To examine factors which affect local recurrence of osteoid osteomas treated with percutaneous CT-guided radiofrequency thermocoagulation.
A prospective study was carried out on 45 patients with osteoid osteoma who underwent percutaneous radiofrequency thermocoagulation with a minimum follow-up of 12 months.
There were seven local recurrences (16%); all occurred within the first year. Local recurrence was significantly related to a non-diaphyseal location (P<0.01). There was no significant relationship (P=0.05) between local recurrence and age of the patient, duration of symptoms, previous treatment, size of the lesion, positive biopsy, radiofrequency generator used or the number of needle positions. There were no complications.
Osteoid osteomas in a non-diaphyseal location are statistically more likely to recur than those in a diaphyseal location when treated with CT-guided percutaneous radiofrequency thermocoagulation. This relationship between local recurrence and location has not been previously reported.
探讨经皮CT引导下射频热凝治疗骨样骨瘤后影响局部复发的因素。
对45例行经皮射频热凝治疗的骨样骨瘤患者进行前瞻性研究，随访时间至少12个月。
有7例局部复发（16%）；均发生在第1年内。局部复发与非骨干部位显著相关（P<0.01）。局部复发与患者年龄、症状持续时间、既往治疗、病变大小、活检阳性、所用射频发生器或穿刺针位置数量之间无显著相关性（P=0.05）。无并发症发生。
经CT引导下经皮射频热凝治疗时，非骨干部位的骨样骨瘤在统计学上比骨干部位的骨样骨瘤更易复发。局部复发与部位之间的这种关系此前未见报道。
