Objectives: This study aims to present the importance of a multidisciplinary approach to radiofrequency ablation (RFA) treatment in osteoid osteoma (OO) patients by a team of experts in their field in preventing recurrence and complications.

Patients and methods: For this retrospective study, a team of two orthopedists, two interventional radiologists, and one anesthesiologist was established in January 2013 to manage the diagnosis, follow-up, and treatment process of patients with OO at Bakırköy Dr. Sadi Konuk Training and Research Hospital. A total of 27 patients (15 males, 12 females; mean age 22.9 years; range, 9 to 54 years) were treated by this team between February 2013 and September 2016. The anatomic localization included iliac crest in four patients, the femur in 12 patients, fibula in two patients, humerus in three patients, radius in one patient, tibia in three patients, talus in one patient, and metacarpal in one patient. The procedures were carried out by the same interventional radiologists, same orthopedic surgeons, and same anesthesiologist in the computed tomography (CT) unit under aseptic conditions. After appropriate anesthesia for the localization of OO, the patient was positioned on the CT bed and the localization of the lesion was confirmed with a CT scan mapping. Then, a bone penetration cannula was advanced and bone cortex was penetrated with a charged motor and Kirschner (K)-wire. When the cannula reached the nidus, it was replaced with RFA probe. Ablation of the nidus was performed for five minutes at 90°C.

Results: The mean follow-up period was 46 months (range, 25 to 66 months). Patients were evaluated with visual analog scale (VAS) scores preoperatively and at postoperative 15th day, sixth month, and first year. In the last evaluation of the study data, the patients were called by telephone and questioned whether there were any changes in their final status. The mean preoperative VAS score was 7.2. The mean postoperative VAS scores of the 15th day, sixth month, and first year were 1.3, 0.6, and 0, respectively. In the last follow-up, the OO-related pain completely disappeared and none of the patients had any recurrence. There was a significant difference between preoperative and postoperative 15th day and sixth month VAS score measurements.

Conclusion: Radiofrequency ablation treatment of OOs is a minimally invasive, safe, low-cost, and efficient method. We believe that with experienced teams and appropriate planning, RFA will take part in practice as the standard treatment of OO.
