Minimally Invasive Transforaminal Lumbar Interbody Fusion (TLIF)

Minimally Invasive Technique Stabilizing the Spine and Relieving Pressure on Irritated Nerves

A procedure where damaged herniated disc and arthritic bone is removed and substituted with a spacer. This is meant to remove the pressure off the nerve and spinal cord, and stabilize the painful motion in the vertebrae from above and below.

This can be done at 1 or multiple levels.

TLIF may be recommended for patients with conditions such as spondylolisthesis, spinal instability, recurrent disc herniation, degenerative disc disease, or lumbar spinal stenosis when non-surgical treatments have not provided adequate relief. (MIS-TLIF)

  • After anesthesia is given, an incision is made directly over the spine in the area of interest. This incision is guided with x-ray.

    Some bone is cut out, and the injured disc is removed, and the nerves are carefully relieved of the damaging pressure.

    A spacer is placed. This is repeated at multiple levels as needed. Screws are placed in the bones above and below the spacer to stabilize the area.


    Intraoperative X-rays are done to confirm placement, and the wound is checked for bleeding and the incision is sutured closed.

    1. Decompress the nerves

    2. Take away the painful motion

    3. Accomplish a successful fusion

  • Depending on medical history, age, and surgical extent, some patients may spend one or multiple nights in the hospital for therapy and pain control.

    Soreness from the incision site can remain for a week or two. Muscles can spasm from surgery as they do not like getting pushed around. Nerve relief can be felt within days.

    The low back can feel sore, but it’s a different type of discomfort that before surgery.

    The fusion process may take up to 12 weeks for bone graft to consolidate, but symptoms typically improve much sooner.

    Return to work times vary, some people are able to return to light work 3 week after surgery. For those with a very physically demanding job, return to work may not happen until 6-12 weeks after surgery.

    1. Relieve 50% of the back pain

    2. Relieve 70% of the leg pain

  • There is no surgery without risks. They include but are not limited to: bad reaction to anesthesia, injury to the major vessels in the belly, injury to intestines, surgical site infection, prolonged pain, nerve injury, implant failure, failure of fusion, spinal fluid leak, and the need for additional surgery.

FAQs

1. Why would someone have a TLIF?

TLIF is generally considered when a patient has a structural problem in the lumbar spine that cannot be adequately addressed with non-surgical treatment or decompression alone.

Common reasons for TLIF include:

Lumbar Spondylolisthesis

Spondylolisthesis occurs when one vertebra shifts forward relative to another. This can cause back pain, spinal instability, and compression of the nerves.

Lumbar Spinal Stenosis

Spinal stenosis occurs when there is narrowing around the spinal nerves.

In some patients, decompression alone may be appropriate. When decompression would create or worsen instability—or when significant instability already exists—a fusion such as TLIF may be considered.

Degenerative Disc Disease

Discs can lose height and become painful as they degenerate. In carefully selected patients, removing the painful disc and stabilizing the segment may help relieve symptoms.

Recurrent Disc Herniation

Patients who develop a recurrent disc herniation, particularly when there is associated disc degeneration or instability, may sometimes require fusion rather than another isolated discectomy.

Foraminal Stenosis

The neural foramen is the opening through which a spinal nerve exits the spine.

Loss of disc height can narrow this opening and compress the nerve. TLIF can restore disc height and provide indirect and direct decompression of the affected nerve.

Spinal Instability

When abnormal motion between vertebrae contributes to pain or nerve compression, fusion may be recommended to stabilize the affected segment.

2. How long does TLIF surgery take?

The operative time depends on the number of levels treated, surgical approach, anatomy, and whether the patient has had previous surgery. For a one level surgery, it can take between 2-3 hours given falling asleep with anesthesia, positioning on the belly, performing the surgery, closing incisions, and then waking up.

3. How long will I be in the hospital after TLIF?

Some patients can go home the same day or after a short hospital stay, while others may require one or more nights depending on the procedure and their medical needs.

