Orthopaedic Surgery


Answer 4
  1. Percutaneous RFA. The femoral neck is the most common location for an osteoid osteoma. Computed tomography (CT)-guided localization and percutaneous RFA are often used to treat osteoid osteoma. RFA has a success rate of up to 90%, and several recent studies have documented the efficacy of RFA while also reporting decreased morbidity;2–4 however, appropriate facilities and trained staff are required. CT-guided localization and resection of the tumor or an en bloc excision are slightly more invasive, and there is the possibility of incomplete excision of the nidus. Radiation and chemotherapy are not indicated in the treatment of osteoid osteoma.
