High revision surgery success rates reported with jumbo acetabular cups

ORLANDO — Although there are some issues to consider when implanting cementless jumbo acetabular cups, a presenter at the Current Concepts in Joint Replacement Winter Meeting estimates he uses them in 95% to 99% of his acetabular revision cases.
“We have a high success rate” with these implants, Paul F. Lachiewicz, MD, said of his group’s published studies. With 15-year survivorship, there was a 3% rate of infection and a 3% rate of loosening.
“You’ll see if you follow these patients long enough, you’re going to have other problems,” he said.
The implantation technique is critical to successful use of jumbo acetabular cups in revision surgery, and the use of screws is practically mandatory, according to Lachiewicz.
He said good exposure is also a key part of the surgical technique and he urged surgeons who decide to use this prosthesis in their patients with bone loss to be cautious when reaming.
“If you are not careful, you could theoretically ream away the posterior column,” Lachiewicz said.
He said pelvic discontinuity is a contraindication for cementless jumbo acetabular cups. – by Susan M. Rapp
