Zimmer-Biomet is warning hospitals around the world to closely inspect devices sent to them by the Warsaw-based company before using them. The company sent out a notice to clients last month after the FDA issued a recall of some parts because pieces of plastic packaging were sticking to the devices. According to Zimmer-Biomet, 730-thousand artificial knee, hip and shoulder implants need inspection, although they claim only about 60 are at risk. The FDA says the packaging is bio-compatible, which means patients are not in any danger if the plastic was still attached during the implant surgery.
