Transforaminal Lumbar Interbody Fusion (TLIF)
A Transforaminal Lumbar Interbody Fusion (TLIF) is a surgical procedure designed to address conditions such as degenerative disc disease, spondylolisthesis, or spinal stenosis in the lumbar spine. This procedure involves accessing the spine through the back, specifically through the intervertebral foramen, the opening through which nerve roots exit the spinal canal.
During a TLIF procedure, an incision is made in the lower back, providing access to the lumbar spine. The damaged disc is removed, and a device is placed in the intervertebral space to promote fusion between the adjacent vertebrae.The intervertebral body device also helps restore height to the foramen and can restore alignment of the spine.
This device encourages the growth of new bone and stabilizes the spine. One notable aspect of TLIF is its approach through the foramen, allowing for decompression of the nerves, which can be particularly beneficial when there is nerve compression. Additionally, spinal instrumentation such as screws and rods are used to provide stability during the fusion process. TLIF aims to alleviate pain, restore spinal stability, and promote fusion between vertebrae. The procedure is tailored to each patient’s specific condition, and the decision to undergo TLIF is typically made after conservative treatments have proven ineffective.

Conditions Related To TLIF
Scoliosis
A scoliosis curve can occur in the thoracic spine, the lumbar spine, or both areas at the same time.
Piriformis Syndrome
Piriformis syndrome occurs when the piriformis muscle, which runs from the lower spine to the top of the thigh bone, presses on the sciatic nerve.
Sciatica
The term sciatica refers to a type of radiculopathy, a pinching or compression of a nerve that occurs in the leg.
SI Joint Dysfunction
The sacroiliac (SI) joints are located where the sacrum (the triangular bone at the base of the spine) meets the iliac bones (the large pelvic bones).
Lumbar Stenosis
Spinal stenosis describes narrowing inside the spinal canal and mainly occurs from a combination of aging and degenerative changes in the spine.
