title: Osteoid osteoma of the glenoid: Arthroscopic treatment.
abstract: Osteoid osteoma is a benign tumor that is rarely found in the scapula. We report a clinical case involving a 36-year-old female patient who suffered from progressive pain in her right shoulder for 1 year. This patient was initially diagnosed with impingement syndrome and was treated unsuccessfully with medication and physical therapy for approximately 2 months. Based on imaging exams, a juxta-articular osteoid osteoma of the glenoid was identified. The patient underwent a shoulder arthroscopy that included tumor removal and treatment of the resulting chondral lesion. At 6-, 12- and 36-month assessments, the patient was asymptomatic, with a normal range of motion and experienced a pain intensity corresponding to 0 points on the Visual Analog Scale (VAS) and 35 points on the University of California, Los Angeles (UCLA) Scale. A postoperative MRI indicated the absence of any residual tumor tissue or inflammatory signs. We believe that the approach described in this paper allows juxta-articular osteoid osteomas to be accessed in a minimally invasive manner and permits not only adequate resection but also the treatment of chondral lesions that could remain after tumor resection.
