Corin has launched Trinity dual mobility system for hip replacement at the American Academy of Orthopaedic Surgeons (AAOS) 2018 annual meeting.

The system features new implant technology designed to improve range of motion and reduce the risk for instability and dislocation after primary or revision hip replacement. 

The system is designed for use with Corin's Optimized Positioning System (OPS), 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

Corin USA president Paul Berman said: "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.”

Corin is a European orthopaedic manufacturer based in the UK that markets its products throughout the world.
