Smith+Nephew Introduces OR3O Dual Mobility System for Hip Arthroplasty in India

Clinical studies indicate that dual mobility technology is particularly effective in managing dislocation, surpassing metal-on-metal or ceramic-on-ceramic large head series.

Smith+Nephew, a UK-based medical technology firm, has unveiled the OR3O Dual Mobility System, designed for primary and revision hip arthroplasty in India.

This system introduces a novel approach to hip implants, utilising dual mobility technology to enhance stability, minimise dislocation risk, and improve range of motion compared to traditional solutions.

Dual mobility implants feature a smaller diameter femoral head that securely fits into a larger polyethylene insert. This design alteration contributes to increased stability, reduces the likelihood of dislocation, and enhances the overall range of motion.

The OR3O system is a departure from traditional hip implants incorporating Cobalt Chrome (CoCr) components. Instead, it incorporates Smith+Nephew's advanced bearing surfaces, such as the OXINIUM DH liner. This proprietary technology employs additive manufacturing to enhance the hardening depth of the liner.

Additionally, the system uses Smith+Nephew's OXINIUM on XLPE for the femoral head and polyethylene inserts, eliminating the need for modular CoCr components. This design choice effectively mitigates concerns surrounding wear and corrosion risks linked to the alloy.

The introduction of OXINIUM DH as part of the OR3O Dual Mobility System represents an evolution of Smith+Nephew's OXINIUM Technology platform.

The unique diffusion-hardening process employed in OXINIUM DH is achieved through additive manufacturing techniques, enhancing the implant's durability and performance.

The modular dual mobility concept made its debut in India in 2015 and has since gained traction on a global scale. Post-operative dislocation ranks as the second most common cause for revising total hip replacements worldwide, prompting surgeons to seek solutions that mitigate this challenge during total hip arthroplasty.

Clinical studies indicate that dual mobility technology is particularly effective in managing dislocation, surpassing metal-on-metal or ceramic-on-ceramic large head series.

Smith+Nephew's OR3O Dual Mobility System is readily accessible in India for primary and revision applications. Notably, it boasts cross-compatibility with the R3 Acetabular System.

Established in 1856, Smith & Nephew plc, operating under the name Smith+Nephew, is a British multinational medical equipment manufacturing firm headquartered in Watford, England.

The company boasts a global presence as a leading manufacturer of advanced wound management solutions, arthroscopy equipment, trauma and clinical therapy offerings, and orthopedic reconstruction products.

With a broad reach, its diverse portfolio finds distribution in more than 100 countries worldwide.

Recently, In July 2023, Smith+Nephew introduced its REGENETEN Bioinductive Implant in India. With more than 100,000 procedures performed globally since its inception, the REGENETEN implant improved the approach to surgical procedures for rotator cuffs.
