ostaPek® carbon composite technology

Biological Potential

Carbon composite spine implants show five times more cell growth compared to PEEK [Barbanti Brodano, 2007]. Human osseous cells are distributed continuously and homogeneously on the carbon composite implant surfaces compared to multi-layered discontinuous cell clusters on PEEK.

Carbon-fiber-reinforced composite osseointegration in terms of percent bone area for distances from the implant surface of 0.1mm is four times higher compared to Titanium [Petersen, 2016]. Moreover, carbon composite implants show significantly improved results in terms of cellular density and viability compared to Titanium surfaces [Sigot-Luizard, 2000].

Smart Structural Design

ostaPek® spine cages are designed to maximise space for bone graft without compromising mechanical strength.

This is possible by engineering specific fiber patterns that follow the direction of the longitudinal forces similar to the trabeculae in the adjacent vertebral bodies.

Stability & Stimulation

ostaPek® carbon composite cages and plates meet the mechanical requirements to ensure primary stability and strength throughout the bone fusion mass development.

At the same time, the stiffness of ostaPek® constructs is designed to provide an active stimulation of the bone cells during the development of the bone fusion mass.

Radiolucency

The ostaPek® carbon composite material is radiolucent and therefore allows for clear post-operative radiological visual assessment and treatment.

67% of the ostaPek® carbon composite material are long, oriented carbon fibers embedded in a 33% PEKEKK matrix.

PEKEKK has a noticeably higher strength level and overall stability compared to PEEK.

Development & Production

ostaPek® carbon composite has been developed in the USA and is manufactured in Switzerland.
