Figure 1: Case 1 (A) osteoid osteoma of glenoid cavity; (B) radiofrequency electrode placement Case 2: (A) osteoid osteoma of posterior element of vertebra; (B) radiofrequency electrode treatment in prone position; (C) Treated sclerosed lesion Case 3: Nidus in neck of left femur posteriorly (A) Entry from opposite cortex (B) to avoid neurovascular injury. Case 4: Intramedullary nidus of tibia without sclerosis (A) offers no resistance while drilling. Overshooting off-centering at first attempt of electrode positioning (B) Case 5: Significant sclerosis in a tibial osteoid osteoma (A) Difficult navigation during access of this lesion resulted in breakage of drill beat (B)
