Stryker’s Spine division has received 510(k) clearance for its Tritanium® C Anterior Cervical Cage. It is a 3D-printed interbody fusion cage designed for the cervical spine.
The Tritanium C Anterior Cervical Cage
The Tritanium C Anterior Cervical Cage is built with Stryker’s proprietary Tritanium In-Growth Technology, precisely with the Tritanium material which is able “to wick or retain fluid”, unlike traditional titanium material.
“We are excited to introduce the Tritanium C Anterior Cervical Cage following the successful launch last year of our Tritanium Posterior Lumbar Cage,” said Bradley Paddock, President of Stryker’s Spine division. “The benefits of additive manufacturing to create highly porous spinal implants that are ‘engineered for bone’ are becoming increasingly clear. Additive manufacturing allows us to push beyond conventional manufacturing techniques to address design complexity and achieve previously unmanufacturable geometries, while delivering the performance, reproducibility, and quality our customers have come to expect.”
The structure of this material aims to bring a good environment for cell attachment and proliferation. The aim is to facilitate the implant creation using 3D Printing.
An open central graft window and lateral windows enable to reduce stiffness of the cage and minimize subsidence. The large window on the other hand allows for bone graft containment. Furthermore, the cage integrates serrations on both superior and inferior surfaces. They are intended for bidirectional fixation and to increase surface area for endplate contact with the cage.
According to experts, “Its smooth posterior edges help to facilitate insertion and protect soft tissue and anatomy. The Tritanium C Anterior Cervical Cage is offered in a number of footprints, heights, and lordotic angles to adapt to a variety of patient anatomies.”
Surgeons could expect to use the cervical cage by the end of this year, in Q4 2017.
