HIP
OR3O◊ Dual Mobility System for Hip Replacement
The OR3O◊ Dual Mobility System is a hip implant system for total hip replacement. It’s made with OXINIUM◊ Technology, available only from Smith+Nephew.
Overview
The OR3O Dual Mobility System is designed to restore your hip function by replacing the damaged parts of the ball and socket. It’s engineered to enhance stability of the joint1 and made with OXINIUM Technology, our award-winning2 implant material.
What is the OR3O Dual Mobility System?
The OR3O Dual Mobility System replaces the ball-and-socket construction of your natural hip joint. However, it is not a standard hip implant:
Standard hip implant system
A standard hip implant system includes a ball that fits into a socket with a liner. There are three main layers.Dual mobility hip implant system
The OR3O Dual Mobility System includes a ball inside another half ball, that fits into a socket with a liner. This gives it four main layers.
The ball-inside-a-ball design of dual mobility has been shown to provide:
Enhanced joint stability3
Reduced chance of dislocation3
Increased range of motion4
What are the benefits of the OR3O Dual Mobility System?
Dual mobility systems provide better stability and less risk of dislocation than standard hip implants without this advanced design.3
The OR3O Dual Mobility System has additional benefits. It’s made with OXINIUM◊ Technology, our award-winning implant material known for strength and durability.5-8
Studies have compared OXINIUM implants to those made with cobalt chrome, another common material. Results showed that OXINIUM implants offer:
Stronger surface hardness5,6
Greater scratch-resistance5,6
Better wear performance over time7-9
In fact, one study showed that patients who received OXINIUM implants had less risk of needing a follow-up repair surgery than patients who received implants made of cobalt chrome or ceramic.10

Is the OR3O Dual Mobility System right for me?
To find out if hip replacement with the OR3O Dual Mobility System is a treatment option, make an appointment with an orthopaedic surgeon. The surgeon will examine your hip and review your health situation in determining if hip replacement is recommended. Here are other things to know:

What are the risks involved?
All surgery has risks and the potential for complications. Talk to your surgeon about any concerns you may have before you decide on treatment. Some of the possible risks and complications for hip replacement include:
Blood clotting
Blood clotting problems – such as deep vein thrombosis (DVT) or pulmonary embolism (PE) – may occur after surgery and interrupt normal blood flow. Your medical team may recommend medications and exercises to reduce the risk.Infection
Infection may occur at the surgical site or elsewhere in the body. If a serious infection occurs, additional surgery or removal of the implant may be needed.Pneumonia
After surgery, pneumonia or other breathing problems may develop. Your medical team may recommend measures to reduce the risk.Nerve problems
Nerves or blood vessels in the hip area may be damaged during surgery.Fracture
It is possible for the upper part of the femur (thigh bone) to break after the stem is inserted. This may be caused by putting too much weight on the joint too quickly, or by small movements of the stem that can weaken the bone over time.Hip dislocation
Hip dislocation may happen after surgery. The new ball and socket components are smaller than your natural hip, so the ball may pop out of the socket if the hip moves in certain positions. Your medical team will give you tips for avoiding this issue.Implant wear or failure
The hip implant may become worn, loose, or damaged. It may not perform as expected. In some cases, another surgery may be needed to correct or replace the implant.
This is not a complete list of risks. In some cases, you may need additional surgery to address a complication. Talk to your surgeon about the possible risks for your specific health situation.
Disclaimers
All information provided on this website is for informational purposes only and is not meant as medical advice. Not everyone is a candidate for total hip replacement using the OR3O Dual Mobility System, and individual results of joint replacement will vary. Implants are intended to relieve hip pain and improve function but may not produce the same feel or function as your original hip. Every patient's case is unique, and each patient should follow his or her doctor's specific instructions. Potential risks include loosening, wear, and infection that may result in the need for additional surgery. Discuss your implant options with your surgeon. Please discuss nutrition, medication, and treatment options with your doctor to make sure you are getting the proper care for your particular situation. If you are seeking this information in an emergency situation, please call 911 and seek emergency help.
