Summary
Radiofrequency ablation (RFA) using a three-dimensional (3D) navigation system is a safe and effective treatment for osteoid osteoma (OO). This minimally invasive technique achieved high success rates and significant pain relief in patients.
Area of Science:
- Orthopedic surgery
- Interventional radiology
- Oncology
Background:
- Osteoid osteoma (OO) is a benign bone tumor that can cause significant pain.
- Traditional treatments may involve surgical resection, carrying risks of morbidity.
- Radiofrequency ablation (RFA) has emerged as a less invasive alternative.
Purpose of the Study:
- To evaluate the clinical outcomes of RFA for osteoid osteoma (OO).
- To assess the efficacy and safety of using a three-dimensional (3D) navigation system during RFA.
- To report technical success, clinical success, and complication rates.
Main Methods:
- 32 patients with diagnosed osteoid osteoma underwent RFA guided by a 3D navigation system.
- Tumor localization, technical and clinical success, biopsy results, and complications were recorded.
- Follow-up duration ranged from 1 to 65 months, with a median of 18 months.
Main Results:
- All procedures were technically successful, with 96.8% clinical success and complete pain relief.
- Tumors were located in various bones, including femur and tibia.
- Complications occurred in 9% of patients (fractures, osteomyelitis), with one recurrence requiring repeat RFA.
Conclusions:
- Three-dimensional (3D) navigation enhances RFA accuracy for osteoid osteoma (OO), especially in complex anatomical areas.
- RFA with 3D navigation is a feasible and safe treatment option for OO.
- This technique offers precise needle placement and effective pain management.
