Corin’s Trinity™ PLUS cup mimics the structure of bone and gains 510k clearance

Fixation in poor bone, in either primary or revision situations, is a common clinical problem that requires specific solutions, until now these situations have been addressed using standard implants.
Corin have announced that the Trinity™ PLUS acetabular cup, designed to address these situations, has received 510k clearance from the FDA for sale in the USA. CE approval is expected to follow shortly.
The Trinity™ PLUS system offers surgeons a unique highly porous acetabular cup created with next generation additive manufacturing (AM) processing to deliver a fully randomised 3D structure.
Utilising highly advanced software simulations it has been possible to mimic the range of pore size in trabecular bone together with an extremely strong scratch fit.
When combined with a proprietary coating technology a unique solution is created, not only with a 3D structure but also for the first time a coating which is present throughout the network of interconnected cells and not just on the surface on the cup.
This highly porous surface is designed to increase stability and accelerate the on-growth and specifically in-growth of bone. The Trinity™ PLUS cup can be used with all existing Trinity™ bearing options and can also make use of the Trinity™ Dual Mobility solution to increase stability in both primary and revision situations.
Trinity™ PLUS will be in controlled release during 2018 with full market launch early in 2019.
