Study Finds “Dual Mobility” Hip Replacement Attractive Option for Younger Patients


More than 330,000 hip replacement surgeries are performed in the United States each year. Overall, it is a highly successful procedure. However, as with all surgeries, a risk for complications exists. 

Dislocation is one of the most common complications after hip replacement and the number one reason for revision surgery. A study we conducted at Hospital for Special Surgery (HSS) found that patients who received a newer implant known as a “dual mobility” hip replacement had zero dislocations.  In comparison, study patients who received a traditional fixed bearing hip implant had a dislocation rate of 5 percent.

The research, which focused on patients under 55 years old, was presented last month at the American Academy of Orthopaedic Surgeons Annual Meeting in New Orleans.  

We were especially interested in seeing how the younger patient population fared because they are generally more active and put more demands and stress on their hip after joint replacement, and this increases the risk of dislocation.

Although the concept of dual mobility was originally developed in France in the 1970s, the technology is relatively new in the United States. “Dual mobility” refers to the bearing surface of the implant - where the joint surfaces come together to support one’s body weight. 

A hip replacement implant is a ball-and-socket mechanism, designed to simulate a human hip joint. Typical components include a stem that inserts into the femur (thigh bone), a ball that replaces the head of the thigh bone, and a shell that lines the hip socket. 

Dual-mobility hip components provide an additional bearing surface. A large polyethylene plastic head fits inside a polished metal hip socket component, and an additional smaller metal or ceramic head is snap-fit within the polyethylene head. "Dual-mobility" means that there are two areas of motion, improving the patient's range of movement and reducing the risk of dislocation.

We compared the dual mobility system with the traditional fixed bearing system in two age-matched groups of patients who had a primary total hip replacement over the same time period. There were 136 patients in each group with a mean age of 48.

At three-year follow-up, the researchers found that the patients who received the dual mobility implant had no dislocations. In the group receiving the standard fixed bearing implant, seven patients, or 5.1 percent, had a dislocation and needed a revision surgery.

Total hip replacement is increasingly being performed in younger patients. The results of our study are encouraging for this active, high demand group of patients and may lessen concerns for dislocation. More research is needed to see how dual mobility implants perform over the long term.

  3. Irrespective of receiving daily oral or future injectable depot therapies, these require health care visits for medication and monitoring of safety and response. If patients are treated early enough, before a lot of immune system damage has occurred, life expectancy is close to normal, as long as they remain on successful treatment. However, when patients stop therapy, virus rebounds to high levels in most patients, sometimes associated with severe illness because i have gone through this and even an increased risk of death. The aim of “cure”is ongoing but i still do believe my government made millions of ARV drugs instead of finding a cure. for ongoing therapy and monitoring. ARV alone cannot cure HIV as among the cells that are infected are very long-living CD4 memory cells and possibly other cells that act as long-term reservoirs. HIV can hide in these cells without being detected by the body’s immune system. Therefore even when ART completely blocks subsequent rounds of infection of cells, reservoirs that have been infected before therapy initiation persist and from these reservoirs HIV rebounds if therapy is stopped. “Cure” could either mean an eradication cure, which means to completely rid the body of reservoir virus or a functional HIV cure, where HIV may remain in reservoir cells but rebound to high levels is prevented after therapy interruption.Dr Itua Herbal Medicine makes me believes there is a hope for people suffering from,Parkinson's disease,Schizophrenia,Cancer,Scoliosis,Fibromyalgia,Fluoroquinolone Toxicity
