Osteoid Osteoma Treated with Radiofrequency Ablation

Abstract

Purpose. Our aim is to evaluate the results of treatment with computed tomography (CT) guided percutaneous radiofrequency ablation for osteoid osteomas which were localized in a difficult area for operation. Materials and Methods. Glenoid, distal tibia, humerus shaft, proximal humerus, and in third finger of the hand proximal phalanx were involved in one patient. Proximal femur was involved in three patients, distal femur was involved in three patients, and proximal tibia was involved in two patients. 9 males and 4 females were aged 4 to 34 years (mean age: 18.5 years). All patients had pain and were evaluated with X-rays, CT, bone scintigraphy, and MRI. In all patients, RF ablation was performed with local anesthesia. The lesion heated to 90°C for 6 minutes. Results. All of the patients achieved complete pain relief after ablation and were fully weight bearing without any support. In all patients, there was soft tissue edema after the procedure. During follow-up, all patients were free from the pain and there was no sign about the tumor. There was no other complication after the process. Conclusion. CT guided RFA is a minimally invasive, safe, and cost-effective treatment for osteoid osteoma placed in difficult area for surgery.

Subperiosteal Osteoid Osteoma of the Knee: Case Report

“…They may occur in any bone, but predominantly occur in the appendicular skeleton (4). In over 50% of cases, the lesions centered on the cortex of femoral and tibial diaphysis (6). In our case, the nidus was located in the supracondylar subperiosteal area of the femur.…”

Radiofrequency ablation of osteoid osteoma: Aiming for excellent outcomes in an Australasian context

“…Over the last 20 years, radiofrequency ablation (RFA) has become the treatment of choice for osteoid osteoma (OO) . The reasons for this include its availability, low morbidity and high success rate, including in areas that are difficult to treat surgically . Relatively little has been written about this technique in Australasia, with quite high rates of recurrence reported in one previous series …”

“…[1][2][3][4][5][6][7] The reasons for this include its availability, low morbidity and high success rate, including in areas that are difficult to treat surgically. 8 Relatively little has been written about this technique in Australasia, with quite high rates of recurrence reported in one previous series. 7,9 The purpose of this article is to present a series of patients treated in an Australasian centre in which the primary success rate of RFA for OO has been very high and the complication rate very low.…”

“…Development of minimally invasive therapies has greatly improved treatment options. Percutaneous radiofrequency ablation (PRFA), the most commonly used of these therapies [5][6][7] , was introduced by Rosenthal et al in 1992 8 . PRFA has the advantages of involving little surgical trauma and enabling accurate positioning of the nidus; however, it also has some problems and is not suitable for all patients.…”
