Transforaminal Lumbar Interbody Fusion (TLIF)

1. What is TLIF?
Transforaminal Lumbar Interbody Fusion (TLIF) is a spinal fusion procedure used to stabilize one or more lumbar vertebral segments. The damaged disc is removed and replaced with an interbody cage, while screws and rods provide additional stabilization.

2. When is TLIF recommended?
TLIF may be considered for conditions such as lumbar spondylolisthesis, degenerative disc disease, spinal instability, recurrent disc problems, foraminal stenosis, or certain cases of spinal deformity when non-surgical treatment has not provided adequate relief.

3. How does TLIF relieve nerve pressure?
The procedure can include removal of bone, ligament, or disc material that is compressing spinal nerves. Restoring disc height may also help enlarge the neural foramen and reduce nerve compression.

4. How is TLIF performed?
The surgeon approaches the spine from the back, removes the affected disc through a transforaminal route, prepares the disc space, and inserts a bone-filled cage. Pedicle screws and connecting rods are then placed to stabilize the segment and promote fusion.

5. Can TLIF be performed using minimally invasive techniques?
Yes. TLIF can be performed using either conventional open surgery or minimally invasive techniques. Minimally invasive TLIF uses smaller incisions and specialized instruments and may reduce muscle disruption and blood loss in appropriately selected patients.

6. How long does TLIF surgery take?
The procedure commonly takes around 2–4 hours for a single level, although the duration varies according to the number of levels, surgical technique, anatomy, and complexity of the case.

7. What are the benefits of TLIF?
Potential benefits include stabilization of the affected spinal segment, reduction of mechanical back pain, decompression of compressed nerves, and improvement in leg pain and function. Recovery and improvement occur gradually as the spine heals and fusion develops.

8. What are the risks and complications?
Potential complications include infection, bleeding, nerve injury, dural tear and cerebrospinal-fluid leakage, blood clots, hardware problems, persistent pain, adjacent-segment disease, and failure of the vertebrae to fuse properly, sometimes requiring additional surgery.

9. Why consider India for TLIF?
India has specialized spine centres with experienced orthopedic spine surgeons and neurosurgeons, advanced imaging and navigation technologies, modern spinal implants, and comprehensive rehabilitation services at comparatively competitive treatment costs.