4. Is TLIF surgery painful?

Some postoperative pain at the incision sites is expected. It will feel like you got stabbed for a week or two, but the leg pain should immediately improve. Pain usually improves progressively as the surgical site heals.

5. How long does it take for a TLIF to fuse?

Fusion develops gradually. Bone healing commonly takes several months and may continue for 6–12 months or longer, but the recovery from surgery is between 4-12 weeks.

6. Can TLIF relieve sciatica?

TLIF can relieve sciatica when the spinal nerves are compressed by a condition that is appropriately treated with decompression and fusion.

7. Will I have screws in my back after TLIF?

Yes. Pedicle screws and rods are commonly used to stabilize the spine while the fusion heals.

8. Can TLIF be done without screws?

In most standard TLIF procedures, screws are used to provide stability. The exact construct depends on the patient's anatomy and surgical needs.

9. Can a TLIF fail?

Like any fusion procedure, TLIF can fail to achieve solid fusion or may not completely relieve symptoms. Hardware complications, nonunion, recurrent symptoms, and adjacent-level problems can occur.

10. What is the difference between TLIF and ALIF?

TLIF approaches the spine from the back, while ALIF approaches the spine from the belly. Both can be used to restore disc height and achieve lumbar fusion, but the advantages and risks of each approach differ.

11. What positions should I sleep in after surgery?

Whatever position you find comfortable is the right one. Some prefer on the side, some on the belly, some on the back; there is no one universal position to sleep in.

12. What Is Recovery Like After TLIF Surgery?

Recovery varies depending on the number of levels treated, surgical technique, overall health, physical condition, and the patient’s underlying diagnosis.

Immediately After Surgery

Patients are generally encouraged to get out of bed and walk soon after surgery.

Pain is typically managed with a combination of medications and activity modification.

First Few Weeks

Walking is encouraged, while heavy lifting, repetitive bending, and twisting are generally restricted.

Patients gradually increase their activity as their symptoms and recovery allow.

6–12 Weeks

Many patients begin increasing their daily activities substantially during this period.

Physical therapy may be recommended depending on the patient’s needs.

3–6 Months

The fusion continues to mature during this period.

Many patients are able to return to increasingly normal activities, although the timeline varies significantly between individuals.

Complete Fusion

Bone healing continues for many months after surgery. Radiographic evidence of a mature fusion may take 6–12 months or longer.

13. When Can I Return to Work After a minimally invasive TLIF?

Return-to-work timing depends heavily on the type of work you do.

Desk/office work

Some patients may return relatively quickly, depending on pain, mobility, and ability to sit comfortably.

Moderate physical work

A longer recovery period is generally required.

Heavy labor

Patients who perform repetitive lifting, bending, twisting, or heavy physical labor may require several months before returning to unrestricted work.

Your surgeon will provide individualized restrictions based on your procedure and recovery.

14.When Can I Exercise After TLIF?

Walking is typically encouraged early after surgery.

More strenuous activities are gradually reintroduced as healing progresses.

Your recovery plan may eventually include:

  • Walking

  • Core strengthening

  • Physical therapy

  • Cardiovascular exercise

  • Strength training

  • Sport-specific conditioning

High-impact activities and heavy lifting should generally be avoided until your surgeon determines that the fusion has adequately healed. How long will I be in the hospital after TLIF?

Some patients can go home the same day or after a short hospital stay, while others may require one or more nights depending on the procedure and their medical needs.

How do I know if a minimally invasive TLIF (MIS-TLIF) is right for me?

A diagnosis of spinal stenosis, spondylolisthesis, degenerative disc disease, or a recurrent disc herniation does not automatically mean you need a fusion.

The right treatment depends on your individual anatomy, symptoms, goals, and previous treatments.

If you are considering lumbar fusion surgery, a comprehensive evaluation can help determine whether TLIF—or another treatment—is the best option for you.

The first step is determining exactly what is causing your symptoms. Once the diagnosis is clear, we can discuss whether nonsurgical treatment, disc replace, fusion, or another procedure is most appropriate for you.
