Zimmer Bracing for Durom Cup Lawsuits

Zimmer Holdings Inc, the manufacturer of the Zimmer Durom Cup hip implant medical device, has increased its reserves in anticipation of lawsuits being filed as a result of the defective hip implant device. Initially, Zimmer put aside $47.5 million to cover the anticipated lawsuits but increased that amount by 50% in the fourth quarter last year to $69 million.
In July 2008, Zimmer suspended sales of the Durom Acetabular Component after reports of failures began to mount. The complaints involved loosening of the hip implant device requiring revision surgery. The failure rates are estimated to be 5.7% in the United States with approximately 12,000 implants performed prior to the suspension of sales.
However, in August 2008, the Durom Cup was reintroduced with a new warning and a training program for surgeons implanting the device. In spite of this, some surgeons complain that the problem with the device lies with the device itself and not with surgical technique or procedure.
