To evaluate a percutaneous technique for in situ destruction of osteoid osteoma.
Radio-frequency ablation was performed in 18 patients with osteoid osteoma (17 male, one female; age range, 8-42 years). Diagnosis was established by means of clinical and radiographic features and confirmed by means of needle biopsy findings. No attempt was made to remove the lesion. A small radio-frequency electrode introduced into the lesion through the biopsy track was used to produce thermal necrosis of a 1-cm sphere of tissue.
Symptoms were completely relieved in 16 (89%) of 18 patients. In one patient, a second procedure was required for pain relief. All but two patients underwent treatment as outpatients: These two were hospitalized for 1 night only. All patients resumed normal daily activities immediately. No casts or external supports were required; there were no complications. Twelve patients were followed up for more than 1 year. There were no recurrences
Radio-frequency ablation of osteoid osteoma is a promising alternative to surgery in selected patients.
评估一种用于原位破坏骨样骨瘤的经皮技术。
对18例骨样骨瘤患者（男17例，女1例；年龄范围8 - 42岁）进行射频消融。通过临床和影像学特征进行诊断，并经针吸活检结果证实。未尝试切除病变。通过活检通道将一个小的射频电极插入病变部位，以产生1厘米组织球的热坏死。
18例患者中有16例（89%）症状完全缓解。1例患者需要进行第二次治疗以缓解疼痛。除2例患者外，所有患者均作为门诊患者接受治疗：这2例仅住院1晚。所有患者均立即恢复正常日常活动。无需石膏或外部支撑；无并发症发生。12例患者随访超过1年，无复发。
对于选定的患者，射频消融骨样骨瘤是一种有前景的手术替代方法。
