Radiofrequency ablation of osteoid osteoma in common and technically challenging locations in pediatric population

Abstract

Context:Percutaneous radiofrequency ablation (RFA) of osteoid osteoma has a high technical and clinical success rate. However, there is limited data on its use in the pediatric population, especially in technically challenging locations.Objective:To assess the safety and efficacy of computed tomography (CT)-guided percutaneous RFA of osteoid osteoma in pediatric population.Patients and Methods:From June 2009 to May 2014, 30 patients with osteoid osteoma were treated with CT-guided RFA in common (25 cases) and technically challenging (five cases: four near articular surface and one in sacrum) locations. Therapy was performed under general anesthesia with a three-array expandable RF probe for 6 min at 90°C and power of 60–100 W. The patients were discharged next day under instruction. The treatment success was evaluated in terms of pain relief before and after (1 day, 1 month, and 6 months) treatment.Results:Technical success was achieved in all patients (100%). Primary clinical success was 96.66% (29 of total 30 patients), despite the pediatric population and atypical location. One patient had persistent pain after 1 month and was treated successfully with a second procedure (secondary success rate was 100%). One patient had immediate complication of weakness of right hand and fingers extension. No delayed complications were observed.Conclusions:CT-guided RFA is relatively safe and highly effective for treatment of osteoid osteoma in pediatric population, even in technically difficult locations.

“…They concluded that RFA is a safe and highly effective modality of treatment in the pediatric population, even in technically difficult locations. 2 Our patient has benefitted immensely from this minimally invasive intervention following a failed conservative management.…”

The safety and the efficacy of computed tomography guided percutaneous radiofrequency ablation of osteoid osteoma

“…Percutaneous RFA-treatment is an outpatient procedure that does not require large dissections or bone excisions. This makes percutaneous interventional treatments advantageous 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 17, 18, 20, 21. Since the most of our patients were admitted from far-cities, we hospitalised them for one night for close follow-up of possible complications.…”

“…Recent studies have shown that CT-guided percutaneous RFA is beneficial and may be preferred for treatment of OO 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14. The purpose of this study is to report the efficacy and safety of RFA-treatment in OO in a cohort of large number of cases.…”

Benign Hand Tumors (Part I): Cartilaginous and Bone Tumors

“…34 Treatments for osteoid osteoma range from surgical treatment, such as curettage, to minimally invasive techniques, such as radiofrequency ablation. 35 Four patients at our institution were treated with curettage, followed by PMMA bone filler in 1 patient, and 1 patient underwent excision. The patient who received the PMMA bone filler recurred after 3 months and underwent repeated curettage of the lesion followed by repacking with PMMA.…”
