Abstract
AIM: The aim was to evaluate laser photocoagulation and the use of the Bonopty needle system in the treatment of osteoid osteoma. MATERIALS AND 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). CONCLUSION: 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. Copyright 2003 The Royal College of Radiologists
