Summary
Minimally invasive radio-frequency ablation offers a highly effective, non-invasive treatment for osteoid osteoma, achieving complete pain resolution and a 100% success rate in a two-year study.
Area of Science:
- Orthopedic Surgery
- Minimally Invasive Procedures
- Oncology
Background:
- Osteoid osteoma is a benign bone tumor causing significant pain.
- Traditional treatments can be invasive with longer recovery times.
Purpose of the Study:
- To evaluate the efficacy and safety of a novel percutaneous radio-frequency (RF) ablation technique for osteoid osteoma.
- To present two years of clinical experience with this minimally invasive approach.
Main Methods:
- 21 patients with osteoid osteoma underwent CT-guided RF ablation.
- A specialized needle electrode delivered targeted hyperthermia (90°C for 6 minutes) to the nidus.
- Post-procedure CT scans assessed treatment site density as an evolution index.
Main Results:
- Complete pain resolution was achieved in all patients within three weeks.
- No serious complications were reported during the follow-up period.
- Four patients reaching two-year follow-up showed a 100% success rate with no relapses.
Conclusions:
- Percutaneous RF ablation is a highly effective, minimally invasive, and cost-effective first-line treatment for osteoid osteoma.
- The technique allows for early weight-bearing and short hospital stays (one day).
- RF ablation offers a repeatable procedure with excellent clinical outcomes and symptom remission.
