Constructed to wick4

Tritanium Through-Growth Technology with porcine bone marrow aspirate*

This in-vitro study demonstrated that a cube built with Tritanium material was able to wick fluid into the porous structure under specified conditions.4

It also absorbed and held fluid inside the porous structure.4

More BMA absorption than allograft and PEEK5

The Tritanium C Cage demonstrated it absorbed 3 times more bone marrow aspirate (BMA) than allograft and 4 times more BMA than PEEK, in an in vitro study.5

allograft

*This experiment was performed using heparinized porcine bone marrow aspirate. No correlation to human clinical outcomes has been demonstrated or established.

Designed to create a favorable environment for cells2,3

A coupon built with Tritanium Through-Growth Technology demonstrated that osteoblasts (bone cells) infiltrated, attached to and proliferated on the porosity of the Tritanium technology2. The unique porous structure is designed to create a favorable environment for cell attachment and proliferation2,3.

Developed to minimize subsidence1

Developed to minimize subsidence1

The Tritanium PL Cage demonstrated better resistance to subsidence than other commercially available posterior lumbar interbody cages constructed out of different materials, including those with a larger footprint.1

  • Porous Tritanium has an elastic modulus that falls between cancellous and cortical bone1

  • Large central graft and lateral windows help to reducethe overall stiffness of the cage and allow room for bone graft to be packed inside the cage1

  • Teeth are designed to increase the surface area of the device in contact with bone in order to help normalize load transmission and minimize subsidence1

Created to allow imaging

With large lateral windows, Tritanium PL allows visualization on CT and X-ray.

The AMagine Institute is the world’s largest additive manufacturing facilityfor orthopaedic implants.

AMagine is Stryker’s proprietary approach to implant creation using additive manufacturing (AM). Additive manufacturing allows us to push beyond conventional manufacturing techniques to address design complexity and achieve previously unmanufacturable geometries, but also to deliver the performance, reproducibility and quality you expect from our products.

Stryker’s investment in additive manufacturing began in 2001 and, since then, Stryker has collaborated with leading universities in Ireland and the UK to industrialize 3D printing for the healthcare industry.

The AMagine Institute, Stryker’s new global technology development center/hub located in Cork, Ireland, is the world’s largest additive manufacturing facility for orthopaedic implants. Among the most advanced AM facilities of its kind, it is where bright ideas are transformed into exciting new implants, for use in spinal surgery.

AMagine, which incorporates hundreds of quality checks per batch, enables us to design and build the Tritanium PL and C Cages with pinpoint precision, optimizing every property of the device, from pore size and porosity to shape and surgical features.1

Originally launched for hip and knee implants, Stryker’s Tritanium technology has been proven in over 10 years of clinical experience with more than 300,000 orthopedic devices implanted.1

Anterior Placement
System

Anterior Placement
System


Tritanium TL's Anterior Placement System and cage design combine to enable the surgeon's desired apophyseal placement.


Shaped for steerability

Tritanium TL's unique,curved shape and rounded teeth are designed to provide tactile feedback and maximize apophyseal bone contact.


Designed for versatility

Offering two inserter and two tamp options, our system is designed for versatility and procedural flexibility, allowing placement in open and MIS procedures.

  • The low-profile, fully-threaded Steerable Inserter allows the cage to be locked at different angles and allows for intradiscal visualization of the cage as it is impacted and rotated to the surgeon's desired placement

  • The low-profile, fully-threaded static Straight Inserter provides a simplified and straightforward option for cage insertion

  • The Saddle and Half Saddle Tamps directly mate with the implant for minor final adjustments to the cage's placement


Created for tactile control


  • Tritanium TL's Steerable Inserter is equipped with a friction lock that allows simple, in-line insertion and rotation into the disc space, enabling visualization during MIS TLIF procedures

  • With a unique, curved shape and a roughened Tritanium surface with multidirectional teeth, the cage is designed to provide tactile feedback while it is steered to its desired placement
