Bone tumors

Benign tumor of osteoid osteoma 

Osteoid osteoma is a benign tumor that grows in bone tissues and can be diagnoses with symptoms such as pain in the bones, movement disorder of the organ and, in more severe cases, insomnia due to severe pain. 

Radio-frequency ablation (RFA) of osteoid osteoma 

When the pain intensifies in the patient, the tumor will be diagnosed by seeing a doctor and carrying out imaging. Then, radio-frequency ablation (RFA) of osteoid osteoma will be recommended for treatment. Today, this method is the best treatment method for this tumor. 
In this method, the tumor nucleus will be ablated and disabled with radio waves and the patient will not feel pain any further. 

How is radio-frequency ablation (RFA) of osteoid osteoma performed? 

The exact location of lesion will be determined and marked with needle under the guidance of CT scan. Then, electrode (RF needle) will be inserted into the tumor nucleus and it will be ablated with radio waves at the specified time. 

Advantages of radio-frequency ablation

In the past, this tumor was treated through open surgery. That is, bone was carved to remove the lesion nucleus. A long time after the surgery, the operated organ was places in plaster and the patient has numerous problems for performing daily activities for months. But today, this procedure will be performed without the removal of the bone tissue and only by making a small 2mm hole and the patient can return to the daily activities after two days of rest. 

Anesthesia during the surgery 

Radio-frequency ablation of osteoid osteoma requires anesthesia. That is because the ablation of tumor nucleus is performed with radio waves at a temperature of 90 degrees, which is intolerable and requires anesthesia. 

Preparations for surgery 

Pre-operative fasting for about 6 hours 
Taking shower and shaving the lower limbs 
Having the relevant medical records 
The presence of a companion for performing the administrative affairs 
Performing coagulation tests 

Tumor recurrence after the surgery 

The success rate of this surgery in one session is 96%. In 4% of cases where recurrence occurs, the surgery will be repeated in the same way. Tumor recurrence will be treated with 100% success after two sessions. 

Resting after surgery
The patient needs to rest for two days and then can return to their daily activities.

Referral and follow-up treatment
Pain is normal after a week, if pain continues after a week, need to be present.
