[Vertebroplasty--state of the art].

BACKGROUND

Percutaneous vertebroplasty (PVP) using PMMA (polymethyl methacrylate) was first described in 1987 by Gallibert and Deramond for the treatment of vertebral body instability in patients with aggressive forms of vertebral hemangioma. Other types of painful osteolytic bone lesions, such as osteoporotic vertebral fractures and vertebral metastasis are in the meantime more commonly treated using this method.

METHODICAL INNOVATIONS: Within the last few years, this technique has become widely accepted and it is proposed for osteolytic bone lesions in areas that are more difficult to approach surgically, e.g., the pelvis and sacrum.

EFFICACY: Rapid pain relief and resulting stability have conferred an important role upon osteoplasty especially in palliative tumor-treatment for patients with shortened expected life spans. In addition, combined treatment of painful osteolytic metastases with image-guided thermoablation and percutaneous cement injection has been shown to be a safe palliative modality in the therapy of nonresectable tumors.
