A good warranty should help patients in case of failure


Cornelis believes a good warranty “should include not just a time limit, but also provide for damages in case of failure, as well as free surgeries to correct the problems, or provide for a new implant of your and your surgeon’s choice.” He learned firsthand that hip implants can fail. A good warranty would help inform patients about how long their implants will last and establish a system for patients to use if they need a defective implant replaced.

Cornelis received his first hip implant in 1997, however, in 2005 a revision was performed and a metal-on-metal implant was used. A year later, x-rays revealed that the ring where the ball fits into the hip socket had broken and was sticking into his muscle. In this spot doctors found a mysterious growth about 8 inches long and 2 inches wide. At first, doctors thought this growth was a tumor; but after doing some tests they said it was an inert growth likely due to encapsulation of metal shavings from the metal-on-metal hip implant. Cornelis explained that his body was rejecting the metal shavings from his metal hip but when that didn’t work his tissue would encapsulate it.

In addition, blood tests revealed that he had a major infection in the hip where the ball goes into the socket, which his surgeon thought was related to the failed hip.

Cornelis’ hip implant was removed and for 3 months, he was without a hip and had to administer intravenous antibiotics to treat his infection. After the infection cleared, Cornelis received a new hip implant made of ceramic, which, although very painful, is functioning well. His surgeon said his pain may never go away.
