As spinal surgery technology continues to evolve, 3D printed titanium cages are becoming one of the most important innovations in modern spinal fusion procedures. Compared with traditional spinal implants, 3D printed cages provide improved osseointegration, optimized biomechanical performance, and enhanced long-term stability.
Today, many spine surgeons are transitioning from conventional PEEK or solid titanium implants to porous titanium interbody cages designed with advanced 3D printing technology.
The Trauhui Medical Coales 3D Printed Cage System was developed to meet the growing demand for high-performance spinal fusion implants for cervical and lumbar procedures.

A 3D printed cage is an interbody fusion implant manufactured using additive manufacturing technology, typically with porous titanium alloy materials. These implants are designed to stabilize the spine, restore disc height, and create an ideal environment for bone fusion.
Unlike conventional cages, a 3D printed titanium cage can mimic the structure of cancellous bone through a porous trabecular design. This helps encourage natural bone ingrowth and long-term biological fixation.
During spinal fusion surgery, the cage is inserted into the intervertebral disc space after disc removal. Bone graft material is then placed around or inside the implant to promote fusion between adjacent vertebrae.
The porous architecture of the implant allows bone cells to grow into the cage surface, improving implant stability over time.
Restore disc height
Stabilize the spinal segment
Promote osseointegration
Support long-term fusion
Maintain spinal alignment
Many surgeons prefer 3D printed titanium cages because they combine mechanical strength with biological advantages.
One of the biggest benefits of porous titanium implants is improved osseointegration.
The Coales system features a trabecular structure with approximately:
30% porosity
300μm pore size
This structure closely resembles cancellous bone and supports stronger bone ingrowth.
Successful spinal fusion depends on achieving stable biological fixation between vertebrae. Better osseointegration may help:
Improve fusion rates
Reduce implant loosening
Enhance long-term stability
Support faster healing
Traditional solid titanium implants can sometimes create stress shielding because they are significantly stiffer than bone.
The Coales 3D Printed Cage System is designed with a modulus of elasticity closer to cancellous bone, helping distribute load more naturally across the fusion segment.
Reduced risk of bone resorption
Improved load sharing
Better biomechanical balance
Enhanced fusion environment
Initial implant fixation is critical in spinal fusion procedures.
The porous titanium surface of the cage increases friction against vertebral endplates, helping provide strong immediate stability after implantation.
The Coales system also includes:
Self-drilling screws
Self-tapping screws
Integrated locking mechanisms
These features help improve fixation security and simplify surgical workflow.
3D printed interbody cages are widely used in both cervical and lumbar spinal fusion procedures.
The Coales-C and Coales-AC systems are designed for cervical procedures such as:
ACDF surgery
Cervical degenerative disc disease
Cervical instability
Cervical disc collapse
The Coales-AC implant features a zero profile design, which may help:
Reduce postoperative dysphagia
Minimize soft tissue irritation
Reduce adjacent level ossification
The Coales-T, Coales-P, Coales-L, and Coales-XL systems are designed for lumbar fusion procedures, including:
TLIF
PLIF
LLIF/XLIF
OLIF
These cages could be used for:
Degenerative lumbar disease
Lumbar instability
Revision spine surgery
The implants are anatomically shaped to better match the intervertebral space and help restore lumbar lordosis.
Available footprints and lordotic angles allow surgeons to select the most appropriate implant based on patient anatomy.
As spinal fusion technology advances, surgeons increasingly prioritize implants that improve both biological and mechanical performance.
Compared with traditional cages, porous titanium implants may provide:
Better bone integration
Improved fusion potential
Stronger initial fixation
Enhanced imaging visualization
Long-term implant stability
The Coales system is designed for excellent postoperative visualization with reduced imaging interference, helping surgeons evaluate fusion progression more clearly.
Selecting the appropriate interbody cage depends on several factors.
TLIF
PLIF
LLIF/XLIF
OLIF
Disc height
Endplate shape
Bone quality
Porosity
Material composition
Cage footprint
Lordotic angle
The Coales product portfolio includes multiple cage sizes, footprints, and angles to support different surgical requirements.
The demand for 3D printed spinal implants continues to grow worldwide as hospitals and surgeons seek advanced solutions for spinal reconstruction.
3D printing technology allows manufacturers to create implants with:
Complex porous structures
Customized biomechanical properties
Improved biological fixation
Enhanced implant precision
As technology continues to advance, 3D printed cages are expected to become increasingly important in modern spine surgery.
