Federal regulators are demanding changes to labels on devices that deliver pain killers directly to joints after surgery, in response to numerous reports of irreversible cartilage damage.
The Food and Drug Administration said from 2006 to 2008 it received 35 reports of severe cartilage damage in patients who were given pain pumps after joint surgery. Nearly all the reports involved patients who had shoulder surgery; more than half needed additional surgery, including joint replacement.
Companies making pain pumps include I-Flow Corp. and Stryker Corp. Makers of the anesthetics used in pain pumps, such as APP Pharmaceuticals Inc. and Hospira Inc., will also have to update their labels. The firms have 30 days to propose language that includes a warning about the potential for cartilage destruction, according to the FDA.
