Percutaneous combination therapy of radiofrequency and alcohol ablation in osteoid osteoma is very effective
Clin Rad (2007). 62: 268-273
Akhlaghpoor S et al (Clinical Radiology 2007. 62:268-273 ) from Noor Medical Imaging Center, Iran treated 54 patients od osteoid osteoma with 11 G radiofrequency-compatible coaxial needle and 2 mm coaxial drill system and 1.0 cm active tip 17 G non-cooled radiofrequency needle. They performed RFA at 90 °C for 6 min. After needle removal, they injected 0.5–1.0 ml absolute alcohol into the nidus using a 20 G needle. The patients were discharged within 24 h.
They claim technical success rate of 100%. Complications occurred in about 4% (2 patients) and they were mild local cellulitis and small zone peripheral paresthesia. The follow-up period was in the range of 13–48 months. Pain relief and return to normal activities were seen in 52 of 54 patients (96%). Pain recurred in 2 patients after 1 and 3 months of pain free period. A second RFA and alcohol ablation was performed achieving successful results.
They concluded that the percutaneous osteoid osteoma treatment with combination of radiofrequency and alcohol ablation was effective with high success rate and also persistent or recurrent lesions could be effectively re-treated.
