[Radiofrequency treatment of an osteoid osteoma of the wrist: report of 2 cases].

Two cases of osteoid osteomas of the lunate and ulnar styloid process are described, treated by thermocoagulation. Follow-up was done clinically and by computed tomography (scanner) at one year, and clinically at three years. A quick and complete resolution of pain occurred in both cases, with bony sclerosis around the treated lesion on computed tomography, with no evidence of recurrence. A mild reduction in grip strength without functional impairment was noted in both cases, possibly due to a stronger controlateral dominant hand, and to a previous failed surgical excision in one case. No damage to neurovascular, musculotendinous or cutaneous structures occurred. Thermocoagulation of osteoid osteomas seems to be an efficient and safe technique even in critical and superficial anatomical regions such as the wrist.
