Posterolateral Fusion

Posterolateral fusion is a form of spinal surgery in which the surgeon approaches the spine from the back and performs spinal fusion. Like other fusion procedures, this surgery’s aim is to increase spinal stability and decrease the symptoms associated with a degenerative spine condition such as degenerative disc disease, spinal stenosis, spondylolisthesis, and others. Affected spinal vertebrae are permanently fused in this procedure using metal rods and screws.

The Procedure

Here are the steps involved in a posterolateral fusion:

• A bone substitute or harvested bone is acquired, often requiring additional surgery.
• The surgeon creates a 3- to 6-inch incision in the middle of the lower back.
• Soft tissue is excised in order to allow access to the affected area.
• The bone graft is implanted, and soft tissue is replaced.
• Metal screws and rods are inserted to provide stability while the bone graft grows and the vertebrae fuse together.

Risks, Downsides, and Alternatives

As with any open back surgery, posterolateral fusion carries a number of risks and downsides, such as an increased chance of infection, rejection of the hardware, scarring, and a lengthy recovery.
