RADIOFREQUENCY ABLATION FOR RARE OSTEOID OSTEOMA OF THE LESSER TROCHANTER IN AN ADOLESCENT: A CASE REPORT

Osteoid osteoma is a benign but painful bone tumor, predominantly affecting young individuals [13]. Although it frequently occurs in the long bones of the lower limbs, involvement of the lesser trochanter is rare and poses diagnostic and therapeutic challenges due to its deep location and proximity to vital neurovascular structures [6]. This report presents a case of a young adult with persistent hip pain, ultimately diagnosed with osteoid osteoma of the lesser trochanter using computed tomography [12]. The patient underwent CT-guided percutaneous radiofrequency ablation (RFA), resulting in immediate symptom relief and full recovery without recurrence during follow-up [4]. This case highlights the utility of minimally invasive RFA as a safe, effective alternative to surgical excision, especially in anatomically challenging sites.
