title: Computed tomography-guided radiofrequency ablation is a safe and effective treatment of osteoid osteoma located outside the spine.
abstract: BACKGROUND
  The aim of this study was to evaluate the long-term clinical outcome after computed tomography (CT)-guided radiofrequency ablation (RFA) in patients diagnosed with osteoid osteoma (OO) located in the upper and lower extremities.
  
  
  METHODS
  The study population included 52 patients with a typical clinical history and radiologically confirmed OO who received CT-guided RFA treatment from 1998 to February 2014 at Aarhus University Hospital, Denmark. The clinical outcome was evaluated based on patient-reported outcome measures and medical record review.
  
  
  RESULTS
  The response rate was 52/60 (87%). Pain relief after the first RFA treatment was found in 46/52 (88%) of the patients and after re-RFA in 51/52 (98%) of the patients. One patient underwent open resection after RFA. No major complications occurred, and four patients reported minor complications in terms of small skin burn, minor skin infection and hypoaesthesia at the entry point. In all, 50 of 52 (96%) patients reported to be "very satisfied" with the RFA treatment.
  
  
  CONCLUSIONS
  CT-guided RFA is a safe and effective treatment with high patient satisfaction and it provides robust pain relief and improves the patients' quality of life. RFA should be the treatment of choice for most OO.
