Objective. To evaluate rise in impedance during percutaneous radiofrequency thermocoagulation (PRFTC) of osteoid osteomas as a predictor of local recurrence. Design and Patients. A prospective study of 23 patients (24 PRFTC procedures) with minimum of 2.25-year followup (average 3.3 years). Average age 19.6 years (range 4-44), sex ratio 15 : 8 (male : female), 16 nondiaphyseal, 7 diaphyseal. Results. In 19 procedures, an increase in impedance was measured-no recurrences have occurred in this group to date. In 5 procedures, no increase in impedance was seen (3 non-diaphyseal, 2 diaphyseal), and 1 recurrence has been seen in this group to date. This difference is statistically significant with a P value of .05.
目的。评估骨样骨瘤经皮射频热凝术（PRFTC）期间阻抗升高作为局部复发预测指标的价值。设计与患者。对23例患者（24次PRFTC手术）进行前瞻性研究，随访时间至少2.25年（平均3.3年）。平均年龄19.6岁（范围4 - 44岁），性别比15∶8（男∶女），16例非骨干型，7例骨干型。结果。19例手术中测量到阻抗增加，该组至今无复发。5例手术中未见阻抗增加（3例非骨干型，2例骨干型），该组至今有1例复发。此差异具有统计学意义，P值为0.05。
