Corin Launches Trinity™ Dual Mobility Hip Replacement System at AAOS 2018

UK based Corin, a global orthopaedic player, has chosen the American Academy of Orthopaedic Surgeons (AAOS) 2018 Annual Meeting in New Orleans at which to announce the launch of its Trinity™ Dual Mobility System.


Boasting new implant technology, Trinity is designed to improve range of motion and reduce the risk for instability and dislocation after primary or revision hip replacement. The system is intended for use with Corin’s Optimized Positioning System (OPS™). OPS is an innovative technology that helps surgeons determine the best positioning and orientation of a hip implant based on a dynamic preoperative functional assessment and analysis of each patient.

The Trinity Dual Mobility System is a modular acetabular system that puts two articulating surfaces in the same joint space to provide patients with increased stability, multi-directional movement and a greater range of motion compared to conventional hip replacement.

The system is manufactured using Corin’s ECIMA™ polyethylene to help reduce the risk of in-vivo oxidation. Its proprietary design allows for a self-centering of the polyethylene liner during normal gait cycles, which reduces load and eliminates the risk of impingement between stem and polyethylene. Also, surgeons have the ability to orient the liner and decide the location of the elevated portion of the lip for an increase in jump height and greater range of motion.

Physician comments

“Dual mobility systems have emerged to better address instability and dislocation after total hip replacement,” said orthopaedic surgeon Douglas Dennis, MD of Colorado Joint Replacement in Denver, and a paid consultant to Corin. “The Trinity Dual Mobility System, when used with OPS technology, may go even further in addressing these issues by helping surgeons achieve optimal functional implant positioning, which has a significant impact on patient outcomes.”

“Dual mobility and optimized functional positioning is a powerful combination that will help me better tailor the operation to the patient and improve outcomes,” said Stephen Raterman, MD, an orthopedic surgeon at Florida Hospital in Tampa and a paid consultant to Corin.

Company comments

“We continue to respond to the needs of orthopaedic surgeons and their patients with clinically-proven procedural solutions that may help improve outcomes and increase patient satisfaction,” said Paul Berman, President, Corin USA.
