Cohere™ Cervical
Product Overview
Cohere™ Cervical is a porous PEEK implant designed to promote bone ingrowth1 while maintaining the inherent biomechanical1 and imaging properties of PEEK, for anterior cervical discectomy and fusion.
Features and Benefits
Porous Surface Designed to Participate in Fusion
Supports bone ingrowth in animal models with integration strength exceeding that of smooth PEEK and titanium plasma spray on PEEK.1-3
Durable Structure
With a stiffness similar to bone, Cohere™ Cervical implants were shown to reduce stress shielding and risk of subsidence, compared with solid titanium implants in biomechanical testing.4
Created with Imaging in Mind
Leverages the radiolucent properties of PEEK to enable radiographic visualization on a variety of imaging modalities.
