What Is Spinal Fusion?

From WebMD

 

Spinal fusion is surgery to join two or more vertebrae into one single structure. The goal is to stop movement between the two bones and prevent back pain. Once they’re fused, they no longer move like they used to. This keeps you from stretching nearby nerves, ligaments, and muscles that may have caused discomfort.

Spinal fusion involves techniques designed to mimic the normal healing process of broken bones. During spinal fusion, your surgeon places bone or a bonelike material within the space between two spinal vertebrae. Metal plates, screws and rods may be used to hold the vertebrae together, so they can heal into one solid unit. Read more

What is Spinal Stenosis?

From WebMD

Cervical Spinal Stenosis

Spinal stenosis is a condition, mostly in adults 50 and older, in which your spinal canal starts to narrow. This can cause pain and other problems.

Your spine is made up of a series of connected bones (or “vertebrae”) and shock-absorbing discs. It protects your spinal cord, a key part of the central nervous system that connects the brain to the body. The cord rests in the canal formed by your vertebrae.

For most people, the stenosis results from changes because of arthritis. The spinal canal may narrow. The open spaces between the vertebrae may start to get smaller. The tightness can pinch the spinal cord or the nerves around it, causing pain, tingling, or numbness in your legs, arms, or torso. Read more

How The Spinal Cord Works

Article shared from ChristopherReeve.org

What is the central nervous system?

The central nervous system (CNS) controls most functions of the body and mind. It consists of two parts: the brain and the spinal cord.

The brain is the center of our thoughts, the interpreter of our external environment, and the origin of control over body movement. Like a central computer, it interprets information from our eyes (sight), ears (sound), nose (smell), tongue (taste), and skin (touch), as well as from internal organs such as the stomach.

What Are Spinal Disk Problems?

Anybody who has experienced a damaged spinal disk understands how painful it is. Every movement seems to make it worse. This pain is a warning signal that you should heed. If you take appropriate action, the discomfort usually stops, and the problem can be corrected.

Lumbar Spine Surgery

Article Featured on Spine Health

Lumbar surgery refers to any type of surgery in the lumbar spine, or lower back, between one or more of the L1-S1 levels. There are two general types of lumbar spine surgery that comprise the most common surgical procedures for the lower back:

Lumbar Decompression

The goal of a decompression surgery is usually to relieve pain caused by nerve root pinching. There are two common causes of lumbar nerve root pressure: from a lumbar herniated disc or lumbar spinal stenosis.

This type of pain is usually referred to as a radiculopathy, or sciatica.

A decompression surgery involves removing a small portion of the bone over the nerve root and/or disc material from under the nerve root to relieve pinching of the nerve and provide more room for the nerve to heal. The most common types of decompression surgery are microdiscectomy and laminectomy.

There are also a few alternatives available to the above two standard procedures, such as an X-STOP which is a possible option instead of a laminectomy for lumbar spinal stenosis.

Lumbar Fusion

The goal of a lumbar fusion is to stop the pain at a painful motion segment in the lower back. Most commonly, this type of surgery is performed for pain and disability caused by lumbar degenerative disc disease or a spondylolisthesis.

A spinal fusion surgery involves using a bone graft to stop the motion at a painful vertebral segment, which in turn should decrease pain generated from the joint. Spine surgery instrumentation (medical devices), bone graft procedures, and a bone stimulator are sometimes used along with spinal fusion.

There are also many surgical approaches to performing spinal fusion, such as ALIF, PLIF, XLIF, TLIF, posterolateral gutter fusion, anterior/posterior fusion, and certain minimally invasive approaches.

In addition to the above conditions, decompression and/or spinal fusion may be performed to address other types of lumbar spine pathologies, such as infection or tumors.

Lumbar Spine Surgery Alternatives

In addition to the traditional one-level fusion or decompression surgery that is done for lumbar degenerative disc disease or spinal stenosis, respectively, there are a number of surgical alternatives available. Several of the most common ones include:

Artificial Disc Replacement

Artificial disc technology can be used in specific cases of lumbar degenerative disc disease.

Motion Preservation Technologies

It should be known that while spinal fusion has been a classical treatment for ongoing pain and disability from the lumbar spine, alternatives to fusion do exist for posterior conditions (problems in the back of the lumbar spine) such as spinal stenosis. Inserting an interspinous process spacer, such as the X-STOP device, can actually preserve motion as opposed to stopping it via fusion.

Vertebral Augmentation

A surgery called vertebral augmentation may be done to treat pathological fractures from tumors or osteoporosis.

Multilevel Lumbar Fusion

Lumbar spine fusion surgery for symptomatic degenerative disc disease is typically done on one level of the spine (most commonly toward the bottom of the spine, at L5-S1 or L4-L5). In certain cases it may be done on two levels, and only very rarely would it be considered on 3 or more levels. Multilevel spine fusion may be indicated in cases of scoliosis.

There are only two things that surgery can do. Surgery can decompress a nerve root or it can stabilize a painful motion segment. So we have to identify a nerve root that’s pinched or we have to identify a painful motion segment. And if we can do that, that would make you a candidate for surgery. Just having pain and having failed conservative treatment is not an indication for surgery if there is no pathological cause of the pain – it doesn’t mean there’s not pain, but we have to identify the cause of pain in order to be able to correct it. The only thing surgery can do is actually correct an anatomical defect, so we have to be able to identify it.

Bone Grafts in Spine Surgery

Article Featured on AAOS

Spinal fusion is one of the most common surgeries done in the neck or back. The basic idea is to fuse together painful bones in the spine so that they heal into a single, solid bone. In order for bones to fuse or heal together, additional bone is needed. This additional bone is called a bone graft.

There are many bone graft options today. They are often combined together. The graft that is best for your problem will depend upon which section of your spine needs to be fused, your age, and your general health.
