Abstract

Background: Osteoid osteoma is a benign bone tumor composed of a nidus of woven bone and osteoid surrounded by osteoblasts and reactive zone of thickened cortical or trabecular bone and loose fibrovascular tissue.
Purpose: assessment the validity of radiofrequency ablation in managing osteoid osteoma.
Methods: This prospective study was conducted on 30 osteoid osteoma patients aged 4 to 37 years. All patients complained of night pain underwent X-rays, CT scans, bone scintigraphy, and MRI to confirm the diagnosis of osteoid osteoma. The lesion was heated to 90 degrees Celsius for 4-5 minutes. Post-procedure evaluations: decrease NSAIDs need and resolve swelling after radiofrequency ablation.
Results: The mean age of patients was 17 years, predominantly male distribution (60%). Most tumors were cortical (86.7%), located in the diaphysis (70%), the femur was the most affected bone (46.7%). The mean pre-procedure pain score was 7, which decreased to 1.3 in the first week and 0.9 in the 6th-month post-procedure. NSAID use decreased from 100% pre-procedure to only 10% post-procedure. In 76.7% of patients, the nidus size decreased and improved sclerosis.
Conclusions: RFA is a highly effective and minimally invasive treatment for osteoid osteoma with quick recovery.
