections of the following: 1) Simplex P (Stryker-Howmedica-Osteonics, Rutherford, NJ), 2) Simplex P formulated consistent with the practice of vertebroplasty (F2), or 3) BoneSource (Stryker-...

We examined the effect of alendronate treatment for 3-4 yr on risk of new fracture among 3658 women with osteoporosis enrolled in the Fracture Intervention Trial. This cohort included women with existing vertebral fracture and those with osteoporosis as defined by T score of less than -2.5 at the femoral neck but without vertebral fracture. All analyses were prespecified in the data analysis pl...

BACKGROUND Whether kyphoplasty or vertebroplasty is better for painful osteoporotic vertebral compression fracture is a widely debated issue. Studies on the comparison of the 2 approaches are relative limited and a wide variation exists in the patient population, study design, and results. These factors make it difficult for workers in this field to know the exact value of the 2 approaches. O...

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. ...

BACKGROUND AND PURPOSE Vertebroplasty is an effective treatment for painful compression fractures refractory to conservative management. Because there are limited data regarding the survival characteristics of this patient population, we compared the survival of a treated with an untreated vertebral fracture cohort to determine whether vertebroplasty affects mortality rates. MATERIALS AND MET...

INTRODUCTION While thoracolumbar fractures are common lesions, no strong consensus is available at the moment. OBJECTIVES The aim of this study was to evaluate the results of a minimal invasive strategy using percutaneous instrumentation and anterior approach in the management of thoracolumbar unstable fractures. METHODS 39 patients were included in this retrospective study. Radiologic eval...

AIM To prospectively investigate the role of MR spectroscopy (MRS) and diffusion-weighted magnetic resonance imaging (DWI) in assessing vertebral marrow changes in postmenopausal women. MATERIALS AND METHODS Fifty postmenopausal women, who underwent dual-energy x-ray absorptiometry of the spine, were divided into three bone density groups (normal, osteopenia, and osteoporosis) based on T-scor...

1. When angiotensin was infused at low rates into the vertebral arteries of anaesthetized dogs, it raised the blood pressure. When infused at similar rates intravenously or into the internal carotid artery it either did not change blood pressure, or raised it only very slightly. The difference in response was highly significant over the range of 1-50 ng kg' min'. 2. During intravenous infusion ...

Abstract Background This is a Clinical Practice Guideline update released by the Egyptian Academy of Bone Health and Metabolic Diseases. It does not replace clinical practice guidelines published for treatment osteoporosis in 2021, but it entails specific recommendations selective criteria romosozumab as another pharmacological agent postmenopausal osteoporosis. has been issued, part, due to im...
