Extreme Lateral Interbody Fusion (XLIF)

An extreme lateral interbody fusion (XLIF) is a minimally invasive procedure that involves accessing the spine through the side of the body. XLIF address spinal disorders and alleviate chronic back or leg pain that has not improved with other treatments, such as steroid injections, physical therapy, and pain medication. This results in less tissue disruption and shorter recovery time. The use of XLIF in spinal surgery has shown to provide significant pain relief after one year. This improvement in pain levels is not only noticeable but also clinically significant. Additionally, XLIF has led to a marked improvement in functionality one year after the surgery, and this enhancement is also clinically meaningful.

What Is an Extreme Lateral Interbody Fusion?

Extreme Lateral Interbody Fusion (XLIF) is a minimally invasive surgical procedure designed to treat various spinal conditions, including degenerative disc disease, spondylolisthesis, and scoliosis. Unlike traditional spinal fusion surgeries that access the spine from the back or front, XLIF approaches the spine from the side, avoiding major muscles, bones, and ligaments, thus minimizing tissue disruption. The procedure involves making a small incision on the patient’s side, navigating to the spine through the psoas muscle using specialized instruments and real-time imaging, removing the damaged disc, and inserting an implant filled with bone graft material to maintain disc height and promote fusion between the vertebrae.

The benefits of XLIF include smaller incisions, less muscle disruption, reduced recovery time, and less postoperative pain compared to traditional approaches. It is effective in reducing pain and improving spinal stability and functionality. XLIF is commonly used for conditions like degenerative disc disease, herniated discs, spondylolisthesis, and scoliosis, offering significant improvements in pain relief and overall function for patients with spinal disorders.

What Conditions Does an XLIF Treat?

XLIF is useful for numerous conditions that require fusion of the lumbar spine. These include:

  • Disc Degeneration: Spinal surgery can reduce motion between vertebrae to adjust alignment, restore proper disc height and alleviate pain in patients with disc degeneration. 
  • Degenerative Spondylolisthesis: XLIF can also reduce motion between vertebrae for people with Spondylolisthesis — an affliction where a vertebra slips forward and over another.
  • Degenerative scoliosis: People with this medical condition often undergo XLIF to return their spine to proper alignment and disc height.  
  • Foraminal Stenosis: An XLIF can increase the height of a disc alleviating the narrowing of the foramen around an spinal nerve.
  • Recurrent Lumbar Herniations: With recurrent herniated disc there is a loss of disc height due to degeneration. An XLIF removes all the herniated and degenerative disc material and implants a PEEK cage which restores disc height.

How to Prepare for a XLIF Spine Fusion 

Preparing for XLIF (Extreme Lateral Interbody Fusion) surgery involves several important steps to ensure the best possible outcome and smooth recovery. Here is a guide on how to prepare for your XLIF surgery:

Weeks Before Surgery

  1. Consult with Your Surgeon: Have a detailed discussion with your surgeon about the procedure, including the benefits, risks, and expected outcomes. This is the time to ask any questions you may have.
  2. Medical Evaluation: Undergo a comprehensive medical evaluation, which may include blood tests, an EKG, and imaging studies such as X-rays, MRI, or CT scans. These tests help assess your overall health and the specific condition of your spine.
  3. Medication Review: Provide your surgeon with a complete list of medications you are taking, including prescription drugs, over-the-counter medications, and supplements. Your surgeon may advise you to stop taking certain medications, such as blood thinners, several days before surgery.
  4. Quit Smoking: If you smoke, it’s advisable to stop smoking well before your surgery, as smoking can interfere with healing and increase the risk of complications.
  5. Healthy Lifestyle: Maintain a healthy diet and stay active within the limits of your condition. Proper nutrition and physical activity can help improve your overall health and recovery.

Days Before Surgery

  1. Preoperative Instructions: Follow any specific instructions given by your surgeon. This may include fasting (not eating or drinking) after midnight the night before surgery.
  2. Arrange Transportation and Support: Arrange for someone to drive you to and from the hospital on the day of your surgery. You should also arrange for someone to stay with you for the first few days after surgery to assist with daily activities.
  3. Home Preparation: Prepare your home for your return from the hospital. Set up a comfortable resting area with easy access to necessary items, and make sure pathways are clear to avoid tripping hazards.

