Spinal Anatomy

4
Degenerative Disc Disease (DDD)
DDD is a slow deterioration of discs located between vertebrae.
Since these discs act as a shock absorber between each vertebra, the reduction or loss of disc height can cause pain.
The degenerated disc is not getting enough nutrients and will not be able to repair itself once injured.

5
Degenerative Disc Disease (DDD)
The inner core of a disc, or the nucleus pulposus, is very soft and can cause severe leg pain if it comes into contact with the surrounding nerves.
If the outer portion, or annulusfibrosus, tears, the nucleus pulposus can herniate and can cause back pain.

6
Spondylolisthesis
Occurs when one vertebra slips forward in relation to an adjacent vertebra, usually in the lumbar spine.
Symptoms include pain in the low back, thighs and/or legs, muscle spasms, weakness, and/or tight hamstring muscles.
Some people are symptom free and find the disorder exists when revealed on an x-ray.

7
Spondylolisthesis
May result from the physical stress placed on the spine, improper lifting of heavy items, weightlifting, football, gymnastics, trauma, and general wear and tear.
As the vertebral components degenerate, the spine’s integrity is compromised. Pain is the primary symptom associated with spondylolisthesis.

8
Spondylolisthesis
Depending on how far the vertebra has slipped, doctors label spondylolisthesis in four grades, I (one) being the least amount of slippage, all the way up to IV (four), which is the most slippage.
Not all cases of spondylolisthesis require surgery.

9
Spinal Stenosis
Spinal stenosis is the narrowing of the bony ring that surrounds the spinal cord. Some specific conditions that can cause spinal stenosis include:
Bone spurs
Disc degeneration
Arthritis
This condition is most common in elderly people, who have had years of wear-and-tear on their intervertebral discs.

10
Spinal Stenosis
This degeneration of the spine can cause pain in the back as well as in other parts of the body.
The narrowing of the spinal canal can lead to reduction in oxygen and blood to the spinal cord, and can cause numbness in pain from irritated nerves and lack of blood flowing through the spine.

11
Discogenic Issues
Discogenic Pain
Caused by a damaged disc. While this pain can be felt directly in the lower back, it may also be felt outside of the area of the damaged disc, such as in the buttocks or upper thighs.
Specific movements that put stress on this damaged disc can worsen the pain. The pain may radiate to different areas of the body via the irritated nerve roots.

12
Discogenic Issues
Pinched Nerve
Also known as radiculopathy, or sciatica, a pinched nerve in the spine occurs when something rubs or presses on a nerve to cause irritation. This irritation can lead to numbness in a specific area of the body.

13
Discogenic Issues
Pinched Nerve
Sometimes it is difficult to identify the source of pain. For example, you may experience pain in your buttocks, leg or foot which is directly associated with an irritation in your lower back. This pinched nerve can cause weakness in muscles and loss of reflexes in the location of your pain.
Herniated discs and collapsed discs are the most common causes of a pinched nerve. Less common causes include bone spurs, fractures or tumors.

14
Discogenic Issues
Bulging or Herniated Disc
Definition: a disc that is protruding beyond its normal location between vertebrae.
Bulging discs are somewhat common.
Can occur in the aging process of an adult.
Can occur with the degeneration of an intervertebral disc.

15
Discogenic Issues
Bulging or Herniated Disc
Herniated Disc occurs when the jelly-like center (nucleus) of the intervertebral disc ruptures and tears.
Only becomes cause for alarm when it compresses a nerve root.
Causes material to be pushed outside of the disc, causing pain.
Pressure on the spinal cord and nerve roots cause pain, weakness, and/or numbness to certain areas of the body, similar to a pinched nerve.

16
Spinal Fusion
Spinal fusion is a surgical procedure in which two or more of the vertebrae in the spine are united together so that motion no longer occurs between them.
The diseased disc is removed and replaced with supplementary bone tissue. Ideally, this bone tissue allows the adjacent vertebrae to fuse together, thus immobilizing the vertebrae.
Various hardware is often used to hold the vertebrae together while this fusion process occurs.
Spinal fusion can restore stability, correct alignment & reduces pain.

Traditional Fusion

18
Interbody Fusion Approaches

19
Posterior Lumbar Interbody (PLIF) Fusion
Direct decompression
Exposes dural elements
Retraction risks to nerves

20
Anterior Lumbar Interbody (ALIF) Fusion
Excellent visualization of disc space
Avoids dural sac
Approach risks to organs and vascular structures
No decompression option

21
Transforaminal Lumbar Interbody (TLIF) Fusion
Avoids dural sac
Direct decompression possible
Potential nerve irritation

22
Axial Lumbar Interbody (AxiaLIF) Fusion
Preservation of Native Tissues & Muscles
May Preserve Annulus
Robust Anterior & Posterior Fixation
Dynamic Decompression via Distraction

23
AxiaLIF Pre-Sacral Fusion
Unique Features
Only interbody graft option where:
No muscle is dissected
No ligaments are cut
The disc annulus is preserved

FAQs
What are the risks of this procedure?
As with any surgical procedure, there are risks. However, when compared to other fusion procedures which enter your spine through the abdomen (ALIF) or directly through the back (PLIF), AxiaLIF has fewer risks. There is no need to bypass vital nerves, arteries or muscle, and no need to strip back muscles from your spine to get to the diseased disc. This sparing of soft tissue and muscle provides fewer risks and complications after your surgery.
How long will it take to get back to work?
Many people can return to work in as little as 15 days. However, individual results may vary.

30
FAQs
How long will it take to return to my daily activities?
Your doctor will likely recommend that you restrict your activity immediately after your AxiaLIF surgery. After about two weeks, most AxiaLIF patients will be able to resume normal daily activities. However, results do vary from patient to patient.
How long will I have to stay in the hospital after surgery?
For a traditional fusion surgery, the average length of stay is four days*. AxiaLIF length of stay is typically one to two days. Some AxiaLIF procedures are performed on an outpatient basis and patients go home on the day of surgery.

FAQs
How much pain should I expect after the procedure is performed?
The amount of pain that a patient will experience immediately following the procedure can vary. This discomfort will tend to diminish over a short period of time.
The AxiaLIF procedure results in less soft tissue disruption than other fusion approaches which means that post-op pain is often less intense for AxiaLIF patients. Please keep in mind that any surgery, even minimally invasive, involves some pain and recovery time. AxiaLIF patients tend to show significant improvement in back pain as a result of their surgery.

32
FAQs
How many scars will I have from this procedure? How big will they be?
The AxiaLIF portion of the procedure creates only one scar which is about one-inch long and located next to your tailbone. Depending upon your condition, you may require further stabilization in your spine that would result in additional incisions/scars.
