About


The next generation of fit and fill stem philosophy.

Anatomically designed

Anatomically designed


Fit and fill stems aim to achieve early fixation by completely filling the metaphyseal canal and circumferentially engaging the proximal femoral cortex.

The TriFit CF stem is anatomically designed based on extensive 3D analysis of 250 global CT scans1 to create an optimal proximally filling stem suitable for most patient femur types.

Stability

Stability


Optimised mid-length stem and stem geometry in A/P and M/L plane is designed to ensure effective proximal stability providing maximum engagement in the metaphysis.

The TriFit CF is plasma spray coated proximally and is designed to provide a rough surface to achieve a consistent press-fit which is important for stability.

Secondary stability is achieved with Corin’s Biomimetic Cementless Technology coating of calcium phosphate (CaP) with a microcrystalline structure to promote osseointegration and encourage long term biological stability 2,3,4.

 

Versatility

Versatility


Direct Anterior friendly for minimally invasive surgical approaches for anatomy preservation. The TriFit CF is compatible with Trinity™ advanced bearings.

TriFit CF is part of the TriFit family which offers flexibility intraoperatively thanks to the 'one instrument' platform concept.
