Expandable Posterior Lumbar Titanium Cage

Product Overview

The CZMEDITECH Expandable Posterior Lumbar Titanium Cage is designed for posterior lumbar interbody fusion procedures, including PLIF (Posterior Lumbar Interbody Fusion) and TLIF (Transforaminal Lumbar Interbody Fusion). The implant provides controlled in-situ expansion to help restore disc height, maintain foraminal height, and support sagittal alignment while minimizing insertion footprint.

Manufactured from medical-grade titanium alloy, the cage features a porous surface structure that promotes osseointegration and long-term fusion stability. The expandable design allows surgeons to insert the implant through a smaller surgical corridor and then expand it to achieve optimal endplate contact and load distribution.

Designed for spine surgeons seeking reliable fixation and fusion outcomes, the system combines biomechanical strength, radiographic visibility, and procedural efficiency.

Application

The Expandable Posterior Lumbar Titanium Cage is indicated for:

• Degenerative Disc Disease (DDD)

• Lumbar Spinal Stenosis

• Spondylolisthesis

• Recurrent Disc Herniation

• Lumbar Segmental Instability

• Post-Discectomy Reconstruction

• Revision Lumbar Fusion Procedures

• PLIF Procedures

• TLIF Procedures

Key Features

Controlled In-Situ Expansion

The cage can be expanded after insertion, allowing restoration of intervertebral disc height while minimizing neural tissue retraction.

Optimized Endplate Contact

Expansion increases the implant footprint, helping distribute loads evenly and reduce the risk of subsidence.

Titanium Alloy Construction

Manufactured from Ti6Al4V medical-grade titanium alloy for excellent strength, corrosion resistance, and biocompatibility.

Porous Surface Technology

Engineered surface promotes bone ongrowth and enhances biological fixation.

Restoration of Sagittal Alignment

Supports lumbar lordosis restoration and spinal balance reconstruction.

Minimally Invasive Compatible

Designed to facilitate MIS-TLIF and other minimally invasive lumbar fusion procedures.

Enhanced Initial Stability

Provides immediate mechanical support during the fusion process.

Large Bone Graft Chamber

Allows sufficient bone graft packing to encourage fusion development.

Technical Specifications

Benefits for Surgeons

Easier Implant Insertion

A reduced insertion profile helps facilitate placement through limited surgical corridors.

Disc Height Restoration

Expansion enables restoration of intervertebral height after implantation.

Improved Foraminal Decompression

Indirect decompression may be achieved through restoration of disc and foraminal height.

Enhanced Fusion Environment

Large graft chamber and porous surface support biological fusion.

Reduced Endplate Stress

Expanded footprint helps distribute loads over a larger contact area.

FAQ

1. What is an expandable posterior lumbar titanium cage?

An expandable posterior lumbar titanium cage is an interbody fusion implant inserted in a collapsed state and expanded after placement to restore disc height and provide spinal stability.

2. What procedures is this cage used for?

The cage is primarily used in PLIF and TLIF lumbar fusion surgeries.

3. What material is used?

The implant is manufactured from medical-grade Ti6Al4V titanium alloy.

4. Why choose an expandable cage instead of a static cage?

Expandable cages allow smaller insertion profiles while enabling restoration of disc height and larger endplate contact after expansion.

5. Does the cage support bone fusion?

Yes. The implant includes a large graft chamber and porous surface designed to support osseointegration and fusion.

6. Can the cage be used in minimally invasive surgery?

Yes. The system is designed to support MIS-TLIF and other minimally invasive lumbar fusion techniques.

7. What conditions can be treated with this cage?

Degenerative disc disease, spinal stenosis, spondylolisthesis, recurrent disc herniation, and lumbar instability.

8. Is the implant MRI compatible?

The titanium alloy construction is generally MRI conditional. Users should follow local MRI safety guidelines.

9. Is OEM branding available?

Yes. CZMEDITECH provides OEM and ODM services for qualified distributors.
