Lumbar Spinal Fusion Surgery For Spondylolisthesis
For Back Pain Relief
Lumbar fusion surgery is a procedure performed to immobilize two adjacent vertebrae or a number of vertebrae in the lower back part of the spine. It may be performed to relieve back pain, stabilize the spine, or to restore a more normal shape to the spine.
Fusion refers to the growth of new bone between two (or more) adjacent vertebral bodies. Graft materials help to stimulate and promote this growth, acting as scaffolding across the disc space from one vertebral body to the next, thereby fusing the two vertebrae and immobilizing the spine at that segment.
A variety of bone growth-promoting materials are available to help accelerate the fusion process. In the past, bone harvested from another portion of the patient’s body was used. With the advances in technology over the past decade, there are many products which are now used to decrease the need of using the patient’s own bone.
Often surgical hardware is implanted into the spine to help immobilize the segments while the bone is fusing which can take six months to a year to occur.
