Transforaminal lumbar interbody fusion (TLIF) is a surgical procedure used to stabilize the spine and relieve nerve compression. It is performed through the back and involves removing a disc, placing an implant, and allowing the bones to fuse together.
Quick Facts:
- Performed through the back of the spine
- Stabilizes unstable or painful segments
- Relieves nerve compression
- Often used for spondylolisthesis and degenerative conditions

WHAT IS TLIF?
TLIF is a fusion procedure that involves:
- Removing a damaged disc
- Relieving pressure on nerves
- Placing a spacer (interbody cage) into the disc space
- Stabilizing the spine with screws and rods
- Allowing the bones to fuse over time
👉 The goal is to stabilize the spine and relieve symptoms caused by instability or degeneration
WHY IS TLIF PERFORMED?
TLIF is used when both nerve compression and instability or disc-related pain are present.
Common Indications
- Spondylolisthesis
- Degenerative disc disease with instability
- Recurrent disc herniation
- Foraminal stenosis with collapse of disc height
- Failed prior decompression
👉 TLIF addresses both decompression and stability in one procedure
SYMPTOMS THAT MAY REQUIRE TLIF
Common Symptoms
- Leg pain (sciatica)
- Back pain (mechanical pain)
- Numbness or tingling
- Weakness
Typical Pattern
- Combination of leg pain and back pain
- Symptoms that worsen with activity or standing
🚨 When Surgery May Be More Urgent
- Progressive weakness
- Severe nerve compression
- Loss of bowel or bladder control
HOW IS THE PROCEDURE PERFORMED?
Step-by-Step Overview
- Anesthesia
- Performed under general anesthesia
- Posterior Approach
- Incision made in the lower back
- Decompression
- Nerve roots are decompressed
- Bone or disc material causing compression is removed
- Disc Removal
- The disc is removed from one side (transforaminal approach)
- Interbody Cage Placement
- A spacer is placed into the disc space
- Restores disc height and alignment
- Instrumentation
- Screws and rods are placed to stabilize the spine
- Fusion
- Bone graft is used to promote healing across the segment
👉 TLIF provides both decompression and structural support
OUR APPROACH
We focus on using TLIF selectively when fusion adds clear value.
- Not all patients with nerve compression require fusion
- We carefully assess stability and disc health
- We aim to treat the correct level and avoid unnecessary extension
- The goal is durable relief with the least invasive effective approach
👉 TLIF is most effective when there is a clear need for both decompression and stabilization
WHAT TO EXPECT
Before Surgery
- MRI, CT, and standing X-rays
- Likely Bone mineral density scan
- Evaluation of alignment and disc height – likely scoliosis x-rays
- Planning of levels and approach
Day of Surgery
- Performed under general anesthesia
- Procedure length depends on number of levels
After Surgery
- Hospital stay is common
- Gradual improvement in symptoms
- Recovery over weeks to months
- Fusion develops over time
OUTCOMES & RISKS
Potential Benefits
- Relief of nerve-related symptoms
- Improved stability
- Reduction of mechanical back pain
- Restoration of disc height and alignment
Risks
- Infection
- Bleeding
- Nerve injury
- Failure to fuse (pseudarthrosis)
- Hardware complications
- Adjacent segment stress over time
👉 Outcomes depend heavily on appropriate patient selection and successful fusion
FREQUENTLY ASKED QUESTIONS
How is TLIF different from a laminectomy?
Laminectomy decompresses nerves only, while TLIF also stabilizes the spine.
How is TLIF different from ALIF or OLIF?
TLIF is performed from the back, while ALIF and OLIF approach the spine from the front or side.
Will I lose motion in my spine?
Motion is lost at the fused level, but overall function is typically preserved.
How long does fusion take?
Fusion occurs gradually over several months.
FOR REFERRING PHYSICIANS
- Refer patients with:
- Spondylolisthesis
- Instability
- Recurrent disc herniation
- Foraminal stenosis with collapse
- Imaging:
- MRI lumbar spine
- X-rays (including flexion/extension)
- CT when evaluating fusion or bony anatomy
- Consider:
- TLIF vs ALIF/OLIF based on anatomy and goals
