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

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.
