To evaluate the efficiency and complication rate of two percutaneous treatments of osteoid osteomas, percutaneous trephine resection (PR) and interstitial laser ablation (ILA). Ethical review board was obtained for the retrospective study. One hundred and 26 patients were treated by PR (n = 26) or ILA (n = 100) under CT, with a median follow-up of 113 months for the PR group and 47 months for the ILA group. In the group treated by PR, the clinical success rate was 96% at 6-month and 95% at 24-month follow-up, with 12% (3/26) transient complications (one meralgia, two skin burns). One patient experienced immediate failure, and none had delayed failure. In the group treated by ILA, the clinical success rate was 96% at 6-month and 94% at 24-month follow-up, with 4% (4/100) transient complications (one common fibular nerve contusion, one hematoma, one infection and one tendinitis). Four ILA procedures were repeated, one because of initial failure and three because of recurrence (at 6.5, 15 and 32 months). Two were successful and two failed again. Failure was more frequent (p = 0.0094) in patients less than 18 years old, and in lesions with a nidus size of 12 mm or larger (p = 0.0022).
经皮环锯切除术（PR）和间质激光消融术（ILA）。本回顾性研究获得了伦理审查委员会的批准。100 名患者（ILA 组 100 例，PR 组 26 例）接受 CT 引导下的 ILA 或 PR 治疗，PR 组的中位随访时间为 113 个月，ILA 组为 47 个月。PR 组的临床成功率为 6 个月时 96%，24 个月时 95%，12%（3/26）出现短暂性并发症（1 例股外侧皮神经麻痹，2 例皮肤烧伤）。1 例患者即刻失败，无延迟失败。ILA 组的临床成功率为 6 个月时 96%，24 个月时 94%，4%（4/100）出现短暂性并发症（腓总神经挫伤 1 例，血肿 1 例，感染 1 例，肌腱炎 1 例）。4 例 ILA 手术重复进行，1 例因初始失败，3 例因复发（6.5、15 和 32 个月）。2 例成功，2 例再次失败。年龄小于 18 岁（p = 0.0094）和瘤巢大小为 12mm 或更大（p = 0.0022）的患者复发率更高。