Day of Surgery

  1. Hygiene: Follow any specific bathing instructions provided by your healthcare team. You may be asked to shower with an antibacterial soap to reduce the risk of infection.
  2. Clothing: Wear loose, comfortable clothing to the hospital. Avoid wearing any jewelry, makeup, or nail polish.
  3. Arrival at the Hospital: Arrive at the hospital or surgical center at the designated time. Bring a form of identification, insurance information, and any necessary paperwork.
  4. Preoperative Checklist: You will be checked in and may undergo final preoperative assessments, such as blood pressure and temperature checks.

Mental Preparation

  1. Stay Informed: Educate yourself about the procedure and what to expect during recovery. Knowing what lies ahead can help reduce anxiety and stress.
  2. Relaxation Techniques: Practice relaxation techniques such as deep breathing, meditation, or visualization to help manage pre-surgery anxiety.

Post-Surgery Planning

  1. Recovery Plan: Discuss your post-surgery recovery plan with your surgeon, including pain management, physical therapy, and follow-up appointments.
  2. Prepare for Assistance: Ensure you have the necessary support system in place for your recovery period. This includes help with household tasks, transportation to follow-up appointments, and assistance with activities of daily living.

By following these preparation steps, you can help ensure a smoother surgical experience and a more successful recovery after your XLIF surgery.

How Is XLIF Surgery Performed?

To access the spine, a neurosurgeon will make a small incision and insert a dilator — an instrument placed between the side of the abdomen and the muscles covering the spine. They will then use retractors to widen the muscle tissue, remove afflicted disc material and insert the bone graft. During the operation, surgeons will use an electromyography (EMG) to monitor the position of the surgical instruments in relation to the nerves. 

XLIF (Extreme Lateral Interbody Fusion) surgery is a minimally invasive spinal procedure that involves the following steps:

  1. Preoperative Preparation: The patient is positioned on their side on the operating table. General anesthesia is administered to ensure the patient is unconscious and pain-free during the procedure.
  2. Incision: A small incision is made on the side of the patient, typically between the ribs and hip. This lateral approach allows the surgeon to avoid major back muscles, bones, and ligaments.
  3. Guidance and Access: The surgeon uses fluoroscopy (live X-ray) to guide instruments to the correct location. A specialized retractor is inserted through the incision to gently move aside muscles and tissues, providing a clear path to the spine.
  4. Disc Removal: Once the retractor is in place, the surgeon removes the damaged or degenerated intervertebral disc material. This creates space for the interbody fusion.
  5. Implant Placement: A bone graft or interbody cage filled with bone graft material is inserted into the empty disc space. This helps to maintain proper spine alignment and promotes the growth of new bone, leading to fusion of the adjacent vertebrae.
  6. Closure: After the implant is securely in place, the retractor is removed, and the incision is closed with sutures or staples. A small bandage is applied to cover the incision site.
  7. Recovery: The patient is monitored as they wake up from anesthesia. Since the procedure is minimally invasive, many patients can walk on the same day and may only require an overnight hospital stay.

Overall, XLIF surgery is designed to minimize tissue disruption, reduce pain, and facilitate a quicker recovery compared to traditional spinal fusion procedures.

What to Expect From an XLIF Surgery

The following is what you can expect before and after an XLIF surgery.

Before XLIF Surgery

Before undergoing XLIF surgery, you will have a thorough preoperative evaluation, including a review of your medical history, a physical examination, and imaging studies like X-rays, MRI, or CT scans to assess the condition of your spine and plan the surgery. During a consultation, your surgeon will discuss the procedure in detail, explaining the benefits, risks, and what to expect during recovery, and will address any questions or concerns you may have. You will receive specific pre-surgery instructions regarding medications, fasting, and preparation for surgery, which may include stopping certain medications such as blood thinners and refraining from eating or drinking after midnight on the day of surgery. Additionally, preoperative tests such as blood tests and an EKG may be performed to ensure you are fit for surgery.

After XLIF Surgery

Immediately after the procedure, you will be taken to a recovery area where medical staff will monitor your vital signs and ensure you are waking up safely from anesthesia. Pain and discomfort are expected but are usually less intense than with traditional spine surgery, and pain medication will be provided as needed. One of the key benefits of XLIF surgery is the ability to start moving soon after the procedure; most patients are encouraged to walk the same day or the day after surgery, which aids in recovery and reduces complications. XLIF typically requires a shorter hospital stay compared to traditional procedures, with some patients going home the same day or after an overnight stay.

