What Is a PLIF PEEK Cage for Posterior Lumbar Interbody Fusion Surgery
A PLIF PEEK Cage is a radiolucent lumbar interbody fusion implant designed for posterior lumbar interbody fusion (PLIF) procedures. After removal of the intervertebral disc, the cage is implanted into the disc space to restore disc height, stabilize the spinal segment, and promote solid bony fusion between adjacent vertebrae.
PLIF PEEK cages are commonly used in posterior lumbar fusion surgeries in combination with pedicle screw and rod fixation systems, providing immediate mechanical stability and supporting long-term fusion.
Key Functions and Design Highlights of Radiolucent Lumbar Interbody Fusion Cage
Anatomical Footprint Design for Disc Height Restoration and Lumbar Alignment
The anatomical footprint of the PLIF PEEK cage maximizes contact with vertebral endplates, helping restore disc height and maintain lumbar alignment while distributing loads more evenly to reduce the risk of cage subsidence.
Anti-Migration Surface and Stability-Focused Geometry for Posterior Fusion
Surface serrations and stability-oriented geometry are designed to improve initial fixation and reduce the risk of cage migration under posterior loading conditions during lumbar fusion.
Large Bone Graft Window to Promote Osseointegration and Fusion Progress
The central cavity allows sufficient packing of autograft or bone substitute materials, creating an optimal fusion bed to support osseointegration and long-term fusion success.
Radiolucent PEEK Material with Imaging Compatibility for Fusion Assessment
Medical-grade PEEK material enables clear visualization on X-ray and CT imaging, allowing surgeons to monitor fusion progress without interference from metal artifacts.
Multiple Sizes and Lordotic Angles for L1–S1 Lumbar Applications
A comprehensive range of cage heights, footprints, and lordotic angles ensures compatibility with various lumbar levels and patient anatomies.
Clinical Indications and Surgical Applications of PLIF Lumbar Fusion Cage
Degenerative Disc Disease and Segmental Lumbar Instability
Spondylolisthesis and Lumbar Spinal Stenosis Requiring Fusion
Recurrent Disc Herniation After Failed Conservative Treatment
These clinical scenarios represent common indications where PLIF lumbar interbody fusion cages are selected to restore stability, decompress neural structures, and improve patient outcomes.

FAQ – PLIF PEEK Cage for Posterior Lumbar Interbody Fusion
What is a PLIF PEEK cage used for in lumbar fusion surgery?
A PLIF PEEK cage is used to restore disc height, stabilize lumbar segments, and promote bone fusion during posterior lumbar interbody fusion procedures.
What is the difference between PLIF and TLIF cages?
PLIF cages are typically implanted bilaterally through a posterior approach, while TLIF cages are inserted unilaterally through a transforaminal pathway.
Why choose a PEEK interbody cage instead of a titanium cage?
PEEK cages are radiolucent, allowing clearer post-operative imaging and fusion assessment without metal artifacts.
Can this PLIF cage be used with pedicle screw and rod systems?
Yes, the PLIF PEEK cage is designed to be used in combination with posterior pedicle screw-rod fixation systems.
What support can CZMEDITECH provide for distributors?
CZMEDITECH provides product catalogs, technical specifications, quality documentation, and OEM/private label support for global distributors.
