What is Cervical Disc Replacement?

Your cervical spine is made up of the seven bones, called cervical vertebrae, stacked on top of each other in your neck area. The natural cervical intervertebral disc is an amazing mechanical structure from an engineering perspective. It has the ability to absorb a large compressive load while still providing an impressive range of motion between the bones in the neck.

The Cervical disc replacement process involves the insertion of an artificial cervical disc is a device inserted between two vertebrae in the neck to replace a damaged disc. The intention of the artificial disc is to preserve motion of the natural disc.


Reasons for the procedure

There are a number of important factors in considering cervical disc replacement surgery. It is important to remember that a disc replacement is a motion-preservation procedure and not a motion-creation procedure.

Loss of space between your cervical vertebrae from cervical disk degeneration, or wear and tear, is common. Cervical disks begin to collapse and bulge with age; this happens to most people by age 60. Some people have more cervical disk degeneration symptoms than others.

The symptoms may include:

  • Neck pain
  • Neck stiffness
  • Headache
  • Pain that travels down into your shoulders or into your arms
  • Weakness of your shoulders, arms, hands, or legs
  • "Pins and needles" or numbness in your arms


Risks of the procedure

Disk replacement surgery is a safe procedure, but all surgeries carry some inherant risks. These will be explained before the procedure.

As with all newer technologies, one important consideration with this procedure is that long-term studies and follow-up are needed to fully understand the potential risks and benefits of cervical disc replacement. You should discuss the risks and benefits of disk replacement surgery compared with more traditional types of cervical spine surgery with your surgeon.

Some potential risks of cervical spine surgery include:

  • Reactions to the anesthesia
  • Bleeding
  • Infection
  • Nerve injury
  • Spinal fluid leak
  • Voice change
  • Stroke
  • Difficulty breathing
  • Difficulty swallowing
  • Failure to relieve symptoms
  • Broken or loosened artificial disk
  • Need for further surgery

There may be other risks, depending on your specific medical condition. Be sure to discuss any concerns with your surgeon before the procedure.


What is a Kyphoplasty?

Kyphoplasty is a procedure in which bone cement is injected through a small hole in the skin into a fractured vertebra with the goal of relieving back pain caused by a spinal fracture, to stabilize the bone, and to restore some or all of the lost vertebral body height due to the compression fracture.

Reasons for Kyphoplasty Surgery

The vertebrae are a series of bones that make up the spine. If one suffers a fracture, it can put pressure on surrounding nerves. This can cause intense pain and disability. These bones could be repaired kyphoplasty procedure. A balloon is used to create a cavity in the bone and this is used to inject bone cement. The procedure is designed to relieve pain, but can also improve spinal deformities from the fractures.

Other treatment for vertebral fracture may include nonsurgical treatments (like bed rest, bracing, and pain medicines).


Risks and Complications of Kyphoplasty

Complications are rare, but no procedure is completely free of risk. If you are planning to have a vertebroplasty or kyphoplasty, your doctor will review a list of possible complications which may include:

  • Nerve damage or a spinal cord injury from malpositioned instruments placed in the back
  • Nerve injury or spinal cord compression from leaking of the PMMA into veins or epidural space
  • Allergic reaction to the solution used to see the balloon on the X-ray image as it inflates



What is Minimally Invasive Cervical Fusion?

A minimally invasive cervical fusion procedure is the permanent fusion of the lower three cervical vertebrae (vertebrae in the neck). During this procedure, the intervertebral discs at C5-C6 and C6-C7 will be removed. In their places, bone grafts are inserted and secured in place. Over time, a solid segment of bone will form between these segments in the lower portion of the cervical spine.


Reasons for the procedure

If you have been suffering from chronic neck pain and you have tried several types of non-surgical treatment options, as recommended by your doctor, but these have not worked; as you consider your surgical options, we invite you to consider minimally invasive cervical spine surgery.

Minimally invasive cervical spine surgery is a procedure that treats spinal conditions in the neck and upper back. It requires only a small incision for targeted access to the spine and does not require bulky hardware or muscle disruption.

Some of the most common conditions that would lead considering this procedure include herniated discs, collapsed discs and bone spurs, or a degenerative spine condition or injury that is causing compression of the cervical spinal nerve roots or the spinal cord.


