China NMPA Product Recall - Hip joint prosthesis (cobalt-chromium-molybdenum)

Tianxinfu (Beijing) Medical Devices Co., Ltd. initiated a voluntary Class III recall of its Hip Joint Prostheses (Cobalt Chromium Molybdenum) on August 6, 2019, under the oversight of China's National Medical Products Administration (NMPA). This action followed a national medical device sampling inspection that revealed a significant quality deviation: the disc angle of the connection between the prostheses and the bone ball head pin, specifically from production batch 1700929, exceeded the company's defined technical tolerance limits. Despite none of the 40 affected units from this batch being sold in China, the company took immediate corrective actions. These included sealing all remaining products from the non-compliant batch and committing to a thorough analysis to identify the root cause of the deviation, followed by the implementation of necessary rectifications. The Beijing Food and Drug Administration confirmed the sealing of 30 units, with 10 units having been used for the initial random inspection that identified the defect. This recall underscores the regulatory framework's focus on maintaining product quality and safety standards within the medical device industry.
