To review symptoms and imaging findings of proximal femoral osteoid osteomas (OO); to analyse the results of a thermal ablation technique for radiofrequency of the nidus in this location; and to describe usefulness of ultrasound guidance in selected cases.
Descriptive and retrospective study consisting of 8 patients with OO in the proximal epiphysis of the femur, which were treated by thermal ablation of the nidus with radiofrequency waves from 1998 to 2004.
The mean pain period until the performance of the thermal ablation was 11.5 months (range 5-18 months). There were no complications, and all patients stated that the pain was gone by the day following the procedure, with some discomfort during the first week, except for one where it lasted more than one month due to technique difficulties. At present, with a mean follow up of 6 years and 2 months (range 6-190 months), all patients remain asymptomatic and live a rigorous normal life.
Thermal ablation with CT-guided radiofrequency waves is a safe, effective and efficient procedure.
Normal appearance of a proximal femoral OO does not differ significantly from other location osteomas and its diagnosis is easier with previous knowledge. Thermal ablation of the nidus with radiofrequency waves, that may be performed using ultrasound guidance, appears to be the elective treatment of choice due to its efficiency and minimum morbidity.
回顾股骨近端骨样骨瘤（OO）的症状和影像学表现；分析该部位病灶热消融技术的射频治疗结果；并描述超声引导在特定病例中的作用。
进行描述性和回顾性研究，纳入8例股骨近端骨骺骨样骨瘤患者，这些患者在1998年至2004年间接受了病灶的射频热消融治疗。
直至进行热消融时的平均疼痛期为11.5个月（范围5 - 18个月）。无并发症发生，所有患者均表示术后次日疼痛消失，第一周有一些不适，但有1例因技术困难疼痛持续超过1个月。目前，平均随访6年2个月（范围6 - 190个月），所有患者均无症状，过着正常的严格生活。
CT引导下射频热消融是一种安全、有效且高效的手术。
股骨近端骨样骨瘤的表现与其他部位骨瘤无显著差异，有既往知识的话其诊断更容易。使用超声引导进行病灶的射频热消融，因其有效性和低发病率，似乎是首选的治疗方法。
