China NMPA Product Recall - EIUS single-ankle femoral joint prosthesis

Howmedica International S.de R.L., supported by its responsible unit in China, Stryker (Beijing) Medical Devices Co., Ltd., initiated a voluntary recall for its EIUS Uni-Ankle Femoral Joint Prosthesis. This action, reported on October 28, 2011, and subsequently published by the National Medical Products Administration (NMPA) on November 4, 2011, was prompted by an identified issue with the product. The main concern was a higher revision rate for the EIUS single-ankle knee joints compared to other typical uni-ankle knee joint products. However, the company's investigation concluded that there were no underlying design or manufacturing defects contributing to this elevated revision rate. The recall specifically targets markets outside of mainland China, including Argentina, Australia, Brazil, Canada, Hong Kong, Japan, South Korea, New Zealand, Singapore, South Africa, Taiwan, and the USA. Crucially, Howmedica International S.de R.L. confirmed that no affected units were ever sold or distributed within mainland China, thus rendering specific recall actions unnecessary in that region. In line with the regulatory framework, the NMPA requested provincial, autonomous region, and municipal food and drug administrations to reinforce their supervision and management over similar medical devices.
