Orthopedic Surgeon Lawrence Dorr

On April 22, 2008, Dr. Lawrence Dorr, a renowned orthopedic surgeon decided it was time to inform his colleagues of his results the previous two years with the Zimmer Durom Cup, after he found that 14 of the 165 patients he treated had to undergo revision surgery within two years of the initial implantation. The letter Dr. Dorr wrote to his colleagues is included below.

To: All AAHKS Members
From: Larry Dorr, MD

This NOTICE is to inform you that we have had ten revisions in 165 hips and have four more that need to be revised using the Durom cup (Zimmer, Inc). This failure rate has occurred within the first two years. In the first year the x-rays looked perfect. We have revised four that did not have any radiolucent lines or migration (and John Moreland revised one). These early cups fooled us, but the symptoms were so classic for a loose implant that we operated the patients. When we hit on the edge of the cup it would just pop free. As time goes by the cups begin developing radiolucent lines.

We now have one cup at two years that has actually migrated a short distance. It has tilted into varus. We do not believe the fixation surface is good on these cups. Also there is a circular cutting surface on the periphery of the cup that we believe prevents the cup from fully seating. We stopped using the cup after the first revisions. We have notified Zimmer. The FDA has been notified and we will notify them of our continued revisions.

The company does not believe it should pull the cup from the market so I am notifying all of my colleagues of our failure rate with this cup. I went through a similar scenario with the Sulzer cup failures where I was the only one experiencing revisions at the beginning and basically it was assumed that it was our technique. I can assure you that this goes beyond technique.

I learned my lesson in not informing everyone about this magnitude of failures with the Sulzer cup problem, so it is my obligation to do so with this cup. If you have any questions, do not hesitate to contact me.

Sincerely,
Larry Dorr, MD
