Abstract
Objectives : Osteoid osteoma (OO) is one of the most common benign tumors that can appear in different portions of skeletal structures. It can mimic constitutional symptoms like nocturnal pain and has a specific radiologic feature, and thus, can be differentiated from other lesions with ease. Various studies have been performed in the past decade to assess the efficacy of surgical or radiological procedures to eliminate the tumor. There are some methods for treatment which have advantages and disadvantages. In this study, we tried to report the result of surgical resection for OO lesions.
Methods: We enrolled 29 patients in our study; 14 patients preferred resection as their primary intervention, the other 15 favored radiofrequency (RF) ablation. Three patients who had lake response to RF were treated with surgical resection, so overall population of the surgery group was 17. Lesions located in the peritrochanteric region have been chosen to be investigated in this study. lesions which relapsed in the same spot, whether recurrent or unresponsive to initial treatment, were approached with the same procedure they were treated first hand.
Results: Among the 17 individuals, who underwent surgical resection first, 11 had extracapsular lesions and 6 had intracapsular lesions. All patients treated with surgical resection became symptom free, and there were no complications in this procedure. Moreover, all cases treated with surgical resection were confirmed with pathologic assessment. In addition, 3 cases of extracapsular lesions had previously been treated with RF thermoablation and had not fully recovered from their symptoms; hence, they underwent surgical resection.
Conclusion: Our study shows that although RF is the first choice of treatment for OO, surgical resection could be the vital and safe option for peritrochanteric OO.
