Posterior Lumbar Interbody Fusion (PLIF) is a common form of surgery that can effectively provide relief from enduring or debilitating pain in the lower back, known as the lumbar region. PLIF is performed by gaining access to the spine through the patient’s back (posterior approach), which may be advantageous because it avoids many organs and major blood vessels in the abdominal region and offers direct access close to the affected site.
At Princeton Neurological Surgery, patients are evaluated by a neurosurgical team led by Dr. Edward H. Scheid, Jr., a board-certified neurosurgeon with more than 6,000 successful spine surgeries. Our team uses a step-by-step approach supported by detailed imaging to identify the true source of pain and determine whether fusion is appropriate. Patients in Hamilton and Jersey City, NJ trust our practice for individualized care designed to restore stability, relieve nerve compression, and improve long-term function.
What is Posterior Lumbar Interbody Fusion?
An interbody fusion technique involves removing an intervertebrael disc, inserting a bone spacer to maintain disc height, and fusing the vertebraee on either side together. PLIF is often a successful treatment method for numerous lower back problems, such as spondylolisthesis and disc space collapse, that have not responded to conservative therapies.
Prior to the procedure, detailed images of the spine may be produced using MRI and CT scans. This allows the team to pinpoint the exact location of the problem in the spine as well as establish the most appropriate type of implant for correction.
The Benefits Of PLIF Surgery
By entering through the patient’s back, posterior lumbar interbody fusion may offer these advantages:
- More direct exposure of the vertebraee to remove disc material and decompress neurologic pathways
- Larger surface area for bone graft healing, which can support successful fusion
- Avoidance of many abdominal organs and major blood vessels that may be encountered with anterior approaches
- High success rates, commonly reported in the 90–95% range
Who is a Candidate for PLIF Surgery?
PLIF may be recommended when a patient has ongoing serious back pain that has not responded to conservative treatment options. It is used to correct a variety of spine problems, including degenerative disc disease, disc herniation, spinal stenosis, scoliosis, and spondylolisthesis.
The goal of this surgery is to decrease chronic pain, correct spinal deformity when present, and eliminate movement between the two fused vertebraee. These procedures are commonly performed on the L4-L5 vertebraee or the L5-S1 segment at the bottom of the lumbar spine.
The PLIF Surgery Procedure
PLIF is performed under general anesthesia with the patient positioned lying face down. An incision is made in the midline of the back near the affected portion of the spine, and tools are used to separate and retract the muscles. Imaging helps ensure that the precise vertebraee are targeted. Next, the lamina may be removed and excess bone trimmed back to obtain an unobstructed view of the nerve roots. The injured disc, bone spurs, and any existing fragments are then removed to restore room for nerves that have been compressed.
To fill the space created, a bone graft or bone morphogenetic proteins (BMP) may be placed in the open disc area, and instrumentation is affixed as needed to maintain stability. The hardware often includes spacers containing graft material and may include rods and screws to hold the spinal bones in place while fusion occurs. Imaging is used again to confirm placement before the incision is closed.
Recovery After PLIF Surgery
Patients typically remain in the hospital for three to five days. Physical therapy may begin shortly after surgery to help restore strength and mobility.
Activities such as lifting, twisting, and bending are restricted during early recovery. Many patients return to non-strenuous work within two to three weeks, while more rigorous activity may resume after several months depending on healing.
Fusion generally takes three to six months to solidify. While discomfort is expected initially, the most significant pain typically improves within the first few weeks, with continued gradual improvement as healing progresses.
Risks And Considerations
PLIF is considered a safe procedure, but as with any spinal surgery it carries risks. The most frequent complication is nonunion, meaning the bones do not fuse properly, which may require another procedure. This is more likely in patients who smoke, are obese, have had prior spine surgery, or have undergone radiation treatments. Other uncommon risks include persistent pain, infection, and bleeding.
