Minimally Invasive Spine Surgery

For many patients considering spinal surgery, the fear of a large incision, hospital stays and a long recovery period was enough to scare them away from surgery.  However, innovative new technology now allows for Spinal Surgery to be performed through an incision as small as an inch in what is known as a Minimally Invasive fashion.With this Minimally Invasive approach, small surgical instruments and a tiny camera are slipped between tissue and muscle fibers to access the spine.


Once these instruments have been inserted, the surgeon will use real-time imaging, known as fluoroscopy, to navigate the structures of the spine and remove herniated portions of the spinal discs or bone spurs causing nerve irritation. Once the procedure is completed, only small stitches and a bandage is required and most patients are able to return home the same day.

Minimally Invasive Lumbar Fusion

The goal of Minimally Invasive Spinal Fusion Procedure (and open Spinal Fusion) is to remove portions of, or the entire, spinal disc and/or any bone material that may be causing spinal nerve compression to reduce impingement on the targeted nerve roots.


Once the disc(s) have been partially or completely removed, an implant is placed into the space where the spinal disc once was in an effort to restore the normal height of the spinal disc space.  This implant will also contain bone graft that triggers a biological response, which, over time, will knit together with the vertebrae above and below and form one continuous stable vertebrae.  Additional plates, rods or screws may also be used to ensure stability of the spine.

Depending upon the area of the spinal condition and the best option for the patient, Lumbar Spinal Fusions can have several different approaches, including:

  • ALIF (Anterior Lumbar Interbody Fusion)
  • TLIF (Transforaminal Lumbar Interbody Fusion)
  • PLIF (Posterior Lumbar Interbody Fusion)
  • XLIF (Extreme Lateral Interbody Fusion)

Many of these procedures can be performed on an outpatient basis and utilize Minimally Invasive approaches that minimizes disruption to surrounding muscle and tissue.

Minimally Invasive Cervical Fusion

Cervical instrumentation and fusion is used to treat conditions of the spine which cause spinal instability such as Degenerative Disc Disease or spinal arthritis.


During this procedure, a small incision (usually 1inch) is made toward the front of the cervical spine.  Through this incision, small surgical tools are used to remove the damaged spinal disc(s) as well as any bone spurs that may be causing irritation to the surrounding nerves.  Once the disc space has been cleared, a small implant that is filled with bone graft material is inserted.  This bone graft material will eventually fuse into one complete vertebrae and restore stability to the spine.

To further stabilize the spine, instrumentation such as plates, small rods or screws are attached the the vertebrae above and below.

A Microdiscectomy is a procedure that requires a small (1-2 inch) incision and is used to treat pain caused as a result of disc herniations by removing only the herniated portions of the spinal disc while leaving the remaining portions of the disc intact.  This procedure is commonly performed for those who are experiencing pain that radiates into the buttocks and legs (Sciatica) but can also be performed for patients with cervical or thoracic radiculopathy.  By removing the herniated portions of the disc, and any bone spurs, the spinal nerves that are causing pain and numbness are no longer impinged.


In most cases, a Microdiscectomy can be performed on an outpatient basis due to the reduced trauma to the spine and muscular structures.   In fact, most patients are up and walking shortly after this procedure and physical therapy will begin within a few days of the procedure if needed.

Artificial Disc Replacement (Cervical)

The purpose of the artificial disc used in the surgery is to eliminate nerve root, spinal canal or spinal cord compression and preserve motion of the cervical spine. This procedure requires a small (1 inch) incision and is an alternate to anterior cervical discectomy (and) fusion (ACDF). The CADR procedure involves the surgical replacement of the cervical disc implant that allows mobility of the neck. This procedure is a similar principle to a knee or hip replacement procedure.


This new procedure of CADR is minimally invasive and approved by the Food and Drug Administration (FDA). Cervical Artificial Disc Replacement may be preferred over traditional cervical disc surgery because it allows more movement and reduces stress on the neck.

Minimally Invasive Laminectomy
A Laminectomy is a type of surgery which relieves pressure on the spinal nerves and improves symptoms caused by the narrowing of the spinal canal in the lumbar or cervical spine. This minimally invasive procedure involves the trimming or removal of the lamina, which is the domed piece of bone at the back of the vertebra.
During the procedure the lamina and any bone spurs on the vertebrae are removed so that the trapped spinal nerve(s) can be decompressed.  Once the nerve is decompressed, back or neck pain and radiating pain in the arms or legs will subside. In most instances, patients who undergo a Lumbar Laminectomy are able to return home the same day as their procedure.

Laser Spine Surgery

The term “laser spine surgery” has become increasingly popular over the years and many patients often ask their doctor if they are candidates for this type of surgery.  The truth is that “laser” spine surgery is term used to make what is already known as Minimally Invasive Spine Surgery sound fancier.  Despite what you may have been told, lasers can not correct the issue within your spine and a surgeon still needs to decompress the spinal nerves or stabilize the spine in order to relieve your pain.  However, modern advancements in Minimally Invasive Spine Surgery now use incisions as small as an inch and many patients are able to return home the same day.  At Virella Spine Surgery, we have been at the forefront of Minimally Invasive Spine Surgery and Dr. Anthony Virella is considered a pioneer in this field.
