Percutaneous vertebroplasty in tumoral osteolysis

Percutaneous vertebroplasty is a minimally invasive, radiologically guided procedure in which bone cement is injected into structurally weakened or destructed vertebrae in order to achieve additional biomechanical stability. In addition to treating osteoporotic vertebral fractures, this technique gains popularity to relieve pain by stabilizing vertebrae compromised by, for example, metastases, aggressive hemangiomas or multiple myeloma that are at risk of pathologic fracture. Since conservative treatment with narcotic analgesics, bed rest, biphosphonates and back bracing for several weeks is often ineffective and the analgesic effect of radiation therapy is delayed, percutaneous vertebroplasty may play a beneficial role in the management of metastases to the spine.
