Posterolateral Interspinal Fusion with Pedicle Screws
The patient was properly identified by anesthesia, brought to the operating room, and positioned supine on the cart. General anesthetic was delivered and he was intubated. He was log-rolled onto the Wilson frame. All pressure points were padded. Antibiotics were given. The back was prepped and draped in the usual fashion. A midline incision was made over what was thought to be the L4/L5 level. Once the lumbar fascia was identified, dissection was carried down onto the appropriate level spinous process. A hemostat was placed between the spinous processes of L4 and L5 and its position was confirmed on a lateral radiograph which included the sacrum. Dissection was then carried down the lamina of L4 and L5 bilaterally to the level of the facet joints.
