The Effect of Radiofrequency Ablation on Pain Score and Non-Steroidal Painkiller Use in Osteoid Osteoma Patients.

Aim CT-guided radiofrequency ablation (RFA) is among the thermal ablative procedures and provides great benefits with a minimally invasive procedure. In this prospective study, we aimed to reveal the significance of a multidisciplinary method in reducing the recurrence and complications in osteoid osteoma patients with CT-guided RFA performed by a team of experts in the field. Materials and methods A total of consecutive 40 patients with osteoid osteoma were prospectively evaluated and treated with CT-guided RFA. Before and the post ablation the visual analog scale (VAS) and use of nonsteroidal anti-inflammatory drugs (NSAIDS) were compared. Results Post-ablation VAS of the patients at the 1st week and 3rd month after the procedure decreased significantly (p < 0.01) compared to the pre-ablation. The frequency of NSAID use after the ablation decreased significantly (p < 0.01) compared to the pre-ablation time. The pre-procedure NSAID use of our patients included in the study was average 6.93 per week, the NSAID use in the 3rd month post-procedure controls was average 0.53 per week. Recurrence was detected in 4 of our patients, 36 patients had complete recovery. Conclusion Radiofrequency ablation is an effective treatment method in the management of osteoid osteomas. Radiofrequency ablation has low recurrence rates and provides rapid regression in patients’ pain after treatment.
