    Abstract:
    UNLABELLED: THE PURPOSE OF THE STUDY was to evaluate interstitial laser photocoagulation for local destruction of osteoid osteoma, with computed tomographic (CT) guidance. MATERIAL AND METHODS: 28 patients (age range from 5 to 48 years) with presumed osteoid osteoma were treated with CT-guided interstitial laser photocoagulation of the nidus. A high power semiconductor diode laser (805 nm) with a 400 microns optical fiber was used. The fiber was introduced into the nidus through a 18-gauge needle. Around the fiber tip, well-defined coagulative necroses from 5 to 9 mm (energy delivery, 400-1000J) were obtained. RESULTS: 27 patients had complete pain relief, which was effective within 24 hours in 18 patients. One patient had pain recurrence after 6 weeks. The remaining nidus was treated secondarily with complete relief. Treatment was unsuccessful in one patient, and surgical excision was performed. All patients were followed up for more than 1 year, with no sign of recurrence. The only notable complication was a mild reflex sympathetic dystrophy of the wrist in one patient. Sclerosis of the nidus was observed 6-12 months after the procedure. CONCLUSION: Percutaneous interstitial laser photocoagulation of osteoid osteoma seems to be a promising, simple, precise, and minimally invasive alternative to traditional surgical and percutaneous ablations.
