title: Radiofrequency ablation of osteoid osteomas: analgesia and patient satisfaction in long-term follow-up.
abstract: OBJECTIVE
  To review the long term clinical outcomes in the treatment of osteoid osteoma (OO) using radiofrequency ablation (RFA).
  
  
  METHODS
  Our retrospective study included 59 patients who were treated in the period from April 2001 to December 2012 due to a symptomatic OO using RFA. Here, the occurrence of complications and postoperative recurrence, as well as postoperative patient satisfaction were examined. Patients satisfaction was assessed by means of a telephone interview with the visual analogue scale (VAS).
  
  
  RESULTS
  Mean follow-up was 50 months (2 - 116 months). The average size of the nidus was 6 mm (range 2 - 14 mm). After initial radiofrequency ablation 11.8 % (7/59) of patient showed a recurrence of symptoms. Symptoms could successfully be treated by a second ablation in 5 patients. Assisted success rate was therefore 96.6 % (57/59). The complication rate was 5.1 % (2 major and one minor complication). Furthermore we report a very high patient satisfaction and acceptance of therapy.
  
  
  CONCLUSIONS
  RFA is a very successful therapy of symptomatic OOs with a high patient satisfaction.
  
  
  CONCLUSIONS
  ▶ Osteoid osteomas (OO) are rare benign bone tumors of the childhood and adolescence. ▶ Treatment of OOs with minimal-invasive radiofrequency ablation (RFA) shows a high patient satisfaction. ▶ RFA is by now the standard therapy of symptomatic OOs.
