Hip fracture after radiofrequency ablation therapy for bone tumors: two case reports

Radiofrequency ablation (RFA) has become a valuable therapeutic modality in cancer treatment over the last decade. In orthopedic surgery, RFA is used for the treatment of benign bone tumors and bone metastases. Complications are rare and, to our knowledge, bone fracture as a complication due solely to RFA has not been reported to date. In this report we describe two patients with a fracture in the calcar region of the femur as a complication of RFA treatment for bone malignancies. Since RFA is applied increasingly often, it is important to report this risk of fracture as a complication of treatment of lesions in the femoral calcar.
