Radiofrequency of Spinal Metastases/Vertebroplasty

The spine is one of the most common sites of metastasis. Vertebral bodies involved by the tumor may become painful and may eventually fracture. Surgical intervention with reconstruction of the spinal column is indicated only if the tumor causes compression of the spinal cord or instability of the spine. Other treatment options are radiation therapy and sometimes chemotherapy. RF Coablation is used to shrink the spinal metaseses, then Vertebroplasty is performed. Coblation uses radiofrequency energy to excite the electrolytes in a conductive medium such as saline solution, creating a precisely focused plasma. The energized particles in the plasma have sufficient energy to break down molecular bonds, excising or dissolving soft tissue at relatively low temperatures (typically 40° C to 55° C), thereby preserving the integrity of surrounding healthy tissue. An interventional radiologist inserts a needle through a small incision in the back, directing it under fluoroscopy (continuous, moving X-ray imaging) into the fractured vertebra. After shrinking the tumor, the physician then injects a medical-grade bone cement into the vertebra. The cement hardens within about 15 minutes and stabilizes the fracture. This treatment improves pain, prevents further collapse of the vertebra, and restores mobility. This can improve back pain within hours of the procedure, provides long-term pain relief and has a low complication rate.





About Interventional Radiology

Interventional radiologists are board-certified physicians who specialize in minimally invasive, targeted treatments that have less risk, less pain and less recovery time compared to open surgery. They use their expertise in interpreting X-rays, ultrasound, MRI and other diagnostic imaging studies to understand, visualize and diagnose the full scope of the disease's pathology and to map out the procedure tailored to the individual patient. Then during the procedure, they image as they go to guide tiny instruments, such as catheters, through blood vessels or skin, to treat diseases at the site of the illness nonsurgically.

Interventional radiology is a recognized medical specialty by the American Board of Medical Specialties. Interventional radiologists complete preliminary training in Diagnostic Radiology and advanced training in Vascular and Interventional Radiology. The American Board of Radiology certifies their specialized training.
