STUDY DESIGN A retrospective cohort study. PURPOSE To analyze differences in between the unipedicular vs. bipedicular balloon kyphoplasty for the treatment of multiple myeloma lesions. OVERVIEW OF LITERATURE Both vertebroplasty and kyphoplasty are reported to be effective for the treatment of vertebral compression fractures in multiple myeloma patients. Kyphoplasty is often performed with a...

BACKGROUND AND PURPOSE Previous ex vivo biomechanical studies have shown that kyphoplasty with polymethylmethacrylate cement increases vertebral body (VB) strength and restores VB stiffness and height after compression fracture. The purpose of the current study was to determine if a hydroxyapatite cement used as a void filler during kyphoplasty provides mechanical stabilization similar to that ...

BACKGROUND AND PURPOSE Previous studies evaluating vertebral augmentation procedure costs have not made detailed comparisons between vertebroplasty and kyphoplasty. Our study contrasts hospital costs for vertebroplasty versus kyphoplasty for the treatment of vertebral compression fractures in routine clinical practice in the United States. MATERIALS AND METHODS This retrospective cohort study...

BACKGROUND The causes of subsequent vertebral fractures after kyphoplasty are debated. It is reported that most new vertebral fractures after kyphoplasty develop in adjacent vertebrae. OBJECTIVES We explored whether kyphoplasty increases the incidence of adjacent vertebral fractures and identified risk factors for new vertebral compression fractures (VCFs) after kyphoplasty. STUDY DESIGN Re...

PURPOSE To identify the incidence of new vertebral compression fractures in women after kyphoplasty and to analyze influential factors in these patients. MATERIALS AND METHODS One hundred and eleven consecutive female patients with osteoporotic vertebral compression fractures (VCFs) underwent kyphoplasty at 137 levels. These patients were followed for 15.2 months postoperatively. For the surv...

STUDY DESIGN A retrospective study. PURPOSE The aim of this study is to compare the efficacy and outcome of vertebroplasty compared with unipedicular and bipedicular kyphoplasty for the treatment of osteoporotic vertebral compression fractures in terms of pain, functional capacity and height restoration rates. OVERVIEW OF LITERATURE The vertebroplasty procedure was first performed in 1984 f...

BACKGROUND AND PURPOSE There are few comparative studies regarding morphologic changes after kyphoplasty and vertebroplasty. The purpose of this study was to compare restoration of vertebral body height and wedge angle and cement leakage with kyphoplasty and vertebroplasty in osteoporotic compression fractures. MATERIALS AND METHODS Forty patients (57 vertebrae) were treated with kyphoplasty,...

BACKGROUND AND PURPOSE Vertebroplasty and kyphoplasty can be associated with significant radiation exposure to the operator. We compared the exposure levels to an operator performing vertebral fracture augmentation with vertebroplasty and kyphoplasty, to assess a cement injection and a monitoring technique designed to reduce this exposure. METHODS A neuroradiologist performed 189 consecutive ...

This study prospectively compared the efficacy of kyphoplasty using a Jack vertebral dilator and balloon kyphoplasty to treat osteoporotic compression fractures between T10 and L5. Between 2004 and 2009, two groups of 55 patients each underwent vertebral dilator kyphoplasty and balloon kyphoplasty, respectively. Pain, function, the Cobb angle, and the anterior and middle height of the vertebral...

OBJECTIVE Although the majority of available evidence suggests that vertebroplasty and kyphoplasty can relieve pain associated with vertebral compression fractures (VCFs) and improve function, some studies have suggested results are similar to those of placebo. The purpose of this meta-analysis was to compare the outcomes of vertebroplasty and kyphoplasty with conservative treatment in patients...
