title: Osteoid osteoma of the calcaneus: percutaneous radiofrequency ablation.
abstract: Osteoid osteoma of the foot can pose particular problems in diagnosis, especially when positioned in a juxta-articular location. It can cause reactive synovitis and simulate arthritis without periostitis. An atypical presentation may delay diagnosis and thus delay treatment. Different modes of treatment have been described including medical management with nonsteroidal, antiinflammatory drugs, and open surgical resection with intralesional, marginal, or wide surgical margins. In recent years, several computed tomography-guided percutaneous techniques have been used to achieve ablation of the nidus with minimal tissue invasion. We report a case of a 39-year-old man with an 8-month history of persistent foot pain who underwent percutaneous radiofrequency ablation of an osteoid osteoma involving the calcaneus. The patient related an immediate relief of pain and had no recurrence of symptoms or the lesion at 3-year follow-up.
