The patient is given general anesthesia. The surgeon makes an incision in the left side of the patient to gain access to the spinal column.
Removal of Discs
The surgeon removes the discs above and below the diseased or damaged vertebrae. Any fragments of damaged vertebra are also removed. The surgeon clears the bone surface and prepares it for receiving the bone graft.
Correction of Curvature
The surgeon inserts bolts in the upper and lower vertebrae. With the help of these bolts and other surgical instruments, the vertebral space is opened and the curvature of the spinal cord is corrected.
Insertion of Bone Graft
Once the space is open, the bone graft or substitute of bone graft is implanted in the space. The vertebral space is then closed to hold the bone graft firmly in its place.
Insertion of Zplate
A metal plate known as Zplate is put between the upper and lower vertebrae. This plate bridges the upper and lower vertebrae. Screws and nuts are added to keep the Zplate in its right place.
The procedure ends when the surgeon closes the incision with the help of stitches. The wound is cleaned and a medical bandage is applied over it.During the process of healing, the bone graft will knit with the upper and lower vertebrae to form a single solid bone fragment called a fusion.
