A laminectomy is performed at the area between the pedicles of the affected vertebra. The laminectomy is performed through a small midline incision centered over the affected level. Alternatively, it can be performed using tubular or expendable retractors. To illustrate the procedure we will here use a small midline incision.
Based on preoperative planning, the amount of lamina to be removed to achieve enough decompression can be determined beforehand.
