Recently, the number of patients with orthopaedic diseases including bone tumors as well as elderly people with osteoporosis suffering from fragile fractures has been increasing. Nearly 70,000 patients undergo surgery with artificial joint implantation. Now more than 80% of artificial joints used in those surgeries are imported and thus bear some inconveniences including challenging intraoperative shaping due to the different bone geometry of Japanese from that of western people. Therefore, we developed plates categorized by size and following the curve, angle and diameter of bone to accommodate the different bone geometry among individuals. We received both US and Japanese patents for these our proprietary products.
