TLIF / PLIF
Transforaminal and posterior lumbar interbody fusion — approaches the disc space from the back to decompress nerves and stabilize selected levels.
What it is
TLIF and PLIF approach the lumbar disc space from the back. Through a posterior exposure, Dr. Choi decompresses the nerves, removes the damaged disc, places an interbody implant, and adds screws and rods to stabilize the level. The two techniques differ in the exact window used to reach the disc space and how much facet joint is removed.
These are workhorse fusion procedures: the posterior approach allows direct, thorough nerve decompression at the same time as stabilization, which makes them well suited to cases where both are needed.
When it may be considered
TLIF or PLIF may be considered when instability, deformity, disc collapse, or nerve compression requires both decompression and fusion. This includes spondylolisthesis, recurrent disc herniation with instability, and selected cases of stenosis with instability. The choice between techniques depends on anatomy, prior surgery, the side of symptoms, and the goals of reconstruction.
What to discuss at consultation
- Goals: take pressure off the nerves, stabilize the level, and correct the structural problem causing symptoms.
- Alternatives: nonoperative care, decompression alone, or another fusion approach such as ALIF or LLIF.
- Recovery: a brace is generally not required after posterior lumbar fusion; activity progresses as the fusion heals.
- Risks: fusion, adjacent-level changes over time, and the individual risks of surgery — discussed before any decision.
Initial consultation or second opinion?
Bring your imaging and your questions. Dr. Choi will review your diagnosis, walk through your options, and tell you plainly whether surgery is the right next step — and if not, what is.
