title: Osteoid osteoma of the acetabular fossa: five cases treated with percutaneous resection.
abstract: BACKGROUND
  Osteoid osteoma is a painful benign osteogenic tumour for which the treatment objective is surgical resection of the nidus. The acetabular fossa is an uncommon site of involvement where surgical access can prove challenging.
  
  
  METHODS
  We report a case-series composed of five patients with osteoid osteoma of the acetabular fossa treated with percutaneous bone resection and drilling under computed tomography guidance.
  
  
  RESULTS
  All five patients had an uneventful postoperative course with immediate pain relief that was sustained over time.
  
  
  CONCLUSIONS
  The outcomes achieved using our percutaneous technique compare favourably with those of other percutaneous methods, most notably regarding pain relief and patient tolerance of the procedure.
  
  
  CONCLUSIONS
  Percutaneous bone resection and drilling under computed tomography guidance proved effective for the treatment of osteoid osteoma involving the acetabular fossa.
  
  
  METHODS
  Level IV.
