Transforaminal Lumbar Interbody Fusion (TLIF)
A transforaminal lumbar interbody fusion (TLIF) is a type of spine surgery that involves approaching the spine from the back, or posterior, of the body to place a bone graft between two vertebrae. The procedure may be performed using minimally invasive surgical techniques.
The TLIF is a variation of the posterior lumbar interbody fusion (PLIF), in that it provides 360-degree fusion, decreases manipulation of neural structures, reduces damage to ligamentous elements, minimizes excessive bone removal, enhances biomechanical stability, and provides early mobilization.
Traditional, open spine surgery involves cutting or stripping the muscles from the spine. But today, a TLIF may be performed using minimally invasive spine surgery, a treatment that involves small incisions and muscle dilation, allowing the surgeon to gently separate the muscles surrounding the spine rather than cutting them. A minimally invasive approach preserves the surrounding muscular and vascular function and minimizes scarring.
Why do I need this procedure?
A spinal fusion procedure, such as a TLIF, may be recommended as a surgical treatment option for patients with a condition causing spinal instability in their lower back, such as degenerative disc disease, spondylolisthesis, or spinal stenosis, which has not responded to conservative treatment measures (rest, physical therapy, or medication). The symptoms of lumbar spinal instability may include pain, numbness, and/or muscle weakness in the low back, hips, and legs.
Your surgeon will take a number of factors into consideration before recommending a TLIF, including the condition to be treated, your age, health, lifestyle, and your anticipated level of activity following surgery. Please discuss this treatment option thoroughly with your spinal care provider.
How Is A Minimally Invasive TLIF Performed?
First, your surgeon will make two small incisions in the skin of your back over the vertebra(e) to be treated. Depending on the instrumentation to be used, the incision could be as small as approximately 3 centimeters. In a traditional open TLIF, a 3- to 6-inch incision is typically required.
The nerve roots are then moved to one side, and the disc material is removed from the front (anterior) of the spine. A bone graft is then inserted into the disc space. The bone graft material acts as a bridge, or scaffold, on which new bone can grow. Screws and rods are inserted to stabilize the spine while the treated area heals and fusion occurs, and the ultimate goal of the procedure is to restore spinal stability.
Your surgeon will then close the incisions, which typically leaves behind only a small scar or scars.
OrthoNC offers comprehensive spine expertise
OrthoNC’s spine specialists diagnose spine problems and design custom treatment plans built on a conservative, non-surgical approach. Most patients find relief through treatments including guided injections, specialized physical therapy, exercise, activity modification, and medication. When conservative care does not relieve symptoms, our highly skilled surgeon offers proven, evidence-based surgical options. Together with you, we will determine the right course of action.
