Spinal Fusion
Alternate Names : Anterior Spinal Fusion, Arthrodesis, Harrington Rod Insertion, Luque Rod Insertion, Posterior Spinal Fusion
Definition
Spinal fusion involves surgical treatment of abnormalities in the spine bones (vertebrae), such as abnormal curvatures (scoliosis or kyphosis) or injuries (fractures). The surgery stabilizes the back by fusing certain vertebrae together with bone grafts or metal rods.
The most common spinal area involved is the lower (lumbar) spine, but upper (cervical) spine fusion can also be performed. This surgery can also be used to treat arthritis or infection.

Overview & Description
While the patient is under general anesthesia (unconscious and pain-free), an incision is made over the area of the spine that will be treated.
The lower spinal vertebrae are often repaired through an incision directly over the spine -- this is called the posterior lumbar approach. The upper spinal vertebrae are often repaired through an incision in the front or side of the neck (anterior cervical spine). The middle spinal vertebrae are sometimes repaired through an incision made in the chest and abdomen (anterior thoracic spine).
Any area of the spine can be repaired from the front side or the back, depending on the disease and surgeon's preferences.
The abnormal or injured vertebrae are repaired and stabilized with bone grafts, metal rods, or both.
