Summary
CT-guided therapy offers precise, minimally invasive treatment for osteoid osteoma, improving patient outcomes. This technique ensures accurate nidus ablation and documentation, simplifying complex bone tumor procedures.
Area of Science:
- Orthopedic Surgery
- Interventional Radiology
- Oncology
Background:
- Traditional open resection for osteoid osteoma lacks precision.
- CT-guided therapy provides superior intraoperative localization and ablation documentation.
- Minimally invasive approaches reduce patient trauma.
Purpose of the Study:
- To evaluate the efficacy of CT-guided interventions for osteoid osteoma.
- To compare radiofrequency ablation and percutaneous resection under CT guidance.
Main Methods:
- Retrospective analysis of 52 patients treated between 1996-2005.
- Treatments included radiofrequency ablation (n=11) and CT-guided percutaneous resection (n=41).
- Mean follow-up was 31.3 months.
Main Results:
- Successful treatment of all 52 osteoid osteoma cases.
- 50 patients achieved long-term success after the initial procedure.
- Two patients required a second procedure due to initial nidus misidentification, both successfully treated.
Conclusions:
- CT-guided surgery simplifies osteoid osteoma treatment through precise localization and minimally invasive access.
- The technique is adaptable for tumor biopsies, offering documented paths and specimen retrieval.
- CT guidance enhances therapeutic precision and procedural ease for bone lesions.
