The National Medical Products Administration (NMPA) has granted marketing approval to Suzhou MicroPort Joint Medical Technology Co., Ltd for its zirconium niobium alloy femoral head. This development marks a significant advancement in the field of orthopedic implants, offering a new option for patients undergoing total hip joint replacement surgery.
Product Description and Applications
The zirconium niobium alloy femoral head is designed to be used in conjunction with the company’s series of hip joint prosthesis components, making it suitable for total hip joint replacement procedures. This product utilizes zirconium niobium alloy that adheres to international standards (ASTM F2384) and forms a ceramic-like layer through surface gradient oxidation. This innovative feature can reduce the wear of high cross-linked polyethylene acetabular liners and lower the revision rate of hip joint prostheses.
Advantages Over Traditional Materials
Compared to cobalt chromium alloy femoral heads, zirconium niobium alloy femoral heads can significantly reduce metal ion precipitation and joint surface wear. Furthermore, when compared to ceramic femoral heads, the zirconium niobium alloy variant can reduce the risk of prosthetic fracture and joint abnormal noise, providing a safer and more reliable option for patients.-Fineline Info & Tech
