What Are Interbody Fusion Cages
Structure and Function of Spinal Interbody Cages
Interbody fusion cages are implantable devices placed between adjacent vertebral bodies during spinal fusion surgery. They are designed to replace damaged disc space and provide mechanical support while bone fusion develops.
A typical interbody cage design includes a hollow internal structure that allows placement of bone graft material, an external surface optimized for stability, and radiopaque markers that assist imaging evaluation after implantation.
| Design Feature | Purpose |
| Central graft window | Provides space for bone graft materials during fusion procedures. |
| Anatomical footprint design | Helps distribute loads across the vertebral endplates. |
| Textured or porous surface | Supports bone integration at the implant interface. |
| Radiopaque markers | Allow visualization of cage position during imaging. |
Role of Interbody Fusion Cages in Spine Surgery
During spinal fusion procedures, the cage functions as a structural spacer between vertebrae. It helps restore disc height, maintain alignment, and provide support while fusion occurs.
Different surgical techniques require different cage geometries. For example, cervical cages are designed for smaller anatomical spaces, while lumbar cages require larger footprints and different insertion angles.
XC Medico develops spinal implant solutions covering multiple fusion approaches, including:
Types of Interbody Fusion Cages
Interbody fusion cages are categorized according to anatomical location, surgical approach, material selection, and implant design. Understanding these differences helps hospitals and distributors select suitable product portfolios.
Cervical Interbody Fusion Cages
Cervical cages are commonly used in ACDF procedures where disc height restoration and cervical stabilization are required. These cages are designed to restore cervical disc height and provide stabilization between cervical vertebrae.
| Feature | Cervical Cage Characteristics |
| Primary application | Anterior cervical fusion procedures |
| Common material | PEEK or titanium alloy |
| Design focus | Compact footprint and anatomical fit |
TLIF Interbody Fusion Cages
TLIF cages are designed for transforaminal lumbar interbody fusion procedures. The cage is inserted through a posterior-lateral approach and supports lumbar segment stabilization.
Modern TLIF cages often include angled profiles, optimized footprints, and insertion features designed for minimally invasive spine surgery workflows. For surgeons and distributors evaluating TLIF surgical solutions the cage design should match the requirements of transforaminal lumbar interbody fusion procedures.
PLIF Interbody Fusion Cages
PLIF cages are used in posterior lumbar interbody fusion procedures. These cages are inserted from a posterior approach and are designed to restore lumbar disc height while supporting fusion.
XC Medico provides PLIF surgical solutions with compatible lumbar interbody cage systems.
ALIF Interbody Fusion Cages
ALIF cages are designed for anterior lumbar interbody fusion procedures. Their larger footprint helps address lumbar alignment requirements and provides support across the disc space. ALIF procedures often require larger footprint cages designed for anterior lumbar access.
OLIF Interbody Fusion Cages
OLIF cages are developed for oblique lumbar interbody fusion procedures. These cages typically feature larger footprints and designs suitable for lateral access techniques. OLIF fusion solutions use specialized cage designs for lateral access approaches.
PEEK vs Titanium Interbody Fusion Cages
Material selection is one of the most important considerations in spinal cage manufacturing. PEEK and titanium are widely used because they provide different mechanical and imaging characteristics.
| Material | Characteristics | Common Applications |
| PEEK | Radiolucent material with elastic properties similar to bone | Cervical cages, TLIF cages, PLIF cages |
| Titanium alloy | High strength and excellent mechanical stability | Expandable cages and structural support applications |
| PEEK with titanium coating | Combines imaging advantages with surface modification technology | Advanced spinal fusion applications |
Advantages of PEEK Cage Manufacturing
Radiolucent properties allow clearer postoperative imaging evaluation.
Elastic modulus closer to bone compared with traditional metals.
Suitable for different lumbar and cervical fusion cage designs.

Advanced Design Features of Modern Interbody Fusion Cages
The development of interbody fusion cages has moved beyond basic structural support. Modern spinal cage designs focus on improving implant stability, optimizing bone integration, and supporting different surgical approaches.
Cage Footprint and Anatomical Design
The footprint of an interbody cage directly affects load distribution between the implant and vertebral endplates. Larger footprints are often designed for lumbar applications where higher mechanical demands exist.
Modern cage manufacturers optimize implant geometry according to spinal anatomy, including:
Different widths and heights for various patient anatomies.
Angled profiles for specific insertion approaches.
Anatomical shapes designed to restore spinal alignment.
Multiple size options for surgeon selection.
Surface Technology and Bone Integration
Surface design is an important factor in spinal cage manufacturing. Different surface structures are developed to improve contact between the implant and surrounding bone.
| Surface Technology | Characteristics | Application Value |
