Smith+Nephew (NYSE: SNN)+ announced today that it launched its OR3O dual mobility system for hip arthroplasty in India.
The London-based orthopedic device maker designed OR3O for use in primary and revision hip arthroplasty. Compared to traditional solutions, dual mobility implants have a smaller-diameter femoral head. It locks into a larger polyethylene insert, increasing stability, reducing dislocation risk, and improving range of motion.
Smith+Nephew initially launched OR3O in the U.S. in 2020.
While most hip implants utilize a cobalt chrome (CoCr) liner with CoCr/SST or ceramic head balls, OR3O uses a different bearing surface. The system utilizes Smith+Nephew’s advanced Oxinium DH for its liner and proprietary Oxinium on XLPE for its femoral head and polyethylene inserts. This eliminates the modular CoCr liner and/or CoCr head ball from the construct. Smith+Nephew said this reduces wear and corrosion risks associated with the alloy.
The company said it made the system available for both primary and revision applications in India. It offers cross-compatibility with the R3 Acetabular system.
“Smith+Nephew’s OR3O dual mobility system is a groundbreaking introduction for India that offers technology not available in other systems,” said Joaquin Lasso, managing director, South Asia, Smith+Nephew. “Over a dozen peer-reviewed publications have now cited or expressed concerns over corrosion or elevated ions in CoCr modular dual mobility liners. The reduced corrosion of our Oxinium and Oxinium DH bearing surface sets OR3O apart from the competition.”
