The Procedure

Posterolateral Fusion in DallasPosterolateral lumbar fusion is one of the oldest and simplest ways to fuse bone. It involves exposing the bony surfaces of the vertebrae that need to be fused, drilling away the hard, outer layer, or cortex ,of the bone, and then packing graft material, consisting of the patient’s own bone, cadaver bone, or synthetic bone, upon the  exposed bony surfaces.

Posterolateral lumbar fusion can be a stand-alone procedure, in which case it is called a noninstrumented fusion.  Most of the time, however,   it is performed in conjunction along with procedures such as  InstrumentationAnterior Lumbar Interbody Fusion (ALIF)Posterior Lumbar Interbody Fusion (PLIF), or Extreme Lateral Interbody Fusion (XLIF).
