Currently the “Gold standard treatment” of Osteoid Osteoma
Radiofrequency Ablation’ (RFA) minimally invasive procedure
How is RFA performed?
- Day Care basis
- Under local anaesthesia and/or general anaesthesia
- Diagnosis of Osteoid osteoma is confirmed under the CT scan.
- Small Scar (Similar to Core Needle Biopsy)
- In a percutaneous manner, Core needle biopsy is done under CT.
- RFA probe is inserted into the nidus and the area is burned by high temperature of 80-90 degree Celsius for 2-3 minutes under controlled environment.
- In situations of deep seated lesion or exuberant periosteal reaction, a drill is used to enter the nidus.
- The damage to surrounding bone is minimal.
- The individual can resume normal activities the same day with 95 % pain relief.
What is the recurrence rate of RFA?
The risk of recurrence has been documented as 3-10 %.
The recurrence is attributed to long nidus (greater than 10 mm) or wrong localization of the nidus or residual disease.
Can all osteoid osteomas be treated by RFA?
- Long nidus (>10 mm) may need multiple RFA or be surgical removal
- Spinal osteoid osteomas are not suitable for this technique due to the closeness of vital structures.
- Juxtarticular osteoid osteomas may be treated with caution due to resulting effusion and joint inflammation.
