Posterior Lumbar Interbody Fusion (PLIF)

Posterior lumbar interbody fusion (PLIF) is a specific form of spinal fusion surgery. Like all spinal fusion surgeries, this procedure involves inserting a bone graft and/or spinal implant (such as a cage) directly into the disc space. The hope is that this will cause the body to respond by growing bone between the two vertebrae in question, thereby eliminating motion and promoting stability. This enhanced stability will then ease the pain and other symptoms caused by degenerative disc conditions such as spondylolisthesis.

How is it Performed?

The term "posterior" included in the name of this procedure means that the surgery is performed from the back. Therefore, the surgeon will approach the spine through a three- to six-inch long incision in the back. The surgeon will then remove disc material in order to clear the area for the insertion of the bone graft or spinal implant, which will then promote bone growth between the two vertebrae.

What are the Risks?

As with most open back surgeries, there are some risks involved with a posterior lumbar interbody fusion (PLIF). These can include:

• A larger bone graft or implant can be inserted from an anterior (front) approach
• Not as much disc material can be cleared when approaching the spine from the posterior, rather than the anterior
• There may be a failure in fusion, causing new symptoms or the continuation of existing ones
• And more

Minimally Invasive Alternatives

PLIF surgeries also come with the many of the other negative aspects of traditional spine surgery, such as a large incision and lengthy recovery times. If conservative treatments have failed to ease the pain and other symptoms a degenerative spine condition is causing you, and you're concerned about the risks of fusion surgery, contact Laser Spine Institute today. Our orthopedic experts perform a variety of minimally invasive, endoscopic procedures that are safe, effective alternatives to open back surgery, and that can help you rediscover your life without back and neck pain.
