CT guided RadioFrequency Ablation in 24 patients with spinal osteoid osteomas J.A.M Bramer, dep. Orthopedic surgery P.D.S. Dijkstra, dep. orthopedic surgery W.R.Obermann, dep. radiology A.H.M. Taminiau, dep. orthopedic surgery
CTOS 2005 Osteoid Osteoma in the spine Benign Nidus < 20 mm 10% in spine Pain Scoliosis
CTOS 2005 Open surgery Difficult localization Incomplete excision High recurrence rate High complication rate Ozaki, CLINICAL ORTHOP. REL. RES. 2002 Number 397, 394–402
CTOS 2005 Radio Frequency Ablation RF ablation under CT guidance Bonopty drilling system Radi Medical Systems, Uppsala, Sweden RF ablation probe Radionics-RFG3C RF-lesion Generator System, Burlington, USA
CTOS 2005 Conclusion CT-guided RF ablation of spinal osteoid osteomas is a successful minimal invasive procedure It is safe if the thermo probe is positioned at least 5 mm from vital structures Open surgery in case of tumor adherent to nerve root
The combination of percutaneous radiofrequency heat ablation and vertebroplasty seems to be a promising, feasible, minimally invasive technique in the treatment of spinal metastases with cortical defects
