Cohere™ XLIF™
Product Overview
Cohere™ XLIF™ is a lateral porous PEEK implant designed to promote bone ingrowth1 while maintaining the inherent biomechanical1 and imaging properties of PEEK.
Features and Benefits
Porous Surface
As demonstrated in animal testing, porous endplates are designed to promote new bone ongrowth and ingrowth,1 leading to greater integration strength than smooth PEEK.2,3
Durable Structure
Designed to mimic the architecture and stiffness of bone, maintain high porosity under conditions that replicate anatomic loading, and resist abrasion damage and delamination under impacted insertion.4,5
Created with Imaging in Mind
Leverages the radiolucent properties of PEEK to enable radiographic visualization on a variety of imaging modalities.
