title: Percutaneous laser photocoagulation of osteoid osteomas under CT guidance.
abstract: OBJECTIVE
  The aim was to evaluate laser photocoagulation and the use of the Bonopty needle system in the treatment of osteoid osteoma.
  
  
  METHODS
  Five patients with osteoid osteomas were treated with computed tomography (CT)-guided, percutaneous laser photocoagulation using the Bonopty biopsy system.
  
  
  RESULTS
  Complete pain relief was obtained in four patients. In one patient, pain persisted until the 6 weeks follow-up but resolved within 24 h of repeating the procedure. There were no complications, and patients remained symptom free at follow-up of 4-23 months (mean, 14 months).
  
  
  CONCLUSIONS
  CT-guided laser photocoagulation of osteoid osteoma is a minimally invasive technique that represents a cost-effective alternative to surgical excision. The Bonopty needle system allows successful penetration of the sclerotic bone surrounding the nidus with manual pressure alone.