Advantages of Minimally Invasive Cervical Fusion

Our minimally invasive cervical fusion procedure is a safer and more effective alternative to traditional open neck surgery. Our minimally invasive procedures are performed through a small incision in the neck or back, about 1-inch in length. Thanks to recent advanced medical technology, our surgeons to access the spine without altering the surrounding muscles and soft tissue. This allows for minimal scarring and shorter recovery time.

Because this minimally invasive surgery is performed through the front of the neck, instead of the back, it offers many benefits including:

  • Access to nearly the entire cervical section of the spine through an uncomplicated pathway that minimizes trauma to surrounding areas
  • Generally less post-operative pain, due to a smaller incision and less movement of associated tissue, muscles and nerves
  • Minimally invasive surgery typically means less blood loss, faster pain relief and shortened post-operative recovery times, so patients can get back to their daily life and work sooner


What is Minimally Invasive Decompression Surgery?

The process involves a small incision where the surgeon will remove the area of the bone or disc that is compressing a nerve in your spinal cord. This type of surgery is performed on patients who have a nerve compressed along their spinal cord, resulting in radiating pain.


Reasons for the procedure

Lumbar spinal stenosis is a common condition in elderly patients and may lead to progressive back and leg pain, muscular weakness, sensory disturbance, or problems with mobility. While nerve compression can be caused by a number of things, it is usually a result of one of the following spine conditions:

  • Spinal stenosis
  • Herniated disc
  • Bulging disc
  • Pinched nerve
  • Bone spurs
  • Sciatica
  • Arthritis of the spine
  • Facet disease
  • Foraminal stenosis
  • Annular tear


Minimally invasive decompression procedures:

  • Foraminotomy

    A foraminotomy is a decompression surgery that is performed to enlarge the passageway where a spinal nerve root exits the spinal canal. Conditions such as foraminal narrowing caused by bulging discs, herniated discs, scar tissue, bone spurs, thickening of the ligament and facet hypertrophy can be treated with a foraminotomy.

  • Laminotomy

    Laminotomy is the removal of a small portion of the lamina and ligaments, usually on one side to relieve pressure on the spinal cord compressed by spinal stenosis. Conditions such as spinal stenosis that are caused by a herniated disc, bulging disc, bone spurs, hypertrophy of the ligament flavum, facet hypertrophy and scar tissue can be approached surgically by doing a laminotomy.

  • Disectomy

    The surgical removal of herniated disc material that presses on a nerve root or the spinal cord. It involves removing the central portion of an intervertebral disc, which causes pain by stressing the spinal cord or radiating nerves.


What is our minimally invasive stabilization surgery?

During minimally invasive stabilization surgery the portion of the spine that is compressing the nerve root in the spinal cord and narrowing the spinal canal will be removed. An implant will immediately be placed in the now-free space to stabilize the spine and help prevent future spinal stenosis.


Reasons for the procedure

People who suffer from chronic neck and back pain and experience difficulty walking or standing for long periods of time. Back pain that is caused by a degenerative spine condition can prevent activities that bring enjoyment because the instability of the spine makes it difficult to move and twist without pain.


Types of minimally invasive stabilization procedures:

  • Anterior Cervical Fusion

    Anterior cervical discectomy and fusion is a surgery to remove a herniated or degenerative disc in the neck. A discectomy is a form of surgical decompression, so the procedure may also be called an anterior cervical decompression.

  • Transforaminal lumbar Interbody fusion

    Is a spinal fusion procedure that fuses the front and back section of the spine through a posterior approach. In this procedure, bone graft, or a bone graft substitute, is placed between vertebrae in order to fuse them and create a stronger and more stable spine.

  • Oblique Lumbar Interbody Fusion

    Oblique lumbar interbody fusion is a technique for fusion of the lumbar spine that overcomes these complications: spine curvature, fractured vertebrae, bulging discs, spine instability and spondylolisthesis (slipping out of vertebra).

    The procedure is performed under general anesthesia. OLIF is similar in approach to direct lateral interbody fusion (DLIF), but overcomes the drawback of DLIF in its ability to reach the last lumbar vertebra. This is made possible by obliquely approaching the vertebra and avoiding the pelvic bone.

  • SI Joint fusion

    The procedure typically involves three small titanium implants inserted in a minimally invasive procedure across the SI joint, and is designed to create a durable construct to stabilize the SI joint.

  • Anterior Lumbar Interbody Fusion

    The anterior lumbar interbody fusion (ALIF) is similar to the posterior lumbar interbody fusion (PLIF), except that in the ALIF, the disc space is fused by approaching the spine through the abdomen instead of through the lower back.
