Porous
tantalum is an open cellular structure composed of dodecahedron, similar to the structure of human cancellous bone. In modern medicine, tantalum metal has attracted more and more attention from medical and materials workers due to its unique advantages such as excellent corrosion resistance and biocompatibility, and has been widely used in the medical field.
Porous tantalum metal has 3D porous space configuration, good mechanical properties and tissue growth characteristics, making it a bone substitute biological material with wide application prospect in joint reconstruction. The whole structure of porous tantalum metal is very similar to the spongy bone of human body, and its strength and toughness are higher than that of the spongy bone of human body. Therefore, medical experts at home and abroad use the porous tantalum metal bar as human body implant to treat early femoral head necrosis and other orthopedic diseases. It has been used in clinic under the name of trabecular metal.
