“…Through the years, several image-guided, minimally invasive interventions have been developed to treat OOs. CT-guided radiofrequency ablation (RFA) for OO [31], is one of the increasing numbers of minimally invasive alternatives to conventional operative procedures [10,31,38,42]. In one study limited to OOs in the upper extremity, the authors [37] reported complete resolution of pain without additional treatment in 76% of patients, equal to the minimum rate reported in a series not limited to any specific locations [8].…”

“…Several studies report the use of RFA for ablation of OO in usual and unusual locations [16,23,35,38]. In one study limited to OOs in the upper extremity, the authors reported complete resolution of pain without additional treatment in 76% of patients [37].…”

“…The two patients who discontinued medical treatment in their series had gastritis because of the NSAIDs and could not tolerate them [17]. Although patients with OO initially are treated with a trial of NSAIDs, or more specifically aspirin [38], most patients have operations within 1 to 3 years from the start of symptoms because of pain and intolerance of prolonged consumption of NSAIDs [7]. Our data suggest all patients were free of symptoms without need for a second procedure during the short followup.…”

Background Osteoid osteoma has a nidus surrounded by sclerotic bone with a size usually less than 20 mm. Its diagnosis is made on typical presentation of nocturnal pain and imaging findings. Excision of the niduses, which are often small and difficult to precisely identify, sometimes may result in resection of surrounding normal bone. Minimally invasive percutaneous treatments have been used to try to minimize resection of normal bone. Although minimally invasive radiofrequency ablation generally relieves pain, its ability to relieve pain is less well known in locations other than lower extremity long bones. Questions/purposes We determined the pain relief and complication rates after radiofrequency ablation of osteoid osteomas presenting in atypical locations and followed patients to assess possible recurrence or late complications. Patients and MethodsWe retrospectively reviewed 21 patients with osteoid osteomas in unusual locations (eg, hip, radioulnar joint, and proximal phalanx) in whom we used radiofrequency ablation. Postoperative activities were not restricted for any of the patients. We assessed the time for patients to become symptom free, their activity status, and possible recurrence or complications. The minimum clinical followup was 12 months (mean, 27.8 months; range, 12-37 months).

“…In recent years, the use of computed tomography (CT)-guided percutaneous radiofrequency thermoablation (PRT) has been reported with good results and this has been shown to have similar recurrence rates to open surgery but with fewer complications and shorter periods of hospital stay [7,8]. Several studies have been published describing the outcome and side effects of RFA.…”

Purpose This study aimed to determine the mid-and longterm success and complication rates of radiofrequency ablation (RFA) in treatment of osteoid osteoma (OO). Furthermore we were interested in the value of bone biopsy when using a core-drill before the radiofrequency ablation. Methods We retrospectively analysed data of 33 patients (33 osteoid osteomas, 22 males, 11 females) who underwent computed-tomography (CT) guided radiofrequency ablation between 1998 and 2005. The patients had a mean age of 20 years (range, five to 50 years). They were monitored for a mean follow-up of 92 months (range, 60-121 months). Results Lesions were located as follows: 11 cases in the proximal femur, five in the femoral shaft, six in the tibia, one in the calcaneus, two in the metatarsals (second and fourth metatarsals), one in the os cuneiforme mediale, six in the humeral and one in the ulnar shaft. Within the presented time frame 32 of 33 patients were successfully treated and had no more complaints. In one of 33 patients relapse occurred after 28 months and RFA was repeated. There were no complications associated with the procedure. Biopsy obtained prior to thermocoagulation with the help of a core-drill was able to prove diagnosis in all patients (100%). Conclusions These results indicate that the presented technique of CT guided RFA combined with the use of a core-drill for biopsy prior to RFA treatment is a highly effective, efficient, minimally invasive and safe method for the treatment of OO, yielding a success rate of 97% combined with a 100% histological verification of the diagnosis after a minimum follow-up period of five years.

To study the effects of the control temperature, ablation time, and the background tissue surrounding the tumor on the size of the ablation zone on radiofrequency ablation (RFA) of osteoid osteoma (OO). Finite element models of non‐cooled temperature‐controlled RFA of typical OOs were developed to determine the resulting ablation radius at control temperatures of 70, 80, and 90°C. Three different geometries were used, mimicking common cases of OO. The ablation radius was obtained by using the Arrhenius equation to determine cell viability. Ablation radii were larger for higher temperatures and also increased with time. All geometries and control temperatures tested had ablation radii larger than the tumor. The ablation radius developed rapidly in the first few minutes for all geometries and control temperatures tested, developing slowly towards the end of the ablation. Resistive heating and the temperature distribution showed differences depending on background tissue properties, resulting in differences in the ablation radius on each geometry. The ablation radius has a clear dependency not only on the properties of the tumor but also on the background tissue. Lower background tissue's electrical conductivity and blood perfusion rates seem to result in larger ablation zones. The differences observed between the different geometries suggest the need for patient‐specific planning, as the anatomical variations could cause significantly different outcomes where models like the one here presented could help to guarantee safe and successful tumor ablations.
