Product Description
The PLIF design is optimized for paired insertion, providing balanced, bilateral support that effectively resists rotational forces and maintains lumbar disc height across the entire motion segment.
Constructed from PEEK-OPTIMA®, the cage shares physiological loads with the bone graft, stimulating osteoblastic activity and reducing the likelihood of implant-related bone resorption.
Equipped with a sophisticated serrated surface, the cage bites into the vertebral endplates upon insertion, providing immediate primary stability and preventing cage migration or retropulsion into the spinal canal.
The PEEK body is transparent to X-rays, allowing surgeons to monitor the formation of the internal bone bridge, while tantalum pins provide clear markers for confirming exact implant depth.
Indicated for the treatment of Grade I or II slips in the lumbar spine. The PLIF cage is used to reduce the translation between vertebrae and provide the rigid anterior column support needed to stop further slip progression.
Applied in cases where the intervertebral disc has significantly collapsed, leading to mechanical back pain. The cage restores the anatomical space, tensioning the surrounding ligaments for immediate segmental stability.
Used to address nerve root compression. By increasing the vertical height of the disc space, the PLIF cage effectively enlarges the neural foramen, providing indirect decompression and relief from radicular leg pain.
Specifically indicated for revision cases where a previous discectomy has failed. The PLIF approach allows for wide decompression and the insertion of a structural cage to ensure a permanent biological fusion.

The PLIF Peek Cage is a high-performance interbody spacer designed for Posterior Lumbar Interbody Fusion procedures. It is crafted from PEEK-OPTIMA®, a medical polymer that provides structural integrity while mimicking the flexibility of human bone. Unlike single-cage systems, PLIF cages are typically implanted as a pair—one on each side of the spinal canal—to provide comprehensive support and maximize the surface area for bone graft and eventual fusion.
This cage is applied in lumbar spinal surgery to treat conditions such as degenerative disc disease and spondylolisthesis. It is inserted through a posterior approach following a laminectomy or discectomy. By placing two cages within the disc space, surgeons can restore the anatomical height of the lumbar segment, decompress pinched nerves, and stabilize the anterior column of the spine.
The primary advantage of the TOOLMED PLIF Cage is its anatomical design which provides exceptional primary stability. Its radiolucent nature ensures that surgeons can easily monitor the progress of the fusion mass without the interference of metal artifacts on X-rays or CT scans. Furthermore, the material properties of PEEK help prevent the cage from sinking into the vertebral endplates (subsidence), ensuring long-term maintenance of disc height.
Biomechanically, the PLIF cage acts as a load-sharing device that converts axial compression into a stimulus for bone growth. Its biconvex shape ensures a flush fit against the natural curvature of the lumbar endplates, while its aggressive serrations provide high resistance to rotational and shear forces. This dual-cage configuration creates a stable mechanical environment that is essential for a solid biological union.
Through a posterior incision, the surgeon performs a bilateral laminectomy and removes the disc material. After preparing the endplates, trial spacers are used to determine the perfect cage height. The PLIF Peek Cages are then packed with bone graft and inserted symmetrically on either side of the dura. Tantalum markers allow for intraoperative verification of position, and the procedure is typically completed with posterior pedicle screw fixation.
Postoperative care includes a gradual mobilization plan, often supported by a lumbar brace to restrict excessive trunk rotation during the early healing phase. Patients are monitored with periodic radiographic imaging to observe the "fusion window" within the cage. Because PEEK is MRI-safe, high-resolution imaging can be performed if needed to assess neural decompression postoperatively.
The TOOLMED PLIF Peek Cage provides a structurally superior and biologically compatible option for lumbar fusion. Its anatomical design and high-grade PEEK construction make it a trusted choice for surgeons aiming to restore spinal function and alleviate pain in patients with chronic lumbar instability.
Using two cages (one on each side) provides more balanced support and a larger surface area for fusion compared to a single cage, which is particularly important in the high-stress lumbar environment.
The PEEK material is radiolucent (invisible), but our cages include tantalum markers that appear as clear dots on X-rays, allowing the surgeon to confirm the cage is perfectly positioned.
While specifically designed for a posterior (PLIF) approach, the dimensions may allow for TLIF use in certain cases; however, we recommend our specialized TLIF cages for transforaminal approaches due to their tapered leading edge.
The cage is supplied sterile and empty. It is designed with a large central window that the surgeon packs with bone graft material during the surgery.
