FDA warns Zimmer over manufacturing of hip devices

Oct 1 (Reuters) - Zimmer Holdings Inc said it received a warning letter from the U.S. Food and Drug Administration citing problems with manufacturing and testing processes for artificial hip devices made at the company's Ponce, Puerto Rico, plant.

The warning letter, dated Sept. 19, does not restrict production or shipment of the hip devices, called Trilogy Acetabular Systems, or require withdrawal of any products from the market, Zimmer said in a regulatory filing.
