Table 1 The technical tips and pearls of computed tomography-guided resection

From: Osteoid osteoma of the acetabulum successfully treated with computed tomography-guided resection and ablation using a standard electrosurgical generator: a case report

Number Step Tips
1 Approach Preoperative planning to assess the optimal approach to the nidus.
It should be the shortest route to the bone surface and must avoid the neurovascular bundle.
2 Position Patient must be positioned to allow easy access to the bone.
3 Incision Blunt dissection should be performed to the bone to protect nerves and vessels. A small incision may be needed if an important structure is nearby.
4 Drilling Drill hole perpendicular to the bone surface. Contralateral cortex should not be compromised to allow through ablation after resection of the nidus.
5 Fluoroscopy Computed tomography usage should be minimized. Fluoroscopy is utilized to check the positioning of the guide pin and drill.
6 Diagnosis The specimen inside the cannulated drill is important because it can be used to make a histological diagnosis.
7 Ablation Standard electrosurgical generator is placed at the site of the lesion for 60 seconds under 15 W to ablate the possible remaining tumor cells.
