Trabecular metal has a cellular structure that resembles a bone. It also has the ability to approximate its mechanical and physical properties more closely that other materials that are used for prosthetic. The Trabecular configuration, which is unique and very porous, is beneficial to bone formation . It enables rapid and extensive tissue infiltration and strong attachment. This new type of metal consists of interconnecting pores. This means the structural biomaterial is 80% porous. This leads to 2-3 times better bone in growth which is compared to “conventional porous coatings and double the interface shear strength.”
These Trabecular metals are implants that are made using elemental tantalum metal and created with techniques using vapor deposition. Strength and corrosion resistance with great biocompatibility are why elemental tantalum is a great new technology. Trabecular metal is very strong and has a great strength-to-weight ratio. What is very impressive about this metal is that when it is inside the body it has a bone-like physical and mechanical properties. It was proven that after the surgery, 8 weeks later the bone grew and filled in most of the available pore space.
