What does it mean to have posterior lumbar interbody fusion?

PLIF procedure. A posterior lumbar interbody fusion (plif) is a procedure in which an unstable lumbar segment is fused in conjunction with a decompressive laminectomy. As part of the fusion, bone grafting (often with a cage device) is placed into the disc space to allow for fusion, but also helps re-align the segment. It can be performed with open and minimal invasive techniques.
A common procedure . There are several common approaches for fusing the lumbar spine. A posterior approach involves exposing the posterior elements of the lumbar spine, removing the pathologic disc, placing a spacer in the disc space with a bone graft and stabilizing the level with instrumentation. It is performed to fuse the spine thru the disc space. Check out spine health.Com.
Fusion from the back. It is a type of fusion surgery. Two bones are made to grown together as one. The disk between the two bone (interbody or between the two bodies) is removed from the back side (posterior) and replaced with bone or another spacer (usually metal or plastic) along with bone or a bone substitute. To get to the disk, the dura (sac of nerves to and from legs) is moved.
