PLIF Surgical Solution

PLIF cage placement in posterior lumbar interbody fusion

Posterior Interbody Cage Placement

PLIF Product Functions

Posterior Lumbar Fusion Support

The PLIF solution is intended for posterior lumbar interbody fusion procedures in the treatment of lumbar degenerative diseases, spondylolisthesis, spinal stenosis, instability and selected deformities.

The PLIF PEEK Cage features a large graft window, bone-like elastic modulus and radiopaque markers designed to support fusion, maintain intervertebral height and restore physiological spinal alignment. Used with dedicated insertion instruments and posterior pedicle screw fixation, the system supports accurate implantation and immediate segmental stability.

Anatomical Design

Cage geometry is designed to support intervertebral positioning and disc-height restoration.

Secure Implant Stability

Posterior screw-and-rod fixation supports reliable segmental stabilization.

Radiolucent PEEK Material

PEEK construction supports postoperative imaging assessment with visible radiopaque markers.

Mechanical Support

The implant and instrument combination supports controlled cage placement and construct fixation.

PLIF Surgical Procedure

Posterior Lumbar Interbody Fusion

The PLIF procedure provides direct posterior decompression and interbody fusion to restore spinal stability, relieve neural compression, restore disc height and support long-term fusion with posterior fixation.

01

Posterior Lumbar Exposure

A posterior midline approach is performed to expose the affected lumbar segments. The paraspinal muscles are carefully retracted to provide clear visualization while preserving the surrounding soft tissues.

02

Pedicle Screw Placement

Pedicle screws are accurately inserted into the vertebrae under fluoroscopic guidance. The screws establish a stable posterior foundation for interbody fusion and final construct fixation.

03

Bilateral Neural Decompression

A laminectomy and bilateral facetectomy are performed to decompress the neural structures. The affected intervertebral disc is accessed through the posterior approach while relieving pressure on the spinal canal and nerve roots.

04

Discectomy and Cage Insertion

The degenerated disc is removed and the endplates are prepared for fusion. Bone graft material and an interbody cage are inserted into the disc space to restore disc height and promote solid fusion.

05

Rod Fixation and Verification

The rods are connected to the pedicle screws and securely tightened to restore spinal stability. Final fluoroscopic verification confirms implant position, alignment and overall fixation before wound closure.

Integrated PLIF Workflow

Posterior decompression, cage insertion and pedicle screw fixation are coordinated as one lumbar fusion workflow.

PLIF Procedure Advantages

Reliable Posterior Fusion Workflow

The solution integrates posterior decompression, interbody support and rigid posterior fixation within one coordinated surgical system.

01

Direct Neural Decompression

The posterior approach provides direct access to the affected spinal canal, nerve roots and intervertebral disc.

02

Disc Height Restoration

The PLIF cage supports restoration of intervertebral height and physiological lumbar alignment.

03

Posterior Segmental Stability

Pedicle screws and connecting rods provide stable posterior fixation for the treated lumbar segment.

04

Fusion Support

The cage graft chamber provides space for bone graft material to support the lumbar fusion process.

05

Instrument Compatibility

Dedicated cage insertion and posterior fixation instruments support an efficient, coordinated surgical workflow.

06

Complete System Supply

Implants, instruments and compatible configurations can be supplied together according to distributor or hospital requirements.
