Background: Multiple myeloma (MM) is a blood system malignant tumor, which often leads to osteolytic bone destruction, and the vertebral column is the primary site of involvement. However, the efficacy and prognosis of percutaneous kyphoplasty/vertebroplasty (PKP/PVP) for simple vertebral pathological fractures in patients with multiple myeloma are not yet unified. The primary objective of this study was to investigate the efficacy and prognosis of PKP/PVP in the treatment of multiple myeloma patients with vertebral pathological fractures. Read More

Multiple new options are available in the palliation of bone metastases. Most of these techniques can be used in conjunction with radiation therapy either before or after and are now giving patients who have reached dose limitations new options. These techniques can also be used with vertebroplasty (VP) to increase structural stability post tumor ablation. Read More

Vertebral augmentation is among the current standards of care to reduce pain in patients with vertebral fractures (VF), yet a lack of consensus regarding efficacy and safety of percutaneous vertebroplasty and kyphoplasty raises questions on what basis clinicians should choose one therapy over another. Given the lack of consensus in the field, the American Society for Bone and Mineral Research (ASBMR) leadership charged this Task Force to address key questions on the efficacy and safety of vertebral augmentation and other nonpharmacological approaches for the treatment of pain after VF. This report details the findings and recommendations of this Task Force. Read More

The aim of the current study was to use a Bayesian network meta-analysis to evaluate the relative benefits and risks of balloon kyphoplasty (BK), percutaneous vertebroplasty (PVP), and non-surgical treatment (NST) for patients with osteoporotic vertebral compression fractures (OVCFs). The results demonstrate that for pain and functional status, PVP was significantly better than NST, while the three treatments did not significantly differ in other outcomes.

Introduction: BK, PVP, and NST are widely used to treat OVCFs, but preferable treatment is unknown. Read More

Percutaneous vertebroplasty (PV) is one of the available treatments for vertebral compression fracture (VCF). Polymethylmethacrylate (PMMA) is the most common bone substitute used in the procedure, but it has several disadvantages. Bioceramic material, such as hydroxyapatite (HA), has better biological activity compared to PMMA. Read More

J Neurointerv Surg 2018 Dec 14. Epub 2018 Dec 14.

Department of Neuroradiology, Papa Giovanni XXIII Hospital, Bergamo, Italy.

Objectives: To describe a new technique to obtain minimally invasive but efficient vertebral body (VB) reconstruction, augmentation, and stabilization in severe osteoporotic and neoplastic fractures, combining two pre-existing procedures. The implant of vertebral body stents (VBS) is followed by insertion of percutaneous, fenestrated, cement-augmented pedicular screws that act as anchors to the posterior elements for the cement/stent complex. The screws reduce the risk of stent mobilization in a non-intact VB cortical shell and bridge middle column and pedicular fractures. Read More
