Spinal Fusion PLIF

What Is Posterior Lumbar Interbody Fusion?

This complex surgery stabilizes the lower spine by fusing two or more lumbar vertebrae. The posterior lumbar interbody fusion (PLIF) procedure is used to treat intractable back or leg pain resulting from certain degenerative conditions. This type of spinal fusion requires the neurosurgeon to reach the vertebrae from the back (posterior) of the patient.

What Conditions Does Posterior Lumbar Interbody Fusion Treat?

Back or leg pain caused by certain conditions might be greatly improved by Posterior Lumbar Interbody Fusion:

PLIF may be recommended for chronic, severe lower back pain that is not improved by more conservative treatments such as medications, back braces or physical therapy.

There are a few different types of spinal fusion grafts depending on the condition that needs to be treated. These grafts can include:

  • Autograft fusion – a piece of the patient’s own bone, typically taken from the hip, is used.
  • Allograft fusion – a piece of cadaver bone is used for the bone graft.
  • Synthetic (artificial) graft fusion – manufactured materials and natural bone are used.

A number of innovations have made spinal fusion surgeries more likely to have a successful outcome for the patient than in the past. Medical advancements such as newer instrumentation, improved procedures, an increased knowledge base of the spine’s mechanics, better surgeon training and advanced diagnostics with premier medical imaging techniques.
