RADIO FREQUENCY ABLATION (RFA) OF OSTEOID OSTEOMA
What is osteoid Osteoma:
- It is a relatively common, benign but painful bone tumor. It occurs mainly in children and young adults.
How it can be treated:
- Percutaneous CT-guided ablation is treatment of choice for osteoid osteoma.
- RFA is a minimally invasive alternative to the surgical and medical management of osteoid osteoma.
How RFA performed:
- In this procedure, under local anaesthesia CT guided insertion of needle into tumor is done followed by insertion of probe for RFA.
- RFA probe heat it up for several minutes using radiofrequency energy, which destroys tumour completely by frictional energy.
What are benefits of RFA:
- Most patients experience complete pain relief within the first few days after the procedure.
- RFA causes minimal damage to the bone and surrounding muscle.
Preparation for procedure:
- Few basic blood investigations like CBC, PT/INR, viral markers.
- Bring all the records including imaging record.
- Signing consent form.
What are risks:
- Muscular hematoma, skin burn, nerve injury, infection (<1 case in 1000).
