Osteoblastoma When Radiofrequency Ablation or Alternative Ablative Therapy Has Not Achieved Complete Pain Relief
This protocol addresses osteoblastoma in patients where a prior ablative intervention failed to deliver sustained pain control, and for whom a surgical approach is now indicated as the next step.
Previous Line — Failure Condition
Ablative therapies that may have been attempted include:
- CT-guided radiofrequency ablation (RFA)
- CT-guided cryoablation (CA)
- MR-guided focused ultrasound (MRgFUS)
- CT-guided laser ablation
Escalation to this line is triggered when those therapies fail to achieve: immediate resolution of nocturnal bone pain, complete pain relief at the 1-month follow-up, or absence of bone pain at the 12-month follow-up.
Next-Line Surgical Approach
This protocol is built around surgical excision performed under general anesthesia, with fluoroscopic localization of the lesion — how the resection is carried out, and what structural decisions follow, are detailed in the full protocol.
Treatment Goals
- Complete pain relief
- No tumor recurrence

- Usually, surgery is performed under general anesthesia.
- The accurate localization of the lesion is performed with fluoroscopy.
- Surgery consists of intralesional excision (curettage) or total excision.
- When the vertebral body is involved, intralesional excision (curettage) is performed to ensure maximal removal of the tumor and to minimize the risk of tumor recurrence.
