When pain from spondylolisthesis does not diminish with conventional treatment methods, such as physical therapy or a back brace, spinal fusion surgery may be your best option. Some cases of isthmic and degenerative spondylolisthesis that do not respond to nonsurgical forms of treatment respond well to spinal fusion surgery, which can help reduce your pain and other symptoms. Isthmic spondylolisthesis. occurs when a vertebra slips out of position due to spondylolysis—a condition that causes spinal fractures. Degenerative spondylolisthesis occurs when one or more spinal bones move out of position as they weaken with age.There are several types of spinal fusion surgery available to treat spondylolisthesis. The aim of these procedures is to stabilize your spine and reduce pain.
During this type of spinal fusion surgery, your surgeon will approach the affected area from the back. A piece of your pelvic bone will be removed and placed between your slipped vertebrae, allowing them to fuse to the spine and form a stable piece of bone.
Posterior and Transforaminal Lumbar Interbody Fusion
This type of spinal fusion surgery involves approaching the affected area through the lower back, although the surface area is limited when using this technique. Posterior transforaminal fusion is best used to treat localized spondylolisthesis located in the lower back.
Anterior Lumbar Interbody Fusion
This type of spine surgery involves approaching the affected area of your spine through the abdomen, which offers a larger surface area for the procedure. Anterior fusion surgery is usually preferred for treating spinal deformities caused by is thmic spondylolisthesis. Like posterior spinal fusion surgery, anterior fusion involves placing a piece of pelvic bone between spinal bones and allowing them to fuse to your spine.
