This surgical approach involves placing bone graft in the posterolateral portion of the spine area just outside the spine.
Posterolateral gutter spine fusion surgery.
In an attempt to improve the results of fusion surgery fusion of the disc has been performed to directly address the most common source of pain.
In posterolateral gutter fusion surgery.
First bone graft is obtained from the pelvis the iliac crest although some form of bone graft substitute may also be.
Unlike the posterolateral gutter fusion the plif achieves spinal fusion by inserting bone graft and possibly instrumentation.
There are several different types of spinal fusion surgery.
The back muscles hold the graft in place until it fuses with the vertebrae.
Bone graft is taken from the pelvis and laid out in the posterolateral portion of the spine that is to be fused.
In a posterolateral gutter fusion the surgical approach to the spine is from the back through a midline incision that is approximately three inches to six inches long.
As the harvested bone graft grows and adheres to the transverse processes such as between l4 and l5 lumbar segment 4 and lumbar segment 5 the spinal fusion is achieved and motion at that segment is stopped.
After a posterolateral gutter spine fusion the body engages in a natural process to repair itself which usually means growing bone.
The posterolateral gutter fusion is considered by many surgeons as the tried and true method of spinal fusion.
In spinal fusion surgery the doctor implants either a device or bone material to help re stabilize the spine.
This article focuses on posterolateral lumbar fusion the most common type of spinal fusion and discusses only the surgical component of the procedure.
In a posterolateral gutter fusion procedure the spine is approached from the back.
Any type of spine fusion joins together or fuses a spinal segment to eliminate the motion at that level of the spine.
Just like in interbody fusion arthritic bone restricting and or compressing the spinal column and nerves may be removed with laminectomy laminotomy foraminotomy facetectomy or a combination see figure 4.
One of the main differences between these two approaches is where the bone graft is laid in the spine to form the fusion.
The device is often a type of cage that mimics the build of a damaged disc.
A lumbar posterolateral gutter fusion is done in the lower back at l1 through l2 through l5 through s1 at the bottom of the spine.
An incision is made at the midline of the back and bone graft is placed underneath the large back muscles that attach to the transverse processes of the affected vertebrae.
Posterior fusion the posterior structures of contiguous vertebrae are fused either the laminae facets transverse processes spinous processes or a combination of them.
In general there are two main approaches to spinal fusion a surgery designed to stop low back pain caused by painful motion of the vertebrae.
