BACKGROUND: Because of an aging population,osteoporotic vertebral fractures are becoming more frequent.Conservative therapy was considered the gold standard for treating osteoporotic vertebral compression fractures (OVCFs) in the past. Percutaneous vertebroplasty (PVP) or balloon kyphoplasty (BKP) as minimally invasive techniques are new treatments that are widely used for painful OVCFs. However, an increase in new vertebral compression fractures at non-treated levels following augmentation is of concern...

BACKGROUND: In case of complex vertebral fractures, posterior fixation is often required for correction of deformity and instability. Fixation is commonly supported by balloon kyphoplasty (BKP) anterior. A development of BKP is radiofrequency-targeted vertebral augmentation (RF-TVA), which leads to comparable results for augmentation and pain relief. OBJECTIVE: This prospective study evaluates the outcome of posterior fixation combined with RF-TVA or BKP, respectively...

BACKGROUND: 30% of myeloma patients suffer from vertebral compression fractures (VCF). Consequently, augmentation often becomes inevitable to prevent further problems. This study evaluated the interaction of radiation therapy (RT) and radiofrequency kyphoplasty (RFK) in the treatment of myeloma associated VCF. METHODS: Eighty-six myeloma patients with VCF were treated with RFK followed by radiation therapy (RFK group) or vice versa (RT group). Visual analgoue scale (VAS), Oswestry-Disability-Index (ODI), vertebral height and kyphosis angle were assessed preoperatively, 3-4 days, 3 and 6 months postoperatively...

Background: The perception of back pain subjective is hard for physicians to measure. For this reason, questionnaires are an important instrument to evaluate the pain 1. The main point of this study was to verify differentiation of pain symptoms in patients with different pain mechanisms. The most important parameter was the PainDetect questionnaire, which can differentiate between nociceptive and neuropathic pain. Additional parameters were measured before and after surgery to characterise pain symptoms in detail...

Kyphoplasty is a therapeutic option for pain relief in the setting of compression fractures. Cement extravasation into adjacent disks is a common occurrence. The biomechanical and clinical consequences of cement in the disks currently are unknown. This study investigated the biomechanical effects of cement extravasation into the intervertebral disk in a human cadaveric model. Seven thoracolumbar and lumbar embalmed human cadaveric motion segments were evaluated in axial rotation, right and left lateral bending, and flexion and extension...

Adjacent vertebral fractures are common in patients with osteoporotic vertebral compression fractures (OVCFs) after kyphoplasty. This finite element study was to examine whether short segment pedicle screw fixation (PSF) with kyphoplasty may decrease the fracture risk of the treated and adjacent non-treated vertebrae after kyphoplasty for OVCFs. By simulating cement augmentation with or without short segment pedicle screw fixation (PSF), two tridimensional, anatomically detailed finite element models of the T10-L2 functional spinal junction were developed...

BACKGROUND: Balloon-assisted kyphoplasty (BAK) is a well-accepted treatment for symptomatic vertebral compression fractures (VCF) secondary to osteoporosis. Some have raised a concern of an increased incidence of adjacent fractures due to alterations in spine biomechanics after cement augmentation. The incidence of subsequent VCFs following BAK is poorly understood. The aim of this study was to investigate the timing, location, and incidence of new VCFs following BAK and to identify risk factors associated specifically with the occurrence of new adjacent level fractures...

BACKGROUND: Percutaneous access to the vertebral bodies is commonly done via the transpedicular approach for both diagnoses and treatment of spinal pathology. While this approach is effective in most cases, it is difficult in certain situations such as a patient with obstructing hardware from prior surgery. OBJECTIVES: To investigate and illustrate an alternative to the typical percutaneous access to the vertebral body via an extrapedicular approach and to determine the complications associated with this approach...

BACKGROUND: Kyphoplasty has been proven to be an efficient method to relieve patient suffering from osteoporotic vertebral compression fractures (OVCFs). Because of its technological superiority, unilateral kyphoplasty consumes less operative time and bone cement than traditional bilateral kyphoplasty. However, there is controversy about which method is most efficient in the treatment of OVCFs. Thus, an overall analysis should be performed to shed light on the facts corroborating both procedures...

Vertebral compression fractures are caused by many factors including trauma and osteoporosis. Osteoporosis induced fractures are a result of loss in bone mass and quality that weaken the vertebral body. Vertebroplasty and kyphoplasty, involving cement augmentation of fractured vertebrae, show promise in restoring vertebral mechanical properties. Some complications however, are reported due to the performance characteristics of commercially available bone cements. In this study, the biomechanical performance characteristics of two novel composite (PMMA-CaP) bone cements were studied using an anatomically accurate human cadaveric vertebroplasty model...

Percutaneous kyphoplasty has a well-established role in the treatment of pathologic fractures in patients with multiple myeloma. Despite this, there is a scarcity of literature surrounding its use and efficacy in the sacrum. We present a case of successful symptom resolution in a patient with painful sacral fracture following sacroplasty, and review the existing literature.An 81-year-man with multiple myeloma presented to the hematology/oncology clinic with a history of excruciating pain while seated. The impact of this pain on his quality of life subjectively was rated to be particularly high...

BACKGROUND: Vertebral compression fractures are a common result of osteoporosis and osteopenia secondary to steroid use and chemotherapy treatment. Balloon kyphoplasty is a treatment option with good to excellent results well described in adults. Although a few recent studies have been published regarding the use of kyphoplasty in children, no formal indication exists for the pediatric population. The purpose of this study is to describe the outcomes of 3 chronically ill children with intractable pain from vertebral compression fractures, managed with kyphoplasty...
