Minimally-invasive transforaminal lumbar interbody fusion (TLIF) is an advanced surgical technique used to treat persistent lower back pain caused by spinal instability or nerve compression. This procedure removes a damaged intervertebrael disc and replaces it with a bone spacer while stabilizing the spine to encourage fusion between adjacent vertebraee. By approaching the spine through the foramen—the natural opening where nerve roots exit—the procedure allows for decompression and stabilization with reduced disruption to surrounding tissue.
At Princeton Neurological Surgery, minimally invasive TLIF procedures are performed by a neurosurgical team led by board-certified neurosurgeon Dr. Edward H. Scheid, Jr., who has performed more than 6,000 spine surgeries. Patients in Hamilton and Jersey City, NJ benefit from advanced imaging guidance, meticulous surgical planning, and techniques designed to relieve nerve compression while promoting long-term spinal stability.
What Is Minimally-Invasive TLIF?
Transforaminal lumbar interbody fusion refers to removing a diseased disc and placing bone graft material within the disc space to fuse two vertebraee together. The transforaminal approach crosses the foramen, allowing access to the disc space with a low risk of nerve injury and the ability to place graft material effectively.
Minimally-invasive TLIF may be recommended to treat:
- Nerve compression
- Disc space collapse
- Spondylolisthesis
- Degenerative disc disease
- Other causes of lower back instability
MRI and CT imaging are used to determine the appropriate surgical plan and implant selection.
How The Minimally-Invasive TLIF Procedure Is Performed
The procedure is performed under general anesthesia with the patient positioned face down. Two small incisions are made near the midline of the back. Rather than cutting muscle tissue, dilators are used to gently separate muscle fibers, minimizing trauma.
After confirming the correct spinal level with imaging guidance, portions of the lamina and pars interarticularis are removed to visualize the nerve roots. The damaged disc, bone spurs, and compressive debris are removed to relieve pressure on the nerves.
Bone graft material or bone morphogenetic protein (BMP) may be placed within the disc space to promote fusion. Often, two spacers containing graft material are positioned on either side of the interbody space. Metal rods and screws are inserted as needed to stabilize the spine while fusion occurs.
Once instrumentation placement is confirmed through imaging, the incisions are closed. The procedure typically lasts between three and four hours depending on the complexity of the condition.
Recovery After Minimally-Invasive TLIF
Most patients remain in the hospital overnight. Early movement and walking are encouraged to support circulation and healing. Physical therapy typically begins soon after surgery to help restore strength and mobility.
For several weeks, activities such as heavy lifting, bending at the waist, and twisting are restricted. Many patients return to non-strenuous work within two to three weeks. Clearance for more rigorous activities often occurs around three months, depending on the number of levels fused and individual healing progress.
Bone fusion continues over several months, and adherence to post-operative instructions is important for long-term success.
Risks Of Minimally-Invasive TLIF
Although considered safe and effective, minimally-invasive TLIF carries risks similar to other spinal fusion procedures. Rare complications may include:
- Infection
- Bleeding
- Nerve damage
- Blood clots
- Hardware failure
- Graft failure or nonunion
Careful patient selection, precise imaging guidance, and proper post-operative care help reduce these risks.