Follow-up appointments will be scheduled to monitor your progress, remove stitches or staples if necessary, and check the healing of the surgical site and fusion. A physical therapy program may be recommended to help restore strength, flexibility, and mobility, accelerating your return to normal activities. While you may resume light activities relatively quickly, heavy lifting, bending, and twisting should be avoided for a period specified by your surgeon, with full recovery and return to strenuous activities taking a few months. You will be advised on signs of potential complications, such as increased pain, swelling, redness, or drainage from the incision site, fever, or numbness; if you experience any of these symptoms, you should contact your healthcare provider immediately. Overall, XLIF surgery aims to reduce recovery time, minimize pain, and facilitate a quicker return to daily activities compared to traditional spinal fusion surgeries.

Advantages of Using Minimally Invasive XLIF Surgery Over Traditional Spine Fusion Surgeries

XLIF represents a departure from conventional methods as it allows surgeons to reach the spaces between spinal discs via the patient’s side, rather than from the front or back, thereby sparing significant back muscles, bones, and ligaments. The benefits of XLIF include:

  1. 15% Reduced surgery time: XLIF procedures can be completed in as little as one hour, minimizing both surgical duration and the time patients spend under anesthesia.
  2. 90% Decreased blood loss: This minimally invasive approach causes less disruption to tissues, resulting in reduced blood loss and minimal scarring.
  3. Lower post-operative pain: By accessing the intervertebral disc space from the patient’s side, XLIF avoids disturbing sensitive back muscles, bones, and ligaments. As a result, many patients are able to walk on the same day as their surgery.
  4. 50% Shorter hospital Stay: Compared to traditional procedures that often require days of hospitalization and immobility, XLIF typically necessitates only an overnight hospital stay in some cases.
  5. Faster return to normal activities: While full recovery may take a few months, patients undergoing XLIF usually begin walking the day of surgery, a significant improvement over the six months or longer typically required for recovery from traditional procedures.

What Types of Spinal Fusion Are Performed in the Back?

Every type of spinal fusion surgery follows a similar process — removal of the vertebrae before replacing them with a bone graft, rods and screws. The difference lies in how the spine is accessed. Often, your surgeon will decide the type of approach you need based on factors like condition, location and anatomical structure of the part of the spine affected. 

While XLIF involves accessing the spin through the side, other types of spinal fusion surgeries include: 

  • Posterior Lumbar Interbody Fusion (PLIF): This surgery involves accessing the spine through the middle of the lower back to remove a degenerative disc, replacing it with a surgical PEEK cage packed with bone graft for stability. 
  • Anterior Lumbar Interbody Fusion (ALIF): ALIF involves accessing the spine through the stomach. Surgeons then insert a cage and a bone graft on the front segment of the spine. Often times, surgeons then have the patient flipped over onto their stomach and insert screws and rods to create a secondary posterior fusion.
  • Transforaminal Lumbar Interbody Fusion (TLIF): TLIF avoids the major back muscles, starting just off midline toward your side targeting the facet joint as a bone landmark.  From there a surgeon can navigate the spinal nerve and disc space to perform a fusion. 
  • Oblique Lateral Interbody Fusion (OLIF): While similar to ALIF, The incision is to one side of your stomach and then approaching from front to back to the disc to perform a fusion.

What Are the Potential Complications of XLIF? 

Spinal fusion surgeries are generally very safe. However, just like any procedure, you should be aware of risks like:

  • Pain at the site of the bone graft
  • Poor incision healing
  • Infection 
  • Blood loss
  • Blood clots
  • Nerve damage around the surgical area 

XLIF Surgery Recovery FAQs

The following are answers to common questions clients often have about XLIF surgery recovery:

The XLIF recovery process depends on the individual, with full recovery often taking several months. It might also involve a period of restricted activity and pain management.

After surgery, your back may feel stiff or sore. When home, avoid bending, lifting or twisting to do chores or other physical activities. This will help reduce further pain and encourage an easier healing process.

It’s best to wait 24 to 48 hours after surgery to shower. When showing, rinse your incision very carefully with soap and water before gently patting it dry.

You should wear your back brace until your follow-up appointment after surgery. The doctor will assess your recovery and determine whether you still need to wear it.

It can take several months for the vertebrae to fuse after surgery. You’ll want to follow postoperative care closely to ensure a successful healing and fusion.

You might return to work within three to six weeks for less strenuous jobs. However, you’ll likely have additional recovery time before returning to a more physically demanding job.

You can typically resume walking after surgery and while in the hospital. More intensive exercises like working out or running could take several months or when a physical therapist approves.

Physical therapy usually starts six weeks to three months following surgery and continues while at home. Therapy will help strengthen your back, support healing and let you return to your favorite activities.
