Spinal fusion is a surgical procedure in which two or more vertebrae are joined or fused together. Fusion surgeries typically require the use of bone graft to facilitate fusion. This involves taking small amounts of bone from the patient’s pelvic bone (autograft), or from a donor (allograft), and then packing it between the vertebrae in order to “fuse” them together. This can be accomplished either posteriorly or between the vertebral bodies. When it is done between vertebral bodies, bone graft, along with a biomechanical spacer implant, will take the place of the intervertebral disc, which is entirely removed in the process.
Spinal fusion surgery is a common treatment for such spinal disorders as spondylolisthesis, scoliosis, severe disc degeneration, or spinal fractures. Fusion surgery is usually considered only after extensive non-operative therapies have failed. Two common fusion surgeries available at World Class Neurosurgery Hospitals in India for Spinal Disorders include posterior fusion and interbody fusion such as PLIF, 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 bone graft between two vertebrae. The procedure may be performed using minimally invasive surgical techniques.
Spinal fusion (such as a TLIF) is a surgical technique to stabilize the spinal vertebra and the disc or shock absorber between the vertebra. Lumbar fusion surgery is designed to create solid bone between the adjoining vertebra, eliminating any movement between the bones. The goal of the surgery is to reduce pain and nerve irritation.
Spinal fusion may be recommended for conditions such as spondylolisthesis, degenerative disc disease or recurrent disc herniations. Surgeons perform lumbar fusion using several techniques. This article describes the transforaminal lumbar interbody fusion (TLIF) fusion technique.
How is a Minimally Invasive TLIF Performed?
Spinal Access and Bone Removal
First, your surgeon will make a small incision 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 muscles surrounding the spine will then be dilated to allow access to the section of spine to be stabilized. After the spine is accessed, the lamina (the “roof” of the vertebra) is removed to allow visualization of the nerve roots. The facet joints, which are directly over the nerve roots, may be trimmed to give the nerve roots more room.
The nerve roots are then moved to one side and the disc material 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 incision, which typically leaves behind only a small scar or scars.
