Data presented at the American Association of Hip and Knee Surgeons Annual Meeting showed total hip arthroplasty performed with a highly crosslinked acetabular liner in patients younger than 50 years of age was associated with Kaplan-Meier overall survivorship of 93% at 15 years when revision due to failure was the endpoint.
“The non-highly crosslinked group showed 87% [survivorship]. This was significantly different,” said Andrew J. Bryan, MD, who presented the results.
Six patients in the group treated with non-highly crosslinked polyethylene and no patients in the group treated with highly crosslinked polyethylene underwent revision surgery, according to Bryan’s presentation.
THA was performed in 273 patients in the study for indications that included osteoarthritis (62%), avascular necrosis (22%) and dysplasia (5%).
“There was no wear in the highly crosslinked group as noted by our method, and there was no osteolysis in the highly crosslinked group,” Bryan said.
The six revisions performed in the non-highly crosslinked polyethylene group (10.5%) were for wear.
According to Bryan, the two groups’ clinical outcomes were similar.
“The use of highly crosslinked polyethylene led to a significant reduction in risk of failure in patients less than 50 years old,” he said. – by Susan M. Rapp

I realize how difficult this is, but there is no way around it.

Elbow Fractures in Children
in Elbow InjuriesArticle Featured on AAOS
Elbow fractures are common childhood injuries, accounting for about 10% of all childhood fractures. In many cases, a simple fracture will heal well with conservative cast treatment. Some types of elbow fractures, however, including those in which the pieces of bone are significantly out of place, may require surgery. Other structures in the elbow—such as nerves, blood vessels, and ligaments—may also be injured when a fracture occurs and may require treatment, as well.
