Abstract

Objectives: Osteoid osteoma (OO) is one of the most common benign bone tumors and can occur in various skeletal structures. It often presents with symptoms, such as nocturnal pain, which may mimic constitutional conditions, and it is characterized by a distinct radiological appearance that allows for easy differentiation from other lesions. Over the past decade, numerous studies have evaluated the efficacy of both surgical and radiological interventions for treating OO. While several treatment methods are available, each carries distinct advantages and disadvantages. This study aims to report the outcomes of surgical resection for ocular (OO) lesions. Methods: A total of 29 patients were enrolled in this study. Of these, 14 patients chose surgical resection as their primary treatment, while 15 patients opted for radiofrequency (RF) ablation. Three patients who exhibited a lack of response to RF ablation subsequently underwent surgical resection, bringing the total number of patients in the surgery group to 17. This study specifically focused on lesions located in the peritrochanteric region. For lesions that recurred at the same site, whether due to recurrence or lack of response to initial treatment, the same treatment modality used in the first instance was applied. Results: Among the 17 individuals who initially underwent surgical resection, 11 had extracapsular lesions, and 6 had intracapsular lesions. All patients who underwent surgical resection became symptom-free, and no complications were observed during the procedure. Furthermore, all cases that received surgical resection were confirmed through pathological assessment. Additionally, three patients with extracapsular lesions had previously been treated with RF thermoablation but had not fully recovered from their symptoms, necessitating surgical resection. Conclusion: Based on the results, although RF is the first choice of treatment for OO, surgical resection could be a vital and safe option for peritrochanteric OO.
