TLIF
Transforaminal Lumbar Interbody Fusion — a guide for patients and families
A guide by Dr. Amit Chanduka, Neurosurgeon & Spine Surgeon, explaining what TLIF is, why it might be recommended, and what to expect before, during, and after surgery.
Book ConsultationWhat is TLIF?
TLIF stands for Transforaminal Lumbar Interbody Fusion. It is one of the most common types of spine surgery used to treat problems in the lower back (lumbar spine) that cause pain, instability, or pressure on the nerves.
The approach the surgeon takes to reach the target for nerve decompression and fusion.
The region in the lower back of the spine that usually requires this procedure.
The place of actual work — the space between two spinal bones, or vertebrae.
The ultimate aim: uniting two adjacent spinal bones so that instability is completely cured.
In simple terms: the procedure creates an approach in the lower back to remove the disc material, decompress the nerves, and replace the disc space with a bone graft or an artificial spacer, usually made of PEEK or titanium. Screws are then placed in the bones for fixation. The entire procedure is carried out with the aim of achieving fusion — a permanent union — between two adjacent bones.
Why might I need this surgery?
Dr. Chanduka recommends TLIF only when more conservative treatments — such as physiotherapy, medication, and injections — have not given enough relief, and when scans clearly show a problem that surgery can address. Common reasons TLIF is recommended include:
- Spondylolisthesis — when one vertebra has slipped forward over the one below it
- Facetal arthropathy — when the joints between two adjacent vertebrae become sore and cause nagging pain
- Degenerative disc disease with ongoing instability or nerve pressure
- A disc that has herniated again after previous surgery (failed back syndrome)
- Spinal instability causing significant back or leg pain
Surgery is never the first option and is only suggested after a full discussion of your scans, symptoms, and other treatments. You are always welcome to ask about alternatives before deciding.
What happens during the procedure
TLIF is done under general anaesthesia, so you are fully asleep and feel nothing during the operation. Broadly, the steps are:
- 1A small incision is made in the lower back.
- 2The surgeon carefully moves the muscles aside (rather than cutting them) to reach the spine.
- 3A cut is made on the bone (laminectomy and facetectomy, unilateral or bilateral depending on the pathology).
- 4The damaged disc is removed through the natural opening at the side of the spine.
- 5A small cage or bone graft is placed in the empty disc space to restore height and support.
- 6Screws and rods are placed to hold the vertebrae steady while the bone fuses.
- 7The incision is closed with a temporary drainage system in place.
Preparing for your surgery
In the days before
- A pre-anaesthetic checkup is done by the anaesthesiologist.
- Follow any fasting instructions given by the hospital (usually no food or water after midnight the night before, or 8 hours prior to surgery).
- Tell the team about all medicines and supplements you take, especially blood thinners — some may need to be paused before surgery.
- Arrange for someone to help you at home for the first two to three weeks after discharge.
- If you smoke, stopping well before surgery helps the fusion heal better.
On the day
Take any medicines instructed by the anaesthetist in your pre-op advice.
The nursing team will check for and arrange blood products if needed — this is usually rare for a single-level surgery in a healthy individual with a good pre-operative haemoglobin level (typically above 12 g%).
Recovery: what to expect
In hospital
Most patients stay in hospital for three to four days after TLIF. You will usually be encouraged to sit up and take a few short, supported walks within a day of surgery — gentle movement early on actually helps recovery. A lumbosacral brace may be recommended.
At home
- Gradual increase in walking is encouraged; avoid bending, twisting, or lifting anything heavy for the first six to eight weeks.
- Some pain and stiffness at the incision site is normal and is managed with medication.
- Physiotherapy is usually introduced 6 to 8 weeks after surgery to rebuild strength safely.
- Most people return to light daily activities within four to six weeks, and to work within six to twelve weeks, depending on the nature of the job — desk-based work is usually quicker than physical labour.
- Full fusion of the bone continues over several months, so it is important to follow activity guidance even after you start feeling better.
These timelines are general guidance, not a promise. Your own recovery will be discussed with you at each follow-up, based on how your fusion is progressing on scans.
Risks and when to call us
TLIF is a well-established and generally safe procedure, but like any surgery it carries some risk. These are discussed in detail before you consent to surgery, and include infection, bleeding, nerve irritation, and the small possibility that the bone does not fuse as expected, which can sometimes need further treatment.
Please contact the clinic promptly if, after surgery, you notice:
- Fever, or redness/discharge from the incision
- New or worsening numbness, weakness, or pain in the legs
- Difficulty controlling your bladder or bowel
- Severe pain not relieved by your prescribed medication
