CHICAGO, Ill. (Ivanhoe Newswire)— About 500,000 total hip replacements are done in the U.S. every year. Even though joint replacements reduce pain and improve ability to perform daily activities and tasks, sometimes they can limit a person’s range of motion. But a particular type of hip replacement is allowing patients full range of motion without fear of dislocation. Dual mobility hips.
Forty-seven-year-old Angelica Kodosky is grateful she can do this. This active mom of two was suffering with hip pain due to arthritis.
“Wake up … pain. Tie my shoes … pain. I stopped doing yoga, which was one of my favorite things to do because, yes, I was in so much pain,” explained Kodosky.
Kodosky knew she would need a hip replacement but feared she could not continue yoga without causing damage to her new hip.
“Certain activities—yoga, Pilates, waterskiing—things that I think could potentially put them at high risk for dislocation,” said Craig J. Della Valle, MD, Rush University Medical Center.
That’s why Dr. Della Valle suggested a dual mobility hip replacement. Unlike a traditional hip replacement where a single ball moves inside a socket, the dual mobility system has an additional implant.
“You’ve got either a metal or ceramic ball, a larger ball on top of it and a metal liner which goes into the cup. So, it’s a slightly more complicated bearing system,” stated Dr. Della Valle.
But the system reduces the risk for dislocation, which is the number one reason for hip replacement failure, and it can …
“Potentially provide the patient with better range of motion to do certain activities that normally we wouldn’t be enthused about them doing that require higher degrees of range of motion,” continued Dr. Della Valle.
Such as yoga. Kodosky did the dual mobility hip replacement and is feeling better than ever.
“I had the life I had before and I’m very happy,” smiled Kodosky.
The operation and recovery for a dual mobility hip replacement is the same as a traditional one. Since there are two bearing surfaces, there is a potential for a higher wear rate. However, Dr. Della Valle says with improvements in materials, the wear rate is still relatively very low for most patients.

MEDICAL BREAKTHROUGHS
RESEARCH SUMMARY
TOPIC: DUAL MOBILITY HIPS FOR FLEXIBLE PATIENTS
REPORT: MB #5001
BACKGROUND: Total hip arthroplasty (THA) has helped evolve how the arthritic hip is treated and is considered to be one of the most successful orthopedic interventions of its generation. THA has been performed for over 100 years. The procedure of THA has helped surgeons better understand the selection of prosthetic materials in certain patient groups. The earliest attempts at hip replacement that were recorded took place in Germany in 1891. The results from this attempt were shared at the 10th International Medical Conference. Professor Themistocles Glück demonstrated ivory could be used to replace femoral heads of patients whose hip joints had been destroyed by tuberculosis. In the late 19th and early 20th century THA involved placing various tissues (fascia lata, skin, pig bladders submucosa) between articulating hip surfaces of the arthritic hip.

DIAGNOSING: Conditions that can damage the hip joint that can make hip replacement surgery necessary include osteoarthritis, rheumatoid arthritis, and osteonecrosis.
If a person experiences pain that persists despite pain medication, pain that worsens with walking, even with a cane or walker, experiences loss of sleep because of intolerable pain levels at night, has difficulty getting dressed because of the pain, the pain affects their ability to go up or down stairs, or has pain that makes it difficult to rise from a seated position, they might want to consider having a hip replacement surgery. Before surgery you’ll want to meet with your orthopedic surgeon for an exam. The surgeon may ask about your medical history and current medications, examine your hip, paying attention to the range of motion in your joint and the strength of the surrounding muscles, or order blood tests, and an X-ray, however an MRI is rarely needed but may also be an option.

NEW TECHNOLOGY: A growing number of adolescents in the United States are undergoing total hip replacement surgeries, according to study findings from researchers at Hospital for Special Surgery in New York City. The results were shared at the American College of Rheumatology annual meeting in with the presentation listed under the name “Use of Total Hip Arthroplasty in Patients Under 21 Years Old: A U.S. Population Analysis” and since have been published in The Journal of Arthroplasty. The finding showed that between 2000 and 2016, the number of total hip arthroplasty (THA) procedures performed in patients under 21 years of age have increased from 347 to 551, while the total pediatric population in the United States have remained stable. Traditionally, most young patients undergoing THA suffer from developmental bone or joint ailments or juvenile inflammatory arthritis, however, the new study has revealed that the upswing in THA procedures in young patients is not being driven by a rise in the number of children with inflammatory joint disease.
